Are you a newcomer to scuba diving? If so, I’m sure that the first time you went shopping for diving gear it was easy to be lured by all the great colors and avant-garde designs. You can really make a fashion statement with your wetsuit, alone, if you wanted to do that. The main focus for most divers when they’re are buying diving equipment is to buy the best quality and most dependable gear they can afford. 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 are thinking about buying some used equipment that has inner pieces that you can’t see, you may be heading for trouble if these parts are weak or damaged. Personally, we always recommend buying new at least until you are at the point where you have enough experience.

For the most part, scuba divers who dive in the open circuit, shows the diver attired in an air or gas cylinder with every fixture that is part of it. One will discover that open circuit diving is not as long as when you are diving with a closed circuit set-up or rebreather configuration. Numerous if not all of the recreational divers apply an air concoction of 21% oxygen and 79% nitrogen. Decades ago you could find a higher percentage of divers wearing the dual cylinder backpack. Still, this doesn’t happen as much as the lone cylinder configuration currently. There is a type of diving known as technical diving, and this is where you will see more divers wearing the twin packs.

Multiple hose configurations are often seen on closed circuit configurations, whereas single-hose setups have just one. The one thing you should know about single hose regulator set up is that they have a high pressure cylinder gas which is properly controlled by a two-stage regulator design. The second stage regulator is the demand valve which is found in the mouthpiece.

With just a few small adjustments, each person can figure the demand valve to supply the proper amount of air to the diver. So there is a high pressure component and low pressure devices used immediately by the diver. The diver can actually breathe with the mouthpiece, but can also exhale through an one-way diaphragm.

A dive computer is a high-tech piece of equipment that almost all divers are aware of. Basically, this device monitors how fast you are going up so that you do not get the bends or decompression sickness from ascending to quickly. The dive computer will calculate depth and time of the dive, and it uses that information to produce the ‘safe ascent profile’. It actually does quite a bit, including telling you when to do intervals stops for decompression purposes, and telling you how fast or slow you need to go. All of this data is calculated nonstop as you rise to the surface, even using inert gases within your body to help it make the right calculations. There are other parameters that can be calculated and displayed depending on one’s needs. 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. Not only must you understand how each piece of equipment operates, and what it’s for, you have to know what it will do when you are underwater on a dive.
