Help all. I want to buy the best detector for deep targets in the $600 range give or take ahundred. (I'm tired of the Bounty Hunter Quick draw!-it doewsn't seem to get a coin past 4 inches, and its target discrimination in my opinion is not the best. I've read about the Whites Matrix M 6, MXT and Minelab SE? They all sound great. Your input is greatly appreciated.
