Both students and instructors have embraced the no nonsense approach that
the SDI training system offers. They have streamlined the course materials
to let students study the essential academics with a renewed emphasis on
practical diving skills learned in both the pool and open water
environments. And SDI was the first agency to require students be taught
with modern dive computers from the outset.
SDI's course materials reflect the state-of-the-art in modern texts, for
example, the Open Water manual is a four color perfect bound set of books
lavishly illustrated with photography and graphics.
Diving is constantly changing. SDI's staff is looking ahead and strives to
continue their path as the innovators of the industry. They want to make the
experience of diving one that is enjoyed by every family member to the
fullest. At SDI, everyone is a diver and wants to share their love of the
sport with as wide an audience as possible.
