DECOMPRESSION VIOLATION LIMITS

As described on pages 28 – 33, the DataMax Sport has two permanent

violation modes that will result in the loss of some computer functions if
entered.  These are termed, 

Delayed and Immediate Violation Modes.  Figure

38 shows a chart which details where those limits occur on extreme dive
profiles between 160 and 190 feet on a first dive.  The chart is meant as a
reference and not a suggestion for planning a dive.

It is possible to exceed these limits at much shallower depths, especially

on repetitive dives.  Watch the DataMax Sport closely to avoid entering
decompression, or entering a violation mode.

WARNING – Oceanic recommends that you follow the rules of
responsible diving on every dive, and strongly recommends against
decompression diving, or diving below 130 feet.

CONCLUSION

The DataMax Sport will provide you with information to help plan your

dives, make mid-dive decisions, and enjoy more fun time underwater.  How-
ever, it is only an informational tool whose entire worth depends on using it
correctly.  The DataMax Sport can greatly add to your enjoyment of the
underwater world.  Learn how to use it.  Use it wisely.  And have fun with
the DataMax Sport, your guide to the Oceanic frontier.
