Data Plus 2
NO DECOMPRESSION LIMITS
Note how the No Decompression Limits for the Data Plus 2 are
contrasted with the U.S. Navy limits (Fig. 73). For most depths,
the Data Plus 2 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 bot-
tom times as you take advantage of the multilevel dive capabilities
offered by the Data Plus 2. Notice also that the Data Plus 2 Pre
Dive Planning Sequence does not scroll past 160 feet (48 meters).
DECOMPRESSION MODEL
The decompression model used by the Data Plus 2 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, Data Plus 2 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.
