6.1.6. DECOMPRESSION DIVES
When your NO DEC TIME becomes zero, your dive becomes
a decompression stop dive, i.e. you must perform one or se-
veral decompression stops on your way to the surface. The
NO DEC TIME on your display will be replaced by an ASC TI-
ME and a CEILING notation will appear. An upward pointing
arrow will also prompt you state your ascent (Fig. 6.10.).
If you exceed the no-decompression limits on a dive, the dive
computer will provide decompression information required for
ascent. After this, the instrument will continue to provide sub-
sequent interval and repetitive dive information.
Rather than requiring you to make stops at fi xed depths,
the dive computer lets you to decompress within a range of
depths (Continuous Decompression).
The ascent time (ASC TIME) is the minimum amount of time
needed to reach the surface in a decompression dive. It in-
cludes:
•
the time needed to ascend to the ceiling at an ascent
rate of 10 m/min [33 ft/min]
Fig. 6.9 Deepstop. You are
advised to make a deeps-
top at 21m. The second in-
dicator shows that you ha-
ve 44 seconds left of your
deepstop.
