Stores Heart Rate Underwater and Forwards Data
Take your training to the next level by pairing HRM-Swim with a compatible Garmin watch1. The sleek, nonslip strap stays in place, even during wall push-offs. Once you’re resting out of water, real-time heart rate, interval summaries and stored heart rate are transmitted to your watch.
HRM-Tri also has an accelerometer in the module that measures torso movement to calculate 3 running metrics:2
- Cadence — the number of steps per minute. It displays the total steps (right and left combined).
- Vertical oscillation — the bounce in your running motion. It displays the vertical motion of your torso (measured in centimeters). HRM-Tri is compatible with several other fitness products but will only display heart rate when paired.
- Ground contact time — the amount of time in each step that your foot spends on the ground while running (measured in milliseconds).
