Figure 1. Tecline Donut buoyancy compensator series models used
The basic components of this compensator:
• buoyancy bag,
• inflator,
• medium pressure hose,
• pressure relief valve.
A very important element is the buoyancy compensator inflator which consists of an
inflator button, which allows the buoyancy compensator to be filled with air and the
deflator button which allows the buoyancy compensator to be emptied of air
contained in its interior and nozzle which also enables air to be emptied from the
interior of the buoyancy compensator. Thanks to this, it is possible to fill the buoyancy
compensator with your mouth (orally).
.
These elements are shown in the pictures listed below
