This was a weird find today. It actually didn't register on my DFX but I found it with my pinpointer while looking for a small target. There were several pieces of trash above and around this piece so I guess they could have masked the signal. When I laid it on the ground and ran my detector over it the thing liked to have blown my headphones off my noggin! Anyway, it is about 16"s long and 2"s in diameter and is very heavy. I was told by one of my friends that it may be an old railroad car connector pin.
