I've been playing with a PI machine, and it DOES pull up targets that are a bit different than when using a vlf machine! Got these the other day, and there were clad coins in the pile... I think my kid snagged the quarters. Oh well...
Man your giving the garret a work out, wait till you get it in the water in a sand swimming area. i found several silver rings with it and 1 kids 14 kt gold, a pile of clad (lots of cans). I even brought up fish hooks from probaly 12 inches or so.
Nice finds
