Enhance your triathlon experience by pairing HRM-Tri with e.g. your Garmin device. The HRM-Tri stores heart rate data when underwater, then forwards it e.g. to your Forerunner® 920XT. Garmin's smallest & lightest module fits within the width of the strap.
Take your training to the next level by pairing HRM-Swim with your ANT+ compatible Garmin device. The sleek, non-slip strap stays in place, even during wall push-offs. Once out of water, measured dates are transmitted to your device.
