BC in the context of scuba diving stands for Buoyancy Compensator.
Understanding the Buoyancy Compensator (BC)
A buoyancy compensator (BC), as described in our reference, is a vital piece of diving equipment. It helps divers achieve and maintain neutral buoyancy underwater and positive buoyancy on the surface. It's also referred to by various names:
- Buoyancy Control Device (BCD)
- Stabilizer
- Stabilisor
- Stab Jacket
- Wing
- Adjustable Buoyancy Life Jacket (ABLJ)
Function of a BC
The primary function of a BC is buoyancy control. Here's how it works:
- Neutral Buoyancy Underwater: Divers add or release air into the BC to offset the effects of depth and equipment weight, achieving a state of neutral buoyancy where they neither sink nor float.
- Positive Buoyancy at the Surface: By fully inflating the BC, divers can float comfortably on the surface, conserving energy and signaling for assistance if needed.
