A depth monitoring device monitors the period of a diver's maximum depth. A aximum depth display is coupled to the depth monitor to enable the diver to quickly determine, at any given time during the period, his maximum depth of submergence. When the diver reaches a preselected critical maximum depth, an audio alarm coupled to the depth monitor is activated to alert the diver.
