SDI is the fastest growing recreational certification agency in the world. Courses range from kids snorkeling programs, through Open Water instructor, taught in over 15 languages.

Scuba Diving International (SDI) is the recreational arm of Technical Diving International, the world’s largest technical diver training organization.

Among the things that make SDI different:

  • SDI believes that training should reflect the equipment technology real-world divers actually use, and the procedures they actually follow.
  • SDI training reflects not only our unparalleled experience in technical diving, but also our extensive experience as dive store and resort operators, and dive boat captains.
  • SDI also embraces the latest technology to make learning dive as easy and enjoyable as possible.

SDI was the first diver training organization that made it possible for entry-level students to complete all of their academic training on line. SDI is the only organization that requires its stores and instructors to make personal dive computers available to students on all training dives.
