3.3.4. CONSUMED BOTTOM TIME (CBT)

The available no-decompression stop 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 first

(lowest) bar graph segment appears. As your body absorbs more nitrogen,

more segments start to appear.

Green Zone - As a safety precaution Suunto recommends 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 stop

time 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 stop

time has become zero and your dive has become a decompression stop dive

(for more information see section 3.3.6. "Decompression dives").

The ascent rate is shown graphically along the right side of the display as

follows:
