Recreational diver training is the process of developing skills and knowledge in the use of diving equipment and techniques so that the diver is able to dive with minimum risks. Not only is the underwater environment hazardous but diving equipment can be dangerous, there are unexpected problems that divers must learn to avoid.
Divers need practice and a gradual increase in challenge to build their confidence in their equipment and themselves, to develop the skills needed to control the equipment and to respond properly if they encounter difficulties. Most commercial operators and dive clubs serving divers insist that each diver is able to show them “certification”, for the type of diving the diver intends to do.
