Ask for help Surf P.I1.2
Hello.
I'm from the Czech Republic, I set up a Surf 1.2 detector that does not work very well.
It does not have a good depth range (tried several coils, and still the same). Another problem is that when approaching the metal (about 3cm) the signal is interrupted instead of being the strongest. All measurements on the integrated circuits are managed, set to 0V
on NE5534P. I have original circuit board from Ebay, so it should not be a mistake. Maybe R18 and R20co I have read to be opposite. I do not know what can you please help somebody? Thank you very much. I speak English, it is translated from Goglu.
