Heart Rate While Swimming

NOTE: If both wrist-based heart rate and chest heart rate data are available, your device uses the chest heart rate data.

To view your heart rate data, you can add heart rate data fields (Customizing the Data Screens). Heart rate data is not visible while the heart rate accessory is underwater.The HRM-Tri accessory and the HRM-Swim accessory record and store your heart rate data while you are swimming. You must start a timed activity on your paired Forerunner device to view your stored heart rate data later. During rest intervals when you are out of the water, the heart rate accessory sends your heart rate data to your Forerunner device. Your Forerunner device automatically downloads stored heart rate data when you save your timed swim activity. Your heart rate accessory must be out of the water, active, and within range of the device (3 m) while the data downloads.
