The HRM-Tri is designed for the triathlete and is the smallest and lightest monitoring strap that will capture your heart rate data from all three disciplines, swimming, running, and biking. The HRM-Tri is also easily adjusted, and it is soft with rounded edges so you can give your best effort without an annoying scratch or feeling your chest restricted. Battery life for the HRM-Tri is 10 months. The HRM-Tri in addition to heart rate data will also record running dynamics and send that data as well to your compatible watch.
