Got out for the first time in a month or so (too hot and dry and all my fields are planted) went to a spot about 50x50 that me and Rusthunter has hit several times. I got a good but a bit scratchy tone of something good or as many times we hunted hear probably a big chunk of shallow rusted iron which I thought it was dug or should I say chip down about 3in and sure enough there was my rusted chunk of iron >:# but as I always do rescanned the hole and a nice clear tone and dug down another inch and popped out a 1857 LC I honestly do not know how it picked it up the iron was or almost covered the size of the hole was it just luck or do I give credit to the detector I also picked up my 5th or 6th fat IH a 1860 with this detector this thing just LOVES copper!!
