Train more effectively with the Smart Heart Sensor. When worn around your chest during an activity, it wirelessly transmits your heart rate to your compatible device for instant feedback on how hard you’re working.
The Smart Heart Sensor is designed to work with the latest smart devices equipped with Bluetooth 4.0 technology. Also known as low energy Bluetooth, this new wireless transmission allows sensors to be used for months if not years without changing batteries.
Once it’s paired with your compatible device the first time, it will automatically recognise it each time. And it's optimised for use in crowded areas like the gym and road races, so it won’t pick up any signals but your own.
The strap is made of a soft fabric for more comfort. The size is adjustable to your body so it stays secure during your activity.
Works with any Bluetooth Smart ready devices such as iPhone Se/5s/5/4S, iPad Mini & iPad 4
