Suunto Core All Black Watch is a lightweight tool for you if your adventures take you way off the beaten path. An altimeter tracks your altitude as you scale mountains and descend into valleys and it records your trip so you can analyze it later. A barometer monitors atmospheric pressure it automatically alerts you when bad weather is approaching if the pressure takes a sudden drop over a three-hour period. A digital compass helps keep you going in the right direction. A depth gauge that measures to 30 feet is great for snorkeling trips in the tropics. Control buttons can be pushed underwater. Other features include a backlit display, stopwatch, countdown timer and a four-language menu, all packed into a watch-sized wrist-top computer.
