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.

EASY TO WEAR. NOTHING TO DISTRACT.

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.

DESIGNED FOR ACCURACY. BUILT TO LAST.

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.

SUPERIOR BAND

Optical heart rate sensors work best when they're held securely against the skin. Our band is designed to cradle the sensor flush against your arm to prevent external light from getting in to keep the signal quality strong, no matter your activity.

NO BUTTONS. NO FUSS.

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.

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.
