I recently received an XLT Series E in a trade and was wondering whether I should hang onto it or use it toward trading for a Tesoro Cortes. I haven't used a Whites detector in sometime and really wasn't looking for one when along came this XLT. I like the display on the detector and it seems to have a lot of programming adjustments that can be made for a variety of hunting conditions. But how does it measure up? Will the XLT out perform the Cortes. I've never had the opportunity to use or even see a cortes in action, so I have no firsthand experience with it's capabilities. So what do you think?
