Operation Manual

NO DECOMPRESSION LIMITS (NDLS)

Note how the No Decompression Limits for the ATMOS

are con-

trasted with the U.S. Navy limits (Fig. 93). The ATMOS

'S Dive

Planner does not scroll past 190 feet (57 meters), or to depths at

which projected dive time is less than one minute .

WARNINGS:

Using the ATMOS

, just as using the U.S. Navy (or

other) No Decompression Tables, is no guarantee of

avoiding decompression sickness (i.e., the bends).

AERIS advocates responsible diving practices . De-

compression diving is inherently hazardous and

greatly increases your risk of decompression sick-

ness - even when performed according to the

computer's calculations.

In the event that you must make an emergency de-

compression dive, you must not make another dive

for at least 24 hours.
