Scuba diving is a mode of underwater diving where the diver uses a self-contained underwater breathing apparatus, which is completely independent of surface supply, to breathe underwater.
You must get scuba certified and you need a license to dive and you should not attempt to do so without. It is just like driving a car. … The PADI open water diver course is the first diving certification course you can enroll to become a fully certified diver.
As active recreational pastimes go, scuba diving is one of the easiest to learn. While you’re gliding around enjoying the underwater sights, you’re engaged in only three basic skills: floating, kicking and breathing. The necessary skills are not tough for most people to master.
