The Garmin HRM 600 is a premium heart rate monitor designed for athletes and fitness enthusiasts who want accurate real-time training data without relying entirely on a smartwatch. It provides heart rate and heart rate variability data to compatible Garmin smartwatches, cycling computers, fitness equipment and compatible fitness apps. The HRM 600 can also record activity independently when you cannot wear a watch. During compatible activities, it can record heart rate, calories, speed, distance and other workout information and then synchronise the data with the Garmin Connect app. Advanced running dynamics provide additional information such as stride length, vertical oscillation, ground contact time balance and step speed loss when paired with compatible Garmin equipment. These insights can help runners better understand their running form and improve training efficiency. The adjustable strap is designed for comfortable use during workouts and can be removed and machine washed after training. The XS-S version is suitable for chest circumferences from approximately 60 to 85 cm. The rechargeable battery provides up to 2 months of battery life, reducing the need for frequent charging. The monitor also supports ANT+ and Bluetooth connectivity for flexible pairing with compatible devices and apps. It is water resistant to 5 ATM and can store heart rate data during swimming for later synchronisation.
