The COROS Heart Rate Monitor delivers accurate and comfortable heart rate monitoring. Easier to wear than a chest strap, it features a soft, adjustable fabric band and a multi-channel optical sensor for precise measurements. Compatible with any Bluetooth heart rate-enabled device, it supports up to 3 simultaneous connections. With wear detection, the monitor automatically pairs with your devices at the start of a workout. It provides 38 hours of full operation or 80 days in standby mode on a single charge, and is rechargeable with a magnetic USB cable.
Designed for distraction-free comfort, the COROS Heart Rate Monitor lays flat around your arm, secured by a durable, elasticated band with a velcro enclosure. The advanced optical sensor is housed in a scratch-resistant cover, providing reliable data for years. The band ensures the sensor is flush against your arm, preventing external light interference and maintaining strong signal quality.
Optical heart rate sensors perform best when securely held against the skin. The COROS Heart Rate Monitor is designed to be worn on the bicep, offering optimal blood flow for accurate data, comparable to traditional chest straps. Seamlessly pair it with your favorite COROS watches and app, as well as up to three other Bluetooth-compatible devices such as indoor trainers and bike computers.
