Pair your compatible Garmin device with the Run Heart Rate Monitor to get your heart rate and real time feedback about your running form. Features an accelerometer in the module that measures torso movement to calculate 3 running metrics: Cadence or the number of steps per minute. It displays the total steps right and left combined. Vertical oscillation or the bounce in your running motion. It displays the vertical motion of your torso measured in centimeters. Ground contact time or the amount of time in each step that your foot spends on the ground while running measured in milliseconds. Note : Running dynamics features are available only on the Forerunner 620 and Fenix 2. Device is compatible with several other fitness products but will only display heart rate when paired.
