The Table represents a new concept, in that it eliminates portrayal of repetitive groups, residual nitrogen times, multiple lines, arrows and flow charts. The main features of the table are it's conservatism and simplicity. However, it can be very easily used to introduce the U.S. Navy tables as well. Before publication, the No-D table was reviewed by some of the leading decompression experts in North America. Their input was integrated into the dive table's procedures.
Divers can record their dive profile information on the back of the table as well.
The minimum surface interval required is 30 minutes. The table allows for as many as three no-decompression dives, followed by a maximum surface interval of 16 hours. The table conforms as well to the U.S. Navy table concept of a shallower depth for each successive dive. This means that a beginner could make up to three dives at depths of 50' or less. On the other hand, a more experienced diver could make tow dives between 60' and 90' and make a third dive at 50' or less.
