NO DECOMPRESSION LIMITS
Note how the No Decompression Limits for the 500AI are contrasted with the
U.S. Navy limits (Fig. 85). For most depths, the 500AI provides somewhat less
no decompression times than the U.S. Navy Tables. However, while the No
Decompression Limits may be less, you will receive greatly increased allowable
bottom times as you take advantage of the multilevel dive capabilities offered
by the 500AI. Notice also that the 500AI Planning Sequence does not scroll
past 160 feet (48 meters).
WARNING: Using the 500AI, just as using the U.S. Navy (or
other) No Decompression Tables, is no guarantee of avoiding
decompression sickness, i.e. “the bends.”
WARNING: AERIS advocates responsible diving practices and
does not recommend decompression diving, or diving below 130
feet (39 meters). The decompression capabilities of the 500AI
are intended strictly for emergency use. Decompression diving
is inherently hazardous and greatly increases your risk of de-
compression sickness - even when performed according to the
computer's calculations. In the event that you must make an
emergency decompression dive, you must not make another
dive for at least 24 hours.
