This computer has bugs. Although we haven’t found them all yet,
they are there. It is certain that there are things that this computer
does that either we didn’t think about, or planned for it to do
something different. Never risk your life on only one source of
information. Use a second computer or tables. If you choose to
make riskier dives, obtain the proper training and work up to them
slowly to gain experience.
This computer will fail. It is not whether it will fail but when it will
fail. Do not depend on it. Always have a plan for how to handle
failures. Automatic systems are no substitute for knowledge and
training.
No technology will keep you alive. Knowledge, skill, and practiced
procedures are your best defense (except for not doing the dive, of
course).
WARNING
This computer is capable of calculating deco stop requirements. These
calculations are at best a guess of real physiological decompression
requirements. Dives requiring staged decompression are substantially
more risky than dives that stay well within no-stop limits.
Diving with rebreathers and/or diving mixed gases and/or performing
staged decompression dives and/or diving in overhead environments
greatly increases the risk associated with scuba diving.
YOU REALLY ARE RISKING YOUR LIFE
WITH THIS ACTIVITY.
