COROS Heart Rate Monitor Jakob Ingebrigtsen Edition

HRM-JAK Comfortable and simpler to wear than a chest strap. Easy to adjust the fit and remove the sensor for quick cleaning. Our latest multi-channel optical sensor for precise measurement. Up to 3 simultaneous connections with Bluetooth-enabled devices. Wear detection allows for automatic device pairing for new workouts. 38 hours of full operation or 80 days in standby mode on a single charge. Rechargeable with a magnetic USB charging cable. UNMATCHED COMFORT Ultra-soft fabric lays flat against your arm and locks into place with a textured surface that won’t budge during your 20-mile Sunday long run, or tempo laps around the track. JACQUARD BAND Instead of a printed pattern, the "Fearless" Jacquard features an intricate weave that provides deeper texture and a more secure hold. The high-tenacity nylon locks in color and keeps its elasticity for years to come. ACCURATE, ALL THE TIME The low-profile design is held firmly on your arm to prevent movement, snags, and external light that can cause heart rate data to be inaccurate. WHY THE ARM? Optical heart rate sensors work by using light to measure blood flow in capillaries beneath the skin. The top of your wrist is a convenient place for a watch, but is a challenging location for even the best sensors. Wearing on the arm offers our optical sensor an optimal amount of blood flow to gather heart rate data with accuracy equivalent to that of a traditional chest strap.
