I discovered some guns from the 2nd world war once from about 50 meters and some other time it was 5 or 6 bullets spread close to each other but only 15cm deep.I was surprised to see that it was easy to go on target.
The gold gun has a digital voltmeter giving different readings as you sweep it from side to side apart from the amplified audio signal in the speaker.
I didn't use it many times to say the truth but I could tell whith the experience I had those days that this pistol could detect something.
This is how and why I got my goldgun later on from a shop that was closing down in States.I bought it for much less money than what Accurate Locators used to sell it.
I discovered later on that probably this type of lrl doesn't work any more since most of the VLF stations arround Greece closed down.
Some other users here in Greece say that there are some emmisions in certain days but thats not a solution for me.
Even accurate locators made a Tx later and started selling it again until it was for some reason discontinued.
So I am in position now looking for a Tx to duplicate the emf fields of the old days that don't exist now.
But the truth is I always leave it behind J_P because I can not reach to a right conclusion of what is best to do.
I can put photos down of the cct or the pistol itself but I think somebody put some already in the forum under some other thread.

Hi g-sani,
The way you describe the performance of the gold gun sounds similar to a radio direction finder. It sounds like it works by tuning the VLF signal from a distant transmitter that is no longer transmitting. How it can detect buried guns, I don't know. But if it needs a VLF signal to work, then this would explain why there were VLF transmitters manufactured to make a new VLF transmission after the VLF transmitter was shut down.
From what you posted, I would think you first need to determine what frequency the gold gun is tuned to (I think I remember it is somewhere around 60KHz). You may be able to send an email to the company that sold the transmitters, and ask what frequency they are. Then you could build a transmitter that sends a VLF signal at this frequency to put near your treasure hunting area. I think WM6 can give some good information on how to do this.
Best wishes,
