Real clone Alonso-PD
2 Attachment(s)
Hi all and Happy new year
Many members knows few years ago i build a clone Alonso-PD This old "amateur clone" i use many-many mods for find the best balance between all stage. But is not enough for me. Last months i start again experiments. My "target is... I try work with the same method use by Alonso for calibration omega-coils and feritte all together with standard schematic publish here from qiaozhi without any extras. I find this method and i build a "real alonso-PD clone" with all parts. My prototype now can detect a very-very small magnet-piece 2 meters distance very easy and a micro transmitter 433MHZ more than 50 meters distance. My clone has not false signals from South-north magnetics lines and with calibration knob i can calibrate machine very easy in search-area In my test-area work perfect, but i need make tests with unknown area and ofcourse video's with unknown targets This knob for calibration and very small mods (low-bat section, power supply section) are the only extra's The truth is that the calibration is too difficult and now i understand why there were failures to construct a truly clone Here some pics my prototype Heltkit section and feritte section work together without extra selection switch. Output signal from feritte coils is very-very low and feritte section now, work without overload signal. Next days if i have free time i publish here more infos and i start video's with prototype I want to thank a forum member here ( very good electronic engeneer ) , because, with his help and testing , I managed to find all the problems encountered best regards |
andreas excellent job. you are using ferrite and omega coil together? can see the regulator calibration for the ferrite, it changes the position of the ferrite coil?

Hi Andreas
And happy new year Congratulation. Seeing nice work , I hope more success for you .:) Best regards |
Alonso Scheme for PD is the best here. Thank you to all who have actually worked on and do some modification and updating. such as Qiaozhi Eteban and Morgan and other.
Good luck my friend Andreas. and I hope for you a good result in all the world. the transmitteur and receiver 433MHZ and the right choice my friend. well you advance in this field. 433 MHz is used in the detection by the magnetometer. Look this picture details and link www.parallaxinc.com http://www.kounooz.com/up/do.php?img=1735 http://www.kounooz.com/up/do.php?img=1736 If you need help for higtech you know my email. |

With ferrite "out" of coil is more easy to null the signal of passive receiver. But original Alonso;s PD is different.

...and the ferrite appears to be placed in the null line (as described in Chapter 14 of ITMD) I have not your book, but feritte is not placed in the null line. Please remember my old message, we have ONLY a "magic place". In this place, output feritte-coils has only 0,1-3mv output signal. For this results, i use a micrometric moving system and ofcourse need fine null omega together (move -null omega and again). This point is very difficult. We need repeating tests, before protection this place Regards |

the gap produce sometimes false signals. My opinion. Never we have see a real photo, about feritte (gap or not). I think "the gap" is false infos for stoped some members build it or present a myth I think "original feritte" work with complete core. I use complete core, because has stability out signal Second i believe never members open the original coil in feritte. A x-ray photo yes, but destroy the place and open never I have this sense, because.. if you have a unit and work , you don't touch :nono: somethink and stop work. The interest for all is this "magic point" is +/- 0.1mm. Tell me Quiaozhi, can you find this point with your hands? Personally i cannot. In this case my clone with micrometric regulator i think is better original Conclusion. Members that say they know or have opened or know exactly how is the original, i think say "guess - tales" and they publish bla-bla and dreams. If they knows really , few years ago, they start build and sell units. This is only real true. regards |
Quote:
If the original Alonso PD has a split core, then I suspect the ferrite nearest the TX coil is acting similar to the nulling coil in a concentric arrangement. Since it is not driven by the TX oscillator, and relies only on voltage induced into the coil, this would explain why it is very difficult to find the balance point. |

This whole ultrasensitivity adjustment way described here is for laboratory only. Its useless because if the voltage will drop from 17,995v to just 17,985v it will be already out of balance again. Same with temperature, moisture, electronic parts and especially harsh treasure hunting conditions like weather, electro-smog and many other factors. Under super stable conditions you also can built an usual metal detector that is extremly sensitive. But at real treasure-hunting everything is anything else than super-stable. btw. it would be much more clever to fix and construct the part with the 2 coils first on a extremly solid basis (melt it into plastic or resin etc.) and afterwards you find your needed zero or whatever EM-field window for the ferrite-coil by electronical adjustable components like variable capacitors, mini-coils or whatever. If this point is so critical and easy to bring out of "center" you must work with a programmed microcontroller which controls and readjusts the needed values automatically. A lot measurement with a 10meter rope works perfekt, but only if there is no wind at all. |

You are confused. We have drop or not if unit don't work lab this is correct. In this case i have put a microcalibration pot for setup again. Please study my pics. On panel i have a calibration pot for it. If you cannot understand me my method, don't worry Funfinder wrote it would be much more clever to fix and construct the part with the 2 coils first on a extremly solid basis (melt it into plastic or resin etc.) and afterwards you find your needed zero or whatever EM-field window for the ferrite-coil by electronical adjustable components like variable capacitors, mini-coils or whatever. If this point is so critical and easy to bring out of "center" you must work with a programmed microcontroller which controls and readjusts the needed values automatically. I have not time for explain more. But you must be sure, if put a microcontroller this clone don't work Funfider i build this clone for personal study and use. For me is a "pratform" for understanding method use by Alonso (if he.... build this machine). I am not interest search or find more about "Brasil method" detection for long range. I am not interesting for sceptics if... this unit work etc etc or not I am only happy, because after few years, i publish the first real clone. Later if i finish my study with this unit i send this unit gift... a good friend mexico. Maybe if he want publish results with this myth. You knows, this is not my choice For me is only a personal test for find method calibration. My "cup" is many-many members says ".. i build it", but i am sure now, on they dreams ofcourse build it regards |
Quote:
On many occasions skeptics are accused of having no personal experience with LRLs, so this was also an opportunity to push that accusation to one side. All the information concerning TOTeM is provided in ITMD, and nothing is hidden or made purposely confusing. Other members here have built TOTeM, and one has even created a PCB to replace the original stripboard layout. It's an intriguing device to use in the field, and often you can appear to be following a "signal line". However, I leave it up to each experimenter to arrive at their own conclusions, and to modify the design as they wish. :nerd: |

Few months ago, i build a greek-project name english-PD. I see the same results a small magnet detect 5 meters distance and a very small 433mhz transmitter very easy detect 50 meters distance. We have the same results. Strange is .. if we have perfect calibration and detect only small piece magnet, units cannot detect magnetics lines from earth. I try understand more about ferrites with coils. Maybe i find a theory for this, but is not time explain more regards |

Later i publish full schematic (is same posting by Qiaozhi) and a pdf file PCB for all members wants build it for experiments. My mods are very small for stability. If i have free time, i make some video's for look all members why i say "this is a real clone" regards |
Thanks Andreas for sharing and posting this information, and continuing with constructive elements and experiments.
This is finally neutral and technical information, whatever are the results they will be useful and interesting. :) |

