Hi all, Got out yesterday and today for a couple short hunts at a local small church. Yesterday I dug a few wheats and some clad. Today I went back and dug another wheat and a zincoln. I was having a major problem digging nails today. The nails came in as good targets for the most part. I rechecked my holes to make sure they were not masking a good target but nothing. I had one that was a beautifully repeatable signal and read 11-44 12-44 but was nothing but a nail. I had some that would jump from 11,12-40's down to 9- 30's and occasionally in the 20's-40's. I guess I haven't notice nails doing this before(sounding good with good numbers) but maybe I just had a brain fart today. Also there was hardly any threshold today it was nulling alot to the point I thought something was wrong but When I got home in my yard it was normal in non trash environment Any help would be appreciated. Thank you.
