The
Decompression Procedures Manual is the text-book literary assistant to
the TDI Decompression Procedures certification course. TDI has brought
this course to the recreational diver in response to the demand and
desire for more information. The Decompression Procedures course is
available to two classes of divers. Recreational divers can take the
course to develop new skills and understanding. Recreational-Technical
divers can take the course during the series of courses available
through TDI, usually between Advanced Nitrox and Extended Range and
Trimix.
