NO DECOMPRESSION LIMITS
The no-decompression limits for the DataMax Sport are contrasted with
the U.S. Navy limits at left (Fig. 36). You will notice that at all but three
depths, the DataMax Sport allows less time than the U.S. Navy Tables.
Though the DataMax Sport 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 DataMax Sport?” 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 DataMax
Sport. In this example, the Sport 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
DataMax Sport was taken to the next shallower depth. This continued until
33 feet, 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.
