Safety
Cave diving safety protocols follow the Rule of Threes. The Cave Diver should have three sources for light and at minimum two tanks. 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 should be careful when diving in caves.
Equipment
Cave diving requires the use of specific equipment. Two safety reels should be carried. One should be used as a guideline reel, and the other should be used during the dive. 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. You should trim about 10 meters (30 feet) of your line before you use it to avoid jamming.
