SDI Dry Suit Diver Practice Test

The basic components of a dry suit include the main body, seals (such as wrist and neck seals), valves, and boots. The main body is the suit's primary structure, designed to provide insulation and keep water away from the diver's body. The seals are critical because they prevent water from entering the suit, ensuring it maintains a dry environment inside. The valves, typically an inflator valve and a dump valve, allow divers to manage buoyancy by adding or releasing air from the suit. Finally, the boots are integrated into the suit or worn separately, providing thermal protection for the feet and aiding in comfort and mobility. Together, these components make the dry suit effective for diving in cold water environments by keeping the diver dry and warm.

Other options include components that do not form fundamental parts of a dry suit structure or function. For example, adjustable straps and weights are not inherent features of a dry suit; they may be used in diving gear but are not essential parts of the dry suit itself.
