Have an AT PRO, and am very impressed. Use the smaller AT GOLD coil, and really like it. I also have a F-70, T2 SE-LTD, Eurotek Pro, -F2 ---Is there a legitimate reason to purchase a GOLD if I do not hunt gold? I usually run the Pro in Pro mode, Zero Disc. I don't have a hard time listening to it like I do some others. Have a NEL sharpshooter on it's way for the AT Pro----. Like it on the F70. I hunt some pretty trashy areas, GB avg. 74 to 90. -- Mainly hunt coins. Any advice would be appreciated. Thanks!
