My old faithful AT-Pro died on me today in the water. Tried new batteries but no dice. I didn't miss a beat though...grabbed my backup AT-Pro and hit the water again. I had to send old faithful in early last year for repair and Garrett took good care of me so I know they will do the same again. So glad I have another for backup...love that machine. Old faithful found enough gold last year to more then pay for both machines. Gotta love the AT-Pro...effective and affordable.
