My opinion on the subject of what kind of signals we are detecting with the PD is that for me every buried metal generates as you said NOISE, -----so for me it doesnt have to be a special signal but very simply noise being generated from all kinds of phenomena as you mentioned, ------so long as we have some kind of receiver to receive this noise we can detect long range.....

Hi kahyal,
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...!! http://www.geotech1.com/forums/images/smilies/good.gif

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 :)

be careful, you don't have permit to contempt to Iran.:angry:
your work is great and i am sure you are great man too, and i am sure you don't want to contempt to Iran, so please edit your post as soon as possible !!

you are very good in electronics and schematics,same as Karl NC.Maybe you are Karl ?!...
And you like so much WHITES brand locators,yes,you and Karl the same person,or i´m wrong?
Nice work ;)

I agree with J_P,that Iran is great historical and cultural among the arab countries,but i heard some stories of how your country deal with TH´s,simple and clean,they hang them all !!! and this is very bad,i have nothing against arabs,simple not agree with this law,and China apply the same law to TH´s !!!
In my country we have 400 years of arab ocupation after the year of 711 DC,when the arabs win big battle(Guadalet) against Visigotic worriors,so also the VISIGOTORUM CODEX is someting bad,barbarians simple cut the right hand if people stole something,but arabs allways hanging until this recent days ??? So,what can worse than put the life of a person so low that can die becouse of TH activity,maybe prisons are overload???thats the point i dont like ,if i´m wrong about this law in your coutry,i´m sorry to post this,but thats what i heard about...
Hi Morgan,

Iran is not Arab country,
Regarding hanging person because of TH, in my country Saudi Arabia TH is not allowed but Also is not a crime, I never heard any one jailed because of TH.

Iran is not Arab country, Iran is Persian! The name of Iran (ایران) is the Modern Persian derivative from the Proto-Iranian term Aryānā,, meaning "Land of the Aryans", first attested in Zoroastrianism's Avesta tradition.
The term Ērān is found to refer to Iran in a 3rd century Sassanid inscription, and the Parthian inscription that accompanies it uses the Parthian term "aryān" in reference to Iranians. However historically Iran has been referred to as Persia or similar (La Perse, Persien, Perzië, etc.) by the Western world, mainly due to the writings of Greek historians who called Iran Persis (Περσίς), meaning land of the Persians. In 1935 Rezā Shāh requested that the international community should refer to the country as Iran. Opposition to the name change led to the reversal of the decision, and in 1959 both names were to be used interchangeably. Since the Iranian Revolution in 1979 the official name of the country has been the "Islamic Republic of Iran."
most people that live in Iran are Persian - Azeri( Azerbaijan's turk's) - turkmen's - kurd's and a few Arab's and other people. the language of Iran is farsi but with Arab alphabet.
in Iran TH is not allowed and TH's have 1 or 2 years jail! but not more than this!
if you need more info, i can post more info here.

Thanks for all this information,i see your country as a lot of history and potential treasures.So be careful to not stay this 1 or 2 years in jail.

Hi sakis1,

Thank you for posting your tips to learn about the NMR that you use on your pistol.
I read your all the websites that show images where you say "look at google images for NMR.
I found that all the images showed powerful magnets that are used to create a very strong magnetic field to put unknown samples into so the NMR can be measured.
What I read from the links you showed, the only way to obtain a strong enough magnetic field to detect NMR frequencies requires using a superconducting magnet to make a 12 Tesla or more field field to insert a sample into. Liquid nitrogen and liquid helium are required in order to cool the solenoid coils cold enough to create the superconducting electromagnet so it can reach a large current flow to create this enormous magnetic field.
Of course, the superconducting magnet wire is usually a copper clad niobium-titanium alloy, because ordinary copper wire does not work.
I can see from your google NMR images that a computer is used to make calculations from the MHz data taken from the sensors in the NMR cyrogenic chamber.
The final calculation can identify what element was present from the precession data.
See below for some images I found when I made the google NMR image search as you said.

I had no idea that you have found a way to miniaturize a superconducting solenoid to generate intense magnetic fields strong enough to perform NMR spectrometry.
This is quite a feat.
This magnetic field is only 200,000 times stronger than the earth's natural field, but it should be strong enough to give adequate results for NMR spectroscopy.
It seems even more amazing that you have been able to identify buried samples without placing them into the 12 Tesla superconducting field on your PD first.


What I am wondering are three questions:
1. How do you keep the liquid nitrogen and liquid helium cold long enough for treasure hunting so your superconducting coil can maintain the 12 Tesla field?
2. What power source do you use to drive your superconducting magnet?
3. How did you manage to get buried treasures to precess when they are not first placed inside the 12 Tesla magnet cavity on your PD?

Best wishes, :)
