3.10. Decompression dives
When on a decompression (deco) dive you exceed the no-decompression limit, Suunto D5
provides the decompression information required for ascent. Ascent information is always
presented with two values:
•
Ceiling: depth that you should not go above
•
Asc. time: optimum ascent time in minutes to surface with given gases
WARNING: NEVER ASCEND ABOVE THE CEILING! You must not ascend above the
ceiling during your decompression. In order to avoid doing so by accident, you should stay
somewhat below the ceiling.
WARNING: When diving with multiple gases, remember that the ascent time is always
calculated with the assumption that you use all the gases found in the Gases menu. Always
check that you have only the gases for your current planned dive
defined before you dive.
Remove the gases that are not available for the dive.
On a decompression dive, there could be three kinds of stops:
•
Safety stop: this is a recommended three-minute stop for every dive over 10 meters (32.8
ft).
•
Deep stop: this is a recommended stop when you dive deeper than 20 m (65.6 ft).
•
Decompression stop: this is a compulsory stop on your decompression dive that is for
your safety, preventing decompressions sickness.
In Dive settings » Parameters, you can
•
turn deep stops on or
o (it is on by default)
•
adjust the safety stop time to be 3, 4 or 5 minutes (default is 3 minutes)
•
set last stop depth to 3.0 m or 6.0 m (default is 3.0 m)
The following illustration shows a decompression dive where the ceiling is at 17.7 m (58 ft):
