It’s easy to be sucked into the exterior features of scuba gear when you are a beginning scuba diver. This can distract and frustrate you when you want to buy the gear that is perfect for your needs. You can really make a fashion statement with your wetsuit, alone, if you wanted to do that. Practically all scuba divers are more interested in the quality and reliability of their gear than if it’s the hottest color or most fashionable style available today. It may be tempting to buy someone else’s old equipment because it’s less expensive, but it might turn out to be a bad investment. For one thing, with different types of equipment it’s impossible to inspect the inner working parts to make sure they are not damaged or weak. The wisest counsel we can give you, if you are a “newbie” to diving, is to buy the best quality new equipment that you can afford for the time being and, after you have been around diving for a while, you will be better able to judge the merits of used gear.
Once you purchase scuba diving equipment, you should see that two basic types can be utilized. What you need will depend on the application, diving conditions and the purpose of your dive.
If you are purely a recreational diver because you simply enjoy the sport, open circuit setups are probably for you. A rebreather configuration is referential to a closed or semi closed circuit. Closed circuits were the initial type which were later replaced, or at least used more, by open circuits. The difference between a open circuit and a closed-circuit apparatus is that when the diver breathes back into the equipment, the exhaled gas converted to something that you can breathe once more.
Another thing you need to be aware of are scuba diving tanks which are air cylinders for the diver. Typically, these air tanks are made of stainless steel; most of the time they are provided in different sizes to fit the various divers that will use them. As you can guess, there are different diving scenarios and depths for a wide variety of reasons. So the most suitable amount of air provided can be found with cylinders made from different materials. Depending upon whether or not the cylinders are used in the US or Europe, the cylinder designations can be very diverse. Inside each cylinder that is from the United States is one atmosphere of pressure or 1 Atm representing a full tank. While in Europe the reference is given in terms of internal volume.
Deep diving is usually accomplished by technical divers who enjoy going far down usually further than the average diver will go. You must always be on your guard diving too deeply as he can be very hazardous for those that do it. Part of their additional regimen is to have special fixtures in their oxygen tanks, along with redundant systems to provide emergency backup just in case. It is commonplace to see pony cylinders attached to divers that do this type of diving. These are actually a completely separate unit having separate mouthpieces, demand regulators, and hoses on each unit. Used for extreme malfunctions, the primary gas supplies in them will help compensate for a lack of air in the main unit. Make sure to take into consideration the environment in which you will be diving when you select your scuba diving gear. When you are at a dive shop buying your equipment, make sure before you leave that you fully comprehend how each of the pieces operates. In addition to understand the workings of each piece of equipment intellectually, you must also fully comprehend how the equipment will act when you dive.
