Garmin HRM 600

The HRM 600 is designed for athletes seeking detailed performance insights. It provides real-time heart rate and HRV data, along with advanced running dynamics metrics like vertical oscillation, ground contact time, and step speed loss when paired with compatible Garmin smartwatches. The device also features onboard memory, allowing it to record activities independently and sync data to the Garmin Connect app later-ideal for sports where wearing a watch isn't feasible.

This heart rate monitor boasts a rechargeable battery with up to two months of life on a single charge, depending on usage.
