To become a cavern dive instructor, you must complete a scuba diver course. The course includes four scuba divers. The first is an outdoors practice dive. Here you will learn the basics of handling line, reel, avoiding silt, and managing air. Your instructor will show you how plan your dive, and keep your air and orientation under control. You will be able, upon completion, to dive in caves or other caves that follow safety rules.
Safety rules
Safety protocols for cave diving follow the Rule of Threes. The Cave Diver should have three sources for light and at minimum two tanks. To ensure they are able to survive the dive, they should separate their gas into three sections. If the dive team has experience in diving in caves, a more conservative gas management plan will be preferred. Cave divers must practice safe diving practices in order to avoid hazards from caves.
Equipment
Cave diving requires the use of specific equipment. Two safety reels should be carried. 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. The majority of manufacturers will fill the reels with guideline. This increases the likelihood of them jamming. To avoid a jam, you should cut off about 10 meters (30 ft) of line before use to reduce the risk of entanglement.
Maximum penetration
TDI offers a cavern course to scuba divers looking to dive in areas where it is not possible to reach the vertical. This includes overhangs and cavern diving. 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 help you navigate dangerously through the small spaces that are sometimes hidden from your eyes.
Maximum depth
Cavern diving has some limitations. Cavern diving must be avoided at night. Cavern diving requires more training than other types. Cavern diving requires that you know your limits and learn basic cave safety procedures. Before diving in caverns, you will need to have had some experience. After that, you are ready to embark on your journey into the cavern diving world!
