NOTE
When the no-decompression time
remaining is one minute, an audible alarm
is sounded to indicate that the diver is
about to exceed the no-decompression
limits.
TIME TO SURFACE ASC TIME
The ascent time is given by the sum of:
• duration of the various decompression stops;
• Time required to ascend at an average speed of
10 m/min (32 ft/min).
• Any deep stops.
DECOMPRESSION STOPS
Nemo Wide also checks that the decompression
stops are observed; two icons graphically indicate
how the diver must behave (Fig. 15).
FIG. 15
• 2 triangles: correct decompression stop depth;
• upward triangle: diver below decompression
stop depth, ascend!
• downward triangle: diver has ascended beyond
decompression stop depth, descend!
!
WARNING
When the omitted deco stop alarms are
triggered, desaturation of the simulated
tissue compartments is halted and resumes
only when the diver returns to the correct
stop depth.
If the decompression stop depth is exceeded
by more than 30 cm (11 inches), the “downward
triangle” icon will flash; if it exceeds 1m (3 ft) it keeps
flashing and an audible alarm will sound. These
warnings remain active until the diver returns to the
correct depth.
!
WARNING
Never ascend above the correct decompression
stop depth.
NOTE
If the deco-stop overshoot
exceeds one meter and lasts
more than three minutes,
the computer switches to
“Omitted Stop” mode and the
corresponding icon appears.
In this case, if the diver attempts
a repetitive dive after surfacing,
Nemo Wide will only function
as a depth gauge and timer (BT
mode), and it will display the
errors of the preceding dive.
DEEP STOPS
To minimize the likelihood of critical bubble seed
formation, in the case of decompression dives
or dives close to the no-deco limit, Nemo Wide
prompts for a series of one-minute deep stops at
different depths depending on the dive profile.
Thus, when the conditions exist during the dive,
Nemo Wide will display a “deep stop” icon (Fig. 16).
FIG. 16
This display is helpful in planning the deep stop
during the ascent. When the diver approaches a
deep stop, Nemo Wide sounds an audible alarm
and the “DEEP STOP” message appears on the
display bar.
At the depth indicated a countdown will appear
indicating the time left in the DEEP STOP (Fig. 17).
There can be more than one deep stop during a
dive. This depends on the dive profile and on the
type of decompression.
