Summary: All you really need in a GPS for the hills. 50 routes gives more than enough flexibility for when you don't really know where you'll end up. The satellite altitude read-out is plenty accurate enough to give you a quick position on a topo map and who really needs an electronic compass anyway? Coupled with mapping software you can't go wrong. Although it looks big compared to the eTrex, it fits perfectly into the LowePro D-Res 20 pouch, which then has space for 8 AA's.
Pros: 50 routes; large(ish) screen; up to 6 concurrent data readouts; ease of use.
Cons: Se cuelga bastante segudo, No tiene mapas completos, estuve en Mendoza y tuve muchos problemas, Me arrepentí de haberlo pagado tan caro., El vendedor me atendió bien pero fue mi culpa el haber comprado mal.
