Product Details

Hit your training goals and get more out of your Karoo with real-time heart rate data. A washable chest-strap designed for fit and comfort, including conductive rubber electrodes, allows for great connectivity and durability.

The Hammerhead Heart Rate Monitor uses a conductive rubber material that is highly sensitive and capable of detecting heart rate in all conditions. The material has excellent resistance to aging, temperature and oxidation. The construction is flexible and allows consistent heart rate detection and durability. The electrodes feature a patented honeycomb pattern that increases the skin contact surface area and improves moisture drainage. It also improves electrode contact with the skin, preventing the strap moving up and down on the chest during intense exercise.
