Sensor
Source
Pressure Altitude reflects changes in ambient pressure.
GPS
Altitude is equal to the GPS altitude when GPS is available. Altitude defaults to the pressure altimeter when
GPS is unavailable.
Altimeter Settings
Hold MENU, and select Sensors & Accessories >
Altimeter.
Barometer: Allows you to set the barometric pressure
manually, or select a value from the nearest METAR
station through the Garmin Connect app. Setting the
current barometric pressure manually can help to
improve the accuracy of the pressure altitude reading.
Altitude Alert: Sets an alarm to vibrate when you reach a
specified altitude. The altitude alert is not available in
watch mode.
Sync to Elevation: Allows you to synchronize the watch to
your current elevation manually.
Set Standard Baro: Allows you to set the standard
barometric pressure.
Calibrating the Barometric Altimeter
Your watch was already calibrated at the factory, and
the watch uses automatic calibration at your GPS
starting point by default. You can manually calibrate the
barometric altimeter if you know the correct elevation.
1 Hold MENU.
2 Select Sensors & Accessories > Elevation > Calibrate.
3 Select an option:
• To enter the current elevation manually, select Enter
Manually.
• To enter the current elevation from the digital
elevation model, select Use DEM.
• To enter the current elevation from your GPS
location, select Use GPS.
Barometer Settings
From the barometer glance, press START, and select

Calibrate: Allows you to manually calibrate the barometer
sensor.
Plot: Sets the time scale for the chart in the barometer
glance.
Storm Alert: Sets the rate of barometric pressure change
that triggers a storm alert.
Sensor Mode: Sets the mode for the sensor. The
Auto option uses both the altimeter and barometer
according to your movement. You can use the Altimeter
Only option when your activity involves changes in
altitude, or the Barometer Only option when your
activity does not involve changes in altitude.
Pressure: Sets how the watch displays pressure data.
Calibrating the Barometer
Your watch was already calibrated at the factory, and the
watch uses automatic calibration at your GPS starting
point by default. You can manually calibrate the barometer
if you know the correct elevation or the correct sea level
pressure.
1 From the watch face, press UP or DOWN to view the
barometer glance.
2 Press START to open the glance.
3 Press START to view the settings menu.
4 Select Settings > Calibrate.
5 Select an option:
• To enter the current elevation and sea level pressure
(optional), select Enter Manually.
• To calibrate automatically from the digital elevation
model, select Use DEM.
• To calibrate automatically from your GPS starting
point, select Use GPS.
Elevation Settings
Hold MENU, and select Sensors & Accessories >
Elevation.
Calibrate: Allows you to calibrate the altimeter sensor
manually.
Elevation: Sets the units of measure for elevation.
Wireless Sensors
Your watch can be paired and used with wireless
sensors using ANT+ or Bluetooth technology (
). After the devices are paired,
you can customize the optional data fields (
). If your watch was packaged
with a sensor, they are already paired.
