With a license, you can enjoy diving freely without an instructor. Diving as a sport or profession, such as technical diving, free diving, and commercial diving, is also possible with a license.

Scuba diving is a marine activity that even beginners can experience. However, if you're afraid of suddenly being underwater, you can also start from the beach; this is called a beach dive.
