NO DECOMPRESSION LIMITS
The no-decompression limits for the PRODIGY are contrasted with the
U.S. Navy limits in Fig. 36. You will notice that at all but three depths, the
PRODIGY allows less time than the U.S. Navy Tables. Though the
PRODIGY no-decompression limits may be less than the U.S. Navy, you will
receive greatly increased bottom times if you follow a multi-level dive profile;
sometimes two or three times, as much bottom time!
MAXIMUM NO-DECOMPRESSION DIVE PROFILE
Many people ask, “Just how deep can I go, and how long can I stay, with
the PRODIGY?” The answer depends on many factors including air supply,
previous dives made, etc. Assume for a minute that no previous dives were
made, and that the diver had an unlimited air supply. Figure 37 shows a
maximum no-decompression dive profile that is possible with the PRODIGY.
In this example, the PRODIGY was taken to a depth where the No-decom-
pression Dive Time Remaining reached three minutes. It was then taken to a
shallower depth where it received one minute of no-decompression time
credit. When the no-decompression time neared zero at this new depth, the
PRODIGY was taken to the next shallower depth. This continued until 33
feet (10 meters), where there was obviously more no-decompression time
available than possible air time with even the largest scuba tank. A safety
stop was added as a precaution to round out this simulated dive.
