The digital coded ONYX PRO with preset and individually adaptable endurance and interval training ranges is new to the marketplace. The training zones can either be calculated in line with IAT (individual anaerobic threshold) or maximum heart rate.
The detailed analysis of the training units is ideal for all professional and ambitious sportspeople. A magnification function for improved readability and a new kind of navigation for intuitive menu guidance are innovations that characterise this Heart Rate Monitor. 7 memory locations, a lap counter (50 laps with average and maximum heart rate indications),
a light and a battery change compartment round off the features of this precise heart rate watch.
A real professional.
