What does a two-line signal from the diver to the tender instruct the diver to do?

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

Answer: (B)

In surface-supplied diving, divers communicate depth changes to the tender with line signals. A two-line signal from the diver to the tender is specifically used to request descent: pay out more line so the diver can lower deeper into the work area. This is about changing depth, not about saying you’re okay, taking up slack, or being hauled up. The action the tender takes in response is to let out line gradually, controlling the rate of descent.
