I'm curious enough to ask this.--I see the listing of the differences of features etc. in these two detectors, so that's not my question.---My question is: (drum roll please)--you experienced guys that have used the 70 & now had a little time to use the new 705.--What do you see as the most effective (important) changes to improve performance & benefit you that the 705 has over the 70?--I'm talking about increased performance (benefits) in the only area that really matters (when you cut to the chase)---in the field & under actual hunt conditions (although we all agree that hunt conditions can and do vary widely).--But let's say "apples for apples" hunt conditions for you with those two detectors.---To put it another way, do you think it was worth it to you to purchase the 705 (after owning the 70)--and why?----I'm an old Ex/Etrac guy and yes, I do have a Xterra 705 comeing.--Two of them (one for the wife & one for me)-we think they are really neat little detectors.---I'm not EVER giveing up my Etrac though! You guys are a neat bunch over here on this forum!------Take care, Del
