Looks like I need to send in the 705, but wanted to check here first to make sure nonone has a suggestion. It works great in the Prospecting and Disc mode, but when I go into PP mode it acts strangely. It's impossible to PP the target (and I am moving the coil well off the target before going into PP mode) - it just doesn't lock on to where the target is. And, even more alarming, if I stay in PP mode and lift the coil in the air it keeps sounding off like a target is under the coil. Another proble that may be related is that when I go into AM mode to ground balance, it continuously cuts in and out with a VDI of 42 as if there is a quarter in the ground every 3 couple inches. I took off the could cover to make sure I didn't have a quarter stuck in it
, but all was well under there.
