I thought they didn't make the 12 any more. I bought an Etrex after my 12 went swimming when the bag came open :-( I thought the 12 was more ergonomic; easier to work buttons and get to where you needed to go. I also thought the 12's connector held up better in salt water, AND you could hack a 12V power cord. The Etrex was more accurate and I think it lasts longer on two batts than my 12 did on 4. The Etrex is just a little too small for the boat; hard to hold and hard to see.
