Garmin DESCENT MK3 Series User Manual

Sensor Type Description
Tempe
You can attach the tempe temperature sensor to a secure strap or loop where it is exposed to
ambient air, so it provides a consistent source of accurate temperature data.
Trolling Motor
You can use your device as a remote control for your Garmin trolling motor (Pairing Your
Watch and Trolling Motor, page47).
Vectronix You can use Vectronix
®
rangefinders, and view additional ballistics information on your watch.
VIRB
The VIRB remote function allows you to control your VIRB action camera using your watch
(VIRB Remote, page123).
XERO Laser
Locations
You can view and share laser location information from a Xero device (Xero Laser Location
Settings, page124).
Pairing Your Wireless Sensors
Before you can pair, you must put on the heart rate monitor or install the sensor.
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.
NOTE: The Descent transceivers can be paired through the dive setup menu (Pairing the Transceiver with a
Descent Watch, page9).
1 Bring the watch within 3m (10ft.) of the sensor.
NOTE: Stay 10m (33ft.) away from other wireless sensors while pairing.
2 Hold MENU.
3 Select Sensors & Accessories > Add New.
TIP: When you start an activity with the Auto Discover option enabled, the watch automatically searches for
nearby sensors and asks if you want to pair them.
4 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60).
HRM-Pro Running Pace and Distance
The HRM-Pro series accessory calculates your running pace and distance based on your user profile and the
motion measured by the sensor on every stride. The heart rate monitor provides running pace and distance
when GPS is not available, such as during treadmill running. You can view your running pace and distance on
your compatible Descent watch when connected using ANT+ technology. You can also view it on compatible
third-party training apps when connected using Bluetooth technology.
The pace and distance accuracy improves with calibration.
Automatic calibration: The default setting for your watch is Auto Calibrate. The HRM-Pro series accessory
calibrates each time you run outside with it connected to your compatible Descent watch.
NOTE: Automatic calibration does not work for indoor, trail, or ultra run activity profiles (Tips for Recording
Running Pace and Distance, page121).
Manual calibration: You can select Calibrate & Save after a treadmill run with your connected HRM-Pro series
accessory (Calibrating the Treadmill Distance, page34).