As you can see ,this is original schematic publish by Qiaozhi with very small modifications regards |
All this tinkering, discovering, helping together here concerning electronical issues is ok.
As long as the info doesn't leads us "real results wanting" persons away from the serious track. I self built and tested one of those Zahori circuits which mainly are based on electrostatic so afterwards I knew with this stuff you can find electricity lines or rubbed air-ballons from a good distance but no treasures. I like tinkering but it was still a waste of time and ressources - just because some people here suggested this "could work". And the same it might be with the ToTeM or the Alonso Clone.... btw. I am not a "skeptic" which condemns everything completly. First some persons here thought I would be a LRL-believer and now some may think I am a skeptic. I am also nothing in the middle, I am a realist who controls everything exactly, compares how much truth a story really could contain and I work with very fair warrants. This world or better the own personal life will always be full of decisions and judgments of what it is good for me or others and whats not. It is not just to make their lifes hard if doctors, judges or even politicians have to study first. Complex and sophisticated things need alot background- or special-knowledge otherwise people will fail with good work or correct results. Shure, I could start to experiment with those circuits, too, but why I should find out completly the same as we know already? And what we know is not really convincing if it comes to real treasure-hunting. If we see the whole thing as a development-process then it's useless to test the same stuff over and over again. But the motivation to contribute to this kind of "not really promising stuff" would return if there should popup really promising results. Do you know what is CW? It is "continuous wave". Do you know SSB? Its Single Side Band. Why do I ask? Because with special ham amateur radio transceivers you can hear ultrashort bandwidths of just a few Hertz thousands miles away. It is no big deal to create ultra-sensitive detectors - its pretty simple today. But those must work for the intended purpose. This micro-adjustment stuff shows already clearly that we have a very ultra-sensitive receiver of some sort. And of course ultra-sensitive detectors react on minimal EM-field chances, be it a magnet or a 1.5v spark 5 meters away. Just the question is: For what it is really ultra-sensitive and under what stability conditions? This here is a forum about metal detection an not radio-station-LRL-detection. It is not about the Hubble telescope which is ultra-sensitive for super far away stars. So the question is: How useful is this kind of supersensitive-detector for metal? For metal buried under ground, otherwise we may find it with some field-glasses, too. ;) Or in other words: Its wasted time to experiment with ultra sensitive radio-receivers if those are not good for metal-detection. I'm pretty shure the ToTeM or Alonso is some kind of BFO which only reacts on metal or magnets because the coil-activity or inductivity is extremly very slightly changing (on a level of just a part of 1 Hz, it could be even just the shape of the wave-form which gets slightly disturbed or interrupted for some time), even passivly if a huge metal object already interacts with some long-wave frequency. Thats also the reason why those both coils have to be so extremly well adjusted. To make it more clearly: Those kinds of detectors may listen at the 50.000 Hz area but they could see the difference of 50.000,012 and 50.000,025 Hz at a certain frequency (the 50KHz was just an example). btw. first it would be really important if you know on what kind of detection-principle this stuff is based before you experiment with it. I guess I gave you now the answer, so you know with what kind of supersensitive detection circuit you are dealing and now you can find a way to modify it until it's really useful for treasure-detection. Perhaps it would be better to start with ultra-sensitive BFOs directly - making "tabula rasa" (clear table) and not messing with such "pre-ready-made" circuits which contain alots of disturbing and unneeded content. And if you need a handholdable metal-detector better buy a Garrett Ace 250 including snipercoil an mount both on a just 30cm long pole. As long as those "longer range detection" doesn't work reliable and on a clear level concerning on what kind of influence it really reacts, this 2in1 circuit is just hindering important improvements. You also should input the schematics into some circuit simulating software so you may see under which kind of EM-influence the coils etc. will react on what level or intensity. Or do we wanna have this whole riddle-guessing going on and on for years and years? For the moment all those ToTeM-, Alonso- or PDK detectors seems to me like bad AM-Radios which will receive all kind of household-disturbances, too, because they are not shielded and designed the right way for only receiving what they should receive or detect! But perhaps you're already on the right track and by clearing things up and improving stuff on the right area we finally get some reliable "more distance metal detection". And without the possibility of receiving intense and highly directional buried metal signals - without radio-activity almost impossible, especially if those targets are very small - some kind of highly sensitive or for a certain area specialized detector would be an absolutly must! |
Funfinder, I agree with your assessment. As a Professional Treasure Hunter/Salvor When I first started testing and encouraging development of Frequency Discrimination methods in 1980 there was adequate hobbyist metal detectors on the market that would detect coins & jewelry at shallow depths. Not much was available for the Professional Treasure Hunter,or Salvor, so we would make modifications, or try to come up with innovative solutions of our own. This is when the Frequency Discrimination from a distance to detect deep buried Treasure Trove was born and implemented.
My interests is in detecting large Treasure Troves buried deep underground or under water where conventional Metal detectors lack the depth penetration to reach the targets I am seeking. Although technologically primitive by today's standards, the first MFD's I used throughout the 1980's were fully electronic, both transmit & receive. I was fortunate to have enough inventors interested to provide me models to Field, and comparison test. My intent and purpose for Frequency Discrimination was never for detecting small ,shallow depth targets, it never has been, and is not now. So I have no pony in this race for LRL shallow depth detection except to point out the Skeptic Con game the owners of this forum are playing on it's contributors and viewers. I applaud those who are making an effort to discover, and share with others a viable method to make a workable, shallow depth, discriminating LRL, that has universal appeal to hobby metal detectorist. It's a huge market, but will not be won without a fight from those with a vested interest in the lucrative Metal Detector industry It is understandable that those EE's & Techs embedded in the system that earn a substantial income from the hobbyist Metal detector industry would be concerned about the increased interest and growth of a concept they don't understand in a competing industry. With all best wishes, Dell |

Hi Andreas you can use this PD without ferrite or change it by transmitter 433Mhz is better. I improve it.

In fact, we're so scared that LRLs will take over the market and make conventional metal detectors obsolete, that we operate a website dedicated to LRLs, and even freely publish designs such as the one above. :lol: |

Hello Andreas
Bravo and congratulations to this beautiful project. :thumb: I want to learn more about PDs and will try to build your PD project. As a first project I built the TOTeM PD. Unfortunately I have a little problems with false signals in the north - south direction and contrary the same. Your clone AlonsoPD will be my second project and hope something more to learn about PDs. Maybe I can thereby transfer some mods in my TOTeM PD. Thank you for sharing your knowledge with us. Best Regards Goldmaxx |

Hi Andreas Please check the Two Transistor it's proper? The Correct: NPN transistors require a positive base signal to energize (forward bias). |
Quote:
This is correct. Original PD has D4,D6 diodes 1N4148. I replace with two NPN transistor work "as diode" if unconnect base With this tip we have more temperature stability , because NPN protection inside plastic case and we have the same result. R22 use for stability pot C4 use tantalium. If you have not connect serial + - - + two electrolytic capacitors 22uF U4 use only 78L05, because Lseries has more power supply out stability Cx remove.. is not important Led2 use a hight bright yellow LED is better for this stage If you have not R6,R6A=680K you can replace 1M Other tip. If you have note D2,D3=1N60 you can replace with RED LED!!!!!!! Yes my friend, a poor Red Led (no high bright) work as diode perfect if frequency is < 3MHZ regards |

Then J1 in Pcb for transmitter is connect to Trans +9V :rolleyes: and not in J1 for supply 18V dc it's for battery.:nono: That is your error. I cant understand the two name for J1. sorry Thanks |

Is very clean JI (on PCB) is for connection batteries (two serial 9V=18V) Trans (on pcb) is for connection +/-9V transmitter Later i publish all connection with a diagram regards |

Mr. ANDREAS.
Can you help me? How to do MV Alonso TX coil? What will be the diameter of the coil, the coil wire diameter and number of laps will happen? Thank you. |

Hi all
Next step is omega-coils attachment PDF Note1: Original schematic publish Qiaozhi has for Tx coils 12+5+3+12. If you seePDF my omega has 12+3+5+12turns. This is correct. We need high peaks RF transmitter with low-level modulation signal for better calibration If we work with 12+5+3+12 turns TX coil you have 100% modulation signal 400-800HZ with 12+3+5+12 modulation signal has level 45% Note2:The dimensions are critical , if you want a properly nulling regards |

Hi Andreas here the image of my omega coil and i have much images of my prototype but I need some help to finish this project I have done many tests with many types of omegas and ferrite coils but I can not achieve to detect a coin at 50 cms as morgan says so I would like might help a little, I think I'm just a bit close to it and I could make the PD detected a magnet at a distance but I need even more distance also able to detect the two components of the phenomena electric and magnetic components.
Here is a picture of the omega coil according to the ohmic resistance pointing by Morgan, I think I'm wrong on some things but I think the whole secret is in the type of turns of the ferrite and the omega maybe i think i am near of make work the Pd alonso. |

