VERSA
TISSUE LOADING BAR GRAPH (TLBG)
The TLBG (Fig. 2a) represents tissue loading of nitrogen,
showing your relative no decompression or decompression
status. As your depth and elapsed dive time increase, seg-
ments add to the TLBG, and as you ascend to shallower
depths, they will begin to recede, indicating that additional
no decompression time is allowed for multilevel diving.
The TLBG monitors 12 different nitrogen compartments simul-
taneously and displays the one that is in control of your dive.
It is divided into a green No Decompression (normal) zone,
a yellow Caution zone (also No Decompression), and a red
Decompression (danger) zone.
VARIABLE ASCENT RATE INDICATOR (VARI)
The VARI (Fig. 2b) provides a visual representation of ascent
speed (i.e., an ascent speedometer).
• Green is a 'normal' rate, yellow a 'caution' rate, and red
is 'Too Fast'.
• The segments of the VARI represent two sets of speeds
which change at a reference depth of 60 feet (18
meters). Refer to the chart for segment values.
• At depths greater than 60 feet (18 meters), the VARI will
flash as a warning when an ascent exceeds 60 fpm (18
mpm). At depths of 60 feet (18 meters) and shallower, it
will flash if the ascent rate exceeds 30 fpm (9mpm).
