There is much to learn about with scuba equipment when you are just getting started in this exciting sport. When you go diving, you will soon see that specialized gear is often necessary for certain scenarios ranging from deep water dives to shallow excursions. But let's keep this to the most widely used equipment with recreational diving most people do. Individuals or couples that enjoy the ocean tend to rent the equipment that they require while they vacationing or have some time off. That is fine and it can be safely done, but you really should understand what you are using and getting. Someone may actually realize that using unknown diving gear can be quite perilous. As you probably have guessed, the more familiar you are with various types of scuba equipment, the safer you will be when using it.

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. A rebreather configuration or closed circuit set-up will last for a longer duration than an open situation. 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. One could find many more divers wearing dual cylinder backpacks in decades past. However, today that is not as common as the single cylinder configuration. 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. As you may have guessed, the second stage regulator is found in the mouthpiece which is the demand valve.

By making simple adjustments, the amount of air that the diver needs is regulated and adjusted. Divers can immediately get access to low pressure and high pressure components and devices on their mouthpiece. Whether you are looking at breathing normally through your mouth, or three or diaphragm, each device provides a solution to make life easier.

Technical diving is a captivating field and in our estimation not for rank beginners. Different scuba equipment that have to be had for this, are numerous containers of special gases. One type of gas, Trimix, is used at deeper depths only, for example. Pure oxygen can be taken and carried and used at decompression stops and ascent. Obviously the extra cylinders can present special problems for achieving proper buoyancy. Technical divers don on high capacity buoyancy compensator (BC) for this reason. Many more things can be discussed and thought about regarding the gear for scuba diving. It is possible to get help from internet sites you can trust such as PADI or your diving instructor if you are a beginning diver. Starting by deciding on where you intend to dive is the best way. A lot of what will be required depends on the way the water is so this needs to be a priority.
