I mostly hunt using tones for target ID. I like the F5 I'm currently using, but was wondering if anyone here could compare it against the new AT, depth, stability on salt beaches, etc. I like to X the target when pinpointing, does it have fast retune like the Tesoros or the F5, or is it like the Ace machines.. Previuosly owned a Tesoro Golden, not much depth, didn't like the tones freq seperation. Owned a Ace 250 but pinpointing was lousy, poor depth and target accuracy was iffy most times. Thanks
