it is digitally controlled oscillator . commercial trick !!!!!!
also with variable amplitude . there are some other circuits seem it. i did try lords with oscillator ... didn't work as a long range .

My dear friend, I have worked with many detector circuits, but I believe the Black Hunter was one of those long-range detectors that I was able to get good results from. I tried it on 5 unannounced buried targets and 4 points were good It revealed easily. In my opinion, Blackhunter is a different device than a digital oscillator and it can be used well for an exploration.I've reverse engineered a lot of circuits but none were resin sealed as hard as the Black Hunter.If I can reverse engineer the Blackhunter amplifier circuits, I will definitely share the information in this thread Of course, with this amount of resin, it is a little far from the antar.

was interesting ... are you did measure output frequency and amplitude for silver and gold ?
what was shape of wave ?

The interesting point of this device was not using output with fixed waveform and fixed amplitude.At first, it started with a square waveform, and in the time intervals between the beginning of Grand Balance and the end of Grand Balance, the waveform and the amplitude were constantly changing .The shape of the waves changed from a square to a sinusoid, then to a triangle, and then to the first square symmetry state.The frequencies were very different from the frequencies listed in the booklet, and only the start signal was the same as the one listed in the booklet.In the output part of the antenna, 4 inductors were used in the form of a Wheatstone bridge circuit.There is a very complex logic behind the operation of this device that I have not yet been able to understand.By connecting the antenna, the output power of the detector increases in a strange way
If I can get new information I will be sure to share

Yes, those four inductors like on Bob Fitzgerald?s locators are strange. It appears to me when there is a spike of output from the antenna the inductors grab some of it and feed it back into the system.

I really don't know my friend. The logic of using these selfies is really strange.But it works well in revealing

i have been reading the forum since a long time ago i think it is time for me to buy one to reverse engineer it

Dear friend, I have been reverse engineering the Black Hunter for 2 weeks, but I could not access the main boards and the microprocessor program in any way.I don't recommend it because buying it for reverse engineering is a waste of money.If I get any information about this product, I will definitely share it here
