help me mod my long range compass
I have a long range compass detector with 3 antennas.
I have analyze freq in oscilloscope and the output is about 110khz to 170khz,
I would like to make it more sensitive and to mod the freq for gold.
Do you have any idea how to begin?
Some friend told me that have mod the antennas and let only one on detector probably the receive antenna and the transmit antenna rewire it and have it in his hand and it have good results.
I didn't see that myself and I don't know if it work for real.

I am not familiar with it, can you send a picture, instruction manual etc?

I have a tuning hammer for your long range compass detector with 3 antennas. Send me $49.95, and I'll get it right out to you. Three good whacks, and your long range compass detector with 3 antennas will give you just as good a chance of finding something with as you have now..

ok here is some images.
as i can see the logic board didnt have any power rf transistor or any rf circuit.
Is only the microcontroller.
This detector it is not mine i didnt buy it but it come to me to make some test and if I can to make it better.

Seriously Petros, it is garbage. Try and make a portable radio out of it if you can.

This is a good option and probably the other men do the same it make a second one to work with two.

Still dont understand what the 2 antennas left and right do.
In some schematics who I found in the web the center antenna is the emiter and the other two go to ground here is different.

Petros, that thing is a dowsing rod scam. It doesn't matter what the antennas are doing or what frequencies are used or anything else, it's a dead dog from the start and there is absolutely nothing you can do to make it work.

I deal in reality
I don't see anything on that board that vaguely resembles a transmitter circuit. You say you can send it back? Do it ! Frank
