The Polar H2 Heart Rate Sensor allows you to monitor your heart rate on all compatible Polar devices thanks to its use of both 5 kHz and 2.4 GHz W.I.N.D. transmission. It is also compatible with many gym equipment units, which often have the Polar logo on them to identify this.

<>In addition, Polar H2 Heart Rate Sensor can be used while you are swimming with compatible Polar units which support 5 kHz transmission.*

The soft textile chest strap supplied with the H2 Sensor adapts to your body shape for your comfort and to maintain your full freedom of movement as you train.

A convenient hook system makes the belt easy to put on and take off.
