About: A form of underwater diving with breathing equipment. Stands for Self-Contained Underwater Breathing Apparatus. Swimming on or through a body of water with a snorkeling mask.
Recreational or professional. Specific recreational interests include cave diving, wreck diving and ice diving. Professional purposes include for civil engineering, underwater welding,offshore construction or for military purposes. Recreational purposes include observing fish and algae and coral reefs especially in water bodies with minimal waves and warm waters; also interesting things to see near the water surface.
Requires training in how to use the breathing equipment, safety procedures and troubleshooting. Although no centralized certifying or regulatory agency many dive rental and sale shops require proof of diver certification. Requires no training. Snorkelers favor shallow reefs ranging from sea level to 3-12 feet. Deeper reefs are also good, but repeated breath holding to dive to those depths limit the number of practitioners and raises the bar on fitness and skill level.
Effect on Health:
Effects of breathing compressed air such as decompression sickness, nitrogen narcosis, oxygen toxicity, refraction and underwater vision. Greatest danger is not being spotted by jet skis & crafts, as a diver is often submerged under water with only a tube sticking out of the water. Contact with poisonous coral, dehydration and hyperventilation. Sun burn is also common with long hour
