Suunto D9 Watch User Manual


 
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 willmove downwardand theascent timewill increase.Likewise, thefloor 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 suchcases, itis moremanageable tomaintain an additionaldistance 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 takemore timeand moreair todecompress below theceiling
than at the ceiling.
WARNING
NEVER ASCEND ABOVE THE CEILING! You must not ascend
above the ceiling during your decompression. In order to avoid
doing so byaccident, you shouldstay somewhat belowthe ceiling.
