I have Surfmaster PI board and would need opinion for optimal coil setup for prospecting natural gold. I am thinking quite small diameter and very thin copper wire. The environment is Lapland in Finland where the soil is bit less infected with black sand than what I have heard being elsewhere, like in Australia.
I have made modification to front end, original transistor is gone and faster FET is used. Also frequency, pulse width and r6 flyback shunt resistor are made adjustable for optimal triggering.
Any good ideas?
Thanks,
Markus
