So I received my M-6 a few days ago and decided to swing around in my yard by my largest oak tree. I have been through this area with at least 10 different machines including the safari, CTX, sovereign, silver uMax etc. I like the way the machine runs in single tone with disc set at 1. I got a solid repeatable tone that pinpointed solidly at 8". It jumped around in the 70's, 80' and down lower on the VDI. When I flipped to tone ID it was not a good signal at all. Well after digging down 6" or so I swept the DX-1 probe in hole and got a solid tone. A couple more scoops and out pops a wheatie! I could not believe my eyes! I know it is only a wheatie but how had I missed it with so many other machines
