It?s not hard to be seduced by the cool looks of scuba gear when you?re new to diving. You can become confused and disheartened as to what to choose. Modern wetsuits don?t just come in ?basic black.? It?s easy to stand out from the crowd with the many choices of wetsuits available and proclaim your fashion sense to the world. The top priority for the majority of divers when they search for new gear is not fashion, but the caliber and dependability of the equipment. 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. If you can?t see the inner workings of a piece of gear to make sure they are still functional, you may not be making a wise purchasing decision. Our best advice is for you to always purchase equipment and gear that is new until you?ve been around diving for a while and have the knowledge to choose quality used equipment.
An important piece of scuba diving equipment that you need to be familiar with is called a demand regulator. Basically, one or more cylinders are used to contain the air that you are going to breathe with underwater. These cylinders are very important because of the high pressure air within them that is accessed by the diver through the diving regulator. The purpose of the demand regulator is to provide air to the diver at an appropriate pressure level so that they can breathe. The position of the diver also factors into how this works.
Open circuit scuba diving usually involves the diver wearing one gas, or air, cylinder and all the associated components and devices. You will find that open circuit diving will not last as long as diving with a rebreather configuration, or closed circuit set-up. A few, and probably the majority of those that dive on a recreational basis, will make use of the usual air mix which is 21 percent air and 79 percent nitrogen. Dual cylinder backpacks were worn my more divers decades ago. Presently however, this isn?t as popular as the configuration of the single cylinder. You will discover more divers wearing twin backpacks with the kind of diving characterized as technical diving. There is an old-style design that is called the twin-hose configuration, and that was the very first design for a demand valve to achieve widespread use. It is not surprising that this set-up also made use of twin cylinders. This design features a large circular valve assembly that, at least in Europe and America, was fastened to the top of the cylinders with an A-Clamp. 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. Extreme care had to be exercised during the design phase to adequately address any potential safety issues. For example, most units have a one-way valve placed into the mouthpiece to keep air or water from going into the inhalation tube.
There is a good chance you are familiar with the term BCD or BC ? buoyancy control device. Wing BCs attach between a diver?s back and the cylinders and are especially popular with technical divers who may have the need to carry many cylinders. Another design element is to create a connection to the air, or gas, so the device can be easily and quickly inflated if so desired. The main component of the BCD is the inflatable bladders that can be inflated/deflated either manually or via a connection to the air or gas line. When the device is inflated, the overall volume of all the equipment will increase as necessary for the desired effect.
Once you begin to use complex scuba equipment, this will open the door to other aspects of diving. The more specialized gear is used for divers certified for specific purposes such as dry suit diving, cave diving and diving at greater depths. Between the military and high-tech industry, specific situations have developed over the years requiring more research and development. Scuba diving is a fascinating sport that can provide many years of constant learning and exciting experiences.
To be certain, scuba diving needs a large amount of gear. That?s why many people who?re seriously interested in this wonderful activity have huge automobiles. When you?ve got a large passenger van or SUV, you can not only carry all your scuba gear, but your friends and family as well. Why not get a van or SUV today to ensure that aspect of your hobby is looked after?
