The Details that Matter

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.

Connect and Go

Dual Bluetooth channels and ANT+ allow you to pair to two bluetooth devices and any number of ANT+ receivers. Pair your Karoo over ANT+ for exceptional battery life out on the road or use it with your smartwatch for running and other bluetooth indoor trainer setups.

Don’t Sweat It

A water-proof design means you don’t have to worry about sweat or water interfering with your sensor while riding. Absorbent and elastic materials allow the strap to stay in place on your chest when the sweat starts pouring. When you're done riding, easily remove the sensor casing to wash the strap and be ready for your next ride.

Ride the Distance

One of the lightest pods and straps on the market at 15 grams and 28 grams respectively. The patented electrodes increase reliability in all conditions while the exceptional battery life keeps you riding and reduces waste with less batteries.
