What is the signaling mirror best used for?

• A. Loud signal for vessels
• B. Attract attention with sunlight reflection
• C. Visual distress signal, day/night use
• D. Survival blanket use

Answer: (B)

The signaling mirror is most effective because it uses sunlight to create a bright flash that catches the attention of others at a distance. By angling the reflective surface toward the sun and toward a potential observer, you generate a quick, noticeable signal that can be seen from far away, making it a reliable daytime visual signal for rescue or attracting passing vessels. It isn’t primarily an audible signal like a whistle, it isn’t a survival blanket, and while it can be part of visual distress signaling, its strongest use is the sunlight reflection bright flash during daylight. At night or in poor light, other signaling methods are needed.
