Couple the HRM Swim with the Forerunner® 920XT and get more out of your triathlon

The HRM Swim was made specifically for use in swimming pools. It has a non-slip strap that will not slip even when pushing up from the water's edge. If the device is no longer in the water, for example, when the upper body emerges from the water during training, real-time heart rate data, interval overviews and stored heart rate data is sent to the 920XT.

  • Swimming pool
