A diving center is a facility that offers commercial support, equipment and courses for learning and performing dives. Many centers operate according to the guidelines of the Standard ISO 24803. They standardize the requirements for recreational diving service providers. Dive shop Atlanta offers logistical support in all activities related to recreational diving. This includes renting, maintenance and repairing of diving equipment as well as filling the compressed air bottles.
Most centers have a diving school with a separate meeting room for teaching diving theory lessons. Guided trips are also organized and carried out. Many facilities have showers and offer the possibility to change clothes and place to exchange experiences. Some have an affiliated business for the sale of diving equipment. While others are located in diving areas and maintain boats and rafts.
History of diving equipment dates back to the Middle Ages, when the researchers used a technical device called the diving bell. Its essence is that when immersed, air remains inside the bell, which is enough for man to work underwater for some time. In 1689, Denis Papin proposed to add a powerful piston pump to the diving bell, which would replenish air used.
Necessarily, when the cylinder is filled with another kind of gas mixture other than compressed air visual identification alerting the diver of its contents must be shown. The cylinder is typically constructed from steel, but there are some made of aluminum to keep the weight light.
The wetsuits prevent loss of body heat and protect the skin from burns, poisonous animals or cuts. In many cases, they are made of neoprene, a type of rubber that contains thousands of tiny bubbles inside. There are three types of wetsuits: wet, dry and semi-dry. A wetsuit lets in water, which upon contact with the skin creates an insulating layer that protects the diver from heat loss to the environment. These are usually made of neoprene and range from 2.5 mm to 7 mm thick.
Dry clothing does not allow any water, keeping divers completely dry. They are usually made in a nylon mesh of high density. A characteristic that allows a valve to inflate or deflate clothing requires technical training. The semi-dry suit allows the entry of some water that remains throughout the dive. These versions are typically made of neoprene with a thickness of 5mm to 7mm.
Some equipment is used to offset the buoyancy caused mainly by insulating clothing. The amount of ballast varies from diver to diver, so depending on your natural buoyancy, this quantity is theoretically 1 kg per body mass. The exact way to calculate the optimal ballast of each diver is to keep adding lead until half immersed.
The ballast has generally been in the form of lead due to its density, both coated and uncoated blocks and bags. The BCD vest (buoyancy compensator device) is required to maintain perfect buoyancy. The BCD vest consists of vest pockets that allow air to pass. The diver himself operates a button (button insulator) connected to a low pressure hose on the drum. Inflating the vest controls buoyancy, it is neutral or positive . Deflating changes buoyancy path to neutral or negative. The vest still has 4 valves with which it draws air, it is placed in strategic place so that you can always get air regardless of the position.
