I read a review that stated the E-Trac was better than the LTD for anyone west of the Rockies. I'm in No CA and am trying to decide on a new MD,,, E-Trac, CZ-3D, LTD. All of them are pricey and I want to know I'm getting the best for my area. I love silver and jewelry (don't we all!!) But will dig relics at an old site. So many MD's to choose from,,,,,,
