What is Scuba Diving?

SCUBA DIVING

Scuba diving is a form of underwater diving where a diver uses a Self Contained Underwater Breathing Apparatus “SCUBA”. Unlike other kinds of diving, a scuba diver does not need to hold his/her breathe or rely on air pumped from the surface. Scuba divers use their own gas for breathing underwater. Using their own gas tanks, freedom and longer underwater endurance than breath hold, a diver can enjoy his/her time diving. Usually, the gas consumed by divers is compressed, dry air. There are others kinds of gas mixtures that divers use for diving. Those special mixtures are usually used by technical divers or for special kinds of underwater activities. Most people have the idea in their mind that the gas consumed underwater is pure Oxygen, which is a wrong idea. Pure Oxygen gas is considered to be lethally toxic after exceeding the depth of 6m. The gas consumed by a normal scuba diver under water is normal air that we as human breath in our normal conditions. Another inquiry that lots of people have is the question “How long can I stay underwater using a single tank?” The answer of this question depends on many factors such as: 

• The first factor is the water temperature. When the water is cold, a diver consumes more air than in worm waters. 
• The second factor is the depth of the diving site. A scuba diver consumes more air in deeper sites than in diving in shallow waters.
• The third factor is the diver`s physical fitness. When a diver is a non-smoker and is in a good physical shape, then he/she consumes less air than smokers or divers that are not in a good physical shape.
• One more factor is the type of underwater activity. When a diver is taking photos and not moving a lot underwater then he/she consumes less air than a diver that is moving all over the place. 

Useful advice's about air consumption 

There many ways for a diver to control his underwater breathing. I have chosen two good articles, article one is and article two is written for you to read more about this topic. Those are the links to the articles:
