Hello dear friend, I did not video
The only difference is that it's good to see the image in the box embedded in a frequency meter for better accuracy and function of the frequency display

What do you mean?
The circuit 718 is the same machine with the changes that created the geo-

Hi WM6,

Thank you once again but there's no AL707 schematic on that thread. I searched and read all the threads here in LRL.com regarding AL707 and it dont exist. GoldGun AL718 is the only one I found.

Regards

Geo,I also have the Gold gun Al707 here in Australia.My understanding is that you are looking for a null or low reading.If you are getting very low reading at a site where there is Gold mineral deposit then the Gold Gun appears to me to be working as intended?

Where did you get the Idea that you should be looking for a high reading?

If you don't have an instruction manual please post your address details and I will send
you a photocopy of mine.

Cheers,Swampy.

Yes expensive,about the price of the latest Australian metal Detector the GPZ 7000[Australian $9500.

Of coarse the Australian Detector works and is finding heaps of Gold!

I wonder if anyone has found any large mineral deposits with the latest Gold Gun offering
from Accurate locators?

Do you reckon the theory as explained in the instruction manual is sound? Not many if any
good reports of the old version of the Gold gun ever finding anything?

Cheers,Swampy.

swampy: Geo refers to the background reading, since there must be a high reading to be able to receive a low reading or null, I have gold gun Al707, and when I buy it from California I received here in Mexico high reading background, as 3000 mv . and when there was a null detect the reading low, (the amplifier and the meter must be used separately) but in 2003 I discovered that the ferrite antenna was broken in half, (it sounded something broken inside the white antenna) maybe that increased the reading because it received high frequencies, I returned it to accurate locators, and they put a new one and I no longer receive high reading ,,, maybe I should wind another broken (but pasted or overlapping) ferrite to try to receive frequency of about 50-100 khz, I have no idea how often I received it when it was broken, but the reading was more than three thousand milli-volts.

Well mate if you still have faith in the Gold Gun,probably the best thing you can do is try and find someone in your area with a Gold gun unit and compare his with yours.If his is giving both high and low readings like it should then I would suggest you contact Accurate locators again and tell them they didn't fix yours Properly the first time and explain to them why?

Good luck,let us know how you get on.

Cheers,Swampy.

Because weather these days are not good i decided to "see" my Geo Gun. I have 3..4 years to go out with it because at some frequencies it was oscillates.Maybe problem is at varicaps or at increasing of sensitivity. Also will try to supply it with Li batteries. I think that it is good for big buried objects.

Regards

I did n't find the schematic yet. Maybe is inside the destroyed hard disk, i try to find it so to solve the problem. From what i see i use a TL071 a TLC272 and a LT?? for true RMS reading.
Also there is a 6 position selector switch so to select the right band. I change frequency via varicap.
