Overhead Environments
Divers love to explore and while most divers are content to confine their diving to the open water, allowing direct access to the surface at all times, others love the thrill of discovering new places far from the surface. Undersea caves, abandoned mines, under the ice and inside shipwrecks are all popular destinations for these intrepid explorers who go beyond the bounds of recreational diving.
If this type of exploration appeals to you, then NAUI training programs for overhead environments is for you! Take a look at the list of NAUI programs and contact your local NAUI Instructor for additional information.
Cavern Diver
The NAUI Cavern Diver course provides you with the fundamental skills and knowledge needed for cavern diving at depths not exceeding 100 fsw (30 msw) and at a combined depth and distance penetration not exceeding 200 feet (61 meters) from the surface. Participants will become proficient in the use of lines reels while handling a light, team and line placement, zero visibility/touch contact communications while following a line, as well as many other skills that are necessary to be a competent Cavern Diver.
Cave Diver (Levels I & II)
Does the thought of diving through an underwater cave intrigue you? Are you fascinated by the possibility of diving where few divers go? The NAUI Cave Diver Levels I and II courses build on skills and knowledge taught in the Cavern Diver course. Upon successful completion of the NAUI Cave Diver Level I course, you are qualified to plan and execute limited-penetration, simple navigation, no-decompression cave dives to depths that do not exceed 100 fsw (30 msw). NAUI Cave Diver Level II are qualified to plan and execute longer penetration cave dives with staged cylinders involving complex navigation to depths that do not exceed 130 fsw (40 msw).
Cave Guide (Technical Support Leader)
The NAUI Cave Guide course provides you with the skills and knowledge needed to plan and execute guided tours in caverns and caves. As a Cave Guide, your responsibilities might include escorting stressed diver(s) out of a cave system, repairing broken guide lines, as well as assuring that all guided divers are out of the cave after completion of a dive.
Wreck Penetration Diver
The NAUI Wreck Penetration Diver course provides you with the skills and knowledge needed to minimize risks in penetration wreck diving at depths not exceeding 130 fsw (40 msw). Wreck penetration diving is any diving inside a sunken vessel, aircraft, or similar structure. Learn about the safety hazards and special risks of overhead environments, gas management, entanglement, limited visibility, NAUI Technical Equipment Configuration (NTEC), specialized equipment utilized in wreck penetration diving, search methods, underwater navigation, legal aspects, artifacts, treasure, salvage, archaeology, and more.
Technical Wreck Penetration Diver
The NAUI Technical Wreck Penetration Diver course is a combination of technical diving and wreck exploration. This course provides you with the skills and knowledge needed to minimize risks in penetration wreck diving at depths beyond 130 fsw (40 msw) and utilize trimix for dives to depths not exceeding 180 fsw (55 msw) that require staged-decompression, utilizing EANx mixtures and/or oxygen during decompression.
Technical Ice Diver
The NAUI Technical Ice Diver course provides a basic understanding of the knowledge and skills needed to minimize risks of diving under ice. Upon successful completion of the NAUI Technical Ice Diver course, you are qualified to plan and execute ice dives that do not require staged-decompression. Training includes a minimum of three open water dives limited to a maximum depth of 40 feet (12 meters) and not more than 100 feet (30 meters) in a horizontal line from the penetration hole.
Mine Diver (Levels I and II)
Mine divers explore abandoned and flooded mine shafts left from bygone days when a particular site was an active mining operation. The NAUI Mine Diver Level I and Level II courses teaches the specific skills and knowledge needed to gain experience and minimize risk during mine diving operations. Level I Mine Divers are qualified to penetrate to a maximum depth of 100 feet (30 meters) with simple navigation while observing no-decompression limits. Level II Mine Divers are qualified to plan and execute longer penetration mine dives with staged cylinders involving complex navigation to depths that do not exceed 130 feet (40 meters).
