Garmin HRM-Swim

Running Heart Rate Sensors & Straps

Customized for pool swimming, the HRM-Swim has a unique non-slip design that keeps it in place during push-offs and withstands repeated exposure to pool chemicals. It stores heart rate data when underwater, and sends real-time heart rate data and interval summaries with the monitor out of the water during rest periods.


Train even better with heart rate by pairing HRM-Swim with Forerunner 920XT, Forerunner 735XT or Fenix 3 HR. The durable, non-slip strap keeps the heart rate monitor in place, even during wall push-offs. Sleek design causes minimal drag and stores heart rate data as you swim. Out of water, real-time heart rate, interval summaries, and stored heart rate are transmitted to the monitors. Stores up to 20 hours of heart rate data. Designed for all swim environments – fresh water, salt water and pools.
