COROS Heart Rate Monitor (Jakob Ingebrigtsen Gold) 18-32cm Bicep

The gold-tier choice for heart rate monitoring, designed for extreme comfort and engineered for those who demand accurate training data.

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 upper 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.

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.

• 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. 
• Arm Size: 18-32cm (standard)