I think your problem dear wiliams are the location of your coils
Firstly you do not have the zero point between the coil they are almost in the same axis we must shift second one must have a good calibration at the coil with ferrite. it must be adjustable and mobile |
Alonso PD
I do not understand what you mean with that william or axis of the coils.
and you observe a position at which the ferrites are with respect to each device omegas?:???: I think this is the correct position as established by alonso pd. SALUDOS. |

Hi, I mean with >>>>> Wiliams Tim Williams, but I did not write that wrong sorry I do not think dear Tim becaufe the magnetic chapms are parallel mean overlap. So to have a zero points must be moved one of them is the omega coil low ferrite or down as I have represented on your photo Look Pd Totem that is 100% correct and this picture by andreas and ferrite adjustable for calibration |
PD
Are you sure?
let me experiment this again though I've done before and when separated much the ferrite antenna from the omega nothing magic happens, but I'll try again with omega coil did in a different way. But I would also like the opinion of Andreas or someone else For the confusion.... don't worry I send you greetings and a strong hug LRLMAN. |

Your desperate commercial gimmick to your book is pathetic. Revise you schematic and honestly tell it that thing can possibly work as LRL for gold or whatever buried metal? Besides, ask that dude who bravely took the chances to build it, if he found anything to date besides random noises? Gotta go. See ya on tour with your 'black sabath'.:D |

I also have a problem with green led, this does not turn, I do not know if the pcb is something wrong or has led the polarities reversed. in the device of 6 pcb from alonso, I have dificults to increasing distance detection of a coin with switch in central position working ferrite-omega but the PD of a single pcb as the Greek Forum, the problem to detect the coins to more distance is less with a distance of a 22 cms with good iron discrimination. I have a videos i send to qiaozhi or someone else for upload. Greetings Dr. Hung |
Please relax. We have time, step by step we can see all false infos present here from......, about this PD. For example extreme detection a coin. If healthkit receiver work with stability etc etc.
I publish this thread, because i believe is time open a myth and publish here the real possibilities. |

I like that Andreas I really liked what you said is important to know all the details of this machine to see if in fact if it works or not, I need to finish this project. I also want to tell you that I have been testing with the PD that which have a single pcb and I detected very erratic way an object buried beneath a planter at a distance of 10 mts, about it i checked the place with a normal metals detector on the spot where the buried object is that the object appears to be large. LRLMAN. |
BEGINING
Ok Andreas and friends,
Where do we start? for the list of the components of each pcb? or the preparation and calibration of the ferrite, or for the preparation and calibration of omega antenna? Want to do it here....... or in RS? Please comment. LRLMAN |
Quote:
Anyone can confirm the maximum signal receiving feritte-coil in this place . I will try to make videos to show that the signal actually becomes zero. You can see that the position is not :nono: "TOTeM has the ferrite placed in the null line of the TX ...", as reported by Qiaozhi. If we put feritte in the null line of TX, we have not stimulate omega coil via feritte. In this case we have not on condition regulate all together. As you know i am not RSforum member, because old time i have many attack from "guru's members knows all :lol:" and they don't publish more infos, because they believe, with own informations i can build a commercial project. This is a joke for me, then i delete me from RS The true is, this members never build it, because, if they build it members start a commercial project. In this case the best choice for me is publish here all infos about PD and your RS forum you can have help, by guru's for more infos about nulling and calibration feritte together with omega coils. If you have not help in RS forum ( i am sure for it), i can start again. regards |
Friend lrl man.you found object connected omega coil and ferrite or only omega coil?
|
PD
This sounds good to me andreas we need to start with this and see what happens.
I've seen the videos that you have exposed in your youtube channel about your PD and you can detect some objects and all this is very interesting, I see a video clearly showing the detection of a small magnet and I like a little since my PD also detect a magnet but just to low distance. Greetings. LRLMAN. |
Posision of ferrite regarding omega coil
Quote:
Where you think that Dr. Hung would place the ferrite regarding omega coil???? which type of ferrite? because I believe that he was used a different ferrite that was used by Alonso in hes proyect, because the ferrite Alonso used was two flat ferrites and the used by Hung was rounds. LRLMAN. |
Quote:
As I said, I can not know what kind of metal is because it is located below a large round planter and I can not destroy it. And the PD, must be connected the ferrite-omega together. The only position of omega working how a metal detector. LRLMAN. |

For specific feritte, I use turns in the Plan. I believe they need depending on the magnetic permeability of each feritte we must be experiment with turns. For my clone i use a chinese feritte from AMradio orthogonal 100mm. Yes with microcalibration horizontal axis actually finds a "dead hole" with zero signal. About y axis, i think we need small luck:rolleyes: Now if we find the dead point and put a 4n7 capacitor pararell with L7 we can see omega coil need caps= 1n+6n8 and receiver coil need 1n+1n8 for best resonate all together in xxxKHZ Upon verification of capacitors that have the same values as the original plan, we are confident that we have created a clone, working with exactly the same values parts. I repeat again, the big problem is find this "dead point". I believe Alonso knows exactly the frequency and made arrangements in the Act. I have this opinion, because the location has put feritte (real PD) is ....with hot glue.In this case, maybe he knows near zero-point area and he find the best with practice regards |

So to keep it technical, I can say he would probably put it on top of a calculator, or attached to a piece of string and "feel" it pointing to the golden ring or statues he planted nearby. Nothing useful as you can see... |
Quote:
what do you think about the final principle of it ? The way you explain it, it look like you are building a very compact kind of two-boxes detector, finding an extremely tiny null, very close to the Tx loop. Do you think it could be? And that a detector in such a configuration has something special? |
Quote:
Only to tire people's hands. for both boxes nothing special. and only for gold. ansi we do not know what prices are I think this is unitul unless it is at least a long range. So it becomes a bit special as traditional. I'm with you Fred about this quetion |
Quote:
Yes this unit has something special. With this special null, unit detect very easy magnetic piece. My first experiments, unit detect very easy aluminium piece 6 meters distance, 30cm depth (i don't know how old is this alu-piece) and the strange for me.. if detect magnetic-piece unit stop detect magnetic lines from earth. Joke is ... with perfect calibration all together coils-housing detect one euro ONLY 12CM DISTANCE. I remember some members say here.. unit can detect a coin 20,30,40..cm distance. Maybe detect capacitor-phenomenon via hands and believes detect coin, because if don't make fine calibration produce this capacitor phenomenon. For me this unit has many interest points and work same method other unit "name englishPDfor gold" I try find free time and fine weather for external tests regards |
Hi Andreas,
Between PD and the Crypton, which is better in terms of range of detection? Regards... |
Quote:
we have two units with different philosophy. I cannot find something same, only alarm circuit is same My opinion. Many -many engineers try build alonsoPD withouts results. Only a greek engineer build a PD (name magicPD), but he use only receiver helthkit with a big ferrite (without feritte-coils) and maybe have small results. Few months ago, i build an other myth (name englishPD) with perfect results. In this case i use a special feritte, because englishPD the secret is the special feritte. Now i can see AlonsoPD and english PD has same philoshophy (method detection). If i understand well ..what happen inside , for me is possible 30% build a PD only for gold. I have a personall theory, but sometimes i have not answers for my questions.. who knows! I know only one now, this extreme units need special CAD labs for produce same results. In this case i understand well now, why amateurs cannot build, but only with luck sometimes build a real unit. regards |

Thanks Andreas.
As I said before, and by your observations, it also looks like the PD could work on the fluxgate magnetometer principle... Some said that the magnetometer effect should be nulled out to "work" properly. However, the main question remains: What is "working" ... Attachment 18784Attachment 18785 Quote:

Hello Andreas I like your project and would like to add something. I'm no electronics expert, but with CAD its not a probem and can help you. If it is helpful, I can construct you a 3D model with exact data of the Clone AlonsoPD with all what you need and place at to disposal here in the forum. So it could be everyone watch, or measure it himself. What do you think, that would be a helpful? Best Regards Goldmaxx |
Hi Goldmaxx
I like your project and would like to add something. This is not my project , i build only a real clone I'm no electronics expert, but with CAD its not a probem and can help you. Thank you very much about your help. I have not problem with CAD, because it's my job, the problem (not for me), but others members is.. they have not machines work via CAD for build materials If it is helpful, I can construct you a 3D model with exact data of the Clone AlonsoPD with all what you need and place at to disposal here in the forum. So it could be everyone watch, or measure it himself. In this case i think you need a cdr file (corel) by me and with this file you can make a 3D model for. I think this 3D model can be helpful more members regards |

