This course develops the minimum skills and knowledge for cavern diving, and describes the dangers involved with cave diving. Planning, environment, procedures, techniques, problem solving, and other specialized needs of cavern diving are covered.

Problem solving in cavern diving includes, but is not limited to: body positioning (trim), buoyancy control, emergency procedures, line following, and propulsion techniques.

Accident analysis forms the basis of this learning experience. Special emphasis on the unique environment includes silting, entanglement, disorientation, and equipment modifications.

The Cavern Diver Course is in no way intended to provide instruction for cave diving. This course level is an entry-level program for those interested in cave diving, and is also a safety program for open water divers. It can be combined with the Basic Cave Diver course.
