7. AFTER DIVING

Once back at the surface, Suunto Cobra3 continues to provide 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 O2%

•the oxygen partial pressure labeled PO2

•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 Cobra3 includes a dive planner that allows you to review the no-decompression limits on a subsequent dive, taking the residual nitrogen loading of previous dives into consideration. The Dive Planning mode is explained in Section 7.5.1. Dive Planning mode (PLANnodec).
