Compatible with any Bluetooth device that allows you to monitor heart rate, heart rate monitor COROS It offers more than 38 hours of continuous and accurate heart rate monitoring to track your workouts in total comfort and without distractions.

Easier to wear than a chest strap, the soft fabric band lies flat around the arm and stays in place thanks to its textured surface. The low-profile design prevents it from snagging on clothing or gym equipment, allowing you to forget you're wearing it.

You can adjust the placement and perfect tightness of the durable elastic band for your arm by simply sliding the buckle until it is snug. The secure velcro closure allows for quick removal of the sensor for easy washing of the band.

The latest generation multi-channel optical sensor provides high image quality signal. Housed in a durable yet stylish body and protected under a scratch-resistant cover, the advanced sensor will provide reliable and accurate heart rate data for years to come. Optical heart rate sensors work best when held firmly against the skin. The band is designed so that the sensor sits flush against your arm and prevents outside light from entering to keep the signal quality strong, regardless of your activity.

Thanks to integrated wear detection, the COROS heart rate monitor automatically switches on and off depending on when it is being worn. This allows you to automatically connect to your paired devices every time you start training.
