3.4.5 Decompression dives
WARNING!
DO NOT USE THIS INSTRUMENT TO CONDUCT DECOMPRESSION DIVES!
Suunto does not recommend this instrument to be used to conduct decompression
dives. However, if through carelessness or emergency a diver is forced to 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 permits you
to decompress within a range of depths.
BACKGROUND
When your NO DEC TIME becomes zero, your dive becomes a decompression 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 flashing notation CEILING/ ASC
TIME (Fig. 3.14).
WARNING!
YOU SHOULD ASCEND AND BEGIN DECOMPRESSION IMMEDIATELY WHEN
THE DIVE COMPUTER SHOWS YOU THAT DECOMPRESSION IS REQUIRED!
Note the upward pointing arrow.
Fig. 3.14 DECOMPRESSION DIVE,
BELOW THE CEILING ZONE
The minimum ascent time is 4 minutes. The
upward pointing arrow tells you to ascend.
The ceiling is at 3 m [10 ft].
Fig. 3.15 DECOMPRESSION DIVE, AT
THE CEILING ZONE
The two arrows (a) point at each other ("hour
glass"). You are at the ceiling zone at 3.5 m [11
ft] (c) and your minimum ascent time is 3
minutes (d). The ceiling is at 3 m [10 ft] (b).
