Cavern Course

Explore secrets hidden in Caverns around the world and gain the knowledge, experience and skills to do it correctly and safely.


_DSC2146Cavern diving is an opportunity for divers to experience the thrills of Cave diving whilst staying within close proximity to the entrance of a cave, within the ‘light zone’ and open water at all times.

One of the most beautiful and exciting places to dive underwater is in a cavern. Caverns, or overhead environments such as an overhang jutting out of a sea wall, a volcanic lava tunnel in the ocean or a limestone cavern or sinkhole in a spring fed lake often house interesting marine-life or rock formations showing-off natures beauty.

The famous Cenotes and cavern diving of the Riviera Maya , Mexico are perhaps one of the most beautiful dive sites in the world. Florida is famous for its scuba diving limestone sinkholes and caverns which only experienced cavern divers can witness. A Cavern diving specialty course acts as a stepping stone introducing the diver to full cave diving by building up the confidence and skills of the diver and increasing his/her awareness and proficiency, which can be done in back mounted cylinders or Sidemount cylinders.


What is a Cavern zone?

_DSC2506When diving within the light zone of a cave…the area near the cave entrance where natural light is always visible… or atmospheric surface air is always possible to breathe… you’re in the cavern zone.

As with wreck diving, this is also overhead environment diving, without direct vertical access to the surface for air.

Gas management, ie ‘Rule of thirds’ of your air supply, still applies here in cavern diving, whether you’re backmount or Sidemount.



Whats involved?

The purpose of the Cavern Diver course is to familiarize divers with the skills, knowledge, planning, organization, procedur_DSC2346es and techniques, problems and hazards of cavern diving.

The Cavern Diver course is intended to provide a safe, supervised introduction to diving in natural overhead environments.

You’ll learn Cavern navigation and line protocols, team awareness and communication, cave diving etiquette and respect for the environment, planning, organization, techniques, problems and hazards of cavern diving, special equipment use, such as lights, guidelines, reels and redundant breathing systems, air sharing, disorientation, line problems and other emergency procedures specific to cavern diving, silt prevention, problem solving, buoyancy control, air management and emergency procedures, depth and distance limits for cavern diving



Course duration

This is a challenging and very exciting _DSC2295

3day course that includes a day of theory, equipment configuration, dry land skills and four training dives over a minimum of two days.

During your first two open water dives you’ll practice various techniques in anti-silting techniques, line handling, reel use, positional and line awareness, blacked out mask and emergency procedures, gas planning in a non overhead enviroment. But, for your next two dives, you’re headed into the cavern, staying within the light zone and 60 metres/180 feet total distance from the surface.

Remember…there’s no substitute for proper training for diving in any overhead environment and these beautiful realms should be treated with the utmost respect.
