- FEATURES -

• TRACK RUNNING DYNAMICS
  In addition to heart rate, HRM-Pro captures running dynamics that can help you improve your form. That includes metrics such as vertical oscillation, ground contact time, stride length, vertical ratio and more.

• STORE AND FORWARD YOU DATA
  The device stores heart rate data during swimming or other activities while your watch is out of range, then sends that data to your watch once the activity is finished. It will also store steps, calories and intensity minutes, then sync them to your watch as well.

• COMFORT AND CONVENIENCE
  HRM-Pro features a small, lightweight heart rate monitoring module that is no wider than the width of the soft, comfortable strap. And don’t worry about running out of juice. The user-replaceable coin cell battery lasts for up to one year.
