Scuba-diving

Scuba-diving is gaining in popularity and is practised all over the world, but to be practised safely  good equipment is essential! 🙂

Scuba-diving equipment  is divided in two parts:

Heavy equipment, which consists of:

– a diving cylinder – a container made of aluminium or steel inside which a mixture of gas is kept under pressure, from 30 atmospheres to a maximum of 500 atmospheres;

– a breathing regulator, which is composed of tubes that connect the cylinder with the mouth-piece with which one breathes;

– a BC or BCD (Buoyancy Compensator or Buoyancy Control Device) which is usually a vest, equipped with weights, that helps control the different stability underwater.

Light equipment, which consists of:

– an underwater mask;

– fins;

– socks, which keep you warm and make fins more comfortable

–  a wet-suit, which keeps you warm

– a snorkel, which can be useful in case of emergency

– a surface marker buoy, which lets boats know that there is a diver under water.

Before the invention of the gas cylinder and the mouth-piece, diving was very dangerous and only possible after a long and hard training!

In 1943 Jacques Cousteau invented the Aqua-lung, which was the first name of the breathing regulator, and which is composed of two parts: the first is attached to the oxygen tank and it reduces the pressure of the out-coming gas, and the second is in the mouth-piece and it controls the emission of the air.

In English diving with this equipment is called SCUBA – diving where SCUBA is an acronym invented in 1952 meaning:

Self Contained Underwater Breathing Apparatus

And it has been called so up to this day.

  1. I think that it’s wonderful to explore the seabed: the only thought gives me the shivers… but it also scares me! Perhaps i’ll never be brave enough to “scuba-dive” 🙂
