Heart Rate Monitor Arm Band

No buttons. No fuss.

With 38 hours of full operation or 80 days of standby on a single charge, the COROS Heart Rate Monitor is built to endure. View the battery level on your COROS watch or app and use the magnetic cable to quickly recharge. Simpler to wear than a chest strap, our soft fabric band lays flat around your arm and locks in place with its textured surface. The low-profile design prevents snagging on clothes or gym equipment, allowing you to forget you're even wearing it. Set the perfect placement and tension on the durable elasticated band by simply sliding the buckle until it feels snug. The secure velcro enclosure enables you to quickly remove the sensor to easily wash the band. With built-in wear detection, the COROS Heart Rate monitor automatically powers on and off based on when it is worn. Allowing you to automatically connect to your paired devices every time you start a workout. Designed to work seamlessly with your favorite COROS watches and app, it can also simultaneously pair with up to three devices, including non-COROS watches and other Bluetooth-compatible indoor trainers, bike computers, and more.
