Went back to my iron loaded foundation site again. This time turned sensitivity down to 3 & went slow and kept sweeping from all different angles. Any "fringe" type signal, or iffy sounds I dug. I brought a bucket to put iron crap in. Well, there's nothing great in my hand, but again I was told it was "hunted out" & I was wasting my time Plus, any of these 4 flat buttons could have been an 1812 or something dandy. I also was able to pull up a couple musketballs, colonial copper (bent), shoe buckle piece, and a kinda cool "mini sword" thingy that should probably go to the "whats-it" boyz....HH, Bill
