If signaling options fail and electronic devices are unusable, which signaling set is recommended?

• A. GPS device, satellite phone, beacon
• B. Whistle, mirror, flares
• C. PFD, spare paddle, map
• D. Flares, mirror, whistle

Answer: (D)

Non-electronic distress signaling relies on audible, visual, and reflective cues to catch attention. Flares provide a clear visual distress signal that can be seen from a distance day or night; a mirror lets you flash sunlight toward a boat or aircraft to draw attention; a whistle emits a loud, attention-grabbing sound that can be heard over water and through wind. If signaling options fail and electronics are unusable, these three items give you multiple ways to be detected by nearby vessels or rescuers, increasing your chances of being found without relying on batteries or signal networks. The other options rely on electronic devices or do not provide effective signaling on their own: a GPS device, satellite phone, and beacon require power and networks; a PFD, spare paddle, and map are for staying afloat and navigation, not for signaling rescuers. Therefore, the set of flares, mirror, and whistle is the best all-around non-electronic signaling kit.
