A signal mirror flashes sunlight toward aircraft, boats and search teams so they can find you from miles away. It is for the moment you are stranded on a rooftop in a flood or off the road on foot, with no cell signal and no batteries to spare.
A signal mirror turns sunlight into a flash that rescuers can see from miles away, with no batteries and nothing to wear out. Choose one you can aim on the first try.
- Sighting hole: Pick a mirror with a sighting hole and aiming grid so you can put the flash on a plane, boat or search team.
- Size: A 2 by 3 inch mirror rides in a pocket, while a 3 by 5 inch face throws a stronger flash, so stock one per adult bag.
- Material: Choose shatterproof acrylic or polycarbonate for light weight, or tempered glass for the brightest reflection.
- Lanyard: Look for a lanyard hole so you can tie the mirror to your wrist and keep it out of floodwater.
- Storage: Keep it in its sleeve so scratches never dull the face and weaken the flash.
