Consumed Bottom Time (CBT)3.3.3.

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. and 3.8.). 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.

White 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 3.3.5. “Decompression dives”).

Ascent Rate Indicator3.3.4.

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

lows:
