The best way to get this knowledge as soon as possible is to take a certified diving course to learn the basics.
Retention of what you are learning from your instructor is often tested at the end of the course to see what you actually know. So you will have lots of opportunities to ask questions if you need help with anything. But let’s take a look at just a few devices that are part of the scuba equipment you may need.
An important piece of scuba diving equipment that you need to be familiar with is called a demand regulator. There are cylinders that are used to contain the air that you breathe. 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. Other factors such as the depth or level that the diver is at modify the end result. The twin-hose scuba demand valve was the first demand valve to be put into general use. Although Cousteau started his design with just one tube, that didn’t work well and he had a second tube added. The valve assembly was rather large and circular and was fastened to the top of the two cylinders. The second tube wasn’t for the purpose of rebreathing, but for exhalation to return the exhaled air to the regulator. When the equipment was in the design stages, special factors had to be addressed to ensure the equipment would operate safely. For instance, the exhalation tube needed to be in close proximity to other devices to prevent gas from flowing without restriction.
Due to the fact that it is so important to have water buoyancy, scuba divers use weights to help maintain the equilibrium. The amount of weight that you use will be between 5 pounds and 33 pounds. Similar to sitting on an inner tube, there is a way to determine a buoyancy level which more than likely has to do with adding additional weight.
Neutral or negative buoyancy are very common depending upon the type of tanks that the scuba diver is wearing. Until recently, blocks of lead were still tied to the waist belts of divers. You should always add several nylon bags with lead shot within them so that you can find your buoyancy level very quickly. The weighted bags can be placed inside the buoyancy compensator device.
The dive computer, and other scuba equipment, is very necessary when trying to achieve a safe and productive dive. Excellent advances have been made with technology and design to make this type of dive gear available. This is one piece of equipment that we would recommend buying and not looking for the cheapest model, either.
