No diving enthusiast can do without high-quality and, most importantly, reliable scuba gear. Modern devices are open-loop units in which inhalation is carried out by scuba gear, and the oxygen used is released into the water. We owe the creation of such unique devices to French inventors.

Oddly enough, but we owe the invention to 2 French, who were the discoverers of this object. We are talking about Augusto Deneiruz, who was a lieutenant in the army and his friend Benoit Rouqueirole, an engineer. Their acquaintance was accidental, but without a doubt, fateful. They were responsible for developing the first prototype of the device, which was soon destined to be born. We are talking about scuba gear, which is based on the use of a membrane mechanism. It is able to influence the pressure indicator depending on the depth at which it is located.
Initially it was used for various rescue operations in mines. Auguste, having learned about the innovation, suggested using a structure for lowering people under water. This is how the prototype of modern scuba gear appeared.
The first prototype was not devoid of drawbacks: it could withstand a slight pressure, so the scuba diver could not reach significant depth or stay under water as long as required. Over the years, the apparatus has undergone significant changes. This happened largely thanks to Jacques Yves Cousteau, once a young French officer. It was this man who developed the automatic respiratory system, thanks to which oxygen is supplied. The process is similar to breathing, when a person consumes air masses from the environment. This made being underwater more comfortable and swimming longer.
The name "Scuba" comes from 2 words: "aqua", which is translated from Latin as "water", and "lung", translated from English as "light". The word "scuba" is patented by Air Liquid.
During the Second World War, the device was widely used by the military as a special device that allows you to swim underwater. In peacetime, this device is an integral part of equipment for those who like diving to a significant depth.
Popular scuba diving models differ in breathing patterns, and therefore they are divided into the following types:
The best manufacturers produce units that differ in the device, and therefore they are divided into the following types:
Based on the number of cylinders, there are 3, 2 and 1-cylinder models. Differences are also in the breathing machine, therefore, devices are divided into the following types:
The main components of scuba gear are:
The elements | Description |
---|---|
Balloon | Special containers with compressed air inside. In most cases, they have a volume of 5 or 7 liters, but there are new items for 10 and 14 liters. In shape, they resemble a cylinder with an elongated neck, to which a tube or pipe is attached. Manufacturing material - carbon fiber, steel, aluminum alloys, titanium, etc. Materials differ in cost, wear resistance and weight, but they meet the main requirement - they can withstand significant compression (up to 300 atm.). As for steel structures, in order to avoid the appearance of corrosion, they are treated with a special anti-corrosion compound. |
Regulator | Consists of a reducer and a lung demand valve. The reducer is designed to reduce the pressure of the compressed air coming from the cylinder to an average level. After that, the air with a medium compression level enters the hose, and then into the lung governed demand valve, where it gets the optimal value. The scuba diver uses it to breathe through the mouthpiece. The scuba tanks are equipped with main and reserve regulators. Their number varies depending on the model and manufacturer. |
Buoyancy compensator | A device, the main task of which is to compensate for the variable buoyancy of a person during a dive and while on the surface. |
Each person determines the selection criteria for himself independently, however, the recommendations of experts boil down to the following: it is worth paying special attention to the cylinders. Which one is better to buy depends on many factors, but above all on the quality of the material of manufacture.
The most common are aluminum and steel: aluminum is not afraid of corrosion, and steel has strength. The best option for professional divers is steel cylinders, which, when used and cared for correctly, have a long service life. But it is worth checking the presence of a special anti-corrosion coating.
According to scuba divers, the choice of the volume and number of cylinders must be carefully. It all depends on the depth and duration of the dive. The longer the voyage, the more air will be required.
Often, professional divers do not take cameras with them, but a compressor. It helps you to reload the cameras yourself. The average price of such a device is significant, so you can purchase a second-hand model. However, if finances permit, it is better to opt for a new compressor in which you will be completely confident. For novice divers, such equipment is optional and you can save on it.
Which company is better to buy, each is determined independently, based on personal preferences and money. The good ones are expensive, the budget options are more suitable for beginners. In order not to be mistaken when choosing, you need to familiarize yourself with the functionality, study ratings and analyze customer reviews.
It is best to visit specialized markets, get advice from a sales manager, choose the model you like by color and design. The kit can be ordered online from the online store. For the price it will come out cheaper, but there is no guarantee that it will not be possible to purchase a low-quality fake.
There is another option - do it yourself scuba diving. There are even step-by-step instructions on the Internet on how to make a device at home. Craftsmen use gas cylinders and gas masks for these purposes. The result is inexpensive products, but how reliable and durable are they? According to buyers, it is not worth saving on your own health and risking your life.

For those who prefer to explore the underwater worlds and admire their inhabitants, scuba gear is an indispensable component in general equipment. It is he who allows you to breathe under water, stay at a depth for a long time and swim close to the inhabitants of the underwater world, without fear of frightening them off.
The variety of scuba gear is impressive. They are mini and with significant volume, additional functions and without them, made of various materials. But their main structural element, on which the safety and duration of the dive depends, is the cylinder.
Regulators are fragile and complex. In order for these elements to serve faithfully for a long time, they need proper care. After each use, they must be rinsed out of salt. When drying the rubber components of the machine, you need to make sure that they are not exposed to direct sunlight, otherwise they may dry out and become unusable.
