Wetsuit

A wetsuits primary function is for conserving warmth. Made from neoprene, wetsuits preserve body heat by trapping a layer of water against the skin through the material. This water warms up because of the body heat and acts as an insulator. Unlike dry suits, wetsuits are not good insulators against very cold water but they are a decent protection from minor changes in water temperature at different depths and are available in different thicknesses making them suitable for diving in different water temperatures.

Mask

Masks keep the water out of your eyes and making your underwater view much more clearer.

Fins

Fins are a means for movement and propulsion underwater. Fins are important to help a diver move more easy, navigate and work again currents. When a diver moves easily and effortlessly underwater using good Scuba fins they in turn conserve more energy and therefore using up less of their air supply.

Buoyancy Control Device (BCD)

A BCD or Buoyancy Compensator is a vest like fitted jacket to which the tank is strapped on and worn by the diver. The BCD is connected via a hose to the tank and has air pockets which can be inflated and deflated with a push of a button allowing you to control your buoyancy in the water and also compensating the weight of all the equipment including the tank used by the diver.

Regulator

A Scuba regulator is a device that allows you to breathe underwater. The regulator attaches to the top of the tank and then has a hose connecting it to a mouthpiece allowing you to inhale air while underwater. The main function of the diving regulator is that it reduces the pressure of the air that is stored in the tank from 3000 psi to a safer and more breathable level of 140 psi.

Pressure Gauge

Basically two pressure gauges are used while diving, one gauge that indicates how much breathing air is left in your tank during a dive and a depth gauge that indicates the actual depth of the diver while underwater.

Tank

A Scuba tank is where the air a diver breathes is stored. A common misconception about diving is that a diving tank is filled with oxygen. For Scuba diving, the regular air we breathe is compressed at about 3,000 psi and filled in the tank. It has the same composition of regular air which is around 78% Nitrogen, 21% Oxygen and the remaining other gases.

Weight Belt

A human body is positively buoyant and therefore need weights to help descend and stay underwater while diving. Typically weights are added to a belt that goes around your waist or in some cases weights can be put into your BCD pockets. The amount of weight needed differs from person to person depending on body fat and a person’s natural buoyancy.
