During Special Signals From the Diver, what is the meaning of 1-2-3 line pulls?

• A. Stop and search where you are.
• B. Send me a square mark.
• C. Face your umbilical, take a strain, move right.
• D. Less air.

Answer: (B)

In diver-to-surface signaling, a lifeline is used with coded line-pull sequences to request specific actions from the surface team. The three-tug pattern is a recognized code for asking the surface to send down a square marker. When the diver performs that 1-2-3 pull, the surface crew understands it as a directive to deliver and place a square mark along the line, which helps visually indicate location or status along the dive.

This is the best answer because that particular pull sequence is explicitly tied to requesting the square marker, and it’s a standard, unambiguous signal in special signaling. The other options describe different actions or signals that would be conveyed by other patterns or gestures, not by this three-pull code.
