The word scuba comes from the acronym Self-Contained Underwater Breathing Apparatus, which is exactly what this form of underwater diving involves. It allows divers to explore deeper and longer than free divers, as well as allowing them to enjoy breathing air that is not coming from the surface (though many scuba divers use a blend of oxygen rich gas known as nitrox).

Besides being able to spend more time underwater than with surface-supplied free divers, scuba also lets you peer closely at tiny sea creatures clinging to the edge of a reef or gaze out over a shoal of glimmering fish. It’s the ideal way to take in the sights and sounds of the underwater world.

For these reasons, scuba is immensely popular with recreational divers. It has become a worldwide pastime, with people of all ages and backgrounds taking up the sport.

In order to scuba dive safely, you need to meet some minimum requirements. You will need to pass a knowledge development course, complete some confidence water dives and then demonstrate your ability to safely conduct open water dives. Those who wish to progress further can go on to earn their advanced scuba certification, or even further specialise in areas like deep diving or cave-diving.

A wetsuit is also essential for any scuba diver, as it is a neoprene body suit that keeps you warm and comfortable while underwater. You will also need to wear weights – either attached to a belt around your waist or in quick-release pockets in your BCD (Buoyancy Control Device). Finally, you will need a tank of compressed air and your dive equipment.
