NO DECOMPRESSION LIMITS

Note how the No Decompression Limits for the Pro Plus are con-
trasted with the U.S. Navy limits (Fig. 81).  For most depths, the
Pro Plus 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 of-
fered by the Pro Plus.  Notice also that the Pro Plus Pre Dive Plan-
ning Sequence does not scroll past 160 feet (48 meters).

DECOMPRESSION MODEL

The decompression model used by the Pro Plus is based on the no
decompression multilevel repetitive dive schedules successfully
tested by Dr. Ray Rogers and Dr. Michael Powell.  These tests did
not include repetitive dives deeper than 90 feet (27 meters) or de-
compression dives.

Due to the present unavailability of statistical data, Pro Plus de-
compression predictions are based on U.S. Navy theory.  Therefore,
pay special attention to the Warnings  and Safety Recommenda-
tions that have been provided in this owner's guide.
