Information provided includes Current Depth, Elapsed Dive Time (and Elapsed
Dive Time icon), No Decompression Dive Time Remaining for that depth, and
Maximum Depth for that dive (and Max Depth icon). The Graphic Diver Inter-
face is also active, displaying nitrogen loading (TLBG) and ascent rate (VARI).
No Decompression Dive Time Remaining is the maximum amount of
time you can stay at your current depth before entering a decompression
situation. The No Decompression Time is calculated based on the amount
of nitrogen absorbed by 12 hypothetical tissue compartments. The rates
each of these compartments absorb and release nitrogen is mathemati-
cally modeled and compared against a maximum allowable nitrogen level.
Whichever one of the 12 is closest to this maximum level will be consid-
ered the controlling compartment for that depth. Its resulting value is
displayed numerically (Fig. 22a) along with the No Decompression Dive
icon (Fig. 22b), and graphically in the TLBG (Fig. 22c).
As you ascend from depth following a dive that has approached the no
decompression limit, the TLBG will diminish as control shifts to slower
compartments. This is a feature of the decompression model that is the
basis for multilevel diving, one of the most important advantages the
Data100 offers. See page 62 in the Reference section for more information
pertaining to tissue tracking.
