I need to search a relatively small piece of land to find small silver and copper coins amongst larger pieces of iron (nails, screws, horseshoes). The easy ones have been picked up already by others. I think there are some more, not necessarily deep. Nobody likes to dig iron, me neither. Someone mentioned a BFO with some 10 - 15 cm coil could get some 10-15 cm depth on a coin sized target and not suffer too much (or at all) from iron masking. A non-motion detector could work better in this area as there is quite some weed. I want to discriminate out as much iron as possible and still get signals from all other metals including "foil".
I have a C.Scope CS1MX, which is quite good, but it is motion-type and the coil is maybe just a little too big to fit in. Tesoro Silver uMax just does not unmask with my favorite SEF 12x10 coil, I yet have to try it with the small 5.75 concentric if it can get any better.
I am considering a non-motion C.Scope with a very small coil - one like asolone. Would a simple BFO work?
