I was out detecting today when a couple guys started talking to me. They asked the normal question like are you finding anything. I showed them the 3 ringer I had just found. One of them then asks if a detector would detect metal in someones body. I said sure. One guy held out his arm and he had a spot that looked like a small hole. Said he was hammering and part of the hammer head broke off and went into his arm. I used the pro pointer and sure enough it sounded off on his arm.......Dont know if he plans to get it removed or not......;o)
