Cavern and Cave Diving


NAUI Cavern Course


Cavern Diver is a no-decompression course designed to teach you the fundamental skills and knowledge for cavern diving above 100 fsw / 30 msw and at a combined depth and distance penetration less than 200 feet / 60 meters from the surface.

During your course, you will complete a minimum of three cavern dives in at least two different sites within daylight and no-decompression limits, and become proficient in the use of spools and reels, team and line placement, and zero visibility/touch contact communications while following a line, as well as many other skills necessary to be a competent Cavern Diver.

Dive planning (including EANx if used) penetration distance within cavern diver limits, safety drills, equipment checks, gas sharing, guideline deployment and removal techniques, propulsion techniques, lost teammate and guideline drills and emergency procedures will also be covered in your Cavern Diver course.

NAUI Cave Course


Does the thought of diving through an underwater cave intrigue you? Are you fascinated by the possibility of diving where most divers never get to go? Cave Diver Levels I, II and III are actually three courses, each of which builds on skills and knowledge taught in the Cavern Diver course and/or respective previous level Cave Diver courses, giving you the next level of skills and experience you need to become a certified Level I, II or III Cave Diver.

Once you complete your Level I Cave Diver course, you will be able to plan and execute limited penetration, simple-navigation no decompression cave dives; certified Level II Cave Divers are qualified to plan and execute multiple navigational decisions on cave dives with staged cylinders; certified Level III Cave Divers are qualified to plan and execute extended penetration cave dives.

If you’re 18 years old and at least a NAUI Advanced Scuba Diver and Nitrox Diver with 75 logged dives, you may be ready for the challenge of cave diving!
