What is the appropriate reply to a 2-1 line pull from the tender to the diver?

• A. I am all right.
• B. Ventilate
• C. Lower or Give me slack
• D. I understand or Talk to me.

Answer: (D)

A line pull from the tender is a cue to establish two-way communication with the diver. The best reply is to acknowledge the signal and invite further instruction, such as “I understand” or “Talk to me.” This confirms you’ve received the request and are ready to communicate, which is essential for receiving directions, status checks, or task instructions from the surface. Other responses don’t fit because they either reveal your status without addressing the communication cue (I am all right), attempt an action not asked for (ventilate, lower or give me slack), or don’t open the line for dialogue.
