PRE DIVE PLANNING SEQUENCE TM
The Pre Dive Planning Sequence (PDPS), which appears after
Surface Mode prior to the first dive of a new activation period,
provides a sequence of theoretical dive times available for
depths ranging from 30 FT (9 M) to 190 FT (57 M) in 10 FT (3
M) increments.
No decompression times (limits), or NDLs, are only displayed
for depths where there is at least 3 minutes of theoretical dive
time available at the depth, taking into account a descent rate of
60 feet (18 meters) per minute.
The PDPS should be reviewed prior to every dive to help you
plan your dive as required to avoid exceeding no decompres-
sion or oxygen exposure limits.
For repetitive dives, the PDPS indicates adjusted dive times that
are available for the next dive, based on residual nitrogen or
oxygen accumulation (whichever is in control) following the last
dive and surface interval. It appears after the SAT screen in the
scrolling Surface Sequence (SURF > FLY > SAT > PDPS).
WARNING: The available dive times provided are
only predictions, depending on cylinder size and air
consumption rate, you may have less time available
than indicated because of those and other factors.
