I am interesting know , what was in practical test result for that engineer?
Is he or she member in geotech?
Best regards.

Hi Aft,
I read these reports some years ago in a forum that is no longer online.
So it is hard for me to remember all details.
From best I can remember, the engineer is also a Geotech member.
He posted photos of his adaptation of this original factory locator to a pistol configuration in the forum that is no longer online.
I saw his photos of the circuit boards with components.
I could read every resistor color code, and see all the capacitors on the board.
This is how I know the circuit is not fake. It is unmodified, exactly as the factory designed it.
He said it was good for detecting most metals whether it is buried a long time or not.
He could also detect small metal things like coins in the air.
But he did not need to wait for the proper atmospheric conditions.
He was detecting on any day even if it is raining.
I try to remember the engineer's screen name from the other forum, but I remember he worked with a lot of electronic circuits,
I think he even helped with the electronic design for some commercial metal detector.
I remember he said he could point this locator in many directions and hear signals arrive which his other detectors did not detect.
But he did not report if he ever followed to find the exact source of the signals.
In fact, shortly after he showed his PD, he stopped making reports about it.
This is why I don't know the true distance that this locator can work.
I also remember he said there is no Faraday shield of any kind used on the coils in this locator.
I think this is important, because a Faraday shield can block much of the electric field component of incoming signals.
It will be good to hear from others who have experience with this design kept as the original factory circuit to see what distance they find.
I will try to find some of the original operating instructions for this locator.
Best wishes,
