COROS Heart Rate Monitor
The alternative to a chest strap that delivers accurate heart rate data.
Your wrist-based heart rate monitor is convenient, but it's not always reliable. Spotty readings during intervals, lag during rapid heart rate changes, and completely unreliable data during strength training—sound familiar? The COROS Heart Rate Monitor solves every one of these frustrations by tracking your pulse directly from your bicep, delivering the most accurate heart rate data you've ever had.
Arm-Based Precision In Every Beat
At just 9.7g for the sensor alone, this comfortable armband transforms any Bluetooth-compatible device into a precision heart rate system that responds instantly to changes, works flawlessly during any activity, and provides insights wrist monitors simply can't match.
Why arm-based heart rate tracking is better:
- Zero wrist interference - No more gaps from wrist movement or sweat
- Strength training accuracy - Reliable readings during weights and hybrid workouts
- Instant response - Advanced optical sensors capture heart rate changes instantly
- Multi-device connectivity - Connect to 3 devices simultaneously for complete training ecosystem
Highlights of COROS Heart Rate Monitor:
Precision Optical Technology: 5 LED lights with 4 photodetectors deliver clinical-grade accuracy that responds instantly to heart rate changes, even during the most demanding workouts.
Armband Comfort Revolution: Forget uncomfortable chest straps. The soft polyester-nylon-spandex blend sits comfortably on your bicep (fits 7.09-12.6 inches) without restricting movement or breathing.