Hi Andreas
Thank you for the quick response. I can construct 3D CAD model and create a 3D pdf file from this model. A 3D pdf can anyone who has the adobe reader (latest version) installed open and watch it. You can rotate the model, zoom, represent parts in show or noshow and the most important, measure the parts and distances. I think it is helpful for anyone here in the forum. Quote:
If it is helpful, and it's okay for you, I will send you my email, so can you send me the data. At that time, I've made for the Totem casing one. I post it here again, and you can test it. If you open it, first click with the left mouse button on the image to activate it and then you can rotate it with the left mouse button and zoom with the right, or scroll wheel. At the top of the screen is the toolbar, you'll find all the tools to measure, make cuts and everything else. Have fun with it. Regards Goldmaxx |

My PD
Andreas, Another thing, the omega coil that I did, have the followings sizes :
TX: 8.5 cm diameter with his small center of the omega have 4 cm diameter magnet wire of 0.30 mm (0.29 mm here in mexico) with series 9+6+5+9 turns. RX: 4 cm diameter, with magnet wire 0.20mm with 26+26 turns. The turns that I put to the TX and RX antennas, was because morgan gave the values measured in ohms and only with those amounts of turns and the measures of wire magnet i could get that values, I could never get those ohmic values with the type of magnet wire and amounts of turns that morgan said. |
Interesting post, Fred (fluxgate mag)
Back in the 1980's I build a bipolar pulse induction metal detector that worked fine with an air core searchcoil. I replaced it with a ferrite rod "probe" type searchcoil and was surprised to discover that it had become very sensitive to earth field-- I'd inadvertently constructed a fluxgate magnetometer.

Andreas,
I also have doubts about the position of the ferrites with respect to the direction where this points in cloned prototypes, if you look.... all ferrites are always pointing to the wires that going in the direction to the TX and RX omega coil, electronically has something to do this for a good detection of this device? see next image: |

Hi Andreas Sorry for so many questions about, but the questions are many to finish this PD properly and to see if it work or not,.. if not then stop this project.
although the idea is to start make a different omega which that I have to advance in this PD. I have some more questions about the omega image: |
I think all these questions are very important for making a perfect omega with some accuracy in order to give the PD a high performance.
|
Today (nw i am out my base), i export a PDFfile scale 1:1 via CAD. You need only print this and you have real dimensions for omega coil and Rx coil

Yesterday I connected to PD an Omega coil equal that which morgan exposed in RS for his device but not detected little more distance than the omega I did, only 12 or 15 cms distance for coin similar diameter to 1 Euro OMEGA MORGAN: TX: 5-2-2-5 and RX: 14+14 or 30+30 all magnet wire was to 0.15mm handling this wire is very difficult, this is very thin |

Hi Friends, Hello Andreas,
I tell you that i did the coil exposed by Andreas but without good results this detects much less distance than the omega coil I made earlier, I've been looking a lot of information about how to make an omega coil and reviewing many images and found in my papers a document to Andy Flind where is the way to make a bobin omega compensated for a metal detector and catches my attention because this omega Andy has other features elaborate and I think this could help us develop even on a smaller scale an omega coil but need help from someone here on the forum who can do calculus to make it equal to that of andy but in a smaller size perhaps about 8 or 9 cms. diameter this is important because the omega coil exposed by Andy I think this well balanced in its measures as should be a real coil omega because maybe this can work well in the Alonso PD. LRLMAN. |
Quote:
Alonso PD don't work as a real MD detector, but as LRL If you replace C4 (see #116) with value <10nF, you have more distance detection. Ofcourse with C4=100pF... 470pF you have best distance detection. I made this clone with the true values of the components posted here few years ago. I saw this is real "distance detection" of omega-coils when everything configured correctly. In this case we have a real LRL and a "poor" MD. You can ask the morgan. He has the original PD, he know well the real distance detection and measurement real frequency tune. If he publish real infos (Rs forum), i don't know, because, i am not member My opinion... he never publish real infos or he cannot build a real clone (i am sure for this) If we want a better MD section, ofcourse we can replace with other schematics. I think later i replace this section Regards |
hello guys, put the tx in lrl detection, help for a little most distance range, and most directional precision, too for most centre habilities, but any persons say, the tx near of the metals point, due hig tension oscillations can null the field of electrons around the objetive buried, how a short circuit, then you see all signal dissapared, morgan say the tx help for can be detected in minor size objects

Ok Andreas, Well then where we start again? I need you to know some things about my experiences with the developing of my PD'S before starting with all this. 1 - I have two PD, one with six PCB’s and the other with a single PCB as presented in the Greek forum ok? 2 - The single PCB PD is more stable than the six PCB’s. 3 – In the PD single PCB I put two flat ferrites Alonso identical to his PD pistol. 4- In the PD six PCB’s, I put two round ferrites of 6 cms. long each one by 1 cms thick. 5 - The schematic I used for the two PD’s was exactly the same in RS by Qiaozhi version 1.20 because it had corrected the polarity of the capacitor # 33 uF 10. 6 - the omega coil and ferrite were made with almost the same omhics resistance just with different calibers magnet wires (for coil omega only) because the coil ferrite I put the same type of wire 0.30 mm but with a different turns quantity to that exposed in RS ; It is important to say that the way that I did for winding ferrite was different from that presented in RS because with the turns exposed in RS never detect a small magnet or just to 1cm away from the ferrite, but with the new way of laps that I put on a ferrite, this detected the small magnet to 20 Cms. away from the ferrite, and only when the PD is working together Omega-Ferrite; I've also noticed that the magnet is detected by the omega, in only omega mode, but only in a shorter distance away maybe about 7 cms. 7- When I adjust the two PD's and pointed toward the ground, the pistol beeps in direction to the soil detect the capacitance of the soil and I don’t know if this is normal or how can I fix this, I've been seeing information exposed by Esteban about it but i don’t understand what he says of how to correct this detail; Esteban says: “We can find a good compromise between the both (sky and soil)” and he say that I have to change wire the ends of the RX: “Invert extremes of receiver coil and put your hand in both sides of rec. coil, time by time. You note in one extreme capacitive effect (a kind of null) when you put your hand. If the capacitive effect is produced in down part (this is, a kind of null), invert the connections of the extremes of the rec. Coil. Is better the increasing of audio in the down part when you put your hand, this is, the part of rec. Coil near the soil”. This efect is normal or not? Is good or bad????? 8- I notice that in the two PD's green LEDs do not light at any time and in any way and I think that something is wrong may be reversed polarity of these, could you help me a little on this? maybe with some schematic correct, and as I was saying I have no knowledge of electronics I understand very little I'm no EE here in México I'm just business manager or public accountant but I am very interested in completing these projects, not for sale of devices but for personal use because I know many places here, which might have some interesting things to discover. I have seen with my own eyes what they can do the Alonso lrl’s when he was here a few years ago I am sure that these well calibrated equipment can do good things 9- The PD one PCB have a potentiometer multiturn 50 k. 10- The PD Six PCB’s have a potentiometer one turn 50 k. All this is to begin to get an idea of what I did, I would like you to show the full Schematic in one piece or as exposed by Qiaozhi since I have some confusion regarding the schematic that you exposed in the area of the coil connections to omega, because the RX of Qiaozhi Schematic of 1.20 has three wires and i see only two in your schem., and TX coil has 5 wires which I can’t see on your schematic, i only see 3 connections. Anyway I will try to analyze it with the schematic of Qiaozhi. Regards. LRLMAN. |
lrman and all, the sky-ground effect was for me a big problem when i building the pd whit rx & omega, the original pd circuit are very versatile, whit other coil recipes, then also you have a great diversity of present phenomens whit each distinct maners of make your circuits or power measures, lrman i am in chihuahua mexico but today no have very much time for my lrls or experiments due my busy particular works, the sky effect can dissapared changing whit other coils recipes, also the sky effect automatic dissapared when the pd go at stabilzed function, then came devenue sensitive stabilized lrange detection, the pd have very much secret of operations semms easy but isnt sometimes

