WARNING
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 on 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)�
DANGER
This computer is capable of calculating deco stop requirements� These calculations are
at best a guess of the 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 of scuba diving�
You really are risking your life with this activity�
