The altimeter features a range up to 9000m (29 500 ft). It is ideally suited for all activities where knowing your altitude and ascent and descent rates is essential. The Core altimeter sports an altitude difference measurement that allows you to track your progress in terms of altitude climbed. The log recorder stores all your movements in altitude between the start and stop times, so you can re-live your trip at home - view graphs of changes in altitude during your treks, find out how much you climbed, the duration of ascents and descents, average ascent and descent speed and more.
Suunto Core displays the current sea level pressure as a detailed graph, showing recording of the last 24 hours with a recording interval of 30 minutes. The weather trend indicator is a useful feature providing quick reference to check upcoming weather conditions. The storm alarm notifies you of a sudden drop in air pressure, which may be related to worsening weather conditions.
Automatic Alti/Baro switch
Suunto Core sports an Automatic Alti/Baro switch, a smart feature that senses your movement or lack thereof, switching between altimeter and barometer accordingly. When you're climbing, it records changes in elevation. And when you stop to rest, it records changes in barometric pressure. A drop in air pressure while you're sleeping under the stars will be recorded for what it really is: a change in barometric pressure, not altitude
The digital compass displays the cardinal or half-cardinal point and the North. The declination adjustment function allows you to correct the difference between the true North and magnetic North. You can also set it to track a certain bearing, which helps you follow a chosen direction in the terrain.
The compass features a rotating bezel for traditional use (most variants), or a one-touch function that allows you to sight lock and follow a bearing.
Intended for snorkeling, the Suunto Core depth meter provides information on current depth and the maximum depth reached during your snorkeling dive. The maximum depth of the device is 10m (32,8 ft).
Watch functions include time, dual time, date, alarm, sports chronograph, countdown timer and predicted times for sunrise and sunset for over 400 locations worldwide.
