Basic Equipment Needed for Scuba Diving

Atomic Scuba Diving Equipment

SCUBA is short for Self-Contained Underwater Breathing Apparatus. The first successful and safe open-circuit SCUBA also known as Aqua-Lung was designed in 1942 during the German occupation of France by Jacques-Yves Cousteau and Emile Gagnan.

Webster’s New World College Dictionary, 4th Edition, defines SCUBA as equipment worn by divers for breathing underwater, consisting typically of one or two compressed air tanks strapped to the back and connected by a hose to a mouthpiece. SCUBA diving is basically swimming underwater using SCUBA equipment. It is however important to note that the SCUBA is not the only equipment needed for a successful SCUBA diving.

The basic equipment for SCUBA diving includes:

Air Cylinder

The air cylinder is perhaps the most crucial piece of scuba equipment as it contains the pressurized air that will allow divers to breathe underwater. Pressurized air is used because the pressure of the inhaled breath must balance the surrounding pressure to allow inflation of the lungs.

This is what scuba divers breathe through when they are underwater. It makes sure the diver can breathe naturally and without excessive effort, regardless of depth. The regulator has two stages; the first stage reduces the pressurized air from a high (300 bar) to intermediate (10 bar) pressure and the second stage further lessens the pressure to ambient pressure for ease of breathing.

Buoyancy Control Device (BCD)

This device allows you to control buoyancy whilst underwater, it is simple a very important part of your scuba diving set. It gives you the opportunity to explore the water at certain depth without needing to exert force by kicking with your fins. This will assist in the conservation of your energy and help you use less air, therefore prolong your dive time.

Scuba Mask

A scuba mask is a specialized piece of equipment designed for scuba diving. It is made out of tough materials that can withstand underwater pressure. This equipment provides a diver with clear vision under water. It also has a future that encloses the diver’s, allowing the diver to equalize the pressure in the mask so it doesn’t suction painfully onto their face.

Scuba Diving Fins

Fins also known as flippers are very important for scuba diving because the fins allow a scuba diver to move more swiftly and efficiently underwater with the least amount of effort possible. This equipment can give divers more time to move around in the water bodies.

Neoprene Wetsuit

A wetsuit’s main purpose is to keep the scuba diver warm whilst diving. The human body loses heat twenty times faster in water than it does in air, and this wetsuit will help slow or prevent that heat loss. These suits regulate the body temperature by trapping a layer of water between your skin and the suit, heating it up to your body temperature. This is to ensure that a diver does not lose too much body heat whilst diving.


Weights are necessary for scuba diving as it counteracts a diver’s natural buoyancy. The gases in your body, your air cylinder, and your wetsuit make you buoyant (light) and thus weights are needed to ensure you stay underwater. These weights are made from lead, a high-density material which can be made into a compact and easy to carry form. They are worn around the waist.
