Got out for the second time with my new AT Pro today. Hunted an old iron infested site that I have hit over and over with two top of the line detectors. Well they're not much to look at, but I sure was pleased with the way the AT Pro separated these items from the iron. For those interested, I ran Pro Zero wide open with no iron discrimination, and sensitivity at 7 bars. My oldest coin, a 1783 1/2 reale, came from this site. Needless to say, I'll be hitting this site several times with the AT Pro.
