Scuba diving gear used to be very bulky since a long time, but nowadays, the gear is very light and thin, which is a sign of relief to the scuba divers.

A scuba diving gear is mandatorily required. There can be little dependence on luck in scuba diving, and safety norms require that a scuba diving gear similar to the task must be used. The mask is the first item of the gear. The mask has a small enclosure which allows holding of the air for breathing purpose. Besides, it accounts for proper vision and restricts the entrance of water into the eyes or the nose. A good mask must be tight-fitting and sealed on the face, which retains the air inside, and restricts the water from outside. For proper and a clear vision, the glass must be scratch-proof.

Fins are another part which is necessarily required in a scuba diving gear. They make movement under water much easier. Fins are available in several kinds. While some are made for the professional divers, others are made for the casual divers who dive for recreational purposes.

A weight belt is another item of the scuba diving gear. The buoyancy of the scuba divers tend to increase due to the wetsuit worn by them, and a weight belt can help the divers go to greater depths in the water easily. A buoyancy jacket is generally used by some divers which throws out any water which has entered the wetsuit, and replaces it with air to increase the buoyancy in emergency purposes. The supply of the air comes from the tank generally fitted on their back or from an emergency air supply meant for this jacket. In case of an emergency, the weight belt can also help the diver to return back to the surface. For this, the diver can simply remove the belt.

However, an Aqualung is the most important item of the scuba diving gear. It has 3 parts. First, the air cylinder, which is made of aluminum/steel and about 200 bars of air is compressed into it. Second, the regulator which is a crucial item to make an adjustment of the air pressure with that of the water's pressure to permit the air to enter the mask when required. Harness is the third item, which is used for fastening the air tank to the scuba diver.

Proper operation of the gear and its maintenance must be given due importance by the scuba diver. Prior to diving, the diver must be fully accustomed to the usage and operation of the gear. He must also make sure that the gear is in the fittest condition. Since the diver is ?diving? into a hostile world, he will be at a big danger if the gear fails to work as expected.
