DIVE COMPUTER NEMO WIDE
FIG. 17
NOTE
When the <ESC> button is pressed during
the dive, Nemo Wide will temporarily
display the estimated deep stop required.
The data displayed during the ascent may
vary as a result of the diver’s behavior.
Divers should check this data during the
ascent for more precise information on
the estimated stop.
ASCENT
!
DANGER
A rapid ascent increases the risk of
decompression sickness.
!
WARNING
Disabling the “Stop” on uncontrolled ascent
should only be done by highly experienced
divers, who take full responsibility for the
consequences of this action.
As the diver ascends, Nemo Wide activates the
ascent rate control algorithm, displaying the value
both in m/min (ft/min) and graphically (Fig. 18).
FIG. 18
If the diver’s speed exceeds 12 m/min (39 ft/min),
the “Slow” message appears on the display bar and
Nemo Wide sounds an audible alarm that persists
until the ascent rate returns below the maximum
permitted limit (12 m/min - 39 ft/min).
At the same time as the audible alarm is triggered,
the computer begins monitoring an “Uncontrolled
Ascent”. An ascent is considered “uncontrolled”
when the diver exceeds the maximum rate for a
stretch equal to at least two thirds of the depth at
which the audible alarm was triggered. This criterion
only applies to alarms triggered below a depth of
12 m (39 ft).
In case of an uncontrolled ascent, upon surfacing
Nemo Wide disables the AIR and EAN functions of
Dive Mode, and will only function as a timer and
depth gauge (BOTTOM TIME).
The other operating modes remain active.
The “Stop” on uncontrolled ascent function can be
disabled in Set Dive mode.
SAFETY STOP
If the maximum depth of a dive exceeds 10 meters,
a “Safety Stop” is activated for the ascent. Nemo
Wide suggests that divers take a 3-minute safety
stop between 2.5 and 6 m in depth (8 - 19 ft), and will
display the word “SAFEST”. A Timer located on the
display bar indicates the time needed to complete
the stop (Fig. 19).
FIG. 19
If the diver moves outside the afore-mentioned
depth range, the safety stop timer is halted. When
the diver re-enters the correct depth range, the
safety stop timer resumes from where it left off.
If the diver returns to a depth below 10 m (32 ft), the
safety stop timer will ignore the previously aborted
stop and will start over from scratch. In the case of
a decompression-stop dive, the safety stop extends
the duration of the decompression stop at 3 m (10
ft) by an additional 3 minutes, displaying the safety
stop information as described previously.
SURFACING AIR
When the measured depth is less than 1 m (3 ft),
Nemo Wide considers the dive to be suspended
(“Surfacing”) and halts the dive timer. If the diver
does not return below 1.2 m (4 ft) within the next
