I bought a new AT PRO the first part of February this year. Probably have used it 25 hours total. It works just like it's supposed to I guess. But to me it's noisy and hard to pinpoint with. I prefer to use my old Garrett Grand Master Hunter CX III with a 4.5" sniper coil. I can't decide if I should buy a 4.5"sniper coil for the ATP or just give up on it. I really don't think there is anything wrong with the Pro. I'm just kind of thinking it's not the detector for me. Can't decide if I should spend more money on it or not...
