hi to all, left and right antenna are both connected . The middle antenna is ground. In a few hours i ll send you some new fotos from pcb...

In my vesrion the center antenna emit the waveform and the others left/right is connected too with resistor to mc.
The right and left antenna in oscilloscope shows sine waveform same freq

If you want to actually detect gold in its natural setting, the best frequency is 19.2 kHz. But frequencies all the way from about 4 to 100 kHz have been used, and 71 kHz is a popular frequency with quite a few folks. So is 13 kHz.

I'm not speculating. Anyone who is well informed on the subject of gold detection can tell you the same thing.

The problem is not how to locate gold (and at who frequency) but how to reject the old rusted steels. The basic problem at my country....

I think that after the raining it is time for......
What you say??????

Regards

i think is a good time .....!

here is some waveforms when the detector are set to gold.
For general propose because as we have said is for rubbish.
The center antenna and the right the same is the left
I have make mistake for the freq and for the waveform this is the correct

hi to all, i send you some fotos , no good quality , but you can see how is the circuit....
By the way I ll try many times to use it in all over Greece , with different weather , Different season and so on... after a lot of trials i give up... I think you loose your time to try to fix it or upgrade it ! Propably you must look for another locator... this one is nothing...
I can write a book with fail signals all these years
this all from me
bye

Thanks for photos

hi petros047

hi . how are you?
your information is good.
i want to make a LRL detector, can you send me part list and quality photo from back and forward circuit?
thanks a lot

hello
i want to made your LRL detector, can you put part list and quality photo from back and forward circuit?
is that chip Attiny2313?

thanks man
