PRE DIVE PLANNING SEQUENCETM
Oceanic strongly recommends that you review the Pre Dive Planning Sequence (PDPS) 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 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.
The PDPS provides 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.
During the sequence, no decompression times 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 and ascent rates of 60 feet (18 meters) per minute.
