I got a faint signal while i was hunting in the woods. I dug down around 4 inches and my pointer kept ringing as I looked through my dirtpile but i could not find the coin. It did keep going off on this little wood chip so I kept it. After i got home and cleaned it off i could still see nothing in it. After it dried out i could see the surprise it held inside. It looks like a little 22 caliber bullet was buried inside it. Nice little surprise indeed.
