Altimeter and Barometer
The watch contains an internal altimeter and barometer. The watch collects elevation and pressure data
continuously, even in low-power mode. The altimeter displays your approximate elevation based on pressure
changes. The barometer displays environmental pressure data based on the fixed elevation where the altimeter
was most recently calibrated (
).
Sensors and Accessories
The Forerunner watch has several internal sensors, and you can pair additional wireless sensors for your
activities.
Wireless Sensors
Your watch can be paired and used with wireless sensors using ANT+ or Bluetooth technology (
Your Wireless Sensors, page 78
). After the devices are paired, you can customize the optional data fields
(
Customizing the Data Screens, page 105
