The heart rate sensor measures your heart rate with great accuracy. The HRM-Pro Plus replaces the older Garmin HRM-Pro Plus, the heart rate sensor for runners and HRM-Tri, the heart rate sensor specifically for triathletes. In terms of looks, the HRM-Pro resembles its predecessors, but in terms of features, the HRM-Pro is quite a step forward. The HRM-Pro sensor includes Bluetooth, making it easy to connect the heart rate sensor to smartphones, sports watches and devices that support Bluetooth connectivity. Among other things, the heart rate sensor measures your cadence (the number of steps per minute), ground contact time (the time during which you make contact with the ground while running), ground contact time balance (the balance between the time your left and right foot make contact with the ground), your stride length and your vertical oscilation (the "step height" in your running motion, or the vertical movement of the upper body). The old HRM-Tri also did this, the big difference is that the HRM-Pro can send this data via ANT+ as well as Bluetooth. This gives you more options while training, whether you are training indoors or outdoors. The HRM-Pro allows for two Bluetooth Low Energy connections, allowing you to send measured data via Bluetooth, for example, to both your smartphone and to a sports watch, fitness device or other Bluetooth-enabled device. In addition, an ANT+ connection is also possible. Do you prefer to train without other devices nearby and also prefer to leave your phone and sports watch at home? Then the HRM-Pro stores all data on the internal memory. Via the Store-and-Forward function, the heart rate sensor automatically sends all data to your sports watch or phone after your workout. If you wear the HRM-Pro without a paired sports watch, the sensor also stores other information such as number of steps taken, calories burned and the intensity of your workouts. The HRM-Tri is waterproof to 5 ATM, or 50 meters. Like the older HRM-Tri, the HRM-Pro can also accurately measure your heart rate underwater, making the new Garmin HRM-Pro Plus is also an ideal heart rate sensor for triathletes. The battery in the HRM-Pro lasts about a year with average use (about 1 hour of use per day). The battery is easy to change.
