Scuba skills are the skills required to dive safely using self-contained underwater breathing apparatus, (scuba). Most of these skills are relevant to both open circuit and rebreather scuba, and many are also relevant to surface-supplied diving. Some of the skills are generally accepted by recreational diver certification agencies〔 as necessary for any scuba diver to be considered competent to dive without direct supervision, and others are more advanced, though some diver certification and accreditation organizations〔 may consider some of these to also be essential for minimum acceptable entry level competence. ==Basic open circuit scuba equipment skills==
