The COROS Heart Rate Monitor offers a superior alternative to traditional chest straps, providing elite-level accuracy with the comfort of a soft fabric arm band. Compatible with any Bluetooth-enabled heart rate device, it is designed to deliver distraction-free monitoring for runners, cyclists, and fitness enthusiasts.

Advanced Optical Sensor Technology

Equipped with a latest-generation multi-channel optical sensor, this monitor provides high signal quality for precise heart rate tracking. By wearing the device on the arm, the sensor benefits from optimal blood flow, gathering data with accuracy equivalent to a traditional chest strap while remaining much easier to wear.

Seamless Connectivity and Wear Detection

With built-in wear detection, the monitor automatically powers on when placed on the arm and shuts off when removed. It supports up to three simultaneous Bluetooth connections, allowing you to sync data across your COROS watch, indoor trainers, bike computers, and mobile apps all at once.

Exceptional Battery Life

Engineered for endurance, the COROS Heart Rate Monitor provides up to 38 hours of continuous operation on a single charge. In standby mode, the battery can last up to 80 days. Charging is simple and fast using the included magnetic USB charging cable.

Superior Fit and Durability

The soft fabric band lays flat against the arm to prevent snagging on clothing or gym equipment. The elasticated band and secure velcro enclosure allow for quick adjustments and easy removal. The sensor is protected by a scratch-resistant cover housed in a tough, low-profile body.
