Garmin Forerunner 735XT GPS Triathlon Watch with Wrist-Based Heart Rate

SKU: Garmin_Forerunner_735XT


Garmin Forerunner 735XT GPS Triathlon Watch with Wrist-Based Heart Rate

Garmin Forerunner 735XT GPS Triathlon Watch is Garmin's latest watch with multisport functionality (just push a button to advance from swim to bike to run).

The optical wrist-based heart rate measures exactly that: heart rate (and not under water). To measure running dynamics, you will need an HR strap that can detect your movement. That means either the HRM-Run (included in the Run Bundle) or the HRM-Tri (included in the Tri Bundle). To record your heart rate while swimming, you will need an HR strap that works underwater. That means the HRM-Tri or HRM-Swim (both included in the Tri Bundle).
