• The oor is the deepest depth at which the decompression stop time will not
increase. Decompression will start when you pass this depth during your ascent.
• The decompression range is the depth range between the ceiling and oor.
Within this range, decompression takes place. However, it is important to remem-
ber that the decompression will be very slow at, or close to, the oor.
The depth of the ceiling and oor will depend on your dive prole. 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 oor and
ceiling may change upwards while you are decompressing.
When conditions are rough, it may be difcult to maintain a constant depth near the
surface. In this case it will be 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.
