Details of the COROS heart rate monitor

• Slim and snug: The soft fabric band is easier to wear than a chest strap. It lies flat around your arm and sits firmly in place thanks to its textured surface. The flat design prevents snagging on clothing or gym equipment, so you can forget you're even wearing it.
• Flexible fit: Adjust the perfect position and tension of the durable elastic band for your arm by simply sliding the buckle until it feels comfortable. Thanks to the secure Velcro fastener, you can quickly remove the sensor and simply wash the strap.
• Advanced sensor: The latest generation optical multi-channel sensor offers high signal quality. Housed in a robust yet stylish casing and protected by a scratch-resistant cover, the advanced sensor delivers reliable and accurate heart rate data for years to come.
• Superior band: Optical heart rate sensors work best when they are firmly attached to the skin. The band is designed so that the sensor sits flush against your arm, preventing outside light from penetrating and maintaining signal quality regardless of your activity.
• Long-lasting performance: With 38 hours of full use or 80 days of standby on a single charge, the COROS heart rate monitor is built to last. View the battery level on your COROS watch or app and use the magnetic cable for quick charging.
• Wear detection: With integrated wear detection, the COROS heart rate monitor automatically switches on and off depending on when it is worn. This allows you to automatically connect to your paired devices every time you start a workout.
• Multiple connections: The device is designed to work seamlessly with your favorite COROS watches and apps. But it can also be paired with up to three devices simultaneously, including non-COROS watches and other Bluetooth-compatible home trainers, bike computers and more.
• Why the arm: Optical heart rate sensors use light to measure blood flow in the capillaries under the skin. The top of the wrist is a convenient place for a watch, but it's a difficult position for even the best sensors. Wearing it on the arm provides our optical sensor with an optimal amount of blood flow to capture heart rate data with an accuracy equivalent to a traditional chest strap.
