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

• A. Send me a slate.
• B. Send me a line.
• C. Face your umbilical, take a strain, move left.
• D. Stop and search where you are.

Answer: (A)

The main idea here is how divers use a coded line-pull sequence to communicate when talking isn’t possible underwater. A specific pattern of two pulls, then one, then two pulls is the code for asking to be given a slate. A slate lets the diver write a precise message that would be hard to convey with gestures alone—things like recording depth, time, or other details, or requesting a written communication from surface. The surface team recognizes this sequence and provides a slate so the diver can write back. The other options don’t fit because they refer to different actions or messages that have their own signals or aren’t conveyed by this 2-1-2 pattern.
