What is the standard response to a 2-1 line pull from the diver to the tender?

• A. I understand or Talk to me.
• B. I am all right.
• C. Stand by to come up.
• D. Ventilate

Answer: (A)

Two pulls on the line from the diver to the tender signal a request to communicate. The best response is to acknowledge and invite dialogue, such as saying “I understand” or “Talk to me.” This keeps the communication channel open and lets the diver explain the issue, supply status, or questions, which is essential in restricted or noisy environments where verbal contact may be limited or unreliable.

If the diver isn’t seeking immediate dialogue, other signals like “I am all right” would prematurely close the line of communication, while “Stand by to come up” is an action instruction not suited to initiating conversation. “Ventilate” isn’t a relevant or standard response in this signaling context.
