Program Purpose

The Cavern Diver course offers the certified advanced open water diver a first glance into the truly mesmerizing world of underwater caverns.

The program is designed to develop cavern diving skills and to insure that divers are aware of self-responsibility and capable of risk management in the overhead environment.

As the first of three steps toward the full Cave Diver certification, this course will allow you to explore that portion of the cave system within the daylight zone. It will provide you with the opportunity to experience the overhead environment in a controlled setting to determine if cave diving is of interest to you.

Whether or not you decide to pursue additional cave training, the knowledge and experience gained during the Cavern Diver course will serve to greatly improve your open water diving skills and awareness.
