I use the T2 SE and I am primarily a coinshooter. It's no slouch in the cool ass relics department to boot. In the last 4 weeks I have pulled over 35 "keeper" coins from areas that I have previously POUNDED with many different detectors (Explorer 2, AT Pro, Omega 8000). I had experience using these machines, but the bottom line is that the T2 SE is a great machine with great depth. I'd say that 80% of the coins were found between 8"-9" and more than half are silver. I just found two LC's (1831 & 1851), and a Seated Liberty Dime (1856) today at a church I have been hitting for a few months. The LC's were roughly around the 11" mark and the Seated was between 9"-10". The trick to this machine is to be PATIENT and learn the tones. The Boost Mode on this machine is what makes it a monster. The Boost mode has KILLER depth. The machine straight out of the box can hit a silver dime at 7"-8" with no problem. I have found that with this machine more sensitivity does not always equal more depth. When dialed in properly this machine will have other coinshooters hating you because you will find EVERYTHING. If you want more of my opinions and experiences with this machine hit me up. I have some great settings for coins and old buttons. Another plus is the fact that it's SUPER light and VERY easy to use.
I also want to add that deeper coins are better than a whisper with the T2 SE. Coins at 8" sound just as loud as coins at 3". The Boost mode on the T2 SE is the balls....
