Using a Signal Mirror When Lost: Skill 13
How to Use a Signal Mirror When You're Lost
Signal mirrors can save your life—but they’re harder to use than they look.
The real challenge: aiming the reflection.
Method 1: Dedicated Signal Mirror
If you have a purpose-built mirror with a sighting hole or hologram, use it:
Hold the mirror close to your eye
Aim it at the sun
Look for the bright spot or hologram flash inside the hole
Move the spot onto your target (plane or rescuer)
These mirrors are designed for accuracy and long-range visibility.
Method 2: Improvised Mirror
Using a shiny object (knife, metal lid, phone screen):
Hold it near your right eye with your right hand
Extend your left hand straight out
Make a “V” with your fingers like a finger gun
Shine the light onto the back of your left hand
Put your target inside the “V”
Flick the light up and down to flash your target
This method lets you aim without fancy tools.
Practice Before You Need It
Test this with a friend and a cell phone or radio at a distance.
Train in clear weather and get used to spotting and aiming the flash.
Bottom Line
Signal mirrors are simple but not intuitive.
With a little practice, they become a powerful way to be seen—even miles away.
