warning
It is much more practical to stay within the 11 minutes of no-decompression
time allowed at 130 feet. If you exceed 160 feet, watch the Pro closely be-
cause you will enter decompression rapidly. The Tissue Loading Bar Graph
will alert you when entering decompression by entering the red zone (Fig. 25)
and changing dive time remaining from NDC to DEC. The Audible Alarm
(when activated) will also alert you when entering decompression with a
Double Beep.
EMERGENCY DECOMPRESSION
After entering decompression (especially at deeper depths) the Tissue
Loading Bar Graph may “fill” the 10, 20, 30 and 40 FT STOP decompression
zones rapidly. Once you’ve entered decompression, it is imperative that you
ascend toward the required decompression ceiling immediately. If you
continue the dive at a greater depth, your exposure to decompres-
sion sickness will increase, and you risk entering violation mode
and losing information needed to properly ascend.
Whether at 160 feet on a first dive, or 60 feet on a third dive, it is possible
to quickly enter decompression if you’re not careful. Decompression is to be
avoided because you cannot ascend directly to the surface without potentially
dire consequences. If your equipment failed, requiring you to surface imme-
diately, you would risk decompression sickness. Your buddy would be unable
to lend assistance without also risking decompression sickness. Decompres-
sion diving requires special training and equipment to do properly,
for these reasons decompression sport diving should be avoided.
