i have the garmin 60csx. I see the altimeter screen...it shows the elevation.
then, under the "satellites" page, i select menu, and then gps elevation, to get another elevation reading...
what is the difference? specifically, i took the gps on the airplane with me today, and it was cool. all speed readings and gps coordinates were awesome to see during flight. However, the altimeter reading was around 6500 feet for most of the flight. when i looked at the satelling-menu-gps elevation, it was the reading i was expecting, i.e. 38000 feet (or so) during flight.
any ideas/thoughts? maybe i dont know what the altimeter is really used for...????
thanks!
