The Technical Diving International (TDI) Full Cave Diver program consists of three sections: Cavern Diver, Intro to Cave, and Full Cave Diver.

This course is the third stage of training in the series of TDI’s Cave Diver development program. Advanced cave dive planning, the practical execution of different types of cave systems and scenarios divers encounter are presented.
