Slim, light and waterproof, the Polar T31/T34 Non-Coded Chest Transmitter transmits your heart rate to your wrist unit ECG (electrocardiogram) accurately.

Fully water resistant making it great for swimmers, it delivers the most effective measurement of your heart rate while involved in water sports.

Unlike the coded version It doesn’t have the benefit of coding for interference free transmission.

While the battery is not user replaceable (It is suggested that the battery (ce0537) be replaced by Polar.),  you won't need to worry much as the long lasting battery it comes standard with delivers 2,500 hours of operation, or 5 years of use exercising at 10 hours a week.
