Intelegent Barometer the Suunto Core cover altitude and barometric pressure

An altimeter measures air pressure to determine altitude, while a barometer measures air pressure to determine changes in weather conditions. If you leave your wristop in altimeter mode while hanging out at camp, an incoming low-pressure front (usually associated with bad weather) will read as a gain in altitude, not an approaching storm. Thus, it’s important to choose the right mode for your activity: With the suunto Core use altimeter for activities like climbing, and switch to barometer while, for example, hanging out at camp. The latest Suunto ABC wristops (for example Suunto Core and Lumi) include an automatic alti-baro profile that senses movement or lack thereof, switching between altimeter and barometer accordingly. Therefore when you’re climbing, it records changes of air pressure as changes in elevation. And when you stop to rest, it records changes of air pressure as changes in weather conditions.
