SCUBA – an audacious acronym that stands for, Self Contained Underwater Breathing Apparatus. It is one form of underwater diving in which the diver uses this particular apparatus to breathe underwater carrying their own share of oxygen supply, usually compressed air, which allows divers to venture for longer the wonders of water than snorkeling or free diving ever allowed. The diver usually swims around and channelizes movements with the help of swim-fins attached at the feet, though external momentum can be provided through sled or underwater vehicles if needed.
Buoyancy aids on the other hand are the special personal floatation devices used commonly by canoeist and divers etc. The purpose of their special design is to assist floatation rather than saving lives. They were designed keeping ease of mobility in mind. They do not restrict the range of movement of divers nor do they exhaust or hurdle efforts. The idea for such a set was first developed by Alexander Lodygin. Though it was later worked to perfection by many, it was his dream that allowed us to discover the joys of gliding through the undersea kingdom that seemingly appears effortless. However in truth much practice is required to maintain a balance of buoyancy, weight, breathing and movement.
The first and foremost exercise is that of breathing which is the fundamental of life. Divers have to grip well to the idea of breathing and are taught the best breathing patterns to inhale and exhale slowly and deeply. This breathing pattern allows divers to maintain a constant position while putting in lesser effort. In order to maintain perfect buoyancy relaxed mental attitude is crucial. With the help of buoyancy aids a diver has better control to balance their depth, which enables them to move around the sea bed without damaging the delicate coral life. The divers must exhibit low-impact, hands-off techniques to avoid marring the undersea marvels. The use of scuba diving equipments is also very helpful for the seasoned divers.
Another important skill for a diver to learn id the fin pivot during which a diver descends to the bottom and lays face down in the sand and empty their BC. The diver will then take a full breath and hold it and inflate their BC till their bodies start to float. Upon which, the diver will exhale and sink slow back to the sand.
With the help of buoyancy aids divers are checked for proper weight before going underwater. This requires divers to take a full breath and empty the air from their BC. If the divers have the apt weight they will come to float at eye level with the waterline. However if they do not weights can be tempered with, till the right one is achieved.
