Scuba diving is a type of underwater diving in which divers employ breathing apparatuses with varying but limited endurance since they are totally independent of a surface breathing gas supply. Self-contained underwater Breathing Apparatus is what the term scuba stands for, and it was created by Christian J. Lambertsen in a 1952 patent application. Scuba divers have more freedom and mobility than surface-supplied divers and can stay below for longer than free divers since they carry their supply of breathing gas, which is often compressed air. While compressed air is still often used, enhanced air, or nitrox, is a gas blend with a greater oxygen content that has gained popularity since it requires less nitrogen to be inhaled during prolonged or repetitive dives.
Open-circuit scuba systems, which consist of one or more diving cylinders storing breathing gas at high pressure and delivered to the diver at ambient pressure via a diving regulator, release the breathing gas into the environment when it is exhaled. Extra cylinders for range extension, decompression gas, or emergency breathing gas can be among them.
Exhaled gases can be recycled with closed- or semi-closed-circuit rebreather diving systems. Since less gas is consumed than in an open-circuit dive, a smaller cylinder or cylinders can be utilised for the same amount of dive time. Rebreathers are more time-efficient underwater than open-circuit diving for the same metabolic gas consumption; also, they create less noise and fewer bubbles than open-circuit diving, which appeals to convert military personnel.
Scuba diving can be done for fun or for a living in a variety of contexts, such as science, the military, or public safety. However, when it comes to commercial diving, most operators employ equipment that is provided by the surface. Frogmen, battle divers, assault swimmers, and other terms are used to describe scuba divers who participate in clandestine military operations.
Scuba divers use fins attached to their feet to propel themselves below, but they can also use a diver propulsion device or a sledge pulled from the surface for external propulsion. More gear required for scuba diving includes a mask to enhance vision underwater, a diving suit for exposure protection, ballast weights to counteract excess buoyancy, buoyancy control equipment, and gear specific to the particular conditions and goal of the dive, such as a snorkel for surface swimming, a cutting tool for entanglement management, lights, a dive computer to track decompression status, and signalling devices. Diving instructors connected to the diver certification organisations educate scuba divers in the techniques and methods suitable for their certification level.
History of scuba diving
The history of scuba diving gear and diving itself are intertwined. Two fundamental designs for underwater breathing apparatus had been developed by the turn of the 20th century: closed-circuit breathing apparatus, which filters the diver's carbon dioxide from exhaled unused oxygen and recirculates it, and open-circuit surface-supplied equipment, which vents the diver's exhaled gas directly into the water. When necessary, additional oxygen is added to the closed-circuit breathing apparatus. In the lack of dependable, affordable, and transportable high-pressure gas storage tanks, closed-circuit equipment was easier to modify for scuba diving.
By the middle of the 20th century, high-pressure gas cylinders were readily available, and two scuba diving systems had developed: open-circuit scuba, in which the diver's exhaled breath is vented straight into the water, and closed-circuit scuba, in which the diver's exhaled breath is cleaned of carbon dioxide and then circulated with oxygen added. Because the risk of oxygen poisoning grows with depth, oxygen rebreathers can only be used to a very limited depth. Additionally, the systems for mixed gas rebreathers that were previously available were rather large and made to fit inside diving helmets.
Working for Siebe Gorman in London in 1878, diving engineer Henry Fleuss devised and manufactured the first commercially viable scuba rebreather.
scuba Diving equipment
Scuba diving equipment, also known as scuba gear, is essential for divers to explore underwater environments safely and efficiently. This gear includes a breathing apparatus, diving suit, buoyancy control and weighting systems, fins for mobility, and a mask to enhance underwater vision. Additionally, divers use various safety equipment and accessories to ensure a secure and enjoyable diving experience. From the basics like tanks and regulators to advanced gadgets, each piece of equipment plays a crucial role in making scuba diving both possible and pleasurable. Whether you're a beginner or an experienced diver, having the right gear is key to a successful dive.
Breathing apparatus
The defining equipment used by a scuba diver is the eponymous scuba, the self-contained underwater breathing apparatus that allows the diver to breathe while diving and is transported by the diver. It is also commonly referred to as the scuba set.
When one descends, the water imposes rising hydrostatic pressure of around 1 bar (14.7 pounds per square inch) for every 10 m (33 ft) of depth, on top of the regular air pressure at the surface. For regulated lung inflation, the pressure of the breathed breath must equal the ambient or surrounding pressure. Under 3 feet (0.9 meters) of water, it becomes nearly difficult to breathe air through a tube at standard atmospheric pressure.
The majority of recreational scuba divers use a mouthpiece to get breathing gas from a demand valve or rebreather and a half mask to protect their eyes and nose. It doesn't take long for mouthpiece breathing to become second nature. A full-face mask, which covers the mouth, nose, and eyes while frequently allowing the diver to breathe via their nose, is the other typical configuration. Full-face masks are more frequently worn by experienced scuba divers, as they safeguard the diver's airway in the event of unconsciousness.
