Hi Tom,
Since buying Jim's Mark 1, I've grown to love the machine
Since it can discriminate up to and even knock out the silver dollars, It would seem to be a great cache hunter. I'm going to bury a jar of coins at different depth levels and scan the cache with the Mark 1 fitted with a 10" coil using high discrimination knocking out trash and coins up to the silver dollar size. Hoping the machine will detect that cache of coins and bypass the smaller high conductors that sound like a deep cache hoard.
May be interesting to see the outcome of the results, This unit may be a cache searching machine too
