DIVE COMPUTER PERFORMANCE
• Algorithm - Pelagic Z+ and/or Pelagic DSAT.
• No Deco Limits - closely follow PADI RDP.
• Decompression - in agreement with Buhlmann ZHL-16c and French MN90.
• No Deco Deep Stops - Morroni, Bennett.
• Deco Stops (not recommended) - Blatteau, Gerth, Gutvik.
• Altitude - Buhlmann, IANTD, RDP (Cross).
• Altitude corrections and Oxygen limits - based on NOAA tables.
DUAL ALGORITHM
Most current Oceanic PDCs feature both the Pelagic Z+ and the DSAT algorithms, which
allows you to choose which set of NDLs (No Deco Limits) will be used for Ni/O2 calcula-
tions and displays relating to Plan and DTR (Dive Time Remaining).
DSAT* has been the standard used by Oceanic in all of its PDCs until this time. It features
NDLs that are based on exposures and test data which also formed validation for the PADI
RDP. Data consists primarily of No Deco, multi level, repetitive dives at sea level. It im-
poses restrictions for repetitive Deco dives, considered more risky.
Z+ performance is based on Buhlmann ZHL-16c. It affords an increase in conservatism
for No Deco multi level, repetitive dives at sea level. Data consists primarily of repetitive
Deco dives at altitude.
