Altimeter: Accurate to 30,000 feet, diplays you current elevation, shows elevation gain/loss, and records your entire session for later analysis. Simplifying altimeter use, the Suunto Core includes a unique start-from-zero function that eliminates the need for entering a reference altitude. With the single push of a button, the altimeter will begin tracking your ascent and descent.
