GPS Settings
You can change the GPS settings to customize the satellite systems used for each activity. For more

, select Activities & Apps, select an activity, select the activity settings, and select GPS.
NOTE: These settings are not available for all activities.
Off: Disables satellite systems for the activity.
GPS Only: Enables the GPS satellite system.
All Systems: Enables multiple satellite systems. Using multiple satellite systems together offers increased
performance in challenging environments and faster position acquisition than using GPS only.
All + Multi-Band: Enables multiple satellite systems on multiple frequency bands. Multi-band systems use
multiple frequency bands and allow for more consistent track logs, improved positioning, improved multi-
path errors, and fewer atmospheric errors when using the watch in challenging environments.
Auto Select: Enables the watch to use SatIQ
™
technology to dynamically select the best multi-band system
based on your environment. The Auto Select setting offers the best positioning accuracy while still
prioritizing battery life.
UltraTrac: Records track points and sensor data less frequently. Enabling the UltraTrac feature increases
battery life but decreases the quality of recorded activities. You should use the UltraTrac feature for activities
that demand longer battery life and for which frequent sensor data updates are less important.
Sensors Settings
Compass Settings
Hold
, and select Sensors & Accessories > Compass.
Calibrate: Allows you to manually calibrate the compass sensor (
Calibrating the Compass Manually, page 109
).
Display: Sets the directional heading on the compass to letters, degrees, or milliradians.
North Ref.: Sets the north reference of the compass (
Setting the North Reference, page 110
).
Mode: Sets the compass to use electronic-sensor data only (On), a combination of GPS and electronic-sensor
data when moving (Auto), or GPS data only (Off).
Calibrating the Compass Manually
NOTICE
Calibrate the electronic compass outdoors. To improve heading accuracy, do not stand near objects that
influence magnetic fields, such as vehicles, buildings, and overhead power lines.
Your watch was already calibrated at the factory, and the watch uses automatic calibration by default. If you
experience irregular compass behavior, for example, after moving long distances or after extreme temperature
changes, you can manually calibrate the compass.
