Suunto Cobra3 [30/60] Ceiling ceiling zone floor and decompression range

NOTE
In addition, there may also be Mandatory Safety Stops which are not
displayed in ASC TIME.
WARNING
YOUR ACTUAL ASCENT TIME MAY BE LONGER THAN
DISPLAYED BY THE INSTRUMENT! The ascent time will increase
if you:
•
remain at depth
•
ascend slower than 10 m/33 ft per minute
•
make your decompression stop deeper than at the ceiling
These factors will also increase the amount of air required to reach
the surface.
Ceiling, ceiling zone, floor and decompression range
When in decompression, it is important that you understand the meaning of ceiling, floor,
and decompression range.
•
The ceiling is the shallowest depth to which you should ascend when in decompression.
At this depth, or below, you must perform all stops
•
The ceiling zone is the optimum decompression stop zone. It is the zone between the
minimum ceiling and 1.2 m/4 ft below the minimum ceiling
•
The floor is the deepest depth at which the decompression stop time will not increase.
Decompression will start when you pass this depth during your ascent
•
The decompression range is the depth range between the ceiling and floor. Within this
range, decompression takes place. However, it is important to remember that the
decompression will be very slow at, or close to, the floor
The depth of the ceiling and floor will depend on your dive profile. 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 ascent time will increase. Likewise, the floor and ceiling may
change upwards while you are decompressing.
When conditions are rough, it may be difficult to maintain a constant depth near the surface.
In such cases, it is 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.
WARNING
NEVER ASCEND ABOVE THE CEILING! You must not ascend above
the ceiling during your decompression. In order to avoid doing so by
accident, you should stay somewhat below the ceiling.
Display below the floor
The blinking ASC TIME and an upward pointing arrow indicate that you are below the
floor. You should start your ascent immediately. The ceiling depth is shown on the left
side, and the minimum total ascent time on the right side, of the center window. Below is
an example of a decompression dive without Deep Stops, below the floor.

- Declination you can compensate for the difference between true north and magnetic north by adjusting the compass declination the declination can be found for example from sea charts or topographic maps of the local area 15
- If the calibration fails several times in a row it is possible that you are in an area with sources of magnetism such as large metal objects power lines or electric appliances move to another location and try to calibrate the compass again if the calibration continues to fail contact an authorized suunto service center 15
- Time out 15
- Time out you can set the compass time out to 1 3 or 5 minutes after the set time has passed from the latest button press the dive computer returns to the time or dive mode from the compass mode 15
