I gotta ask this question cause its been in my mind ever since this thing came out. Why would you use that as your main detector if you already have a discriminating detector? I saw this one video where a guy was using that thing as his primary while his Excalibur hung out lifeless by his side, of course he found nothing. I'm sure it's a great pin-pointer in the standard non coil mode, i just don't get why anyone would use it as a stand alone detector for under water hunting where your going to run into all sorts of junk.
