I can't believe the depth and target crispness at depth. Great target separation and the concentric coil has no trouble at all identifying the steel bottlecaps that haunt DD coils. I'd put these detectors up against anything on the market right now. Bounty Hunter got it right with these two detectors. Air tests right up there with the F-75 in standard mode and the disc seems to work better. When it warms back up a little I'll try and give some hunt updates but I'm mostly an old coin hunter.
