Scuba Diving Weight Belts
The heavy scuba diving weight belts means the body that serve to ballast / load an item (boat, blimp, etc. ) in order to move the center of gravity and increase the mass (inertia or weight) of an object. On large ships, the ballast provides stability and / or the depression needed to obtain a sufficient immersion of the propeller and better quality water. Formerly, the tall ships were ballasted with sand. Ships today are with sea water injected into the building known as ballast water sea scuba diving, spearfishing and diving, divers are often forced to weigh down in order to immerse themselves properly. The natural buoyancy of the human body associated with the neoprene wetsuit tend to maintain the individual at the surface. The ballast, usually consisting of weights, a scuba diving weight belts belt or a harness lead, should be enough for the diver to dive without difficulty or take a decompression stop at 3 meters depth without effort. The ballast is variable depending on many factors such as scuba diving weight belts equipment, the thickness of his suit, the volume and type of his scuba diving weight belts block, density, body experience, the salinity of the water, etc. A typical exercise for determining the ballast necessary for divers bottle is in the final dive, stay on the surface with the vacuum jacket. The water level must reach the middle of the mask. To adjust the weights, it is necessary, with guidance from another diver, add or remove weights to progressively refine its buoyancy scuba diving weight belts. Hunters submarines and snorkelers tend to resolve them their ballast to obtain neutral buoyancy at the average depth at which they operate, knowing that for safety reasons they are generally not recommended to be sealed too. To optimize the scuba diving weight belts / volume of ballast, it is often made of lead. These weights are generally small blocks of 500 g, 1 kg, 1. 5 kg or 2 kg. Weight belt: belts that are about 5 cm wide, which attach with a quick fastening system around the waist. It removes up and shot at will. This type of belt can be fitted with small pockets, such as pouches, which are housed in the pellets. shot bags: more versatile, they slip into the pockets provided for this purpose, the buoyancy compensator. A Velcro closure system lets them down quickly. Ankle weights: they set into bracelets around the ankles and help maintain a horizontal position. They are little used because tiring to use when kicking, which is a factor increasing the oxygen consumption scuba diving weight belts. Drysuit divers use them to keep a neutral attitude of the body. belt: used more frequently by hunters submarines, it generally consists of two shot ventral and dorsal plate lead to better distribute the ballast and thus relieve the kidneys. professional divers (diver) use for their shoes heavily leaden ballast to be able to move and work more easily at the bottom. during the descent, if the ballast is too large, the diver will tend to sink and will not necessarily have the time to properly perform its balancing maneuvers. He then accident risk to the diver. if the ballast is too large, the diver will need more effort to stay above the bottom and moving, it may consume more air and thus to miss the end of the dive, and it is also to thank you for breathlessness. if the ballast is not large enough, it can be driven to the surface, exposing it to practice scuba diving decompression sickness, or even a burst lung. during ascent, in addition to the risks mentioned above, increased by the proximity of the surface and greater pressure variation, the scuba diving weight belts diver can also, if deficit ballast failing to keep his or her bearings decompression and risking decompression sickness due to a too rapid ascent. In the event of an accident under water during a scuba diving, if a teammate fails to back his victim and he relieves his belt (or its weight system), the two divers could being dragged to the surface without being able to control their ascent. Therefore, in any other case, a ballast must be removed at the bottom on pain of risking a "rise ball. " For cons, the snorkelers can still in them without any hesitation or dump their ballast that of a teammate in need scuba diving weight belts.

Typically made of neoprene, and there are different types (wet, dry and semidry), with its primary objective the protection against the cold, avoiding hypothermia, in addition to serving as shock protection against accidents, scrapes and punctures. Usually made of rubber or silicone, which is intended to bring an air space between the water and eyes to see clearly through it, preventing the entry of this addition to the nose and eyes, avoiding irritation or infection. The lens should be made of tempered glass, shatterproof or organic high resistance. There are different models and sizes, usually made of rubber or silicone and its purpose is to increase power efficiency and low water activity, reducing diver effort. The scuba diving weight belts belt webbing usually constructed, is intended to offset the positive buoyancy of the diver, produced by the human body and the neoprene suit to obtain neutral buoyancy scuba diving weight belts. The belt must have quick release buckle, in order to cope with any emergency you can drop in easily. The belt should be above any team. Container used to store high pressure compressed air, which allows the diver to breathe underwater. There are different materials (aluminum and steel) and capacities (18, 40, 50, 71. 2, and 80 cubic feet). Must be certified by a competent body of the area recognized by the State of Chile and hydrostatically tested every 5 years. In addition to annual visual inspection. There are compressors of low and high pressure. The former are used in semi-autonomous scuba diving weight belts equipment and others are used to carry air bottles and banks. Equipment for reducing high pressure compressed air contained in a scuba diving weight belts diver's air supply according to the depth you are. It works through an auto demand scuba diving weight belts. First stage: one to the cylinder valve. It has low pressure (120 to 140 psi) and high pressure (where it connects the gauge that measures the pressure inside the bottle). There are different market models and types, allowing the diver to maintain neutral buoyancy underwater, which is achieved by modifying the volume of air, which inflates or deflates. On the surface buoyant inflated to be positive. Descending be deflated to achieve neutral buoyant. It also can be inflated as a last resort in an emergency. scuba diving weight belts knives should be made of corrosion resistant material and its main function is to cut ropes or algae present danger. The knife should be carried in a sheath with straps, which must have insurance to prevent loss involuntarily. Are time records versus depth, which allows you to plan a scuba diving weight belts operation and determine a decompression program, if necessary. Its goal is to eliminate the residual nitrogen in the body. Should be graduated in meters and protected by a waterproof material scuba diving weight belts. There are different market models and types, which should be waterproof and able to withstand a minimum pressure of 100 meters under water, and aims to control the dive time. An instrument used to measure water depth. Must be mechanical or digital and be calibrated to give readings, preferably in metric units.