Last year i have a mail by seden if is possible drawing a PD only for gold.
This is a point very interest for me and ofcourse i try find solution for this. For experiments i use my real clone alonsoPD with full modifications (for example change MD section with other circuit stability), build a new sensor via lathe and laser cutter. After two months study and build many-many prototypes sensors, i think find solution. The big problem again is calibration all together. In this case i use other way for find delicate for all work together. Joke !!! i know very well what i need for calibration and all steps for fine tune, but in practice after three days without results, i find solution (very difficult) Please look video https://www.youtube.com/watch?v=1alv...ature=youtu.be This is not dream, but real. No ground or sky effects. No detections earth lines The unit is very-very stability and silence for other metals. Interest is PD work without motion or very-very slow motion enjoy |

I know PD can detect three very small gold-ring and a gold coin two months old buried, but is not enough Notes here. I understand now , why some members (top engineers for me) cannot build one. Here we have a mix electronic and cad with critical setting all together. Please look again video. My prototype has many external mechanics regulators for find best points in practice I understand now why never build a real clone by members. Sometime i believe the original PD has not a perfect calibration, because with hands and a electronic lab cannot make this. Αbout detecting magnet. This is not really criterion, because a perfect calibration PD has low SENSITIVITY for all external sources The second half august. I send prototypes for full testing other countries. If they have success, this is a first real world long range detector only for gold. best regards |
Hi Andreas
Very good work, I followed another path for my LRL and I do not have many opportunities to tune only the gold, I have already changed the internal oscillator frequency from 3 to 10Mhz without appreciable changes. But I have a question, are you sure that the revelation of gold is only a general decrease in sensitivity as the gold emits a signal of greater intensity than other metals? Best Regards |
Quote:
Thank you very much Negative! gold don't emits a greater signal. I am sure now, this signal is lowest, But if i understand well, we have here a "tuning fork" in a very small range band frequency. In practice, my PD have not low sensitivity, but reject all no interesting bands via a strange filter design by me. I know well all members try find a formula with experiments to false or not false. But here need more. The time is near after ten days i can know more. best regards |
Hi Andreas
If I understand correctly your filter passes only the "phenomenon" generated by gold. Do you think your filter also works with other types of lrl? For example my LRL? I have tried different filters on my LRL placed between the antenna and the input of lrl, I tried different types of diodes, silicon, germanium (even the old style contact tip called a cat's whisker) and also the Schottky type, I also tried various capacity capacitors in series with the antenna but I had no results. Surely you have made a breakthrough in the understanding of the phenomenon. Best Regards |
If I understand correctly your filter passes only the "phenomenon" generated by gold.
Correct, but i need more time , before i am sure. In this case i have program send prototypes other countries for more experiments Do you think your filter also works with other types of lrl? I don't know. Logical don't work. LRL with passive receiver cannot use this method, but later i try.. maybe i find solution if is possible For example my LRL? I have tried different filters on my LRL placed between the antenna and the input of lrl, I tried different types of diodes, silicon, germanium (even the old style contact tip called a cat's whisker) and also the Schottky type, I also tried various capacity capacitors in series with the antenna but I had no results. Correct . As i write last posts, we have a mix electronics and mechanics design. Critical is micro setting dimensions. For example +/- 0,01mm. Surely you have made a breakthrough in the understanding of the phenomenon. Interesting for me is... phenomenon work with full discrimination. Sometimes i think ... this is a dream. Sometimes i think .. my eyes "see" false results. In this case i play again video and i try find my false. I have "lost my sleep" before i make a final test date 15 august for sure. best regards |
Hi Andreas
Should know something more about the "phenomenon" in order to distinguish gold from other metals. I also spent a lot of time to try to learn more. Since the phenomenon is revealed by Lrls that work with different principles you may think that it is acting on "broadband", that his energy has magnetic properties, electrical and optical properties, or perhaps more. Which known energy has these features? You talk about micro setting dimensions and this suggests to microwaves and infrared, and also to radioactive isotopes. On the other hand the low frequencies of operation of Lrls suggest also to a low-frequency component of the phenomenon. The isotopes gun of Dr. Bickel was based on the principle that the metals buried many years emitt isotopes that can be detected at a distance. Maybe he was talking about isotopes because he did not know or did not want to reveal the nature of the phenomenon. His instrument was very similar to a magnetometer and could be used by an aircraft in flight, so it was very sensitive. Moreover, each metal has an emission of isotopes that is different from the other metals, it is a sort of signature that allows to discriminate eg gold from other metals. If this is true it is no doubt that even a LRL can do the same thing. Best Regards |
My friend Andreas.
I believe that what you have done was building a mechanical filter nulling adjustment to position the ferrite in a similar way the front loop RX coil is required, to avoid ferrous metals in relation to the omega TX coil. Tough this might work at some extent and reject ferrous and some non ferrous metals, if you do not employ an added bias filtering specific for gold, it will be very hard for you to eliminate silver, copper or bronze. This mechanical adjustment of ferrite is a primitive way of selecting only gold, when a much better and hassle free procedure is to electronically 'trap' its 'magnetic signature', if you know what I mean. Also, since a LRL is to be taken in the field under hard conditions and subject to bumps, a mechanical adjustment of key components might well get ruined very easily. My schedule is still too tight but I hope soon I will be able to show here the couple of devices I have been developing including the MX8, with a kind of technology I still have not seen in any LRL so far. Cheers. |

Nice to see you it will be very hard for you to eliminate silver, copper or bronze. Please look again video. I have not signals from silver,copper or bronze.

I make a real test place with all parasitics and scraps and of course very near 220V ac camples ... is a primitive way of selecting only gold, Of course you are correct. The best way is hot-glue as we can see inside orginal PD by Alonso. In this case use lathe , lazer, cad ,pcb program are primitive when a much better and hassle free procedure is to electronically 'trap' its 'magnetic signature', if you know what I mean.

Hi Andreas
It 's very interesting especially the revelation of the gold bracelet to more than 1m or 2m. This means that the "phenomenon" is also active for gold that is not underground. Also in this case the sensitivity is greater in the direction south north? Best Regards |

Do you think deserves to construct the PD; Is it difficult to work it? ευχαριστώ |
Do you think deserves to construct the PD;
Yes deserves, but it's very difficult. Original by Alonso is the base, but calibrate together all is difference. I explain more. My first results and experiments i "see", few years ago, before build the first real clone and publish here. If you remember i publish here ,my first posts this thread "....i am sure this is clone and later i start experiments outside lab..." but my firsts experiments outside all setting positions don't work and PD need again calibration, the other place need again calibration and again and ....etc etc. In practice we have a unit with other setup for all places and don't erase magnetic lines by earth. Now this problem solved. My opinion original PD is best of best LRL for all old buried metals without discrimination, but all steps for perfect calibration need long time and ofcourse you know well what do you want about calibration. Maybe this is the true "why never this PD start mass production" by first designer if is Alonso. Modifications for Gold is other. Need filters, ferrite with special specification etc etc Now about some amateurs for example our country they say "i build it and work and i find gold etc etc...." i believe fantasy is perfect for ....mind Is it difficult to work it? It's easy with standard steps-calibration on place by user Να εισαι καλα |

We believe that the FG80 or FG90 not work in relation to the PD? A talking about the same manufacturer. thanks. |

My sense is strong. In this case i am "free" use some parts without license. But if i am false about my opinion, we have only one "brake" for mass production. This is the long time for calibration. For example i want (PD without discrimination) minimum 10 days for calibration. This long time need for calibration all together and choice between many-many ferrite (same parts-number) the best for use. In this case need small luck for find the best parts for one PD. Regards |

Hi Andreas,
thanks very much for the effort and great information here. I want to build this Alonso-PD clone and spent many hours in this forum to collect all that spread info. Its really a pity because some information is confusing and messed up and also sometimes contains erros. Therefore many beginners don't know how to build the device and get frustrated. I want to try to fix it but I need a little bit of your help. I want to put the whole project into 1 Zip file for everyone to understand and build the device. First here is the partlist from both schematics (Mainboard & Transmitter Board): MAINBOARD (Real Clone Alonso-PD) http://www.longrangelocators.com/for...ad.php?t=18956 LED LED1 = LED2 = high bright yellow LED3 = CAPACITORS C11, C22, C32, = 1n C23, = 3n3 C24, C27, C29, C30, C38, = 10n C19, C34, = 22n C12, C16, = 47n C15, C20, C31, C33, C35, C36, C37, = 100n C14, = 220n C4, = 10mF tantalium.

