What is the purpose of scuba gear?

What is scuba gear? Scuba diving equipment allows you to visit the underwater world by making it possible to breathe, see and move comfortably while below the surface. Gear helps you change from being a land-dweller to somewhat of an aquatic being – if only for a little while. A mask lets you see clearly.

How was the scuba gear invented?

Invented modern scuba gear

In 1942, Cousteau and Gagnan co-invented a demand valve system that would supply divers with compressed air when they breathed. This modern demand regulator was named Aqua-Lung and its invention eventually opened the door to diving for anyone who was interested.

What is scuba gear made of and why?

Wetsuits are made of neoprene rubber, a closed-cell foam that traps millions of tiny gas bubbles within its structure. Unlike open-cell foam (i.e., a sponge), water won’t saturate neoprene, but the gas bubbles tend to give the material a lot of inherent buoyancy.

What is the most common injury in scuba diving?

The most common injury in divers is ear barotrauma (Box 3-03). On descent, failure to equalize pressure changes within the middle ear space creates a pressure gradient across the eardrum.
