SCUBA (Self Contained Underwater Breathing Apparatus) Diving is a popular recreational, underwater activity made possible by providing breathing gas, usually air. The equipment used is either an ‘open circuit’ Aqualung or a ‘closed circuit’  Re-breather in which exhaled gas is recycled. Although there are obvious commercial applications in Scuba Diving, the numerous recreational activities (cave diving, wreck diving, marine surveys, underwater photography, nautical archaeology etc) dominate the internet and there are many centres providing such opportunities all round the world. Safety is clearly a key factor, with courses also available all round the world to controlled standards.

Our senses work differently. We see differently because of the optics of water. We hear differently because sound travels much faster. There is the drag of water and the fact that the laws of gravity no longer seem to apply the way we instinctively know them on dry land. Colors are different because some of them are absorbed by water very differently than by air. Water is a much better conductor of heat than air is. As a result, we lose heat much more quickly in cold water. Most importantly, though, water is much, much denser than air. At sea level, water weighs about 800 times more than air. Which means that as you dive, you are quickly subjected to very substantial pressure. Since the human body consists mostly of water, you're in no danger of being crushed. However the gasses inside the human body are greatly affected. They get compressed a great deal the deeper you dive, and the impact of that is the most important reason why any diver must be aware of the physics of being underwater.  From Scuba Diving Info.  Read on ....         The principles from Wikipedia Diving Physics from Scuba Diving Info; what you need to understand about Buoyancy, the Gasses and the laws covering them, sound, light and heat loss.

History of Scuba	know the background    Rebreather  History	top
SCUBA diving has mushroomed into a multi billion dollar business with thousands of dive shops, instructors and exotic destinations all over the world. Following this, there is a new group of divers, who seek out their history and endeavor to understand their origins. Investigating this history has resulted in greater recognition of those who made that history. More and more vintage diving gear appears on internet auctions and the price rises are a practical measure of that increased historical interest.
