Maybe you’re one of those nerds who wants to understand how a
regulator works even before you try diving for the first time. Maybe
you’ve been diving for a long time, but somehow you sometimes feel like
you really don’t know enough about what you’re doing. Maybe you want to
become a diving instructor and wonder if you already know enough.
All this and much more are good reasons for the Science of Diving
course. The SSI course is a prerequisite for the SSI Divemaster, it
provides all the basic information in a compact and complete way.
