People who do not know what a dive, is often confused with his diving business. But it belongs to the professional activity. Diver undergoes special training to be authorized to perform certain underwater operations. A diver - this is an ordinary amateur diver, dive for pleasure. It floats just to relax and enjoy the underwater beauty. Well, we present below the actual description of diving. Let's get started.

First Diving

Man since ancient times tried to conquer the depths of the sea. But at the dawn of civilization, he has a one problem - the lack of oxygen. To solve it, the primitive divers began to train breathing to increase lung capacity. But the body has its limits, and the five minutes was not enough. And there were bags of air, which sewed the skins of animals. But they did not differ convenience, because it sought to emerge, thereby pulling the diver to the surface. And the hole in the bag helped leak the precious oxygen.

The air dome

For many centuries the problem was insoluble. It took several periods before the descendants of primitive divers were able to find a solution. Only in the XVI century there was a tool that gave hope that divers finally conquer the seabed. They became two-meter air dome in the shape of a bell. Inside it sat on the bench diver and maneuvered in the water column. On top of the dome was connected hose, and the air is pumped through a pump placed in the boat. Though in this invention, and it was a lot of advantages, they all overlap instability of the structure. Dome constantly strove to overturn. With this issue tried to fight with the help of anchors, but the game were not worth the candle - the divers did not want to use it, and the manufacturing process is very expensive.

Diving Suit

The breakthrough, which allowed people to see hidden by the underwater world, occurred only in the XIX century. In 1837, Englishman Augustus Siebe invented a diving suit. It is used in our days without any major changes. Actually the costume consisted of a steel helmet with portholes, air hose and rubber suit. On the shoulders of the diver wore a special shirt front on which steel bolts fastened helmet, and on foot - lead shoes. The design came out very successful, but there was a problem - the diver was chained to the ship. And people want freedom of navigation.

The invention Cousteau

And they got it in 1945. The legendary French diver Jacques Cousteau invented the bottle for diving with compressed air inside. He was attached to the back of the diver and had a breathing hose with a special valve. The hose was device diverting the water column in the exhaled air. It also aligns the pressure of compressed oxygen to the environmental indicators. Finally, people were able to move freely underwater.

What is diving?

We can say, this activity opens diver new beautiful world. He was thousands of years with people and waited until it opened. However, even in the current development of technology, we are very few know about him. Diver opened only a few of its secrets. And others still enticing, motivating thousands of divers to the study of the ocean depths. Diving - this thrilling experience in traveling and getting to know like-minded people, and the thrill when submerged, and recreation. Perhaps the most striking feature that it provides the diver - this feeling of almost complete weightlessness and absolute freedom of movement. On land we can move backward, forward, left and right, and when diving is still added up and down. Such can only be experienced in space, where gravity does not have authority over a man.

This type of holiday is developing very actively. Created a variety of courses, where you can go diving training. There's talk about all the strict rules and requirements to ensure the safety of the diver. And they can not be ignored! Some people think that doing diving without any training, but this is an illusion. Naturally, it is possible to dive on their own without going through special training. But in this case, the behavior at depth and further process of ascent could end in tragedy. It's like a car - no one sits immediately behind the wheel after purchasing it. First, training in a driving school, and only after the conquest of motorways. But do not worry about the wasted time and effort. They will be repaid a hundredfold.

Variations

This kind of diving is used to this day not only as a pleasant pastime, but also for the production of nautical gifts. For example, Korean and Japanese divers are still searching for pearls in this way. They hold the water from one to five minutes.
• Diving chamber filled with oxygen. This submersible available air cleaning and delivery system, and support optimal atmospheric pressure. Most often, such a device is not used for recreation, and for research purposes.
• Diving with decompression system. The scuba diver through a hose supplied with compressed air. A special device regulates the pressure, which is on the surface.
• Scuba Diving. This is the last kind of diving. In her on the back of the diver in scuba diving tank is attached to the oxygen. There are two types of scuba systems - with a closed and open loop. In the first case spetssistema regenerating air and re-diver inhales it. In the second of exhalation after it is output in the water column.

Finally,

Now that you know what the diving and what to expect for those who dare to rest this way. We'll have to work hard in training. Well, I spend a lot of money on training and diving equipment. But it's worth it! Pay handsomely for your efforts will be stunning views of the underwater kingdom, which will open eyes diver.
