The V3 is yet an 'unproven' machine. It has lots of features, incredible innovation, and is made by one of the best manufacturers in the competitive market, but it hasn't had the field testing experience, yet, the E-Trac has. I own the E-Trac. Use the factory presets and it's no harder to learn than any beep and dig machine. After 100 hours or so you can tweak it, experiemnt with different settings, and you won't have to worry about an upgrade in a year or so. Within the first 6 months of ownership you'll find yourself gradually making small changes to different settings and will see yourself improving your finds. That's not a choice on the cheapy machines. The Minelab Explorer series have a long history of solid hard use with deeper finds than any other machine. Everyone's top of the line machines are good. I am reminded of a Sears marketing program where they labeled similar products, "Good', "Better", and "Best." I think the Explorer group would be with the "Best."
