Heart rate signals are detected by the Polar H2 HR sensor and the data is transmitted the compatible polar training computer. The electrode belt is a comfortable fit, allowing full freedom of movement during training.

• The hybrid transmission by 5 kHz and 2.4 GHz (W.I.N.D.) ensures the interference-free detection of your heart rate signal
• The heart rate data is transmitted even when swimming*
• Ergonomic design made of soft fabric material, so that the electrode belt feels like a part of you
• An independent battery replacement is possible

* The heart rate is transmitted into the water on the 5 kHz frequency, the reception is only possible with computers that use this frequency (not W.I.N.D.).