Calibration is not the problem. I don't know how to connect the parts correctly. Im also really confused I've found error on Transmitter PCB versus schematic.
Capacitor C4 is placed wrong on PCB and R7 is not existent. We really need a diagramm with all parts connected together to locate any possible errors. I will try to complete the connections in the picture from post 184 but I need help because Im not sure if thats correct. Here is the error I found on transmitter board PCB: |

After digging through all the posts and threads on this forum I've found the answers.
This is my final wiring diagram Rev. 1.1 2014. If someone finds any errors please let me know and I will update it. Daniel |
I had good results with alonso 5 pcbs combination with coil heatkit gd 348..estou working on it
|
I made this lrl last year with the same configuration above but does not give a promising result. True, this lrl is very sensitive to the phenomenon but is not stable, it drifts from time to time. So the operator should re adjust the sensitivity oftentimes.
Regards... |
This is the fault where we have so much amplification in DC. As with the metal detectors you need a button for retune or a motion amplifier.

PDK Housing
2 Attachment(s)
Here is my PDK housing for the Alonso Clone. I needed some good housing to do the calibration exactly. I've designed my own housing in AutoCad Light and used my DIY CNC Router to create the parts. Now I have to search for an approriate Ferriterod.

You might have problems with coordination. |
Quote:
Thanks. What do you mean by coordination? Each coil can be moved by small increments for adjusting. |
Quote:
Probably ferrite coil should be more center pointed in regard to omega coil. |
Quote:
You tried to do something that can be moved left or right to do what your settings correctly. |
is that have someone finish successfully this project
|
Quote:
No, the ferrite cannot be moved left or right in this design. But if it is absolutely necessary I can modify the design of the ferrite holder and cnc new parts in a couple of minutes. I used the measurements from Andreas's post 81: http://www.longrangelocators.com/for...1&d=1391447412 http://www.longrangelocators.com/for...1&postcount=81 |
Quote:
and therefore I tell you some things. It will help a lot in this coordination. And as far as possible fixed structures, because easily detuned. I will recommend you for the reason that you have the technology in your hands, and you can do a good job, I will recommend to the ferrite to create a micro coordination. so that you can restore the coordination Assists per moment where it should. |

Hi Daniel.
Congratulation for your fantastic design:thumb:. You must know that at original Alonso's PD, Omega coil looks at top of housing (you must turn it 180 degrees). |

Hi all
Sorry for delay send about more infos for PD. After experiments, three months ago, i see PD need new circuits design. I make new design with new extra circuits for more stability , filters etc. Attachment inside PD a photo. I hope next week i have final experiments of course video etc. About reject magnetics or soil lines, ground effects, full rejection all metals except Gold, rain, AC camples 220v, temperature etc, has been solved. About searching without motion or very slow motion PD work has been solved. best regards |
hi all
thank you very much Professor Andreas for sharing your projects, I realized your pd but I encountered some problems 1- my setup works as a Pulse induction because it detects all metal 50 mm 2- both led blinking but no sound only if I connect the Q4 collector to the resistance R40,maybe the 555 timer is blown I do not know please help me thank you in advance |
Quote:
PCB and schematic have not error. I am sure 100%, before publish here and of course first prototype work with this. I think you have put "bad part" or put "invert" 555 My opinion. Check botom side pcb with your eyes, step by step for problems Check soldering if are correct and final replace 555 and Q4 with new The best choice is .. use osciloscope and check all sections if you have a friend electronic engineer best regards |
accept my respectful greetings ANDREAS teacher and thank you I'll check and change the IC 555 and T4 and attach images and video of the printed circuit

hi teachers andreas
I finished my PD after your help, it's true calibration is very difficult but ultimately this circuit detects all materials and unfortunately he can not discriminate * anyway thank you for your cooperation and support. and if you could, there he has a solution for discrimination ?? Thank you in advance and please accept the most respectful greetings to your student |
Hi
First for all I am not master-teacher-proffessor etc. Simple Andreas is enough About discrimination is simple. Remove receiver coil and invert back-front. Now if start again fine null you can see you have discrimination. That's all best regards |

PD pistol is not my design. First present here from morgan few years ago.
Qiaozhi finish full schematic after opinions and studies from many-many members. I must send a thank for members j-player, esteban, Qiaozhi, Aft etc present info without secrets. This PD has a magic for me, because, few members try build it complete without results. Morgan is the first member, build working only ferrite stage. Men in my country Greece build the MD section without fine results. Of course many members build complete this in their fantasy. It was a personal challenge to finish it complete. Only one member with substantially help me and I will again send a big "thank you". This is generally the story. After first really experiments and full modifications a suprise for me is.. PD detect only Gold. This is a big chapter, but i cannot publish more. The lesson is one. If you try, you can build your dreams. It's easy if you can study with open mind. Please don't forget with OPEN MIND best regards |

Hi all
PD only for Gold it's ready. Need only final test this month, of course with videos. I use only one stage from original PD Alonso nothing more. Very small size and weight, full stability without humidity problems or sky-grounds effect. Now need only fine weather and small free time. Note: For now it remains a prototype, I have not decided yet what I'll do best regards |

ALONSO PD ALL CONECTION
1 Attachment(s)
Quote:
Already I conected all pd elements but does not work as I interconnects. how do you see the image of the interconnections present here of the wires going to the receiving antenna seems that there are good? what about the zero point calibration must be done first of all of the transmitting and receiving antennas if everything is connected directly and in conjunction with the ferrite? that is where I have the problem. LRLMAN. |

And what about the interconections of all elements?? are fine?? respect to the image??? I don't know how interconnected the TX and RX, for me it's not good the image, i have a problem mi PD not work. And what about the ferrite?, how can work the ferrite? do you think if i make a short circuit with a 1.5 v, should detect it the ferrite? to know if this is working? May be tomorrow I upload a video of my Pd Working. Greetings. LRLMAN. |
All my posts are very clean. All my schematics are correct. Read again all posts and try.

