Frequently Asked Questions

How do I use a daylight signal mirror?

To send a distress signal, position the mirror so that sunlight reflects through the sighting hole and aim the reflected beam at the target vessel or aircraft. Slight adjustments will create a flashing effect that attracts attention.

Can a daylight signal mirror be used in overcast conditions?

Yes, even on hazy or partially cloudy days, the mirror can reflect available sunlight. It works best with direct bright sunlight, but overcast conditions may still allow intermittent flashes if gaps in the clouds expose the sun.

Is the daylight signal mirror required on commercial ships?

Signal mirrors are recognized as important visual distress signaling devices and are often included in vessel safety equipment. While specific carriage requirements depend on vessel type and operating area, having a redundant signaling device is a good safety practice.

How should I maintain the signal mirror?

Rinse with fresh water after saltwater exposure and dry with a soft cloth. Avoid scratching the mirror surface. Store in the provided protective pouch and keep it in an easily accessible location.
