made up of two bar graphs that have green, yellow and red markers to
indicate normal, caution, and danger zones, respectively. The two graphic
displays represent ascent rate and nitrogen loading.
When underwater, you can make quick status checks by glancing at the
two bar graphs and making sure that they are “in the green.” With one
quick glance you can make sure you’re not getting too close to the no-decom-
pression limit or ascending too fast.
ASCENDING TO THE SURFACE
A graphic representation of nitrogen absorption can be seen in the
“Tissue Loading Bar Graph” (Fig 3a). This green, yellow, red bar graph
shows how close you are to the no-decompression limit. It “fills–up” with
segments as your depth and bottom time increase, simulating the absorption
of nitrogen. Upon ascent to shallower depths, the Tissue Loading Bar Graph
will begin to recede giving a visual representation of nitrogen off–gassing.
The TLBG also provides a way to easily manage decompression by indicating
four red
“ceiling” depths. This is discussed fully in the “Handling the
Extremes” section beginning page 26.
When rising towards the surface, the
“Variable Ascent Rate Indicator
™
”
(Fig. 3b) shows how fast you are ascending. The VARI will alert you with a
flashing display if you enter the red zone, which represents ascent rates over
60 feet per minute. Immediately slow your ascent whenever this is seen.
