What is self-contained underwater breathing apparatus?

Self-contained underwater breathing apparatus (SCUBA) is a type of equipment used by divers to breathe while they are underwater. SCUBA gear typically consists of a compressed air tank, a regulator that converts the high-pressure air in the tank to breathable air, a buoyancy control device that helps divers achieve neutral buoyancy, and a wetsuit or drysuit to protect the diver from the cold water and provide buoyancy.

SCUBA diving allows humans to explore underwater environments that would otherwise be inaccessible. This includes coral reefs, shipwrecks, and even the ocean depths. However, diving can be dangerous if not done properly, and training and certification is required to use SCUBA equipment safely.

The history of diving dates back to ancient times, but the first practical SCUBA gear was developed in the 1940s by Jacques-Yves Cousteau and Emile Gagnan. Advances in technology have since made SCUBA diving safer, more accessible, and more comfortable for divers around the world.
