Who wouldn’t desire to explore the world under the sea? Humanity has always been fascinated by marine life. Because of this great fascination extensive reasearch and amazing inventions amazing have given us a chance to breathe underwater so that we can observe and have fun exploring the depth of the ocean.
However, underwater scuba diving isn’t simple as filling a tank of air and taking the plundge. There are a lot of things you need to consider. Being underwater is alot different than being on land.
The air pressure is alot different from the pressure of the water. The human body isn’t adapted to high pressure changes. Controlling your buoyancy and preventing the loss of body heat when underwater are major considerations.blue water scuba diving image
Fortunately, probably every thing a underwaterscuba diver needs to explore the deep ocean is available. There is the mask, snorkel, fins, regulators and diving suit to name a few. This gear allows the underwater scuba diver to breathe, control of their position and keep warm under water.
In order to breath under water, an underwater scuba diver wears a metal tank filled with compressed air. A regulator is attached to the tank, which regulates the air pressure to correspond with that of the environment so that the underwater scuba diver can breathe comfortably. The regulator provides air through a mouthpiece which uses the plunger to inhale and exhale. Another hose is connected to a regulator to control the diver’s buoyancy. It is attached to an air bladder, which is adjustable. Since the underwater scuba diver wears this as a vest, adding air into it would make him more buoyant, and thus, he rises. When he releases the air, the opposite happens.
These buoyancy compensators help a under waterscuba diver achieve neutral buoyancy. When you are in the neutral buoyancy, you can stay at a constant depth without too much effort. This minimizes gas consumption because of swimming. underwater scuba divers also wear lead weights like a belt to allow them to descend and remain under water. The weights are evenly spaced in order to achieve equilibrium. During emergencies, an underwater scuba diver can just quickly release these belts to rise to the surface.
A scuba diver’s wet suit is really incredible. It is composed of compressible substance, so when one goes down, it reduces the volume, and when you go up, it expands. They are very useful to manage ones buoyancy.
A cold water scuba divers suit also provides thermal insulation. A wet suit, for example, is usually neoprene which has bad thermal conductivity, which minimizes the loss of body heat to the surrounding water.
Another way in which a driver’s suit can reduce the loss of body heat is by trapping a layer of water between the suit and the cold water scuba diver’s skin. The combination is very well sealed at the neck, wrists and legs so the water flow is reduced. This technique in reducing heat loss is known as convection, which is the same principle used in the concept of semi-dry.
A dry suit on the other keeps the cold water scuba diver dry, as apposed to a wetsuit. Generally the water will not penetrate the dry suity. Preferably, dry underwear are worn for better insulation. A dry suit traps thin layers of air, which keeps the cold water scuba diver warm. Of course, to familiarize yourself better with cold water scuba diving gear, it would be best to take scuba diving lessons . You can get yourself certified by passing a scuba diving course. In the course, you’ll not only learn about scuba gear, but you’ll also be taught how to scuba dive safely.
During the course, student scuba divers learn how to achieve neutral buoyancy. Through various swimming exercises, they will also learn how to control their breathing rate. A cold water scuba diver should know how to breathe in a slow but continuous manner.
At the end of the course, you are expected to know some safety procedures in diving, such as how to clear your mask if in case water leaks in, how to avoid any mishaps while underwater, and of course, learn to help a fellow cold water scuba diver in need. Conventional hand signals are used underwater to communicate since scuba divers don’t have another way to talk to each other.
By being a certified underwater scuba diver, you can refill your air tanks, buy underwater scuba diving gear and scuba dive anywhere in the world. underwater scuba diving businesses require this certification as proof that you can well manage yourself underwater.
Of course, to be able to better familiarize themselves with these underwater scuba diving gear, it would be preferable that you obtain certification by passing a course in diving. In this course, you will not only learn about the equipment, you will also be taught how to adapt to the dive.
