sukellusliiviä

Sukellusliivi, also known as a buoyancy compensator (BC) or buoyancy control device (BCD), is a critical piece of equipment for scuba divers. Its primary function is to allow divers to control their buoyancy underwater. By adjusting the amount of air inside the vest, divers can achieve neutral buoyancy, meaning they neither sink nor float. This control is essential for safe and comfortable diving, enabling divers to hover at specific depths, ascend or descend slowly, and maintain a stable position.

Sukellusliivi typically consists of an inflatable bladder, a harness, and a low-pressure inflator hose connected to the scuba tank's regulator. The diver can inflate the bladder using air from the tank via the inflator mechanism or by mouth. Conversely, air can be released from the bladder through dump valves to descend. Many sukellusliivi also feature integrated weights, eliminating the need for a separate weight belt, and pockets for accessories. Different styles of sukellusliivi exist, including jacket-style, back-inflate, and wing-style, each offering distinct advantages in terms of comfort, stability, and trim. Proper maintenance and understanding of its operation are vital for every diver.
