The Suunto Core keeps you informed with an accurate altimeter, barometer, digital thermometer, weather trend indicator and digital compass. The pressure gauge operates in four distinct modes, including an automatic setting that senses your movement or lack thereof, switching between altimeter and barometer accordingly. The compass features a rotating bezel for traditional use, or a one touch function that allows you to sight, lock and follow a bearing. Daily functions include dual time, date, alarm, sports chronograph and predicted times for sunrise and sunset. Essential gear for the vertically inclined! Altimeter Log Graph. Resolution: 1 m.
