The Scuba BCDControlling a Diver's Scuba Buoyancy
Because divers can not naturally adjust their ability to float Scuba BCD's, or Buoyancy Control Devices are an essential part of a scuba divers equipment. This jacket style device helps divers control their buoyancy while on a scuba dive. In addition to buoyancy, it is where the rest of a divers gear is secured. A scuba bc will have a harness to secure a dive tank, pockets and clips to attach a divers gauges and octopus.
The Purpose of a Scuba BCD and How It WorksA BC provides flotation at the surface. This helps a diver rest at the surface before descending or after ascending. When properly inflated, a BC will keep a divers head well out of the water. An inflated BC also makes it easier for a diver to make a surface swim to their exit point after a dive. While diving, divers can add small amounts of air to fine tune their buoyancy. By filling or emptying small amounts of air, divers can become stationary at a desired depth. This is neutral buoyancy, perfect balance underwater. Knowing how to properly use a BC to achieve perfect buoyancy control in scuba diving means a diver will use less effort and air while diving. BCs can also reduce buoyancy. By emptying air from the BC, a diver can make a slow, safe ascent. A deflation button is located at the end of the corrugated hose. Divers can also empty air from the BC by pulling a cord attached to a dump valve. There are two ways to inflate a scuba BCD. The BC in connect to the scuba tank via a low pressure hose on the scuba regulator. This hose connects to a corrugated hose on the left shoulder of the BC. At the end of the hose is the automatic buttons for inflating and deflating the BC. Also at the end of the corrugated hose is a mouthpiece that allows the diver to inflate the scuba dive BC orally. Choosing a BC for ScubaBuoyancy Control Devices come in several different styles. This enables each diver to find just the right scuba bcd. The most common type is the "Vest" or "Jacket" style. This is worn like a jacket or vest with the inflatable bladders on the sides. There are two over the shoulder straps with quick release clips. Across the mid section the is a cumber bun and or strap with a quick release clip. This jacket or vest style enables divers and all their gear to float comfortably at the surface in the head up, feet down position. 
Another type is the "Wing" style. This scuba bcd has the inflatable bladders on the back of the jacket instead of on the sides. This style enables divers to swim at the surface with all their gear in a face down position When choosing a buoyancy device, fit and comfort are very important. If the jacket is too small, it is difficult to inflate without restricting your breathing. If the jacket is too large, it becomes very sloppy underwater. The tank is all over the place. One minute it's banging you in the back of the head, the next minute it's under your arm. A jacket that is too small or too large makes for a very uncomfortable dive. Your buoyancy device should fit like your best coat. Not too tight under the arms or around the shoulders. Just a little snug across the belly. Divers can feel when their bc jacket fits just right. They can inflate the jacket to float comfortably at the surface with all their dive gear or adjust their buoyancy underwater and never loss the comfort or fit of the jacket. And ladies, there are scuba bcd jackets made just for you. Most all manufacturers have designed buoyancy devices for the shape of the female body. Another thing to look at when buying a buoyancy device is lift capacity. Proper lift capacity allows divers with all their dive gear to float at the surface with their head comfortably out of the water. This will differ from diver to diver based on body weight, density, and the amount of weight (to include weight belt, camera, flashlight,etc.) each diver carries. Maybe it's the basic "jacket" style. Perhaps it's the more expensive "weight integrated" style or even the top of the line all-in-one integrated BCD/weights/breathing system that works for you. With all the choices, a diver can easily find the right scuba bcd. Just remember these basic tips when looking for the right buoyancy jacket.
Maintaining a Scuba Dive BCProper care of a BC will keep it in good working condition for many years.
