A buoyancy compensator (BC), also called a buoyancy control device (BCD), stabilizer, stabilisor, stab jacket, wing or adjustable buoyancy life jacket (ABLJ), depending on design, is a type of diving equipment which is worn by divers to establish neutral buoyancy underwater and positive buoyancy at the surface, when needed.
If a weight harness is worn, or the BCD uses an integrated-weights system, the system is checked for correct assembly and function of clip release. A secondary check is to ensure that the buddy is familiar with the weight system of the diver being checked, and is able to operate it to ditch weights in an emergency. R - Releases
This is a glossary of technical terms, jargon, diver slang and acronyms used in underwater diving.The definitions listed are in the context of underwater diving.
The government of Spain issued a royal decree taking effect on 1 July 2020 (Real Decreto 550/2020 de 2 de junio: Condiciones de Seguridad de las actividades de buceo), regulating recreational diving activities [16] [17] [18] Restrictions include: a diver must have the appropriate and necessary training for the type of diving intended,
A backplate and wing (often abbreviated as BP&W or BP/W) is a type of scuba harness with an attached buoyancy compensation device (BCD) which can be used to establish neutral buoyancy underwater and positive buoyancy at the surface. Unlike most other BCDs, the backplate and wing is a modular system, in that it consists of separable components.
Weight belts are the most common weighting system currently in use for recreational diving. [17] Weight belts are often made of tough nylon webbing, but other materials such as rubber can be used. Weight belts for scuba and breathhold diving are generally fitted with a quick release buckle to allow the dumping of weight rapidly in an emergency. [7]

A diving regulator or underwater diving regulator is a pressure regulator that controls the pressure of breathing gas for underwater diving.The most commonly recognised application is to reduce pressurized breathing gas to ambient pressure and deliver it to the diver, but there are also other types of gas pressure regulator used for diving applications.
