Scuba is a type of diving where you use a breathing apparatus to explore the ocean. It’s usually done recreationally as a sport or on vacation. It’s an incredible way to see the wonders of the underwater world.

Scuba diving is an exciting and adventurous activity that requires training to learn how to do safely. Often, beginner’s classes are held at a local dive shop to learn the skills necessary for safe and enjoyable diving. During the course, you will learn to operate your equipment and how to plan and execute simple dives.

While it is possible to be a recreational scuba diver without having a certification, most people choose to obtain their beginner’s scuba certification before they travel for their diving adventures. This certification usually takes three to four days of lessons taught at the dive shop. During this time you will receive some theory training and take an exam, then you’ll complete pool training and open water dives to get your certification.

One of the most serious issues that can affect scuba divers is running out of breathing gas under water. This is referred to as an “out-of-air” emergency and can be fatal in a matter of minutes. The best way to prevent this issue is to always dive with a buddy.

Additionally, it’s important to follow the rules of scuba diving and to never hold your breath underwater. This can cause nitrogen bubbles to form in your bloodstream, which can be fatal. Similarly, it’s dangerous to ascend too quickly.
