PRE DIVE PLANNER
The Pre Dive Planner, 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 1 minute of theoretical dive
time available at the depth, taking into account a descent rate of
60 feet (18 meters) per minute.
The Planner 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 Planner 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 > PLAN).
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.
