I picked this up on Ebay as a backup detector and it's given me nothing but problems. As soon as I turn it on and try to use it the thing starts beeping erratically --- think R2-D2 on crystal meth. I read the guide thoroughly, played with different settings and modes in different environments and even sent it to the Bounty Hunter Repairs Dept. They sent it back a few weeks later with a letter saying that they had re-calibrated it (with no positive results). Is there some specific setting on this thing that works best It seems oversensitive & erratic to the point that zeroing in on an ACTUAL target in the ground is impossible. In air tests it consistently identified modern pull tabs as nickels no matter what the setting. I'm about ready to play metal detector baseball with the nearest tree!
Any experienced QD2 users out there...?
