One of the primary diving talents a new diver will have to contend with in the course of her scuba diving coaching is the mastery of buoyancy control. Now there are three factors affecting the scuba diver’s state of buoyancy – particularly the diver’s weight, breathing techniques applied and naturally the sort of buoyancy compensating device or BCD used. The article will briefly debate how weight and breathing issues can affect diver performance while a rundown of important BCD functionalities will be featured. Likewise, some tips important to the selection and use of said scuba gear will follow.
Body Fat is Buoyant. True! Packing extra pounds to your weight makes you more buoyant than the scuba diver with the standard Body Mass Index ( BMI ). To boost buoyancy control, the overweight scuba diver should implement life changes to rid excess fat and work on the increase of muscle mass instead. Fat is less dense than either the muscle tissues or bones and will so lift the diver back to the surface, especially when diving in seawater.
Think of it this way, to sink that tookus of yours, you have to wear more lead to get down to depth , when you wear more lead, you pump more life giving air into you BCD, when you pump life giving air into your BCD, you shorten your dive time. . . . get the picture?
Correct Breathing is essential. The diver won’t be ready to attain a horizontal, face down position on the water column without implementing correct breathing techniques relevant to neutral buoyancy. The human lungs are plentiful with air – filling its cavities, and this applies an opposing force ( buoyancy ) against the diver’s weight. 
Inhalation stuffs air into the lungs to cause the diver to rise while exhalation decreases lung volume , causing the diver to descend. To get efficient control of his vertical direction, the diver should learn to compensate for the opposing forces of buoyancy and weight ( thru the concurrent application of breathing techniques along with BCD and lead weights operation ) so that the diver neither rises to the surface nor drops to the bottom , but rather stays at a particular depth on the water column.
BCD Facts and Tips. The more costly buoyancy compensator devices are provided with functionalities that support its reinforced performance. So if you’d like to be spared from the determined inefficiencies of the bladder stabilizing vests of less expensive BCDs, then settle for no less than the mid-range line of this scuba gear that are likely featured with an integrated weight system. Inexpensive BCDs have been found to trap volumes of gas despite venting and these air spaces meddle with the diver’s buoyancy position. When buying a buoyancy compensator device, be certain to establish the lift capacity of the device since recounted information will help you set your buoyancy before the dive. Similarly check its construction and accept a BCD that gives a convenient reach of pressure release valves and accessory pockets while equipped with quick release, adjustable straps. In terms of style, technical divers prefer the Wing type BCD over the Vest type given its capability to easily assume a face-down, hovering position on the water column.
