I was in a pawn shop and saw this Ace 350. I have a Whites Coinmaster pro But always wanted to try a Garrett, So I went home and got all the gold I had found and went back to the Pawn shop and traded my Gold for this Garrett Ace 350. Worst decision I EVER made. I took it out and all I got was one way signals or the thing would just ding and nothing would be there. I sent it into Garrett, they sent it back saying Nothing was wrong with it. I even got a small sniper coil thinking that would help, WRONG!!!! OH I get lucky every now and again and find a coin about on the surface but NO COINS below ground everything deep is JUNK. I wouldn't recommend the Ace 350 to anyone. I would like to try the AT PRO or AT GOLD, But after my experience with this ACE 350 I am a little hesitant.
