I was wanting to get some feed back about the Pro from people who use them. I currently hunt with the Mxt and have a Fisher GB as a back up. I"m selling the fisher and the AT Pro has caught my attention. How are they for relic hunting? Coin's, what kind of depth? And I'm looking forward to trying some water hunting.How are they in heavy iron? I appreciate any answer's you guys can give me on this machine. Thanks. Pat
