HRM 600 Heart Rate Strap

From Garmin

Heart rate monitor captures accurate heart rate, HRV and running dynamics; also provides stand-alone activity recording.

CONNECTIVITY - HRM 600 sends accurate real-time heart rate and HRV data to your compatible Garmin smartwatches and Edge® bike computers, compatible fitness equipment, the Tacx Training™ app and other apps.

EXPANDED RUNNING DYNAMICS - Improve your running form with running dynamics, including step speed loss1 to understand how much you slow down when your foot hits the ground, in addition to vertical oscillation and ground contact time and balance (requires compatible smartwatch2).

ACTIVITY RECORDING - During activities where you can’t wear a watch, such as team sports or martial arts, the HRM 600 heart rate monitor will record your workout and sync data — including heart rate, calories, speed, distance and more — directly to the Garmin Connect app3.
