T31 TRANSMITTER

SLIM AND LIGHT TRANSMITTER THAT IS FULLY WATER RESISTANT AND DESIGNED FOR ALL WEATHER CONDITIONS.

Slightly different to the T31c Transmitter, the slim, light and waterproof T31 doesn’t have the benefit of coding for interference free transmission. However, its purpose remains the same: to transmit your heart rate to your wrist unit ECG (electrocardiogram) accurately.
No user replaceable battery
