I know it's been said many times before, but I want to say it again, when MD'ing you really need to go slow and low. I was at the Vulture Bait claim last week, NW area, using a Goldbug 2 with a 6" coil and I was amazed on how much small and tiny trash targets I found (over 200). I saw a few folks out there using PI detectors (not sure how they were doing) I know they will go deeper than the GB2 and they will pick up the small gold too. But the amount of small trash targets I found I still believe folks are still MD'ing to fast. I did find my first AZ gold on this claim, two 1 grain pieces and one 8 grain piece, I know the claim has been worked hard but the gold is still there.
