The depth of the ceiling and fl oor will depend on your
dive profi le. The ceiling depth will be fairly shallow
when you enter the decompression mode, but if you
remain at depth, it will move downward and the as-
cent time will increase. Likewise, the fl oor and ceiling
may change while you are decompressing.
When the sea surface is rough, it may be diffi cult
to maintain a constant depth near the surface. In
this case it will be more manageable to maintain
an additional distance below the ceiling, to make
sure that the waves do not lift you above the ceiling.
SUUNTO recommends that decompression takes
place deeper than 4 m [13 ft], even if the indicated
ceiling is shallower.
NOTE! It will take more time and more air to
decompress below the ceiling than at the ceiling.
DISPLAY BELOW THE FLOOR
The blinking ASC TIME and an upward pointing
arrow indicate that you are below the fl oor (Fig.
3.16). You should start your ascent immediately.
The ceiling depth is shown on the right corner and
the minimum total ascent time on the right side of
the center window.
DISPLAY ABOVE THE FLOOR
When you ascend above the fl oor, the ASC TIME
display stops blinking and the upward pointing ar-
row disappear (Fig. 3.17). Decompression will now
begin, but is very slow. You should therefore continue
your ascent.
Fig. 3.17 Decompression dive,
above the fl oor. The upward
pointing arrow has disappeared
and the ASC TIME label has
stopped blinking, which means
that you are in the decompres-
sion range.
Fig. 3.16 Decompression dive,
below the fl oor. The upward
pointing arrow and the blinking
ASC TIME label tell you to
ascend. The minimum total
ascent time including the safety
stop is 7 minutes. The ceiling is
at 3 m [10 ft].
