x 11ty on the eTrex 20. I have one that I originally got for enduro motorcycle riding in the mountains of CO. It has a dedicated geocaching function on it although I don't use it for some reason. Get the etrex 20 and a set of rechargeable batteries and car cord for it. I love mine! Also, they've really dropped in price since I got mine 2 years ago. $130 for a refurbed unit and $170 for a brand new one.
