HRM Strap & Transmitter with advanced running dynamics and storage
Enhance your triathlon experience by pairing HRM-Tri with your Forerunner 920XT, fenix 3, or epix watch. The HRM-Tri stores heart rate data when underwater, then forwards it to the compatible Garmin watch when both are above water. Garmin's smallest and lightest transmitter fits within the width of the strap. Its soft, rounded edges and covered seams make the strap super-comfortable out of water too.
