  1. What is the purpose of a 'safety reel' (also called a 'gap reel') carried by cave divers?

    Answer: To bridge a gap between two existing guidelines when a section of line is missing

    A gap reel allows a diver to connect across a section where the permanent guideline is missing or broken, maintaining a continuous exit path.

  2. Which PADI specialty prerequisite is required before enrolling in the PADI Cave Diver course?

    Answer: PADI Cavern Diver and PADI Intro to Cave Diver (or equivalent)

    The PADI Cave Diver course requires completion of both Cavern Diver and Introduction to Cave Diver courses to build skills progressively.

  3. What is 'flow' in the context of cave diving, and why is it important for gas planning?

    Answer: The direction of water current inside a cave which affects gas consumption and penetration distance

    Diving against flow on the way out requires more effort and gas; divers must plan gas reserves accounting for an exit against current.

  4. Inside a wreck, a diver notices lines tied around structural features in multiple directions with no arrows. What should the diver do?

    Answer: Stop penetration, carefully return to the entry point, and exit the wreck

    Confusing or unmarked lines indicate a poorly mapped or multi-team environment; the safest response is to abort and exit.

  5. Which type of buoyancy position is recommended for navigating through tight wreck or cave restrictions?

    Answer: Horizontal trim with hands forward and fins raised

    Horizontal trim minimizes the diver's profile and keeps fins from striking the floor or ceiling, reducing silt disturbance through restrictions.

  6. What does it mean when a cave diver signals by tapping their light on a surface three times?

    Answer: Emergency, something is seriously wrong

    Three taps on any surface with a light or hand is a universal emergency signal in cave and wreck diving meaning immediate attention is required.

  7. What is the minimum recommended team size for a full cave penetration dive beyond the cavern zone?

    Answer: Two divers

    A minimum buddy team of two is required for cave penetration; a third diver adds redundancy but two is the accepted standard minimum.
