Mike, (Iron Brigade), I see where you are looking for an Equinox 600. What type of hunting are you looking to use the Equinox for? I'm asking because I relic hunt when I get the chance to go. I have considered the 600 also. I have two good detectors now, A Whites MXT Pro and the Minelab Safari, which I haven't had a chance to use much. I have considered the Equinox for weight and for speed recovery. I'm 64 and my shoulders are beginning to bother me and I believe I may have a torn rotator cuff in my left shoulder. Folks seem to like the Equinoxes and I like the thought of it being light with a quick recovery speed. I just wonder about the internal battery and if it would be too much technology to set up for this old relic hunter. I just thought that we might be able to throw some ideas around back and forth since we are considering the same unit. Good luck to you.
