The Silver Lining
Most heart rate monitors use polymer electrodes which are uncomfortable and degrade over time. The Hammerhead Heart Rate Monitor uses an all-fabric strap design in which silver fibers are woven into the fabric electrodes for highly sensitive and accurate ECG signal detection even on users with low skin impedance.
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 waterproof 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 naturally antibacterial silver electrodes reduce skin irritation while the exceptional battery life keeps you riding and reduces waste with less batteries.
