Finally able to try it out, just in the back yard with the kids. Just used pattern 1 with sen around 20, was real stable. Recovered 2 keys, 4 pennies not sure what year yet haven't cleaned them, couple pieces of scrap and of course 1 pull tab. Not to bad for 30 min. I've hit the yard pretty good over the year with my other units and our home is not that old. Next outing plan on recording the target I.D numbers for better reference and switching between patterns and all metal.Really like this detector. Derek
