HRM 600, from the Garmin brand, is a premium heart rate monitor, designed for athletes who seek accurate data on their heart rate and HRV, as well as running dynamics. The HRM 600 sends accurate, real-time heart rate and HRV data to your compatible Garmin smartwatch, your Edge bike computer, your compatible fitness devices, the Tacx Training app, as well as other applications. Improve your technique with running dynamics, including ground contact time balance impact deceleration to see how much you slow down when your foot hits the ground, in addition to vertical oscillation, ground contact time and balance (requires a compatible smartwatch). During activities where you cannot wear a watch, such as team sports or martial arts, the HRM 600 heart rate monitor records your training data, including heart rate, calories, pace and distance, then syncs it directly to the Garmin Connect app. Your HRM 600 tracks daily metrics, such as step count, heart rate, calories burned and intensity minutes, and syncs them directly to the Garmin Connect app to update them across all your devices. For indoor and treadmill running, the HRM 600 heart rate monitor sends pace and distance to your compatible smartwatch. During swimming activities, your HRM 600 stores your heart rate data and transfers it to your compatible smartwatch when your activity is saved. The LED indicator lets you know when your HRM 600 is active and ready to use, or when the battery is low. By pressing the button, you can easily activate and pair your heart rate monitor. Additionally, the HRM 600 is durable and water-resistant up to 5 ATM.
