I have been hunting with an EXP_ll for about two years now and thinking about "upgrading"to an SE or E-track. I do love my EXPll and have no complaints. I rarely use any kind of program when I'm hunting and prefer to just listen to it all and have become very comfortable that way. From what I can see all the Minelab machines are basically the same and differ mostly in what bells and whistles they have. I guess that's my question, do the newer units have anything better than my EXPll ? Is a newer unit faster or deeper or better in some way? I have not had the opportunity to try out either of these two machines, wish I could. As I said, I usually don't use the bells and whistles stuff, beyond that, are the newer minelabs better ? I would appreciate any comments from anyone, especially those that have used the newer minelabs. Thanks in advance.
