Understanding Scuba Equipment And How It Works
Wednesday, July 20th, 2011If you are new to scuba diving, you need to learn a couple of things about this type of equipment before investing any of your money. Most importantly, do not buy things on impulse and make sure you know exactly what you need before you bring it all home. This warning is only for those that are impulse buyers; if you know what you need, go get it right now. An example of understanding which piece of equipment you need can be knowing what diving fins you will need because of where you will be swimming. A comparison would be cave diving opposed to open water diving; each type of dive requires a different size format of the fin itself. Diving in waters that are deep where you need extra mobility will require fins that allow you to stop, go abruptly and travel fast. Basically, the purpose of your dive will always be in direct proportion to the equipment that you will need to use.
If you are thinking about scuba diving, there are two basic types of equipment that you will need. People that are not sure which type of equipment configuration to get can usually answer their own question by figuring out where they are diving and what they are going to do.
For recreational divers, the open circuit set up is the most common. Semi closed circuits, and fully closed circuits, are representative of the rebreather configuration. Although closed circuits were the original, open circuits are now the most popular. In the closed-circuit, the diver will breathe back into the equipment, and then the exhaled gas is made fit to breathe again.
A single setup hose is used with open circuit configuration instead of multiple hoses. The single-hose regulator set-up will have a two stage regulator design for reducing the high pressure cylinder gas which is the first stage regulator. The mouthpiece actually houses the demand while it acts just like a second stage regulator.
By making simple adjustments, the amount of air that the diver needs is regulated and adjusted. 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 a one-way diaphragm.
A dive computer is a high-tech piece of equipment that almost all divers are aware of. This device is very clever in that it shows your ascent rate as you rise to the surface, allowing you to compensate or slow down if you’re going too fast which will, inevitably, give you decompression sickness upon arriving. 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. Using a combination of understanding how deep you are, and utilizing the inert gases in your body, it is able to make constant predictions as to when you need to slow down or speed up. Although there are many more calculations and computations that this device can do, it depends on where you are diving and what you need to be displayed. There is so much more to discuss and consider with the subject of scuba equipment. Provided you are a beginner, you can get numerous tips from websites that you trust like PADI or your diving teacher. Making a decision about where your diving location will be is the best starting point. Since what is necessary is contingent on what the state of the water is, this is vital.
