Diver's equipment includes SCUBA, which stands for Self-Contained Underwater Breathing Apparatus. SCUBA is a type of breathing apparatus that allows divers to stay underwater for extended periods of time. It consists of a tank of compressed air, a regulator, and a face mask. The air tank is worn on the back and the regulator is connected to the tank, allowing the diver to breathe underwater. The face mask provides the diver with a clear view of their surroundings. SCUBA is essential for deep sea diving and is used by recreational and professional divers alike.
