Here is a pistol project which shows a complete circuit diagram including some modifications that Esteban made to improve it. See here: http://www.longrangelocators.com/for...ad.php?t=11674 You will see there is nothing missing. And there are many tips for how to build this LRL in the thread. You can see the full circuit diagram here: http://www.longrangelocators.com/for...8&postcount=45 You can build this pistol and take it into the fields to test it. I did not build this pistol, so I will not be able to help you with tips. You can ask your questions from the people who posted this pistol where you see the pistol thread. Esteban does not post here any more, but you will find several other people there who built this pistol to ask questions to find more tips to make it work better. Best wishes for your pistol project,  J_P Last edited by Qiaozhi; 01-26-2012 at 08:59 PM.

Everybody can clearly see the Zahori is a pistol: What is your reason to say this is not a pistol detector? Did you never read the posts in this thread? http://www.longrangelocators.com/for...ad.php?t=11674 Are you making jokes for the LRL forum to waste the time of people who are trying to help you?

I can see you are a believer that a locator that detects metals will work long range when you put it in a pistol. Maybe this is true and maybe no. I see many people make pistols that will detect metal, but they have problems for finding long range. I know of a circuit schematic for a detector of metals that works by transmitting VLF radio signals very far away from the pistol, then uses a receiver coil to listen for some changes in the signal that is being received. This locator is so sensitive that it must use a nulling adjustment as well as a sensitivity control for finding signals that can originate in very distant locations. This circuit was designed by some top electronic engineers in the USA many years ago, but it was forgotten. What most people do not understand is this locator does not use integrated circuits which filter out the tiny signals that modern designs cannot find. But LRL experimenters know better. They know how important these tiny signals are for locating treasure. They know these signals are lost when they use modern components. This is why so many LRL experimenters look for this circuit. I have seen many different versions of this circuit with different transistors and components ... and they do not work for most people who build it. Maybe this is because they do not use the correct methods for building their PD. Or... maybe it is because they do not have the correct schematic version. I hear rumors that the pistol has a difficult time to work when the parts are changed for modern parts. But I have the original circuit design using the original transistors and all the original components. Some years ago I read that one of the Geotech engineers has this original locator design made into the pistol project. He did not build a copy using modern parts. He has the original locator from 30 years ago which he modified into a PD without changing any components. He never will tell how much treasure he found. I am thinking he found many ancient hammered coins, but I do not think he will tell if he found some Celtic gold treasures. I don't know for certain because he did not say what he recovered or not recovered. But I remember he said he received some very strange signals that he never received from any of his metal detectors. Then he became silent. We never again heard about any more treasures he found... I can only guess he spends his spare time treasure hunting using his original version PD locator. Maybe he wants to keep the original design as a secret so only he can use it. But I will tell all details...!!  You can look below for a complete schematic. Nothing is missing. It shows all the original parts that you will see if you open the locator and look on the circuit boards. There are very few of these original locators left in the world. People buy them as soon as they are listed for sale, so you will not be able to find one. But you can build a copy from the original parts, because I show everything below. Note: one transistor is no longer manufactured, so I put the substitute transistors that you can use to get the same results. Also, you will need to find a mica capacitor. You can find these on ebay. Good luck with your PD that detectors metals J_P

Great work J_P, keep posting such nice and scientific based projects. Congratulations.
mineoro boxes are only funny and false non-working copies of your design. Not to mention rangertell, okm bionic, hung drain hoses and other fraud crezations.

Thank you for your compliments, but this is not my design. I only drew the circuit diagram of the parts that can be seen inside the original locator. Some very good electronic engineers in the USA designed this circuit, which was said to be cutting edge design work... ahead of its time. But I have heard rumors that some people who work at Mineoro have copied this design, and changed some of the parts before selling it. Remember, this is very similar to circuits that people pay many thousands of euros for, but this design was working to locate metals for everyone who used it. But these are so hard to find an original commercial version, that people will build their own copies so they can have one. Besides being very sensitive, this design also uses completely unshielded VLF loops so none of the faint electric signal components will be lost. We can be sure that if there is a treasure signal in the air, we will receive it... both magnetic and electric..! But there is a problem.... I have an error in the circuit. I am making corrections now and preparing more tips for building this classic original version of the locator. I will post corrections as soon as they are finished. If anyone spots any errors above, please let me know so I can include them in my corrections. Best wishes, J_P

You are correct. It would be more stable if we increase the value there. But remember, we are not looking for stability. We are looking for signals that other locators cannot find. Since there is no Faraday shield on the coils, we can expect to get extra electrical field signals even on the magnetic wave receiver loop. We would not want to lose these electric field signals in a filter cap. I remember when the Geotech engineer re-arranged this same exact circuit into a pistol, he was amazed at the signals he was detecting that he was never able to find with his other locators. He tried every way he could think of to understand exactly what these signals were. But in the end he was satisfied to know that he was detecting mysterious signals that he could not detect with his other metal locating equipment. Since the original parts in this locator use 10nF, we must keep the same in order to preserve the original design, and not take a chance to spoil the detection of tiny signals by making modifications. I should point out there are a few changes in this circuit from the original, because some of the original parts are no longer made. In cases where the original part cannot be found, I substituted a part that works identical to the original, without trying to make a change the operation. Quote:
Yes, these are the same rumors I heard. But it cannot be the same because it has a meter and two control knobs. Of course, I know nothing about the Alonso PD except people say much of it was copied from other engineers designs. But keep in mind, this is a reverse-engineered original factory locator showing the exact components that can be seen inside on the circuit board. Nothing has been changed except a few parts that are no longer available were substituted with equivalent parts. I copied these parts from photos of a Geotech EE's original factory locator circuits when they were available for me to see. So what you see here is the genuine factory model of this locator --- not a modified circuit. The corrected version below shows more details of the parts and it adds another filter capacitor that was missing. There may be more corrections before we have the final version. I think I found all the errors, but I don't know the meter value. It may be a microammeter that has 1 milliamp for full scale movement, but I don't know. We can experiment with different meters to find the correct meter. I am told this meter is very important for finding the tiniest of signals that you cannot hear. See below for corrections. Good luck building the PD and happy treasure hunting, J_P

