Diving – essentials

So, after weighing all the pros and cons, it was made a clear decision to go diving. But, besides the fact that it is healthy and brings a lot of new impressions and in addition helps to burn extra calories, you probably do not know anything. The sea is not for you inflatable pools, here it is necessary to approach with extreme caution and knowledge of the matter.
Before you start training (and without them, no one will give you swim in the open sea), you need to purchase the necessary equipment:
Wetsuit. Its purpose is to reduce the level of water exposure on the body immersed. It also provides thermal insulation and to a lesser extent protects against possible damage. For a novice scuba diver best fit suits medium thickness with a pad of plush or nylon. The color of the wetsuit depends entirely on the tastes of its future owner. Due to the fact that diving is becoming increasingly popular among women, wetsuit manufacturers have begun to produce products with fashionable colors and patterns.

Scuba diving for breathing. The word itself comes from the connection of the lat. words aqua (water) and eng. the words lung (lungs). This item is a cylinder of compressed air and a tube for breathing diverted from it. The most common are scuba tanks with a volume of 12-15 liters with a pressure of 200 atmospheres. Currently, scientists are developing so-called artificial gills that allow you to extract air directly from the water space.

Flippers. This item is your personal underwater engine. Without it, moving at depth is almost impossible. Visually, flippers are two trapeziums, most often made of plastic, which are intended for use on the legs. They distinguish both ordinary flippers, which are worn separately for each leg, and monofinishes – two ordinary ones, glued into one. Monofinas have a large area and give the diver a kind of “mermaid”.

Mask. We can say that this object serves as a window into the underwater world, because it is thanks to the mask that you can keep your eyes under water open. Usually it consists of a special thick glass, an elastic frame, which should fit close to the face to ensure complete sealing, a special strap. It is desirable that the mask had a slider or a special buckle, which will allow you to adjust the size of the strap.
If earlier for a comfortable beach holiday you needed items such as fashionable swimsuits, inflatable mattresses, large towels and fashionable hats, now in the first place you will have huge air tanks, masks of various colors and space-saving flippers.
