Understanding Barometric Altimeter Watch Modes on Outdoor Watches

The barometric altimeter on the Outdoor watches use barometric pressure to determine changes in elevation as well as changes to the pressure caused by weather patterns. Garmin outdoor watches will continually monitor barometric pressure to determine which mode is most appropriate at any given time. 

Barometer Watch Mode

• Auto (default setting) - The watch will monitor changes and automatically switch between altimeter or barometer modes
• Altimeter - The watch is locked in altimeter mode and all changes in pressure will impact the elevation reading. This mode is best for activities with a lot of elevation changes. 
• Barometer - The watch is locked in barometer mode and all changes in pressure will be considered due to weather and changes in ambient pressure. This mode is best used for activities without a lot of elevation changes. 

For information on manually calibrating your altimeter review your Garmin owner's manual. null
