In 1998 the membership of TDI could no longer be held back from the demand to create a sport diving division of TDI and thus was born Scuba Diving International (SDI). The primary reason for this expansion was that dive instructors valued dealing with an agency that listened to the instructors in the field and created programs that were, and continue to be, very popular because they are tailored to the way today’s diver wants to learn to dive.
