Hammerhead Karoo 2.0 Heart Rate Sensor
The Hammerhead Karoo 2.0 heart rate sensor uses a conductive rubber material that is highly sensitive and capable of detecting heart rate in all conditions. The material has excellent resistance to ageing, temperature, and oxidation. The construction is flexible and allows for consistent and long-lasting heart rate detection. The electrodes feature a patented honeycomb pattern that increases the contact surface with the skin and improves moisture drainage. It also enhances the electrode's contact with the skin, preventing the strap from moving up and down the chest during intense exercise.
