User:Saturday101/Scuba skills

Some skills are generally accepted by recreational diver certification agencies as necessary for any scuba diver to be considered competent to dive without direct supervision. Others are more advanced, although some diver certification and accreditation organizations may consider some of these to also be essential for minimum acceptable entry-level competence. Divers are instructed and assessed on these skills during basic and advanced training, and are expected to remain competent at their level of certification, either by practice or refresher courses. Many organizations recommend one of these options if a diver has a laps of six to twelve months without a dive to be qualified to more advanced activities or trainings.
