3.2.1.6. DECOMPRESSION DIVES
When your NO DEC TIME becomes zero, your dive becomes a decompression stop
dive, i.e. you must perform one or several decompression stops on your way to the
surface. The NO DEC TIME on your display will be replaced by a CEILING and
blinking ASC TIME notation and an upward pointing arrow (Fig. 3.17.).
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 subsequent interval and repetitive dive information.
Rather than requiring you to make stops at fixed depths, the dive computer gives
you the option to decompress with a more gradual and natural series of mini steps
within the decompression range (continuous decompression).
