You will need to take a scuba dive course if you plan on becoming a cavern divers. This course includes four scuba diver dives. Your instructor will teach you how to plan your dive as well as how to keep your orientation and control your air. Upon completion of the course, you will be able to dive in caves or other caves with safety rules.
Safety rules
Safety protocols for cave diving follow the Rule of Threes. The cave diver should have three types of light sources and at least two tanks. They should also separate their gas into three distinct sections in order to have enough to last the dive. If the dive team has experience in diving in caves, a more conservative gas management plan will be preferred. In addition to avoiding cave hazards, cave divers should practice safe diving practices.
Equipment
Cave diving requires specific equipment. You should have two safety reels. One safety reel should be used to run the guideline while the other should maintain the line tension in the cave. Each diver should have a safety reel that has enough line to reach the cave's entry and the longest permanent line. Many manufacturers will bundle the spools with guideline at the edge when you purchase a new reel. This makes them more likely to jam. To avoid jamming, remove approximately 10 meters (30ft), of line prior to use.
Maximum penetration
TDI offers a cavern divers course. This course is for scuba divers who desire to dive in areas without direct vertical access. This includes diving in caverns and underhangs. It is not mandatory to sign up for a cavern dive course. However, the course will provide the necessary skills to make the most of the environment. This course will teach you how to navigate the narrow spaces often hidden from your view.
Maximum depth
Cavern diving comes with its own limitations. Cavern diving requires that you never dive at night and that you are aware of your limits. Cavern diving is more difficult than other types of diving. You will need to be familiar with cave safety procedures and your limits if you are interested in diving in caverns. It is a good idea to have some experience in cave diving before you attempt it. After that, you are ready to embark on your journey into the cavern diving world!
