Got my At Pro this week and played with it in the yard for a couple of evenings and took it out for a hunt today. I went to a place where an old house had been. The house has been gone since about 1940 and is full of junk. I started not to go there because I had hunted it so many times with 2 other detectors but I wanted to see how the At Pro really did in the iron junk. I have to say it is an amazing machine in iron, the audio is full of information. I was running pro mode zero with disc of 35 and running iron audio, I like to hear it all. I dug a couple of interesting things, a pin with whatever was attached gone but will go back and try to find the stone or whatever was attached later. But then I got a sweet signal amid the iron, solid id in the mid 80's surrounded by iron, I dug down and found 2 nails and a really small piece of metal and thought, is that all! Put my pro pointer back in and there was something else about 5 inches. I could not believe the nice looking button staring right at me. I had no idea what kind it was, being in my part of Oklahoma we don't see all that many military buttons. I thought maybe it was a Calvary button but it is a WW1 great seal military button. Not as old as I first thought but a great find for me non the less. This At Pro is going to be the ticket for hunting in iron infested junk. I like it, this is my first Garrett and it is a keeper.
