A scuba diving course is required if you want to become a cavern diver. The course includes four dives. The first is an outdoor practice, in which you will learn how to handle line and reel, avoid silt-outs and manage air. 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
Cave diving safety protocols should follow the Rule of Threes. A cave diver must have three sources of light and at least two tanks, one of which should be independent or multi-mounted. The gas should be divided into three different sections so that they can survive the dive. If the dive team has previous experience with cave diving, a more conservative approach to gas management is recommended. Cave divers need to be aware of cave hazards and practice safe diving techniques.
Equipment
Cave diving is a sport that requires specific equipment. It is important to carry two types of safety reels. One safety reel should be used to run the guideline while the other should maintain the line tension in the cave. Before you go cavern diving, ensure that every diver has a safety rope with enough line to reach cave's entrance. 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 prevent a jam, trim approximately 10 meters (30 ft.) of line before you use the reel. This will reduce the risk for entanglement.
Maximum penetration
TDI offers a cavern diving course for scuba divers who want to dive in areas that do not allow 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. In this course, you will learn how to safely navigate the confined spaces that are often hidden from view.
Maximum depth
Cavern diving is subject to certain restrictions. 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. Cavern diving is a great option for those who are curious. You should be familiar with basic cave safety procedures, and you need to know your limits. Before diving in caverns, you will need to have had some experience. You can then embark on a journey into cavern diving.
