DCIEM Decompression Algorithm

Shearwater dive computers are capable of calculating decompression
stop requirements. These calculations are at best a guess of real
physiological decompression requirements. Even when following
computer directions exactly, there is a risk of decompression sickness
causing injury or death. Dives requiring staged decompression are
substantially riskier than dives that stay well within no-stop limits.
YOU REALLY ARE RISKING YOUR LIFE WITH THIS ACTIVITY.
DANGER
Shearwater computers have bugs. Although we haven’t found them all
yet, they are there. It is certain that there are things that our computers
do that either we didn’t think about, or planned for them 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.
Your 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).
