What is Scuba Diving?

Scuba diving is a mode of underwater diving in which a diver uses self-contained underwater breathing apparatus (shortened by SCUBA) to breathe underwater. Scuba diving may be the best way for exploring the charming underwater world and its diverse and colorful inhabitants.

Scuba diving was developed by Jacques Cousteau in the mid-1940s, and it has become, since then, a recreational sport that is taken up by millions worldwide.

History of Scuba Diving

Those who live by the coast have been diving insofar as mankind has existed. In the Arab world, pearl divers were diving looking for pearls underwater. People living by the coast around the world were diving for food depending on their driving skills.

Over the years, many advancements in diving arose from the need for navies, and the need for diving equipment has become more sophisticated, although the risks associated with diving still remain.

The popularity of scuba diving grew and it became accessible and highly popular with the masses thanks to the contributions of Jacques Cousteau and Gagnan who helped to make it into the modern world.

Nowadays, scuba diving has safety codes and regulations, and there are organizations for instructing and certifying divers, such as the National Association of Underwater Instructors, formed in 1961, and the Professional Association of Diving Instructors, formed in 1966.

Scuba divers need some gear for a better experience and safe adventure. They should consider the gear fitting them best. This scuba gear includes:

Scuba Diving Masks

A scuba diving mask is a basic piece of gear and is of the first pieces that divers need. It is important to choose a diving mask that is comfortable and fits you well, whether you are going freediving or diving with scuba.

This mask creates a pocket of air in front of your eyes and nose so that you can see clearly underwater. It also equalizes the pressure on your ears and sinuses as you go deeper.

Scuba BCDs (Buoyancy Compensators or Buoyancy Control Device)

Scuba BCDs are backpack-like devices that support the weight of your tank above water. They also help you control your position in the water column; this is their most important function.

Add air to your scuba BCD’s internal bladder so that you can rise toward the surface, and vent air from it so that you can sink toward the bottom.

Types of scuba BCDs include jacket-style, back-inflate, and backplate and wing, with all different preferences and diving styles suiting the scuba divers.

Scuba Diving Regulators

A scuba diving regulator enables you to breathe underwater. It connects to the scuba tank and converts the compressed air to breathable air when you inhale.

Also, there is a scuba diving octopus that is a backup regulator with a longer hose and a bright yellow body; some may use it easily and others may use it in an emergency.

Diving Fins

Scuba diving fins make your movement smooth and efficient through a medium that is 800 times denser than air. Fins are worn on bare feet, and the open heel or adjustable fins require you to wear neoprene booties for a proper fit.

There are different types of fins designated for different types of diving, including but not limited to Tec-diving fins that may be shorter and stiffer for a controlled and powerful movement, as well as the freediving fins that are longer and more efficient.

Scuba Diving Wetsuits

Warm water conducts heat away from your body 25 times faster than air. Scuba wetsuits insulate you against this cooling effect. They are made of foam neoprene rubber or spandex-like materials, and, sometimes, of a fleece lining.

Those scuba wetsuits allow a small layer of water inside, enabling your body to warm that water naturally and keep most of it out.

Scuba Diving Dry-Suits

Scuba dry suits keep you dry. They have special seals and zippers that keep the water out, enabling you to wear the appropriate amount of undergarments and stay warm while diving in the cold water inhabitants.

Dive Computers

Dive computers display critical information in real-time, helping you track information such as time, depth, temperature, etc. Air-integrated dive computers allow you to track how much air is remaining in your scuba tank.

Dive Watches

Dive watches may not be considered an essential piece of scuba diving year but, they can be an indispensable tool underwater. It is the only piece you can wear 24/7 and can be an invaluable backup option for keeping track of your dive time underwater.

As long as your dive watch is water-resistant to 200 meters, the watch will be dependable under all normal diving circumstances.

Scuba Diving Weights

Diving weights are used to balance buoyancy underwater and help divers on their descent. They are made from lead and coated with plastic to aid in corrosion.

They can be added to a weight belt worn on top of a wetsuit and adjusted to the waist. They also can be used with integrated-weight BC’s.

Dive Knives

A diving knife can help you get out of tricky situations underwater. It is important to choose a dive knife that is water-resistant with a sharp blade and a secure grip.

Scuba Diving Lights

Dive lights make diving possible many times, from wreck penetration to night diving. They also keep you safe. Dive lights can be a piece of essential safety gear if you plan to dive in caves, at night or penetrate wrecks.

There is also other scuba diving gear that you may choose to have or not, such as diving accessories like GPS rescue devices, underwater slates, or tank bangers. Also, there are underwater cameras and snorkel gear.

Risks of Scuba Diving

Diving entails some risks, such as decompression sickness, arterial embolism, and drowning. Also, diving has effects, such as nitrogen narcosis which can contribute to the cause of these problems.

However, careful and proper training and preparation can make these risks quite rare.

This harm is possible if you don’t practice well, as there are many health benefits of diving, you have to know it.
