Oceanic Personal Dive Computer Algorithm
Decompression theory can be trusted only as far as it has been demonstrated by actual test dive data. In 1987 a unique series of experiments were conducted by Diving Science and Technology (DSAT). Commissioned by the Professional Association of Diving Instructors (PADI), these Doppler ultrasound monitored human experiments conducted by Dr. Michael Powell produced the most comprehensive data set that exists for recreational divers to this day. These data were used to validate the PADI Recreational Dive Planner and are the basis of the algorithm used in all Oceanic Personal Dive Computers (PDCs).

Patent Pending Nitrogen Tissue Loading Bar Graph Adjustment allows you to select the personal degree of conservatism you wish to build into each dive. An audible alarm alerts you when the bar graph has reached your maximum desired set point. (all models exept Veo 100/150)

"The ultimate adjustable algorithm." That's the way divers, instructors and Oceanic Dealers refer to Oceanic PDCs. Our trademark bar graphs provide complete control of your margin of safety for each dive. Want to be a bit more cautious? Make it a personal rule to never enter into the caution zone, or stay one pixel away, or – you get the point. Now you can even program several of our PDCs to do it for you with our patent pending Nitrogen Bar Graph Alarm; set it once and let your computer alert you when your bar graph reaches that level.

*Battery Life: Battery life estimates are based on full-capacity batteries, and continuous usage as described.

- Backlight set on continously throughout dive

- 7 days per week

- 2 dives per day

- 1 hour dive time

- 2 hour surface interval

- 18 hour interval from last dive to the first of the next day

* The DataMask HUD Transmitter consumes little or no battery power when inactive, or not pressurized. For purposes of this specification, use life is based on continuous use, 24 hours a day, 7 days a week.

** Oceanic Personal Dive Computers have user selectable Sampling Rates that determine when data is sampled and stored for subsequent download to associated PC interface programs. More frequent sampling provides more data per dive yet results in storage of fewer dives for download. Use with Air or Nitrox, with or without air integration, dive profiles, Free Diving activities, and other variables may also affect the number of dives that can be stored.
