The introduction of scuba gear (an acronym for Self-Contained Underwater Breathing Apparatus), has redefined underwater diving altogether. Through the advances in technology, scuba gear allows people to dive deep below the surface of the water and still be able to breathe. Opening new avenues for exploration, scuba diving offers unlimited opportunities to unravel the mysteries of the underwater world.
The scuba diving system is the outcome of extensive technological research and innovation spanning almost 300 years. It is now the most widely used system for breathing underwater.
Scuba diving offers the divers unlimited freedom of movement underwater because they swim with fins, minus any heavy equipment. The scuba gear is comparatively inexpensive and simple to operate and maintain. Scuba diving is currently used for recreational diving, as well as for conducting underwater tasks for military, scientific and commercial purposes.
Apart from the conventional mask and fins, a basic scuba set comprises a cylinder of compressed air attached to a two-stage demand regulator. The purpose of the regulator is to lower the air pressure from the cylinder and allocate it to the diver as needed.
