Sigma Onyx 'Pro' is perfect for ambitious amateur and competitive sportspeople who are interested in very precise preparation and control and use different forms of training to achieve their aims.
Sigma Onyx 'Pro' HRM is approved to medical standards: NO 93/42/EEC.
The Sigma Onyx 'Pro' HRM is digitally coded with preset and individually acceptable endurance and interval training ranges. The training zones can either be calculated in line with IAT (individial anaerobic threshold) or maximum heart rate.
The detailed analysis of the Sigma Onyx 'Pro' is ideal for all professional and ambitious sportspeople and features new innovations including a magnification function for improved readability and a new kind of navigation for intuitive menu guidance. The Sigma Onyx 'Pro' also features 7 memory locations, a lap counter (50 laps with average and maximum heart rate indications), a light and a battery change compartment.
The Sigma Onyx 'Pro' Heart Rate Monitor is equipped with a digital coded chest belt that enables interferance free training. Due to the digital coded transmission this HRM will not display your heart rate 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 and so you need to wear both the transmitter belt and the receiver in order to monitor your heart rate. The Sigma Onyx 'Pro' HRM features a Sleep Mode (when only time and date are displayed), which it switches to automatically if no training is undertaken after 5 minutes, using only very little power. It can therefore be worn as an everyday watch.

Intuitive menu navigation Storage of setting values in case of battery change Quick change battery compartment - a unique feature of Sigma, the Onyx Pro is equipped with a compartment that the user can safely open to change a battery - no need to visit a jeweller! Simply open the battery compartment with the key provided (or with a coin for the chest belt) paying attention to the polarity, then simply change the battery and close compartment. Backlight Water resistant to 10m - do not press under water Personalization with "my name"
At the start of training, synchronisation takes place between the coded chest belt and the heart rate monitor. Consequently the watch only receives data from its own chest belt. The heart rate readings are converted into digital data packages and transmitted to the receiver in the watch. A “time coding & ID procedure” within Sigma Onyx models guarantees that data transmission is significantly more secure compared to analogue heart rate monitors.
