To become a cavern dive instructor, you must complete a scuba diver course. This course includes four scuba dives: the first is an outdoor practice dive, where you will learn the basic techniques of handling line and reel, avoiding silt-outs, and air management. Your instructor will show you how plan your dive, and keep your air and orientation under control. After the course you will be certified to dive in caves and other caves following safety rules.
Safety rules
Cave diving safety protocols 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 previous experience with cave diving, a more conservative approach to gas management is recommended. Cave divers should not only avoid cave hazards but also practice safe diving practices.
Equipment
Cave diving requires specialized equipment. It is essential to have two types of safety gear. One should be used for guideline running, while the other should keep the line tension high while the diver is in a cave. Before you go cavern diving, ensure that every diver has a safety rope with enough line to reach cave's entrance. The majority of manufacturers will fill the reels with guideline. This increases the likelihood of them jamming. 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 into caverns and overhangs. This course is not required to be able to dive in caverns, but it will teach you the skills necessary to make the most out of these environments. In this course, you will learn how to safely navigate the confined spaces that are often hidden from view.
Maximum depth
Cavern diving has its limitations. Cavern diving should not be done at night. Cavern diving requires advanced training, which is not the case for other types. If you're curious about diving in caverns, you'll need to learn the basic cave safety procedures and know your limits. It is a good idea to have some experience in cave diving before you attempt it. Then, you can begin a journey into the world of cavern diving!
