Buoyancy Compensator (diving)
A buoyancy compensator also called a buoyancy control device, BC, BCD, stabilizer, stabilisor, stab jacket, wing or ABLJ depending on design, is a piece of diving equipment containing a bladder which is worn by divers to establish neutral buoyancy underwater and positive buoyancy on the surface, when needed. The buoyancy is controlled by adjusting the volume of air in the bladder.

Famous quotes containing the word buoyancy:
“The boatmen appeared to lead an easy and contented life, and we thought that we should prefer their employment ourselves to many professions which are much more sought after. They suggested how few circumstances are necessary to the well-being and serenity of man, how indifferent all employments are, and that any may seem noble and poetic to the eyes of men, if pursued with sufficient buoyancy and freedom.”
—Henry David Thoreau (1817–1862)
