That's odd. Maybe you have some funky soil, because my and the two main guys I always hunt with have never had that problem with ours, except on a rare occassion where it falses on some super bad ground for some odd reason. As said, in ground like that we just turn it on with the tip touching the ground and it auto tunes to not do that. Try that and see if the problem goes away for you. Also, maybe it's a problem with the close frequency of your MXT to it, because I know the M6 my friend had like many have said with the MXT would go nuts when the Pro Pointer was turned on. Perhaps it's cross talking to the Pro Pointer and causing it to do that for you? Far as I know (?) no other machines have the cross talking problem with the Pro Pointer, or at least that I've heard. I know it doesn't bother my GT, nor my friend's Etracs or Explorers. I think I remember reading somewhere that the Pro Pointer and MXT/M6 have very close frequencies, thus the problem, but I don't know if that's what is causing your issue. It'd be interesting to hear what frequency this new Minelab is using and what potential problems it might have with certain machines because of that. If it's a different frequency than the Pro Pointer it might be an attractive option to M6/MXT guys.
