I remember when I was a teenager staring at the ad for a Bounty Hunter I.B. Wishing for enough lawns to mow to be able to afford an I.B 300. Now that I cruise through E-bay the I.B. series rarely comes up. I think this can mean people want to hang on to these detectors, or it can mean they weren't that great! If anyone has personnel knowledge on these detectors please share!
