RE: GPS questions
Three years ago I asked around about which was best. A co-worker, who uses his in Colorado, told me he just purchased a low-end Etrex because the one he had (with the mapping) burned through batteries too fast. I also purchased the low-end Etrex (Summit) and love it. Of course, I only use it to mark camp, truck, hunting spots, and tree stands. It has never let me down. It takes a little longer to get bearings in heavy canopy.
Battery life may be better now or with different makes.
