Couldn't get much out of it, and I've never heard of anyone else who has had success with one. Still, I'd like to get mine into an area where there's more natural gold, and see what it does. Based on what I know of Accurate Locators, I don't expect much of it.

nice schematic... but how can this "thing" find e.g. gold ???

For me it can't does that.

What I understand of this circuit is that there are two opposite wounds on ferrite rods... like one would see e..g. in a gradiometer but with magnetic hi-perm. core, then a "filter" or "decoupler", then amplifier, then another decoupler and another amplifier !

Does it find gold ?

For me if another "version" of "anomaly detector": this is magnetic , where zahori is electrostatic.

That's so, zahori react to E-field and E-compoent of EM radiations, this react to local B spot variations or B-component of EM radiations.

If you use it near a power line you'll see the ufo ! Like with zahori.

You probably have to use it from E-W direction cause N-S movements will pick variation of coupled Earth magnetic field.

Unit is probably subject to ULF/ELF (if present) detection... e.g. low frequency modulation of 50/60Hz , ULF due to navy subarine comm. emissions, ULF due to atmosperics phenomenon etc etc etc

But then ? Is it an advantage for you ? Don't understand.

Any big spot variation of Earth magnetic field will be detected by movements of rods axis near the hi-gradient area, but can you pinpoint anything that way ?

How can it just pick few pT variations due to gold and not nT ones due to e.g. big iron stuff in ground ?

For me cannot find gold, just gold or precious metals, but will find any power line, any railway emission, any huge scrap of iron, any lightening etc etc

Nice schematic, yes, have a differential fet configuration, hi-impedance...
but for me is just another zahori that serve nothing.

Best regards,

Hello:

Yes the model 707 have only one rod ferrite 1/2 inch, the other model 718 two ferrite.
The ferrite is difficult to find, I buy one in company, California, U.S.A.
and in the stormwise.com are other, 1/2 x 12 inch.

I experiment with diferent ferrites, small, etc, and with small rod I listen Am radio, the gun is a simple receiver? or what.

yes I know is better work with low freq. this penetrate better in ground.
and I think build a transmitter to gun, the company say GG work 7.5 khz.

some day put in my yard, detector Garret and I receive the signal 20 meters away....
