GraphX was the first Heart Rate Monitor with a colour graphical display. The three colour display works on a similar principle to a tachometer in a car, and shows how hard the heart is working during exercise compared to the active target zone. Cardiozone lets you set a target zone while actually exercising. Once a desired workout level has been reached, a key press activates and sets cardiozone, which works like a cruise control on a car, keeping you within the selected workout level.
