Our smallest and lightest module fits within the width of the strap. Its soft, rounded edges and covered seams make the strap super-comfortable out of the water, too.
HRM-Tri also has an accelerometer in the module that measures torso movement to calculate 3 different running metrics:
The number of steps per minute. It displays the total steps (right and left combined).
The bounce in your running motion. It displays the vertical motion of your torso (measured in centimetres). HRM-Tri is compatible with several other fitness products but will only display heart rate when paired.
The amount of time in each step that your foot spends on the ground while running (measured in milliseconds).
