I was using the deus xp , the signal was bouncing around a bit I thought it was iron but once I opened the hole it was reading bout 55 to 60. After looking at it closer the hooks on the back are clipped off I think someone did that and nailed it to a fence post or shed that's where the holes came from. After showing my dad he said its the 3rd U.S. buckle to come from our field . Went to another field today found an eagle cuff button and 2 phineals off a cartridge box pretty happy this weekend. I have off all week so hope I can get some more finds to post
