FOR CERTIFIED SCUBA INSTRUCTION, including training in the principles of
decompression.
1.1.1. Emergency Ascents
In the unlikely event that the dive computer malfunctions during a dive, follow the
emergency procedures provided by your certied dive training agency or, alternatively,
STEP 1: Assess the situation calmly and then move promptly to less than 18 m [60 ft].
STEP 2: At 18 m [60 ft], slow down your ascent rate to 10 m/min [33 ft/min] and move
to a depth between 3 and 6 meters [10 to 20 ft].
STEP 3: Stay there as long as you assess your air supply will safely allow. After
reaching the surface stay out of the water for at least 24 hours.
1.1.2. Dive Computer Limitations
While the dive computer is based on current decompression research and technology,
you must realize that the computer cannot monitor the actual physiological functions
of an individual diver. All decompression schedules currently known to the authors,
including the U.S. Navy Tables, are based on theoretical mathematical models, which
are intended to serve as a guide to reduce the probability of decompression illness.