I am not suggesting to increase, but to decrease value of those C (from nF to pF). OK, I can agree with your intention to follow original design. My word "stable" was someway inadequate, I mean stable sensitivity to usefull signal, not forced stability on TX signal (locked frequency). No problem, I support original design you posted. What about PCB?

Yes, I see your idea. But keep in mind, this capacitor does not carry the detected metal signal. This capacitor transfers a small amount of the power from the TX coil to the RX coil for fine-tuning of the null. We already have the 5K pot to adjust the strength of the null compensation which passes through this capacitor. If we make the capacitor smaller, then we will lose our ability to make full adjustment of the null to arrive at a truly null RX coil. A smaller value here will only allow a very small part of the nulling adjustment which we need for a good null. The actual metal signal arrives as a VLF signal that the RX coil tunes from the air at the same locked frequency as the transmitter. The small amount of TX power that passes through this capacitor is only used for trimming to a true null without needing to move the position of the RX coil. But your concept is good for people who want to experiment with mods farther down in the signal path after the first 1K resistor. Once the signal is properly nulled, then we could take a smaller signal which has all the tiny spikes, and use extra amplifier stages to examine the small signals closer. This is for people who want to make mods. For now I agree, we should present the original factory circuit which is capable of detecting some very strange signals without mods. I think this will be the basic circuit that all modifications are derived from. The PCB is copyright, so I cannot publish it. But I can see where different components are located, so we can keep the components in a similar location as the original, and devise our own circuit boards. I am thinking that any PCB we design can be very close to the original if we keep the components in the similar location. We should be able to arrive at equal performance to the factory-new version of this metal detecting locator. There are some components which are intentionally kept in certain locations to avoid interference from the VLF transmissions and reception. I think that if you were to make a circuit layout that is much different, then maybe you will lose the great detection that is found in the original factory version. We must have respect for the designer of this circuit, because he used some very innovative methods in his design. I look at the meter circuit, and I see a transistor used for a meter protection to prevent it from burning up in case it finds a very strong signal that is too much for the meter movement. And I see how he used diodes to form temperature compensation at the audio amplifier. Very few treasure hobbyists will design these things into their circuits. Yet these are the important things when we are treasure hunting and we find temperatures fluctuating from hot sun to freezing winter times. And what circuit protection do hobbyists use when the "Phenomenon" becomes so strong that it will damage the electronics? None... The engineer had these all these things in mind when he designed this circuit. I will begin work on trying to devise circuit boards similar to the same layout for the components that the original factory model has. This will take some time. But it will be good to wait, because we will need to see if any more errors in the schematic can be found before we have a circuit board ready. Assuming there are no errors in the schematic, it can be used for point-to-point wiring if some hobbyists want to begin for an early start. I know kahyal will be anxious to begin construction, now that he has the schematic that he was asking for to show a pd that detectors metals. Best wishes, J_P

Great job JP ! ...
This is a circuit that will detect metals for sure ! (Btw, does it belongs to this forum ?  )Anyway i am sure this is a good schematic to build a working pistol detector. At a later point one could upgrade it with an electrostatic detector connected anywhere on one of the coils and make it a perfect LRL project. (I hope mesy something transfered the right amount to your account) No one can claim anymore " i could not find a complete schematic on the forum" !

Yes it belongs in this forum. We have learned that a radio receiver is an LRL, a static electricity detector is an LRL, a frequency generator is an LRL, a bent wire is an LRL, a pendulum is an LRL, and a stick is an LRL. Everything is an LRL. Why not a well designed antique metal locating LRL? But we must be careful not to attach an electrostatic detector to this LRL. This will make it unsuitable. Remember what kahyal said when I showed him an electrostatic detector project: "...but this project is a electrostatic field detector and not a pd that detectors metals "We know kahyal will be happy with his schematic of a fully working pd that detectors metals, and will begin building it very soon. But others who want a combination of electrostatic and VLF will be able to receive more of the signals that are found with these unshielded loops to complete the gold signal. Of course these experimenters will probably want to pulse their electrostatic section with a frequency generator at ELF such as the frequency of gold or silver to add the final enhancement of signal processing. But these mods are outside of the scope of this project. This will be kept strictly as a perfect unmodified factory design that people can build so they can tune signals that no other commercial locator will detect. Then experimenters can make modifications as they choose after they begin with an authentic PD that detectors metals. Best wishes, J_P
