SUUNTO D6 - Manual (Page 62)

• The decompression range is the depth range between the ceiling and floor. Within
this range, decompression takes place. However, it is important to remember that
the decompression will be very slow at, or close to, the floor
The depth of the ceiling and floor will depend on your dive profile. The ceiling depth
will be fairly shallow when you enter the decompression mode, but if you remain at
depth, it will move downward and the ascent time will increase. Likewise, the floor and
ceiling may change upwards while you are decompressing.
When conditions are rough, it may be difficult to maintain a constant depth near the
surface. In such cases, it is more manageable to maintain an additional distance below
the ceiling, to make sure that the waves do not lift you above the ceiling. Suunto
recommends that decompression takes place deeper than 4 m/13 ft, even if the
indicated ceiling is shallower.
NOTE It will take more time and more air to decompress below the ceiling
than at the ceiling.
