- 127 - ABSTRACT OF THE DISCLOSURE The indicating device is driven through at least one memory for the decompression parameters at a series of diving depths and times, and an evaluation and logic stage for the measured values of the depth gauge and timer, with the values stored in the memory. At any time during the dive the necessary total resurfacing time (15), including the prescribed decompression stops (16) which depend on the dive depths (14) and times (13), can be indicated, and/or a converter device is provided for conversion of the present bottom-time, on entering a new diving depth stage, into the equivalent bottom-time for this new diving depth stage. A single pressure sensor, preferably a piezoresistive load cell, is used both for the atmospheric and the water pressure and can be switched to the two ranges. LED indicators light up if the maximum ascent rate is exceeded (10), when a decompression stop is reached (11), and if the equipment becomes inoperative because the permissible times and/or depths have been exceeded (12).
