There are different types of jackets used in diving: the vest type jacket, semi-wing and wing. These are sold at dive shop Atlanta. Regulator and Octopus are the main tools that allows divers to breathe underwater. They have the primary function of reducing cylinder pressure to an intermediate pressure in the first stage and then to a breathable pressure in the second stage. It consists of a membrane, it allows the passage of air through the whiskers. Air pressure hovers at of 1 bar on the surface. As the diver descends, it will compensate by increasing air pressure.
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.
As the name implies, it is the same air breathed on the surface (21% O2, 79% N2), which is filtered to remove moisture before compression in the cylinder. For some types of diving, cylinders can be filled with other types of gas mixture (e. G. Nitrox, trimix, etc.), specific technical diving knowledge is required.
A snorkel works with or without valves. The tube with self - draining valve is not very advisable for spearfishing, since the noise that it causes is enough to scare the fish away. The diving mask gives a clear view of the seabed to the diver because light rays can not be focused without the presence of a layer of air before the eyes.
Another curious effect of sight in the sea entails the apparent alignment of objects by about 25% and even higher proportion. Thus, if a diver sees a fish that is one meter away, he must understand that the actual distance will be something around 75 centimeters. This effect is known as refraction.
Since no arms are used in underwater swimming leg movement is responsible for the displacement of water. Made of rubber or silicone, the fins may be of two designs: open heel, which almost always requires the use of a boot inside the fin and a closed heel. They vary in size according to use, as a rule there is the large (jumbo) for snorkeling, since higher speed is required for the diver to reach the desired depth. And there is no air supply beyond the limits of lungs.
The dive knife is considered a safety tool. If a diver gets tangled up in the background on some string or fishing line, the knife will be essential to free him from trouble. The diving knife can also be used as a hammer, screwdriver, saw and even yardstick. Its use is especially autonomous, and should not affect marine life. However, in practice hunting, the knife is useful for cutting and removing fish caught.
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.
