This premium heart rate strap from Garmin essentially advances the HRM Dual by adding new features and storage, and combining the capabilities of the HRM Swim and HRM in one strap. It transmits real-time heart rate data over ANT+® connectivity and Bluetooth® Low Energy technology, giving you more training options. It will consistently receive accurate heart rate on your Garmin device, in online training apps such as Zwift or even the compatible fitness equipment at the gym.

In addition to heart rate, HRM-Pro tracks and 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. The device can store and forward your data without access to a wearable or head unit, such as heart rate data during swimming or other activities while your unit is out of range, then sends that data to your watch or unit once the activity is finished. It will also store steps, calories and intensity minutes, then sync them to your watch as well. It supports the Physio TrueUp system.

HRM-Pro features a small, lightweight heart rate monitoring module that is no wider than the width of the soft, comfortable strap (similar in design to that of the HRM Swim. The module is sealed with a silicone ring that is reusable. The user-replaceable CR2032 coin cell battery lasts for approximately one year of average use.
