단체 개요 / Overview

• PADI (Professional Association of Diving Instructors) is the world's largest recreational scuba training agency, founded in 1966 by John Cronin and Ralph Erickson. It is estimated to account for roughly 60–75% of all certifications worldwide. [verified — Wikipedia/PADI]
• As a member of the US RSTC, its major courses are aligned with standards such as ISO 24801-1/-2, and it has a history of EUF certification. Its strengths lie in standardization, course materials, and brand recognition. [verified — Wikipedia]

• It is a de facto common language that works anywhere in the world simply by saying "PADI." It is also the most widely recognized agency at Korean fun-diving sites. [verified]
