Just more things to go wrong. Not sure why they just don't focus on a detector that just detects well.... actually I do know, because people are crazy enough to pay $1,000 more for unneeded gadgetry and because it's new. People already jumping on board and who's to say it's not X-terra guts in the thing. Fortunately since the Day the Explorer II came out (which was over hyped too for the little extra it had) they have not come up with nothing better so I get to save my money!
