Scuba is an underwater swimming activity that allows you to explore oceans, lakes and rivers. It involves wearing equipment such as a tank, regulator, wetsuit and mask that houses a separate air supply from that found above water. It requires training and practice to master but once mastered it is one of the most rewarding activities in water.

The equipment used for scuba diving consists of a metal tank that holds compressed air and a regulator with a mouthpiece attached to a thin hose that transports the air from the tank to the diver’s mouth at a lower pressure than is found under water. This is done to reduce the risk of nitrogen narcosis.

When you are scuba diving it is important to follow the rules of the dive site and your buddy. It is also a good idea to stay hydrated before diving as dehydration can be dangerous. It is also important to pause during the dive and test your equipment to ensure it is working properly.

Scuba is a great way to see a wide variety of marine life in an amazing setting. From shipwrecks and artificial reefs to underwater caverns, walls and drop offs the deep sea has a plethora of marine wonders for you to discover. It is also a good place to see other people enjoying scuba as there are many events like expos for scuba divers where they can learn about innovations in the sport and buy gear.
