profiles. The PDPS automatically replaces Surface Mode every minute.
Information provided includes depths and no-decompression dive times.
WARNING – The Pre Dive Planning Sequence predicts only no-
decompression times for subsequent dives. Depending on tank size
and air consumption, you may have
less time available
than shown
in the PDPS because of air limitations.
PDPS no-decompression times are displayed only for depths where there
is at least one minute available. This takes into account a descent rate of 75
feet per minute. Before a “clean” dive (no dives in 24 hours), the PDPS no-
decompression limits are those found on page 54 in the Reference section.
NO-DECOMPRESSION DIVE MODE
No-decompression Dive Mode, identified by the No Decompression Icon
to the left of the Time Display (Fig. 11a), appears when the diver descends
deeper than five feet. Information provided includes current depth, elapsed
dive time (and Elapsed Dive Time Icon-Fig. 11b), no-decompression dive time
remaining, and maximum depth for this dive (and Max Depth Icon-Fig. 11c).
The Graphic Diver Interface is also active, displaying nitrogen loading
(TLBG) and ascent rate (VARI).
