DIVE COMPUTER LIMITATIONS
While the instrument is based on current decompression research and technology, the user/ diver must realize that the
computer cannot monitor the actual physiological functions of an individual diver. All decompression schedules currently
known to the authors, including the U.S. Navy Tables, are based on a theoretical mathematical model which is intended to serve
as a guide to reduce the probability of decompression sickness.
The mathematical model uses an ascent rate of 10 m/min [33 ft/min]. Therefore it is critical that a proper ascent rate is always
used.
The reader/diver is forewarned that individual physiological differences, severe environmental conditions and predive activi-
ties, especially those which tend to increase dehydration, may increase the risk of decompression sickness.
As a safety precaution Suunto recommends that divers using this instrument should maintain no less than 10 minutes no-
decompression time remaining at all times during the dive. This is especially important for divers in poor physical condition, in
cold water or other arduous conditions.
Historically divers have been advised to always include a margin of safety in their diving activities. Suunto supports these
practices and strongly recommends that the diver make the deepest portion of the dive near the beginning of the dive and
gradually progress into shallower depth, allowing time for a 3 to 5 minutes “safety stop” at a depth range of 3 to 6 meters (10
to 20 ft). This is believed to be effective in further reducing the risk of decompression sickness.
Furthermore, the reader/diver is advised that any dive carries some risk of decompression sickness and neither the authors, nor
SUUNTO Oyj will assume any responsibility or liability for accidents or injuries which might occur for any reason.
