Note how the No Decompression Limits for the DataPlus are
60
contrasted with the U.S. Navy limits (Fig. 80). For most depths,
50
the DataPlus provides somewhat less no decompression times than
40
the U.S. Navy Tables. However, while the no decompression limits
30
25
may be less, you will receive greatly increased allowable bottom
20
times as you take advantage of the multilevel dive capabilities
15
offered by the DataPlus. Notice also that the DataPlus' PDPS does
10
not scroll past 160 feet (48 meters).

REPETITIVE DECOMPRESSION DIVING

The decompression model used by the DataPlus 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
Decompression dives. Due to the present unavailability of statisti-
cal data, DataPlus decompression predictions are based on U.S.
