I agree with Bryce about all the Explorers being good machines. I have an XS and an Etrac (looks like, but isn't an Explorer, but still Minelab). Really like them both, and won't part with either. I've had the XS for 8-9 years and the Etrac 1 year. (Had to have a new toy) My hunting partners use Minelabs. One and ExII the other an XS. The XS user and I have had them about the same amount of time, The ExII user a couple of years less. We all do very well on our finds, but my XS partner and myself usually battle each other to see who comes out on top for the month in the silver count. I know there are a lot of variables here: experience, knowledge of machine, number of times out, and just plain ole "lucky enough to walk over a target". etc. He doesn't change settings on his machine and still uses the stock 10" coil. After 8-9 years, this equates to him knowing what his machine is telling him. (He is also primarily hunting silver, and doesn't have the machine opened up as much as the other two of us do). I never used an ExII or an SE, so can't personally comment on them. Between my XS and Etrac, strictly for ME, I would probably go with the Etrac over the XS, based on things I've recovered with that particular machine in the first year of use. DON"T read anything into that, because I am NOT trying to start an argument between which machine is best!!!!!!!!! I found a lot of nice silver and misc other things with the XS in the 8-9 years as my primary machine. I have found some really nice things in the year with the new machine. Both machines are good for nickels (for you nickel hunters), for me the etrac has more fine tune ability and I find more nickels with it. This month I have a, dated (1867, 1883, 1936. 1971) Grand Slam on the 4 styles of US 5-cent pieces. A first (and probably the last) time for this. Judging from the replies, I would say that whichever machine an individual thinks is best, is based on their finds and how comfortable they are using a particular model. They know the responses and after hours of use, what a target "may" be. There are always surprises in those finds: in 2008 I was using my XS in an old area that used to have a college building on it, but is used for overflow parking for ball games now days. I wasn't having a good day, and got a 26 signal. I thought another zinc penny, but decided to dig it anyway. I dug about 4-5 " and in the hole was a Buffalo nickel, a Barber half, and a bent rusty nail, and NO zinc penny....I still don't know why I got a 26 reading....anyway there is probably no definite answer to the original question...One tends to blame the machine when they aren't being very successful with it....but as the old saying goes "the equipment is only as good as the operator". Whichever machine you chose will be a good choice.
