In a 2-2-2 emergency signal, what is the meaning?

• A. I am fouled but can clear myself.
• B. Stop and search where you are.
• C. I am fouled and need the assistance of another diver.
• D. Haul me up immediately.

Answer: (C)

The main idea here is recognizing a standardized distress signal used underwater. The 2-2-2 pattern is the cue that you are fouled or entangled and you need help from another diver. It’s chosen because it clearly communicates “I can’t free myself; I need buddy assistance” in a loud, simple, repeatable way that works with a mask and regulator. This tells your buddy to intervene—untangle you, assist with freeing you, or aid in an ascent if necessary. If you can free yourself without help, you’d use a different signal, since the 2-2-2 pattern indicates you need external assistance.
