Comfortable and simpler to wear than a chest strap, the COROS Heart Rate Monitor is easy to adjust and features a multi-channel optical sensor for precise heart rate measurement. Up to 3 Bluetooth-enabled devices can connect simultaneously, making it ideal for versatile workouts. With built-in wear detection, this monitor automatically pairs with your device when you start a workout. Enjoy up to 38 hours of continuous use or 80 days in standby mode on a single charge, and recharge effortlessly using the included magnetic USB charging cable.

Designed for distraction-free comfort, the COROS Heart Rate Monitor lays flat around your arm and locks in place with its textured surface. The elasticated band with a secure velcro enclosure ensures a snug fit, and the sensor can be removed easily for cleaning. Built to last, the advanced optical sensor is housed in a tough, scratch-resistant cover, providing accurate data for years.

Optical sensors work best when held securely against the skin, and this band is designed to cradle the sensor flush against your arm, preventing external light interference and ensuring strong signal quality. With 38 hours of full operation or 80 days of standby on a single charge, the COROS Heart Rate Monitor is built to endure.

This monitor pairs seamlessly with COROS watches and app, as well as up to three other Bluetooth-compatible devices such as indoor trainers and bike computers. The sensor is designed to be worn on the bicep, offering optimal blood flow for accurate heart rate data, comparable to traditional chest straps.
