Scuba diving refers to swimming underwater while using self-contained breathing equipment. Other swimming underwater activities such as free-diving or snorkeling use breath-holding techniques. Scuba diving in contrast, involves having a compressed air source, which means that the scuba diver can remain submerged for a longer period of time and he/she is not hindered by a remote air source.

The term ‘SCUBA’ is the acronym for “self contained underwater breathing apparatus”. However, the term now refers to ‘scuba apparatus’ or ‘scuba equipment.’ The term owes its origin to World War II days, when it came to refer to the oxygen rebreathers used by US combat frogman in underwater warfare.

Scuba diving typically involves swimming underwater with fins which are attached to the diver’s feet. However, there are other options for scuba divers to move around, such as the diver propulsion vehicle or sleds pulled by a boat. The latter are surface tethered devices.

Many people unfortunately, believe that scuba diving is an extreme sport, and impression is dispelled as soon as one gives scuba diving a try. The wearing of a diving suit provides protection. This diver suit helps avoid skin cuts that could be caused by corals, marine animals or underwater objects. They also prevent the loss of body heat.

Contrary to popular belief, scuba diving doesn’t require a substantial physical effort on the part of the diver. Therefore, we could say that anyone who can walk a few miles can successfully complete a scuba diving session. Although it’s underwater, scuba diving does not require excellent swimming abilities, but some certified scuba divers may be required to possess swimming skills, just to check the extent to which they can adapt themselves to water.

There are many reasons why scuba diving is gaining widespread popularity. First of all, it is an excellent opportunity for those interested in marine life, to be close to it. In fact, the sheer variety of underwater wildlife, coral reefs and the numerous species of colorful fish will make the experience memorable for any scuba diver.

In addition, scuba diving offers a wide scope for studies, researches and investigations. Marine biology, for instance, has seen great progress with the help of scuba diving. Most importantly, scuba diving is a relaxing activity, enabling one to de-stress in a soothing environment. The educational advantages are an added bonus.
