I have owned a T2 SE for about 6 months now, and couldn't be more pleased with it's performance. The first day out, I went over my own yard, (that had been detected to death by me and my other machines), dug up a gold plated pocket watch at 11", a sterling silver ring at 12", and two of the old bronze chinese coins at over a foot. (what in the world they are doing in the middle of nowhere in central Utah is beyond me). I immediately purchased the big 15" coil for cache hunting in the all metals mode, (and have had very good luck with it). My only advice, read the manual! I took it out of the box, turned it on, and found a bunch my first day....now that I have read the manual, WOW!
