SDI, or Scuba Diving International, offers unique advantages to new scuba divers because of its roots in TDI, or Technical Diving International. Unlike other agencies, SDI promotes flexibility in equipment and techniques, ensuring that divers can use the gear they will actually be diving with. This agency also emphasizes a real-world approach, teaching skills relevant to their diving environments. Lastly, SDI champions innovation, providing eLearning options and programs tailored for younger divers, making scuba diving accessible to more people.
