NO DECOMPRESSION LIMITS

Note how the No Decompression Limits for the XP 5 are
contrasted with the U.S. Navy limits (Fig. 97).  The XP 5
Dive Planner does not scroll past 160 feet (48 meters), or
to depths at which projected dive time is less than one
minute (unless Plan Mode is set for the Extended Range of
330 feet/99 meters) .

WARNING:  Using the XP 5, just as using the U.S.
Navy (or other) No Decompression Tables, is
no guarantee of avoiding decompression
sickness (i.e., the bends).

WARNING:  SEEMANN advocates responsible
diving practices .  Decompression diving is
inherently hazardous and greatly increases
your risk of decompression 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.
