Garmin HRM-Tri

Specifically designed for triathletes, the Garmin HRM-Tri is their smallest and lightest heart rate monitor, which fits within the width of the strap. The HRM-Tri stores heart rate data when underwater, then forwards it to your wearable at the end of your swim. When running, this pairing allows your compatible wearable to report 6 running dynamics metrics: cadence, stride length, ground contact time, ground contact time balance, vertical oscillation and vertical ratio.

Features:

• Easily adjustable strap
• Soft, rounded edges and covered seams to provide comfort
• Stores and forwards heart rate data to Forerunner® 920XT
• Typically used for bike rides, runs, triathlon (open water swimming) and triathlon (pool swim) while wearing triathlon kit
