Hello, I first used a (loaned) Garmin GPSmap 60Cx (without compass and altimeter) and then bought a GPSmap 60CSx (with compass and altimeter). I never use the compass or the altimeter for mapping, but the extra features have a noticeable negative effect on battery life.
So if I had a do over, then I'd buy the one without the compass and altimeter.
