Just had a quick question... Friend of mine purchased a Explorer XS used last summer. We were just talking and he is not happy with it. Would there be any reason for this? He can't keep up with me and the 5-6 times we were out he didn't manage any good targets. I own a couple Garrett's(1350 and 2500). I have years with both of them. I have no knowledge as far as learning curve with this machine. Do you think he should take a step down or should I push him to keep testing and learning the machine??? Todd
