Polar has launched its WearLink+ Transmitter that goes with the Nike+. The WearLink+ Transmitter picks up your heart’s signals and transfers the data into the Nike+ system. The WearLink+ has a water resistant connector and a machine washable textile chest strap that seamlessly adapts to your body shape. The device features a coded 5 kHz transmission which ensures that your Polar training computer finds your heart rate signal. The WearLink+ can also be paired with most modern equipments found in the Gym. It is expected to surface in the US later this month.
