First things first, can you dive if you are not certified?
Yes, but your options are restricted, and you must first complete some basic training and be a beginner diver at least. To see if diving is for you, attend an introductory Discover Scuba Diving (DSD) training course. Beginners are often taught how to scuba dive in an enclosed space, such as a swimming pool or confined places in open waters.
If your discovery dive goes well and you want to dive deeper in open waters, the next step is to become certified, find everything you need to know about getting your scuba diving certification here »
The Professional Association of Diving Instructors (PADI) is the world’s largest scuba diving certification organization, although it is not the only one.
It is recommended to start with the big agencies when seeking for information to help you select which training agency is ideal for you. PADI, NAUI, SSI, BSAC, and SDI are among the certifications available.
The correct scuba diving certification programme is critical to your safety and enjoyment of the sport. There are numerous points to consider while selecting one. Often people learn to scuba dive at a center that is close to where they live. However, other things to keep in mind are: What type of diving (recreational, technical, rebreather, etc.) do you wish to get certified in? What is the duration of the course and how much does it cost per day/weekend session? What are your time constraints, such as job or school schedules?
