I buried a clad quarter in my yard at 12". There is little mineralization or EMI. Thought I'd try all three of my machines (see below). Each one was maxed out to the best of my ability, and each had the standard coil (Deus with 11"). Standard programs as well as custom were all tried as was pinpointing. All frequencies were tried for the two machines that have a choice.
Results:
V3i.................intermittent weak beep, no VDI, no bars. Prob would not have noticed during hunting.
CTX 3030.....Target circle in the right place, no VDI, no sound, no red build-up at all. Would not have noticed during hunting.
Deus.............Weak hits on Goldfield and my custom program. If you were going slow you MIGHT have stopped to check them out, especially Goldfield.
Just my yard, my conditions, my settings, my skill. Your mileage may vary.
