Sigma Digital Chest Belt for Onyx

The Sigma Digital Chest Belt (transmitter) for the Sigma Onyx range of Heart Rate Monitors includes a Sigma Elastic Strap.

Digital coded transmission offers interferance free training, however your heart rate will not be displayed on gym equipment that has a heart rate receiver built into it - this simply means that your heart rate will be displayed on your wrist instead via your receiver (Sigma Onyx HRM watch) and so you need to wear both the transmitter belt and the receiver in order to monitor your heart rate.
