Cavern and Cave Diving courses

Cavern and Cave Diving courses

Cavern and Cave diving courses give you the opportunity to explore an underwater world that very few people ever get to see.  These courses train you to navigate overhead environments with limited visibility. At DJL when we teach cavern and cave diving courses we offer ANDI certification with training by Bruce Konefe.

Diving in overhead environments requires extensive, specialized training due to the unique set of risks and skills of this environment. Your entry to this area of diving is the cavern zone. The cavern zone is the area of cave still reached by natural daylight and limited to a total linear distance of 40m from the surface.

At DJL we offer the Cavern Diver specialty, a solid introduction to the world of diving in overhead environments.
In this course you will learn the foundation skills to conduct the dives safely, including line laying, marker use, and emergency procedures for exiting overhead environments in zero visibility conditions.

This level of training is far beyond the experience of the typical open water instructor, so we recommend you conduct this course, only with experienced technical diving instructors. At DJL Tech we have some of the most experienced tech divers in the country and a reputation as one of the original tech diving schools on Koh Tao.

We recommend you combine your cavern course with a redundant air supply course such as Sidemount, or Tec basics, or go the whole way with one of our “FULL Techie” packages, that include options such as Tec Deep (Decompresion diving) Gas Blender, Equipment Specialist, self-reliant, Advanced wreck and more.

Level 2 Cavern Diver course.

The Cavern Diver course usually lasts 3-4 days. While you do penetrate the cavern you will remain in the daylight zone. There is no decompression during this course. You will only need to carry one tank and RBS. The skills that divers require to complete this course revolve around safety and include line laying and out of air drills.

Level 3 Cave Diver course.

Once students reach the standard to dive a cavern the next step is full penetration of a cave. The level of skills required to successfully complete the Cave Diver course increases significantly from the safety based skills of the Cavern Diver course. You will learn the procedures for locating your buddy if they get lost, getting out of an entanglement situation, and what to do if you lose the main line. You will be decompression diving on double tanks as you venture further into the cave system.

Level 4 Full Cave course.

The Full Cave course will train you up to the highest standard. You will be using full technical equipment and will learn how to do jumps and gaps and also how to contend with smaller restrictions. Part of the Full Cave course focuses on teaching students how to stage tanks which enables additional penetration.Your instructor will bring this into practice on 2 of the dives where 1 tank will be staged and 2 further dives where 2 tanks are staged.

Level 5 Cave Exploration course.

The Cave Exploration course teaches students how to dive deep caves. Narcosis is an issue to avoid in an overhead environment. Therefore students need to be using optimum oxygen and helium mixes. During this course we teach students how to stage multiple tanks, setting up a habitat and breathing o2 whilst they are in a habitat.
