SUUNTO SPYDER - Manual (Page 83)

treat the next dive as a continuation of the previous dive. It adds the dive times,
and calculates no-decompression limits or decompression stops based on excess
nitrogen absorbed on both dives. In this regard, it is similar to the U.S. Navy
tables.
Depth Limits
WARNING!
SUUNTO STRONGLY RECOMMENDS THAT SPORT DIVERS LIMIT THEIR
MAXIMUM DEPTH TO 40 m [130 ft]! Exposure to greater depth increases the
risk of decompression sickness.
However, the Spyder will calculate at greater depths to provide a wide margin of
flexibility if, through carelessness or emergency, you exceed this recommended
depth limit for a dive.
