Ascending a mountain peak? Making a boardroom speech? Either/Or There's never a need to remove your Suunto Core. The Suunto Core epitomizes the latest advances in the Suunto aesthetic, coming in a stunning array of colors and configurations - from basic yellow-on-black to lustrous steel-on-steel.

• Altimeter : Accurate to 30,000 feet, displays current elevation, shows elevation gain/loss, and records your entire session for later analysis. Simplifying altimeter use, the Suunto Lumi 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.
• Barometer: Measures and records air pressure to help you predict changing conditions. Features automatic Alti/Baro mode that senses movement or lack thereof, switching between altimeter and barometer accordingly. Weather Trend Indicator shows 3-6 hour barometric history.
• Storm Alarm: Activated by a rapid drop in air pressure over a three-hour period, the Storm Alarm sounds and flashes, letting you know that something unpleasant is fast approaching.
• Compass: Digital compass keeps track of direction. Bearing lock with traditional rotating bezel or adjustable digital lock.
• Sunrise / Sunset: Just set your continent, region and city, and you'll always know how much daylight remains for safe climbing, skiing and off-trail travel.
• Snorkeling: Head into the surf and the Suunto Core shifts from air to water pressure, providing accurate depth readings to 30 feet.
