Had a small job this morning close to a place I have been trying to get to all winter but the road was impassable, small mining town in the foot hills lots of iron and few targets. I was hunting in TTF stock coil auto +3 sens was about 15 I had been there about four hours and found nothing but trash and the skeleton key (eyeball find)bent down to move a piece of wire that my coil was hanging up on and noticed a strange shape. As I wandered aimlessly I was getting a little frustrated at the lack of any good signals I saw a big bone from a wild horse as I got close I got a 12-37 and thought a zinc penny way out here to my surprise it turned out to be a 1915 S wheat penny (in great shape ) about 4 inches deep. I started working around where I found the penny and a foot away on the other side of a little bush I got a really bad signal. In with the iron signals the ground is very soft and dry, here so I just stick my lesch in the ground all around the spot and loosen it up and dig with my hand.
