What Do I Need to Do to Take Advantage of This Feature?

The software on your watch needs to be up to date. If your watch is paired to the Garmin Connect™ app on your smartphone, updates are sent automatically to the watch. You can also use the Garmin Express™ program on a personal computer to manually update the software. See How Do I Install Garmin Express? for full instructions.


Can I Turn This Feature On or Off?

With the latest software, most watches will have the optical heart rate sensor enabled automatically when performing a Swim activity. To see if your watch has the option to enable or disable this setting, check your owner's manual or see if your device has the following options. 

  1. Press and hold the MENU button.

  2. Select or scroll to Settings 

  3. Select Sensors & Accessories or Health & Wellness

  4. Select Wrist Heart Rate.

  5. Select While Swimming.

  6. Toggle setting On or Off.


How Accurate Is the Wrist Heart Rate When Swimming?

Swimming can have many of the challenges which are described in The Heart Rate Sensor on My Garmin Watch Is Not Accurate. The large arm motions can affect the level of blood volume in the wrist area, chilly water can reduce the amount of blood in the tissue on the back of the wrist, and the water can “pull” on the watch creating a gap between the optical heart rate sensor and the skin. The same tips apply to swimming as other types of activities. Warm up a bit before starting the swim activity and make sure you are properly wearing the watch. Specifically:

  • The optical heart rate sensor must always remain in contact with your skin.

  • The watch must also be worn snug, but not too tight.

    • Too loose the watch can slide around, creating a gap between the optical heart rate sensor and your skin.

    • Too tight and the watch can actually restrict blood flow.

  • The watch is properly snug when you can move the watch and the skin underneath moves with it.

For best heart rate accuracy during swimming, use the HRM 600, HRM-Pro™, HRM-Pro™ Plus, HRM-Swim™, or HRM-Tri™ heart rate monitors.
