There is much to learn about with scuba equipment when you are just getting started in this exciting sport. In fact, specialized gear is definitely necessary depending upon where you are going to be swimming and diving, something that most novice scuba divers are not aware of at the start. The focus of this article will only be on recreational diving which addresses generalized equipment that must be used. It is quite common for many vacationers to rent what they need for a dive. Of course, it is okay to do this, but before you do, it is important that you understand a little bit about the equipment that you’re using. Someone may actually realize that using unknown diving gear can be quite perilous. The more information that you have about SCUBA equipment, the better off you will be in such a situation.
At one time a dive mask may have been the same as, or similar to, snorkeling goggles, but today’s masks are a world apart. Scuba diving masks have really gone high-tech and are pretty impressive with their features and benefits. For recreational use, we discovered that the Neptune Space G.divers full-face scuba mask is representative of the class of masks now in use. The Space G.divers mask comes in two sizes – medium/large and small/medium – and an optional special adaptor is available for connecting various kinds of regulators. Advances and innovations in optics increases the amount of visible light that is passed through the visor to close to 95%. The Space G.divers masks make ear clearing easy with their exclusive, patented 3-D equalization system. The twin-hose scuba demand valve was the first demand valve to be put into general use. Although Cousteau started his design with just one tube, that didn’t work well and he had a second tube added. An A-Clamp was generally used to attach the large, circular valve assembly to the top of the twin cylinders. The important function of the second hose was exhalation that helped the air pressure of the breathing hose stay the same as the outside water. In order to ensure safe operation, there were special design elements that were crucial. The placement of the exhalation tube was one such concern. It needed to be close to the other devices so the uninhibited flow of gas would be eliminated.
The buoyancy control device, or BCD as it’s commonly known, is most likely a term you have heard. Jacket style BCs are the most popular with recreational divers today because they include the BC, as well as weights, places to attach additional equipment, and a place for the cylinders. The BCD needs to have a connection that feeds the gas into the bladders of the BCD, allowing it to be inflated or deflated as needed. In a nutshell, the BCD contains bladders which will inflate either manually with a mouthpiece or when connected to air supply. A diver can adjust the BC to maintain neutral buoyancy by adjusting its volume and, therefore, its buoyancy. The type of scuba equipment you decide to use will be based on your expected diving conditions. Regardless, it’s imperative that you understand completely how each piece of equipment you purchase operates. Also, when you learn how they work, you should make sure you understand how they will affect you underwater.
