HRM-Pro

• This premium heart rate strap transmits real-time heart rate data over ANT+connectivity and Bluetooth

• 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
  
• HRM-Pro features a small, lightweight heart rate monitoring module that is no wider than the width of the soft, comfortable strap
