Hello my friends
I'm interested in the metal detector system tr. But I could not find a suitable power system for the purpose of disclosing large well depth 3 m
Please, if you is possible to identify a circuit I t / r good with good power. Varna and circuit except tm 808. Because I built this circuit, but their detection range is too short.
Please solve my problem help
With respect
