Coros Heart Rate Monitor

When you want to understand how hard your body is working, reliable heart rate data can make every training session more meaningful. The COROS Heart Rate Monitor is designed to give you accurate, real-time heart rate information from the upper arm, offering a comfortable alternative to a traditional chest strap.

Why It Stands Out?

• Advanced optical sensor: Multi-channel optical technology provides high-quality heart rate data during exercise.
• Upper-arm positioning: Designed to sit securely between the bicep and deltoid for stable readings.
• Comfortable fit: The soft, flexible band stays close to the skin without restricting movement.
• Low-profile design: Sits discreetly under clothing and is less likely to catch on equipment.
• Up to 38 hours of battery life: Track multiple workouts on a single charge.
• Up to 80 days on standby: Conserves power when you’re not training.
• Connect up to 3 devices: Pair with up to three compatible Bluetooth devices simultaneously.
• Wide compatibility: Works with COROS watches, compatible GPS bike computers, indoor trainers and supported fitness apps.
• Up to 120m Bluetooth range: Stay connected to compatible devices over a long range in suitable conditions.
• Automatic wear detection: Recognises when the monitor is being worn and activates the sensor for training.
• Secure adjustable band: Slide the buckle to find the right tension, then secure it with the Velcro closure.
• Two available sizes: Standard fits 18–32 cm arms, while Large fits 24–43 cm arms.
• 3 ATM water resistance: Suitable for training in wet weather conditions.
• Easy to clean: Remove the sensor from the band and rinse it with fresh water after use.
• Bluetooth connectivity: Connects wirelessly without ANT+ support.

Additional Information:

• Made for different sports: Ideal for running, trail running, cycling, gravel, MTB, gym workouts and more.
• Designed to stay in place: A secure upper-arm fit helps minimise movement during training.
• Simple to adjust: Slide the buckle to tighten or loosen the band for a comfortable fit.
• Easy everyday maintenance: Remove the sensor and rinse it with fresh water after each workout.
• Works beyond COROS: Connect to compatible third-party Bluetooth watches, bike computers, indoor trainers and fitness apps.
• No chest strap required: The upper-arm design offers a comfortable alternative for athletes who prefer a different heart rate monitoring experience.
• Works with your COROS watch: Compatible with all COROS watches that support the monitor.
• Use it with your phone: Record heart rate and workout data through compatible third-party apps such as Strava.
• Built for long training sessions: Up to 38 hours of continuous activity tracking means fewer charging interruptions.
• Easy to keep powered: Recharge using the included charging cable when needed.

From everyday workouts to demanding training sessions, the COROS Heart Rate Monitor gives you a simple and comfortable way to stay connected to your heart rate, understand your effort and make every session count.
