ALGORITHM
The VEO is configured with 2 algorithms which allows you to choose which set of NDLs
(No Deco Limits) will be used for nitrogen/oxygen calculations and displays relating to
Plan and DTR (Dive Time Remaining).
You can select to use either the DSAT or the PZ+. 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, consid-
ered 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, No Deco Deep
and Safety Stops can be included for No Deco dives.
DEEP STOP (DS), No Deco only
When the DS selection is set On, it will trigger during No Deco dives when you descend
to 80 FT (24 M), then calculate (and continually update) a Stop Depth equal to 1/2 the
Max Depth.
While 10 FT (3 M) deeper than the calculated DS, you will be able to access a DS Pre-
view screen that will display the current DS Stop Depth/Time.
