hit a site that we have pounded over the years and I did find a couple good targets. Came home with 3 flat buttons, a piece of lead, and some kind of tag or plate? First two targets were the flat buttons 1 down about 6" the other 1 down a good 9+ inches. Now the good part!! I got a mid tone with an iron tone mixed in.Mid tone sounded good so I dug it, only down about 3" out come the very small flat button, I scan the hole again and got a iron signal, out came the small nail about an inch under the button!! Nice job by the AT PRO. I'm starting to get a feel for this detector. I just have to get the target number figured out. They are much different than my other ID machine. OH yes, AT PRO is hot on shot gun shells. LOL I got those numbers zeroed in 50 to 60!!! first picture=good finds, second picture =deep button, third pic.=iron and button, last pic= all trash targets dug. Also got to get one of those headphone adapters, I can't set the detector down to dig unless I take the headphones off, cords to short for me and I'll have to extend the arm cuff back. I had to strap the detector to the arm to keep from getting tried.
