Abstract: Novel display scheme for decompression data is herein presented which can be animated by various types of decompression computers and permits the use of new, highly advantageous procedures in many aspects of diving, notably: (1) no-decompression diving, (2) decompression diving, and (3) repetitive diving. It allows a diver to choose his margin of safety, lending itself to use by divers predisposed to DCS, or by divers working under arduous conditions. It consists of graphical and digital display elements which accesses the contents of a microprocessor or other information source as to a diver's tissue's state of saturation with inert gas. This information is presented to a diver in a simple, straight forward and non-confusing manner which allows him/or to use the new highly advantageous procedures.
