Details that matter
The Hammerhead heart rate monitor uses a highly sensitive conductive rubber material capable of measuring heart rate in any condition. The material has excellent resistance to aging, temperature, and oxidation. The structure is flexible, allowing constant heart rate detection and longer durability. The electrodes feature a patented honeycomb pattern that increases skin contact area and improves breathability. Additionally, it enhances electrode contact with the skin and prevents the strap from moving up and down on the chest during intense exercise.
