Heart Rate Features
The Descent device has a wrist-based heart rate monitor and is also compatible with chest heart rate monitors
(sold separately). You can view heart rate data on the heart rate widget. If both wrist-based heart rate and chest
heart rate data are available when you start an activity, your device uses the chest heart rate data.
Wrist-based Heart Rate
Wearing the Device
• Wear the device above your wrist bone.
NOTE: The device should be snug but comfortable. For more accurate heart rate readings, the device should
not move while running or exercising. For pulse oximeter readings, you should remain motionless.
NOTE: While diving, the device should stay in contact with your skin, and it should not bump into other wrist-
worn devices.
NOTE: The optical sensor is located on the back of the device.
• See Tips for Erratic Heart Rate Data, page 53 for more information about wrist-based heart rate.
• See Tips for Erratic Pulse Oximeter Data, page 69 for more information about the pulse oximeter sensor.
• For more information about accuracy, go to garmin.com/ataccuracy.
• For more information about device wear and care, go to www.garmin.com/fitandcare.
Tips for Erratic Heart Rate Data
If the heart rate data is erratic or does not appear, you can try these tips.
• Clean and dry your arm before putting on the device.
• Avoid wearing sunscreen, lotion, and insect repellent under the device.
• Avoid scratching the heart rate sensor on the back of the device.
• Wear the device above your wrist bone. The device should be snug but comfortable.
• Wait until the icon is solid before starting your activity.
• Warm up for 5 to 10 minutes and get a heart rate reading before starting your activity.
NOTE: In cold environments, warm up indoors.
• Rinse the device with fresh water after each workout.
