This was a little weird, merc at CO 43 at 5 inches on the E-Trac. Wasn't the best signal either. I think there was iron underneath it as the threshold nulled when rescanning. So, I guess that means ferrous objects in the area can mess with the signal to this degree? This should have been a strong CO 45. I don't remember any nulling when I hit the target initially, so maybe it was directly underneath it? I didn't feel like digging it out to find out lol
The thing is I haven't been digging many 43s at this site, since I'm trying to minimize stress to the grass given the heat and the dryness (and I water each plug when done), so digging targets that don't have much chance of being silver is expensive. So maybe I've missed other silvers by not digging shallowish CO 43s (I dig all the 40+ deep ones). If we get a good rain I'll go back and dig 'em I guess.