Quote:
I DID REVIEW ALL INFORMATION AND NOTHING, JUST I DID WORK THE OMEGA COIL, BUT I ASK IF ANTENNA FERRITE MUST ALSO BE WORKING?? I REVISED ALL COMPONENTS BUT I THINK MISSING SOMETHING MORE BECAUSE THE FERRITE ISN'T WORKING. IN ALONSO PD IS EASILY TO KNOW WHEN THE ANTENNA FERRITE IS WORKING WITH ONLY MAKE A SHORT CIRCUIT 1.5 BATTERY WITH A ROUND WIRE 20 CMS. LONG, OR WITH A TELEVISION REMOTE CONTROL, BUT IN THIS NEW PD NOT HAVE ANY SIGNAL WITH THE SHORT CIRCUIT AND I THINK IF IT IS NORMAL ???? SO WHERE IS THE ERROR? IN THIS NEW PISTOL DETECTOR I NOT SEE WERE HAS THE SWITCH POSITIONS ONLY FOR FERRITE OR JUST OMEGA OR BOTH. ALSO I THINK THAT YOU NOT BEEN CLEAR ENOUGH, BECAUSE ONLY THE MEMBERS OF THIS FORUM ARE SUGGESTING ALL WITH IMAGES, WITH LEGEND THE POSITIONS OF ALL COMPONENTS OF THIS EQUIPMENT AND THE PROYECT IS YOURS AND IT IS NOT OF THEM. SORRY ANDREAS. LRLMAN |
Hi LRLMAN
I build clone with all parts, all stages as you know and publish here. Calibration is very-very difficult and critical If you have not tune all together this PD cannot work. i see clone can detect a spark only 40cm distance , a magnet near 50cm distance and ofcourse metals on air maximum 20 cm distance. TV control i think detect 20 cm distance Now if you want work with only feritte, if you want detect a spark xxx distance, this is your choice build it. For me is a pratform for better results About if i am clear or not Ofcourse i am clear. ofcourse i publish my first unit here and i say this is a real clone with small mods for better stability. ofcourse i publish here a fine PCB for all members if they want build and experiment with this. Now if you want method for full calibration or more, i think some members publish here can build this. In this case you can ask there Now about PD only for Gold I use only one preamp stage by clone alonso and new circuits by me (you can see my last photo inside PD only for Gold) Pd only for gold cannot detect metals, cannot detect sparks, cannot detect magnetic lines etc I am very clear. I publish here a thread "real clone alonso PD". I don't publish here a thread " how you can calibrate and build a clone alonso for your step by step". In this case some extra infos via my posts is a gift for every one try build one Best regards |

My presentation of this PD was done in same box shape as much as possible dimensions is what properly, with the original schematic and very small mods for more stability. Of course I use the same box as "platform" for my PD only for gold. After finish all experiments and anything need more, i put PD only for gold in a new design box . PD only for Gold is not free regards |

Dear ANDREAS
how much the price you sell this pd |
2 Attachment(s)
A fine circuit, need and special case, for ergonomic search and easy calibration by user. In this case i must draw a new box for put all electronics circuits, ferrite etc. I think after ten months am ready with new design circuits as you can see, my post #218.
I don't use the original PD box, because i don't like this classic design and more ,because i have problem with with vibration between base "coils housing" and main box. Need only fine weather for external tests. Inside lab PD can detect very easy Gold if put a place after 30 minutes. Very delicate unit, produce a "trust" by user via calibration and see with eyes the real detection Gold. Need small time for solve all small problems enjoy |

I know you not give it purpose I build it without problem .... thank you Andreas this is life :D:D |

can you put your new pcb for us here to try it? :frown: |
Hello Andreas.
I tested my PD on real object from 4 years ago in 2m depth. It can detect signal from 7 m away from target . See it from here. http://www.felezyaberoj.com/?p=4372 |
LDX FOR GOLD
LDX is designed for gold but it can detect other materials like LEAD too.
You can see my test from here. Also i tested PD,Mole prospector,ldx with the same results LEAD is about 5kg in 2m depth and from 4 years ago. http://www.felezyaberoj.com/?p=6796 thanks for your cooperation and helps |
Is LDX static field locator like zahori
or radio frequency reflections like PD or termal locator like LZR kaabi |

Quote:
I would suggest building TOTeM, which is fully documented here -> http://www.longrangelocators.com/for...ad.php?t=19245 At least you will be able to determine if it works as designed or not. As stated in the Conclusion: "Unlike the original PD, the TOTeM project is easily rep- licated with a little care and attention. It easily passes all the laboratory-based tests used by LRL experimenters, and cer- tainly appears to react in the same way as the device shown in the internet videos. Whether it will lead you to treasure or not is maybe another story, but at least you will have the opportunity to explore the pseudo-scientific world of long range locators for yourself, and make up your own mind on the matter." |

Read about such coil tunning at Geotech forum (TGSL project par example). You you need to search zero signal at scope (coil nulling) by carefully mowing small middle coil (RX) over "inner ear" part of bigger coil (TX). http://longrangelocators.com/forums/...1&d=1326275639 |

hi tnx WM6
how to connect scope to circuit for veiw waveform to nulling rx and tx coil? |
3 Attachment(s)
What sort of scope do you have?
In general, with signal tip of scope probe you check certain circuit test points (I propose you 6 specific test point in bottom attached PD circuit) to check individual circuit stages on working status (red line is of scope probe tip - ground probe clamp is always at the same point/ground). Ground clamp of scope probe should go to circuit ground for check of all marked test points. You need to set proper vertical sensitivity (voltage per division) in scope channel used and proper scanning time. You should follow the same test logic (test on working specific circuit stages) with all circuits/schematics. |
i want found zero signal in rx coil
|
CH1 probe to RX coil wire (probe tip to blue wire, ground clamp to black(ground)) wire.
Tunning (nulling) perform by carefully small mowing coils sections apart to each other. CH2 probe can be attached to TX coil wire to mutual control of TX stage working. |
tnx alot:):):):):)

Hi all
After three years of testing experiments etc. PD only for Gold is available on the market. This PD have two models. 1. PDGOLD for detection only for gold and Gold-alloys. 2. PDSILVER for detecting only silver and silver-alloys. For more information you can visit our site www.crypton.com.gr You can see official presentation video https://www.youtube.com/watch?v=JbuVt9rnr78&t=17s best regards Andreas |
ALONSO PD
Hello Andreas I have a question about Alonso PD'S....do you know if the alonso pd must be a Magnetic??? or magnetic receptor???
If it must detect magnets or magnetic fields and at what distance should detect small magnets and if the electrostatic ionic phenomenon has a strong magnetic component to be detected at a certain frequency and some distance by the Pd ?? Best regards. LRLMAN. |

Best regards |

OK thank you very much; I ask you all this because I have some doubts regarding the true LRL of Alonso which has brought to sell to mexico to some friends searchers and which we have tried with success in some searches in Mexico and I have seen and I have tried these devices and i put a magnet in front of them... they can detect any magnet at close distance and can also detect any source of energy at a short distance with the exception of the Tesla coil which is more an HV emitter and infrared receiver. Best regard. |

Hi Mr Andreas, i want to ask a question to you, The yellow area on this Picture is secret? Won't you share it in this forum?
Thank you already.. Regards.. |
Maybe Andreas put a different pcb when he take pictures of his PD. Take note that His PD is already for sale at high price. Do you expect him to give us the correct modification? I'm sure not. The picture is not the original Alonso PD but a general modification.

I can not calibrate coils, I need ideas, comment ...
|
According to Andrea's calibration procedure, you have to move the ferrite first to find the null, then null or adjust the Rx of the omega until both the ferrite and the Rx nulls. Repeat this procedure to obtain the best position of the null. I do not know if this is the correct procedure but this is the tips he gave us. I do not even know if which either the rx coil or the ferrite are responsible for the long range detection.

Hello,
dear all. Is there anyone here that have bought andreas's PDGold or have experimental information about the machine? For exp. Testing the PD in a real target or any successful news. If yes, please share it. Thanks. |

When we connect power and before calibration what is reaction of PD? Can we hear any sound from speaker or lighting led(s)? Best Regards |
Error PD
The problem I have is when I point it to the ground it beeps and when I point it to the sky it beeps. Detects a coin in front of the omega coil, the ferrite antenna can detect a TV. The circuit is correct but I think I have some error that I can not correct.:angry:

I am sorry, my English is weak. I use the translator.

