I would have gotten lost on the tundra if I had relied
solely on my GPS E-compass; I found it was off
anywhere from 5-15 degrees. Also you have to keep
them calibrated. Using Garmin Etrex vista (original)
the batteries were good for around 4-5 hours of
continuous use. The battery life depends alot on how
easilyit gets signals(much like a cell phone). I
considered the GPS as my alternate map as well, mine
won't hold them all, oh well. If you are going to use
a GPS extensively I would spring for the one with
largest screen possible, the maps are hard to use on
my vista. I was constantly having to zoom-in and out.
And fiinally the barometer feature is pretty
standard, but if you pay close attention to it you can
really learn the weather. I had a friend who used to
be able to predict thunderstorms 2hr before they
arrived. Good luck I hope this answered your Q's
