Thanks getsa , can you share the scheme it seems that it is not the same as nikko10. Greetings

Here is how 2 tones variant should work.

I did two tones Admiral by nikko10 but I don't like how it works. When I switch two tones mode I have to return the thresh-a and I lose depth
My question to nikko10 is this normal? or I made a mistake somewhere? Thanks

[bonchev2]

Yes

Yes it was GB potentiometer and also you can change ends of the coils to see that any difference
Good luck

Hi bonchev2, do you mean change polarity of coils ?

[bonchev2]

Yes it was GB potentiometer and also you can change ends of the coils to see that any difference
Good luck

The device works well for coins but does not detect large non-ferrous metals. When I passed with the big object, a strong signal is indicated on tl072 pin 7 but there is no sound indication at all. Has anyone had a similar problem and if so can it be fixed?

Do you fixed this problem ?

[bonchev2]

You can change frequency by chenging parallel capacitor on TX

thank you so much

I'm not familiar with the Admiral project so I don't know what the intentions were. bonchev2 says TX=1mH & RX=12mH (post 205) which gives a TX frequency of 8500 Hz. In reality, you can use other inductances and adjust the circuit to work at whatever frequency you want. If you haven't done so, read through this entire thread and see what people have done.

hello master carl;
When you examine the circuit, what should the appropriate coil values be?
Kind regards
