When a diver has completed a dive, and is ascending
to the surface, the speed at which a diver can ascend
to the surface, without stopping for decompression, is
decided according to the diving depth and diving time.
These limits are marked as no decompression limits.
The no decompression limits which are on the watch
band, are based on the US navy diving manual (1985
edition).
