7. AFTER DIVING
Once back at thesurface, Suunto Cobra3 continues toprovide post-dive safety information
and alarms. Calculations to enable repetitive dive planning also help to maximize diver
safety.

7.1. Surface interval
An ascent to any depth shallower than 1.2 m/4 ft will cause the DIVING display to be
replaced by the SURFACE display:
IT IS 15 MINUTES SINCE YOU SURFACED
FROM A 6-MINUTE DIVE. THE PRESENT DEPTH IS
0.0 M. THE AIRPLANE SYMBOL AND NO-FLY VALUE
INDICATE THAT YOU SHOULD NOT FLY FOR 20
HOURS.
Or, in the alternative displays, the following information will be shown:
•
maximum depth of last dive in meters/feet
•
dive time of last dive in minutes, shown as DIVE TIME
•
the current time, shown as TIME
•
the current temperature in °C/°F
•
tank pressure
If set to NITROX mode, the following information will also be shown:
•
the oxygen percentage labeled O
2
%
•
the oxygen partial pressure labeled PO
2
•
the current oxygen toxicity exposure labeled OLF
7.2. Dive numbering
Several repetitive dives are considered to belong to the same repetitive dive series when
the dive computer has not counted the no-fly time to zero. Within each series, the dives
are given individual numbers. The first dive of the series will be numbered as DIVE 1, the
second as DIVE 2, the third as DIVE 3, etc.
If you start a new dive with less than 5 minutes of surface interval time, the dive computer
interprets this as a continuation of the previous dive and the dives are considered to be
the same. The diving display will return, the dive number will remain unchanged, and the
dive time will begin where it left off. After 5 minutes on the surface, subsequent dives are,
by definition, repetitive. The dive counter displayed in the Planning mode will increment
to the next number if another dive is made.
7.3. Repetitive dive planning
The Suunto Cobra3includes a dive plannerthat allows you toreview the no-decompression
limits on a subsequent dive, taking the residual nitrogen loading of previous dives into
consideration. The Dive Planning modeis explained in Section 7.5.1. Dive Planningmode
(PLANnodec).
