About the Barometric

Altimeter

NOTE: The barometric altimeter does not function in swim mode.

Your Forerunner calculates elevation using the barometric altimeter. The barometric altimeter is sensitive to weather events and pressurized areas such as airplane cabins and cars. If the barometric altimeter starts to report false readings due to environmental conditions, the Forerunner will use GPS elevation data.

You can customize your data fields to include elevation (page 36).

Calibrating the Barometric Altimeter

You can calibrate the barometric altimeter manually using a saved location.
