Parameter measurement
The heart rate sensor provides over 38 hours of continuous, accurate measurement, so you can track your workouts with such comfort that you'll forget you're wearing it.
Duration of use
38 hours of full operation or 80 days in standby mode
Comfort and convenience
The soft fabric cuff lies flat around your arm and stays in place thanks to its rough surface.
The discreet design prevents it from clinging to clothing, so you can practice without discomfort.
Adjust the position and tension of the resistant elastic cuff on your arm by simply sliding the buckle until it fits snugly. The secure Velcro fastener lets you quickly remove the sensor to easily wash the cuff.
Advanced sensor
The latest-generation multi-channel optical sensor delivers a high-quality signal. Housed in a robust yet elegant casing and protected by a scratch-resistant cover, the sensor will provide reliable, accurate heart rate data for years to come.
High-quality cuff
Optical heart rate sensors work best when held firmly against the skin. The cuff is designed to place the sensor against your arm to keep out external light and maintain signal quality, whatever your activity.
Resilient power
With 38 hours of full operation or 80 days of standby on a single charge, the COROS heart rate sensor is built to last. Check the battery level on your watch or the COROS app, and use the magnetic cable to recharge quickly.
Detection
Thanks to built-in wearable detection, the COROS heart rate monitor switches on and off automatically depending on when it is worn. It allows you to connect automatically to app-coupled devices every time you start a workout.
Multiple connections
Designed to work seamlessly with your favorite COROS watches and apps, it can also pair simultaneously with up to three devices, including non-COROS watches and other Bluetooth-enabled gym equipment, bike computers and more.
Why the arm?
Optical heart rate sensors use light to measure blood flow in the capillaries beneath the skin. The top of the wrist is a convenient location for a watch, but not the best for sensors. Wearing it on the arm gives the optical sensor an optimum amount of blood flow to gather heart rate data with the same precision as a traditional chest belt.
