Claims

[Scope of Claim for Utility Model Registration] (1) The no-decompression diving time, surface rest time, or nitrogen residual time for each depth and repetition group symbol of the dive table is written in the division column divided into three on one side of a disc made of water-resistant material.・Each column for repeated diving limit time is arranged radially, and flat plates are overlapped so as to cover this surface, and the center points of the disc and the flat plate are pivotally connected with a stopper, and this flat plate has the above water depth. A punched-out window is provided to display only a small column for the no-decompression dive time or surface interval time or nitrogen residual time/repetitive dive limit time in units or repetition group symbol units, and the no-decompression dive time or surface interval is displayed on the side of this window. A quick reference board for a dive table, characterized in that repetition group symbols corresponding to time, nitrogen residual time, and repetition diving limit time are provided. (2) A utility model characterized in that a decompression table for diving exceeding the no-decompression limit is provided on the surface of the flat plate on the opposite side to the disc, in correspondence with the repetition group symbol provided on the side of the window. A planisphere dive table according to claim 1. (3) The disc was held between the flat plate and a second flat plate, the center points of which were pivotally connected by a stopper, and a space for writing a diving schedule was provided on the surface of the second flat plate on the side opposite to the disc. A dive table plan view board according to claim 1 or 2 of the utility model registration claim, characterized in that:
