A technical diving training agency founded in 1994, whose overhead programme runs from Cavern Diver through Intro to Cave and Full Cave, with stage, scooter, survey and rebreather cave options.
Technical Diving International (TDI) describes itself as having been founded in 1994, with its sister agencies Scuba Diving International (SDI) following in 1998 and Emergency Response Diving International (ERDI) and Performance Freediving International (PFI) in 2000 [1]. Its own history page gives two different counts for its international offices, so this reference does not quote one.
TDI's cave programme is a staged sequence. Cavern Diver is the entry course and is explicitly not intended to teach cave diving; Intro to Cave Diver is the second level; Full Cave Diver is described by TDI as the third stage of what it calls its Full Cave Diver Development Program [2][3][4]. TDI's course catalogue also lists Stage Cave Diver, DPV Cave Diver, Cave Surveying Diver and rebreather versions of the cavern, intro and full cave courses [5]. The public course pages state prerequisites and post-certification limits; the full standards are referenced separately.

Graduates may dive single-guideline caves without direct supervision within the published limits.As published: penetration by the rule of thirds, or one-sixth when using doubles; maximum depth 40 m; continuous guideline; planned dives must not exceed current certification and should approximate training.
