Precise data. Total comfort.
Compatible with any Bluetooth heart rate-enabled device, the COROS Heart Rate Monitor delivers over 38 hours of continuous accurate heart rate monitoring to track your workouts in distraction-free comfort.
Sleek & Snug
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.
Flexible Fit
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.
Advanced Sensor
Our latest generation multi-channel optical sensor provides high signal quality. Housed in a tough yet sleek body and protected under a scratch-resistant cover, our advanced sensor will deliver reliable and accurate heart rate data for years.
Lasting Power
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.
Wear Detection
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.
Multiple Connections
Designed to work seamlessly with your favourite 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.
Why The Arm?
Optical heart rate sensors work by using light to measure blood flow in capillaries beneath the skin. The top of your wrist is a convenient place for a watch, but is a challenging location for even the best sensors. Wearing on the arm offers our optical sensor an optimal amount of blood flow to gather heart rate data with accuracy equivalent to that of a traditional chest strap.
