Train and compete with more heart than ever before with HRM Swim and HRM Tri, heart rate monitors designed to track underwater. Enhance your triathlon experience by pairing HRM-Tri and HRM-Swim with Forerunner 920XT for a much more unified approach to training and racing. The non-slip HRM-Swim is perfect for pool swimming with wall push-offs. On land, in open water and for racing, use HRM-Tri’s ultra-soft strap that’s as comfortable out of water as it is underwater. Both store and forward heart rate data to Forerunner 920XT.
