What does a three-line pull from the diver to the tender signal the diver should take?

• A. I am all right.
• B. Lower
• C. Take up my slack
• D. Haul me up

Answer: (C)

Three quick pulls on the line are a dedicated way for the diver to tell the tender to take up the slack. The line is the primary connection between diver and surface, and slack in that line can hide signals or delay the tender’s response. By signaling three times, the diver is asking the tender to pull the line in so it becomes taut and the connection is secure. This makes communication reliable and keeps depth and position under better control, especially if currents shift or the diver needs a prompt, predictable response from the surface team.

The other options describe the diver’s status or a different action (being fine, needing more line to be lowered, or being hauled up), rather than adjusting line tension. The triple signal is specifically about tightening the line to remove slack.
