Scuba diving is a recreational activity that involves going underwater and breathing from a tank. There are several types of diving, including open circuit scuba, closed circuit rebreather, and surface supplied diving. Open circuit scuba uses compressed air tanks for breathing, while closed circuit rebreathers use a mixture of oxygen and recycled exhaled gases. Surface-supplied diving uses a hose connected to an external source of gas such as a compressor or tank on the boat. Each type of diving has its own set of safety precautions and requirements. It's important to research each one before deciding which type of diving is right for you.
