Consumed Bottom Time (Cbt) - Suunto Vyper User Manual

3.2.2. Consumed Bottom Time
(CBT)
The available no-decompression time is also shown
visually in the multi-function bar graph on the left
side of the display (Fig. 3.7, 3.8 and 3.9). When your
available no-decompression time decreases below
200 minutes, the fi rst (lowest) bar graph segment
appears. As your body absorbs more nitrogen, more
segments start to appear.
Green Zone - As a safety precaution SUUNTO
recommends that when using this dive computer
you should maintain the no-decompression bar graph
within the green zone. Segments start to appear when
the available no-decompression time decreases below
100, 80, 60, 50, 40, 30 and 20 minutes.
Yellow Zone- As the bars reach the yellow zone, your
no-decompression limit is less than 10 or 5 minutes
and you are getting very close to no-decompression
limits. At this point, you should start your ascent
towards the surface.
Red Zone - As all of the bars appear (red zone),
your no-decompression limit has become zero and
your dive has become a decompression dive (for
more information see section 3.2.5. "Decompres-
sion dives").
