ABSTRACT:
Disclosed is a diving computer in the form of a circular slide rule for aiding a SCUBA diver in planning one or more dives within a short amount of time, including more than one depth per dive, so that the diver may avoid risking decompression sickness. The computer has two faces, one of which calculates the increase of pressure within body tissues during a dive and the other of which calculates the decrease of this pressure after surfacing. The result of one side's calculation is used as the initial value for the other side's calculation, permitting the diver to track net residual pressure over a series of rapid repeated and/or multiple-level dives, and by so doing, avoid excessive tissue pressures that might cause decompression sickness.
