Has anybody used the AT PRO for relic hunting? What kind of depth are you getting with it? Since my Compass bit the dust I have been relic hunting with a Garrett ACE 250 until I can decide on a new machine. It has been doing better than I expected but it doesn't have the depth. The relics around here are pretty deep,6 to 7 inches at the very minimum. The AT PRO is all you read about on the Garrett forums but I haven't seen any treads on it's depth. I think most people are using for coin shooting and I am just wondering if it's not just a supped ACE 250. Any info on this machine would be appreciated...........Bill in NC
