Sensor Type Description
VIRB
The VIRB remote function allows you to control your VIRB action camera using your watch
(VIRB Remote, page 80).
XERO Laser
Locations
You can view and share laser location information from a Xero device (Xero Laser Location
Settings, page 82).
Pairing Your Wireless Sensors
The first time you connect a wireless sensor to your watch using ANT+ or Bluetooth technology, you must pair
the watch and sensor. If the sensor has both ANT+ and Bluetooth technology, Garmin recommends that you
pair using ANT+ technology. After they are paired, the watch connects to the sensor automatically when you
start an activity and the sensor is active and within range.
1 If you are pairing a heart rate monitor, put on the heart rate monitor.
The heart rate monitor does not send or receive data until you put it on.
2 Bring the watch within 3 m (10 ft.) of the sensor.
NOTE: Stay 10 m (33 ft.) away from other wireless sensors while pairing.
3 Hold MENU.
4 Select Sensors & Accessories > Add New.
5 Select an option:
• Select Search All Sensors.
• Select your sensor type.
After the sensor is paired with your watch, the sensor status changes from Searching to Connected. Sensor
data appears in the data screen loop or a custom data field. You can customize the optional data fields
(Customizing the Data Screens, page 31).
Running Dynamics
You can use your compatible D2 Mach 1 device paired with the HRM-Pro accessory or other running dynamics
accessory to provide real-time feedback about your running form.
The running dynamics accessory has an accelerometer that measures torso movement in order to calculate six
running metrics.
Cadence: Cadence is the number of steps per minute. It displays the total steps (right and left combined).
Vertical oscillation: Vertical oscillation is your bounce while running. It displays the vertical motion of your
torso, measured in centimeters.
Ground contact time: Ground contact time is the amount of time in each step that you spend on the ground
while running. It is measured in milliseconds.
NOTE: Ground contact time and balance are not available while walking.
Ground contact time balance: Ground contact time balance displays the left/right balance of your ground
contact time while running. It displays a percentage. For example, 53.2 with an arrow pointing left or right.
Stride length: Stride length is the length of your stride from one footfall to the next. It is measured in meters.
Vertical ratio: Vertical ratio is the ratio of vertical oscillation to stride length. It displays a percentage. A lower
number typically indicates better running form.
