What is Scuba Diving?

Ever wonder what Scuba Diving is?

The term “SCUBA” is an acronym for “Self-Contained Underwater Breathing Apparatus”.


First of all, Scuba is one of a few ways of underwater diving. Scuba divers carry their own source of air, allowing them greater freedom of movement underwater. There are many forms of scuba diving available to explore the underwater world.

A Little History

In addition, by the early twentieth century, two basic types for scuba diving had emerged:

Open-circuit diving where the diver’s exhaust is vented directly into the water.

Closed-circuit scuba diving where the diver’s unused oxygen is filtered from the carbon dioxide and recirculated underwater.

In 1943, Emile Gagnan and Jacques-Yves Cousteau developed a crude prototype for the ‘Aqua-Lung’. The Aqualung was a scuba unit where cylinders filled with compressed air carried on the back could be inhaled through a demand regulator and then exhaled into the water. This was the first commercially successful scuba diving regulator for recreational divers.

Over the years, Cousteau continued to modify and improve the breathing device to allow him to remain underwater for longer periods of time. The Aqua-Lung evolved into the modern scuba equipment of today and has become the standard used worldwide. Also, it is recognized as one of the most important inventions of the 20th Century.

Evolution of Scuba Diving

In conclusion, scuba diving has come a long way since it’s beginnings. It is no longer an activity just for military or specialized groups. Dive training agencies formed in the beginning of the 20th century to prepare aware and responsible scuba divers through education. The educational materials available today are cutting edge, dynamic and interactive, from Recreational Diving to Technical Decompression Diving, making this amazing sport available to almost everyone.

As recreational diving and technical diving are recognized as carrying a degree of risk and responsibility not normally associated with other recreational sports, scuba diving is a highly regulated industry with standards and procedures.

Besides that, diving instructors of all associations must follow highly meticulously crafted courses with regards to theories and techniques involved in teaching scuba diving courses as a whole.

As well, scuba equipment has come a long way. Science and technology has allowed for safer equipment and comfort. It is now available in different sizes and colors with amazing safety features. This is excellent because it allows everyone from 10 years and up to scuba dive!

Becoming a scuba diver is a wonderful Underwater World Adventure!

Scuba Diving Courses include three phases:

1. Knowledge Development

Whether you are taking a PADI or SDI course, for the first phase of your scuba lessons, you’ll learn the basic principles of scuba diving, scuba equipment, decompression sickness and the use of scuba gear

During the diving course you’ll learn this valuable information by reading your diver manual, studying the scuba divers course online and/or watching the training video (depending on your particular course). Besides, you’ll answer questions about the material to ensure your understanding of it. Along the way, let your dive Instructor know if there is anything you don’t understand. At the end of the course, (except for some Specialty courses) you will take a final exam that ensures you have thorough knowledge of the materials covered.

2. Confined Water Dives

Also, you need time to practice. If you are starting diving you will develop basic scuba diving abilities in the pool or confined water; a body of water with pool-like conditions, such as an open water Cenote. The basic skills you learn during your course will help you become familiar with your scuba equipment. These are some of the essential things you will learn:

  • How to set up your scuba equipment
  • Buoyancy control
  • Safety procedures
  • Using Scuba
  • Nitrogen issues
You’ll practice these with your instructor until you’re comfortable. When you’re ready, you’ll move into the exploration of the underwater world in an open water dive site.
Besides, if you are taking a specialty course like Sidemount Diver Course or Peak Performance Buoyancy, we will work on your current level, curbing any ‘bad habits’ and introduce new exercises for that particular diving program.

3. Open Water Dives

After your confined water scuba dive, we will head to “open water”. Besides witnessing the amazements of Mother Nature underwater, you will apply what you learned in confined water.
Learning to dive is performance based.

“From birth, man carries the weight of gravity on his shoulders, He is bolted to earth. But man has only to sink beneath the surface and he is free.”

Jacques-Yves Cousteau

Inventor of the Aqua Lung
