I have permission to hunt a 40,s house and I am cleaning up the surface 6" with the gold bug I got a signal and found a old cone top beer can about 5" deep and it was coming out in bits and pieces, I was using the magnet to get all the bits , or Iron you can see in the picture how the stick to the magnet I keept re scaning the hole after sweeping it with the magnet still getting a signal but nothing sticking to the magnet so i switched to disq , and a nice high tone comes thru well out came a nice brass thing you can see it obove the LIFTIME logo this is why i dig all metal to uncover masked Items and that brass think could have been a silver coin , so I will keep this up on this site after the 6" stuff is gone i will get out the blisstool and go for the deep things ,
