Decompression Diving
Description
The depth and time limits of Recreational diving
are generally considered to be 40 metres and within
the no-decompression limits of the dive tables.
However many divers are venturing well beyond these
limits, or would like to. The aim of the SSI
Decompression diving program is to provide the
necessary information and training to safely
conduct dives beyond the generally accepted
recreational limits. It is not the intention of
this program to set anyone's limits or to
encourage diving to great depths.
