We went to a yard that I have pounded in the past with every one of my other machines.. every time I go I find something, but lately it wasn't producing. My first target was a modern dime at 5 inches. It was right next to some trash but I could still hear it. That impressed me.. why wasn't it dug before? I moved on and got a 1c-10c id at 7/8 inches. I thought probably just a wheat. Boy was I excited to see this dude!!!
