PRE DIVE PLAN MODE
NOTE: Genesis Scuba strongly recommends that you review the Plan
Mode prior to every dive to help you plan your dive as required to avoid
exceeding no decompression or oxygen exposure limits.
This is especially important for repetitive dives, when the Plan Mode
indicates adjusted no decompression limits available for your next dive
based on any residual nitrogen following your last dive and surface
interval.
WARNING: The Plan Mode predicts only no decompression times for
subsequent dives. Depending on cylinder size and air consumption you
may have less time available than indicated.
Plan Mode appears as part of the Surface Sequence (Surface Mode > Fly/DeSat > Plan).
With each Depth displayed in the Plan Mode, you will see 'predicted' no decompression limits
(NDL) based upon your previous dive profiles. The symbol NDL will be displayed (Fig. 16a)
with a sequence of theoretical dive times available for depths ranging from 30 feet (9 meters) to
190 feet (57 meters) in 10 foot (3 meter) increments.
No decompression times are only displayed for depths where there are at least 3 minutes of dive
time available at that depth, taking into account a descent rate of 60 feet (18 meters) per minute.
