INTRO TO CAVE CERTIFICATE

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 an introduction to the basic principles of cave diving utilizing a single primary guide line. Introductory cave diving is the second level in the development of safe techniques for cave diving, directly building upon the cavern diver course. This introduction to cave diving is not intended to train divers for all facets of cave diving. The objective of this course is the perfection of skills taught in the cavern diving program, in addition to the adoption of additional techniques and procedures required for elementary cave dives.
