ALGORITHM (NDL Basis)
The OC1 is configured with 2 algorithms which allows you to choose which set of NDLs
(No Deco Limits) will be used for Ni/O2 calculations and displays relating to Plan and
DTR (Dive Time Remaining).
You can select DSAT or PZ+ as the NDL Basis. The selection will lock in for 24 hours after
the last dive.
DSAT has been the standard used by Oceanic in all of its dive computers until this time. It
features NDLs that are based on exposures and test data which also formed validation for
the PADI RDP. It imposes restrictions for repetitive Deco dives, considered more risky.
PZ+ (Pelagic Z+) performance is based on Buhlmann ZHL-16c. It features NDLs that are
considerably more conservative especially at shallower depths.
To create even greater margins of safety with respect to decompression, a Conservative
Factor as well as No Deco Deep and Safety Stops can be included for No Deco dives.
