Diving Equipment

Diving Equipment includes numerous items and is imperative to the sport of Diving. People have been diving since ancient time, and in those days it involved divers going after sponges.

In today’s world people dive for recreational and work purposes. When diving you are always going to need certain equipment. Things like masks are a must, but other items like snorkels or swim fins are usually need as well.

Other items include flashlights which are essential for safety in low visibility or dark environments such as night diving and wreck and cave penetration. They are useful for communication and signaling both underwater and on the surface at night.
Divers need artificial light even in shallow and clear water to reveal the red end of the spectrum of light which is adsorbed as it travels through water.

Some divers want to go deep, so those people usually use a scuba set to accomplish their tasks. A scuba set is an independent breathing set that provides a scuba diver with the breathing gas necessary to breathe underwater during scuba diving. It is much used for sport diving and some sorts of work diving.

Both types of scuba provide a means of supplying air or other breathing gas, nearly always from a high pressure diving cylinder, and a harness to strap it to the diver's body.

Most open-circuit scuba and some rebreathers have a demand regulator to control the supply of breathing gas. Some semi-closed rebreathers only have a constant-flow regulator, or occasionally a set of constant-flow regulators of various outputs.

With rebreathers, the gas the diver exhales is stored between breaths in a counter lung. In some rebreathers, one-way valves direct the gas through a loop. In other rebreathers, the inhaled and exhaled gas goes back and forth along a single tube: this is called the pendulum system.

The oxygen consumed by the diver is replaced, nearly always from a cylinder. The exhaled carbon dioxide generated by the diver is removed by passing the gas through a scrubber a canister full of soda lime, making the gas fit to be re-inhaled. This type of scuba equipment is known as closed circuit.
