That's a configurable setting. You can use it as a "pure barometric altimeter" if you really want. Personally I have the Oregon 550 and frequently use both the altimeter and compass (not for mapping though). Both can be disabled if you really want to save battery life, but even with both on, you typically get 10 hours from a set of rechargeables.
