There are several things relating to scuba diving Atlanta residents will need to know if they intend to take part in this sport. In scuba diving, the diver has to take their source of air with them as they enter the deep waters. In other types of diving, an external source from the surface of the sea is used or the diver simply decides to hold their breath.
The word SCUBA is historically an acronym, self- contained underwater breathing apparatus. The equipment was originally used by soldiers for underwater warfare. Military frogmen apply this technique in following up enemy lines, directly confronting their enemies or setting up bombs. The police department also uses this method in crime investigations involving water and in performing a search.
The field of professional diving is one that has continued to generate great interest from many different areas. Persons that want to be professional divers are among those that need to have highly specialised scuba diving equipment. This is because of the dangers that are posed by the deep waters. Professional divers offer training to other people who have an interest in this sport. Apart from this, they also play an important role in field such as marine biology, underwater archaeology, geology, oceanography and photography.
The main challenge that a deep sea diver is faced with is increasing pressures that are exerted by the large volume of water above them. This pressure increases as they go deeper into the ocean. Excess pressure makes breathing very difficult. Fortunately, scuba diving equipment is usually fitted special valves that are used to regulate the amount of pressures that the diver is exposed to. As a result, they can breathe comfortably regardless of the depth of sea.
The most frequently used set is the open circuit regulator connected to high pressure gas cylinder. It is a double stage device in which the first stage is connected to the cylinder valve while the second is linked to the mouthpiece. The initial stage regulator serves to reduce pressure in the cylinder from about 300 bars to 10 bars above the surrounding pressure. The second stage delivers the air whose pressure has now been adjusted to the mouth. Exhaled air is passed out into the surrounding water as waste.
The other type of equipment found in the markets is what is known as the rebreather. This is less commonly used. Two types of rebreathers exist. These are the closed circuit, CCR and the semi-closed (SCR). The main difference that exists between rebreathers and open circuits is that in the former exhaled air is not released as waste into the environment. Rather, it is processed to recover some oxygen. They main downside is that they have a higher failure rate.
There are many other pieces of equipment that have to be used alongside the apparatus. These include, among others, suits, buoyancy compensators and weighing systems. This equipment allows the user to keep the speed of descent and ascent constant. The advantage of this is that it reduces the effort needed for swimming and also the consumption of oxygen.
There are a number of hazards relating to scuba diving Atlanta residents may want to know. The most frequently encountered include oxygen toxicity, barotrauma, hypothermia, nitrogen narcosis and incompetence. Dry suits are greatly helpful in helping avoid hypothermia. The suits also help prevent damage to the skin by underwater organisms. It is important to ensure that all the safety precautions are taken to avoid accidents.
