The Depth Question is always a big one and difficult to answer, I have not dug a target deeper than 9-10 inches with the T2. At these depths the T2 was not straining to tell me there was a target to investigate. The Key ability of the T2 is its extraordinary abilities to pull keepers out of Iron, better than any Detector I have ever used. I have been having a great time re hunting sites and have always gotten a keeper to bring home or two or three. I can not explain in words how this machine differs from others, you just haft to swing one long enough to learn its language, and this is where many have failed with the T2 & F75 - not putting enough time in to learn what it is telling you. No its not noisy, it's giving an accurate analyst of whats really in the ground. My general settings are:
Hum Level set at -2 to -3 / I determine this to a degree of setting the Hum to where it is Quite then switch to Disc Mode. I normally set the Tone at 2+ and when I hunt a really trashy park or school I will switch to Tone 3: Sensitivity as High as I can go in both all metal for pinpointing and Disc mode for Depth and sensitivity to Keepers in Iron. Disc set at 10: Then I will re hunt a site with Disc set at 50 which is the Point of the after burner kicking in or extra gain, still leaving plenty of room for nickels which Disc out at 57. I swing the T2 just like my Sov in heavy Iron and get great results and depth. I have tried to swing briskly in Iron but have not gotten good results, but in cleaner ground I do swing it swiftly. When in heavy Iron trash it helps to confirm a target with a brisk short swing after you located a target to investigate. Another key aspect of the T2 is IDing Nickels next to Iron, it will at times register a nickel under these circumstances in the Low 70's instead of foil or Iron readings. I hope this helps and good Hunting. D Wes.