I think Andreas made a mistake in the IR configuration, so the correction is in the Forum ;)
|
my Andi flind LRL work well , Thank you Geo :)
|
Krypton 4 is goldPD or obmd?
|
|
Do you build this machine with this shematic ?? And what is the frequency to calibration ?? How khz ferrite and other coil..
|
Funny scheme turned out. Cloned the clone . I wonder who invented it ???
|
Quote:
thank you for your collaboration but in this scheme there is no adjustment of sensitivity is this normal ??? |
Quote:
I see that the RX part is the well known "passive receiver" with the 555 beeper. The RX coil probably is based on the Alonso PD ferrite configuration. |

Sensitivity is the convergence and spacing of the gold sample of ferrite

More info on our telegram channel:@izaaclrl Mail: isaac308gsxr@gmail.com |
This device (izaac pistol detector) was built on the basis of Alonso's PD and we were the first to succeed in this project.
https://youtu.be/UH1jBnFYhZk More info on our telegram channel:@izaaclrl Mail: isaac308gsxr@gmail.com |
seems to be interesting, but does it discriminate against non-ferrous metals?
|
Yes, it's a lot better than non-ferrous metals. In this case I will publish a new movie.
If the ferrite is not adjusted properly, it does not make any difference between the metals, but if properly adjusted, the non-ferrous metals will have the best reaction and will react to poor ferrous metals. Come to see our videos on our telegram channel. |

Inductance of the ferrite coil and paralel capasitor to him You will set for around ( the nearest ) Radio station for example : ( the nearest ) XX Radio station transmitt in 59.941 KHz , now you will set your Receiver coil for him with this calculator. https://goodcalculators.com/resonant...cy-calculator/ |
you mean we set our LRL near Time signal frequencies ?
and how for those who are very far from Time signal broadcast ? can we set our LRL on LW radio station ? |
Quote:
|
I think we do not need stimulation if we have the ability to detect a radio station with our LRL, do you have the same opinion?
|
Quote:
|
I built a very sensitive LF LRL, I can search with a variable capacitor between 50 and 100 kHz, it captures any station a hundred miles away or very weak electric phenomenon :cool:
|
I know that the stimulator increases the sensitivity, but if your LRL is very sensitive, no need
|
Quote:
And LW radio signal is with very noisy , it's hard to work on it. |
not LW , it work 50-100Khz

i have other version with stimulator , it react near ferrite freash gold and silver , and not reaction to iron

Quote:

it's new version not yet tested outside , it does not react to the spark, I think it's a disadvantage :frown:
|
is it necessary to work to react a spark ????

Thank you my friend !!!!
|
I have a problem :frown: , when I bring the stimulator closer to my alonzo receiver the LED goes off , but when i try with my receiver it stay on ,
I think I need a faster stimulator for alonzo receiver ? can you post a schema ? |
Which model with Alonso PD you build .
|
|
without coil paralelle capacitor and without stimulator it detect sparck 1.5 battery from 1.2 meter

why without parallel capacitor the distance is 1.2 meter and with the capacitor it decreases?
I need a stimulator schematic ??? |

When you take cap from paralell Coil . Your coil not is without Cap. , Input of your Device have self capasitor . pf . and with it have on high Freq. Resonant . Khz , Mhz. |

Good day
As many, interested in ? Alonso PD ? which is modified and dedicated by Mr.andreas Christi Built one and studied. Above all, I must say that Mr.anreas Christi from Greek is an honest, hardworking, social person and his device works, but I think works regionally. Depends on conditions. Here is the result: Alonso-Andreas PD can NOT detect either old buried or fresh gold target from far in any regions or area. There is NOT any zero or magic or golden point which can be tuned by plastic screw or other micro stepping adjustment technic. Ferrite rod and a coil, obviously result a radio signal receiver and Mr.christi accidentally Is receiving some sort of signal (probably UHF) which has effect on Gold target. PD transmitter has NOT effect. What does it mean? If you notice to recent product by Christi (pocket gold detector), it is just a receiver In UHF band and has no transmitter. Means, if you live in an area which there is not any UHF band signal transmitter, your PD can not detect any gold target from far. PD transmitter produces approx. 180 KHz sinusoidal frequency. (it is much like damped wave) Receiver by capacitor value in schematic, tuned to approx. 77 KHz. (75 KHz to 79 KHz variable by moving coil on the rod) Do you see any relation between those numbers? (personally I do not) also there is a 15 Hz low-band-pass filter in the receiver circuit which does not let other higher signals pass to detection part. Overall, do not know what UHF frequency has effect on fresh and old gold target and why this Contact produces 15Hz and below. (beat frequency or ?.) But I think without UHF in your area, no hope to your PD able to detect gold. as myself in iran-shiraz city, which since several years ago, UHF signals stopped by TV channels and all became digital. Also, I informed that there is no UHF TV transmitter in the middle east. at my country very limited Still in the capital. Other area is empty. So, not only your home-made PD will not work in all regions but also factory-made may not work. Important: UHF concept and effect, borrowed from andreas Christi videos published on youtube. Any comment, appreciated and welcome. Please correct it if I am wrong. Thank you Here is a few pictures: |

PGF170 Gold Detector by Andreas...

Hi GOLDEN LILLY , So like only Receiver in UHF Band , Does works good or Find any Buried ? You Try this device? |
Quote:
Does anyone have inside Photos from PGF 170, for analyzing Works method or prencibe ?? Can share here ... |
according to its size , I'm sure it's an IR optical system !
|
Quote:
it is not IR optical detector. he says device uses UHF band and by noticing to video, it is clear that the detector is just a receiver which i think it uses available transmitted radio signal in the environment. TV stations transmitter signals or other sources, i do not know. but it seems to be RF receiver. |
Quote:
but we can guess some there is a knob on the box and first he turn it until tune device the position of knob is seems to be variable capacitor such as available in MW or SW radio. also he says if gold target is less than 5 gram, device can not find it seems density of target is matter and size of surface is not important also he says it is short range detector something around 2 or 3 meters from target when put these signs together, i think the result is a kind of RF detector which uses high power signals which transmitting by radio or TV stations |
Why You thinks that use UHF freq. , can also use so like RF receiver MW or SW band ,
İf this Detector is from only UHF Receiver , then will use any UHF fix Freq. and special Filter only for precious Metals , I think so . And knob can Variable Cap or Potans for Threshold gain . |
good day
Here are a few measurements. hope to be useful for who interested to study Alonso-andreas PD. Please notice that written values are all approx. values depends on ?measurement device?, ?how to wind coils? and ?what size of wire used to?. Anyway, in any condition, I do not think the result will be out of the ?given range?. It seems presence of ? UHF ? signal is vital for device to work as a long range gold detector and Just by making and assembling, device just works such as normal metal detector and not as LRL. Once again: the UHF influences is taken from a video by Mr.andreas Christi, which is about ? pocket-size remote gold detector ?. This video available on youtube at his channel. Here I must say: many thanks to Mr.andreas Christi from Greece also special thanks to Daniel for wiring diagram. Here are a few pictures: |

so in conclusion ,the Alonso PD is no-motion and detects very big metal sheets etc. I'm asking this because I had this "strange detection distance" with the ToTem (tuned in limits as you say). |

two ferrites..
adjustable between them |
Quote:
66 KHZ receiver or transmitter? if you notice to values given and written on the schema, by calculation other frequencies will appear. practically as i measured by oscilloscope, not much difference in calculation and in performance. something is missing in alonso-andreas PD. there must be an "extra factor" which has crucial influence that PD need it to work and detect even fresh gold under ground. http://s13.picofile.com/file/8401357..._frequency.jpg http://s13.picofile.com/file/8401358..._frequency.jpg here you can see 181 khz which measured by oscilloscope.my device http://s13.picofile.com/file/8400775..._tx_signal.jpg |

but I don't remember Morgan or Esteban saying that this PD detects fresh gold. (is here, in this forum, or elsewhere, such a statement from them?) |
the Alonso PD locate a gold sovering 8gr in air test 30 cm

Personally ,for sure, I would not classify this 30 cm, as a long range detection. |
THE ORIGINAL ALONSO PD
Quote:
see distance I get in a silver bracelet buried at 40cm 7 years ago, 6 meters https://www.youtube.com/watch?v=wlU1t2C7Rs4 |
Quote:
To be more clear, 30cm detection distance on air test, it's not a long range detection for this "fresh" gold coin. Simply it's the expected distance from a typical metal detector. In my opinion, Alonso PD is not a "fresh gold" detector, regardless of the advertisement of some clone makers. |
