Quick Answer
Carry at least one signal mirror in your survival kit, and consider including a backup or an alternative option, such as a shiny surface or a whistle.
Choosing the Right Signal Mirror
When selecting a signal mirror, look for one with a reflective surface that is at least 1 inch by 2 inches in size, and has a parabolic curve that can concentrate sunlight onto a small area. This type of mirror is designed to maximize the intensity of the reflected light, making it more visible from a distance. A popular option is the 2-inch by 3-inch compact signal mirror made of aluminum or silver-coated plastic.
Signal Mirror Techniques
To use a signal mirror effectively, hold it at an angle of 45 degrees to the sun, and adjust your position to reflect the sun’s rays towards any potential rescuers. It’s essential to keep the mirror steady and avoid movement, as this can reduce the effectiveness of the signal. If you’re in a survival situation, use the mirror during the brightest part of the day, typically between 10 am and 4 pm, when the sun is high in the sky.
Additional Signal Options
While a signal mirror is an excellent tool for signaling, it’s also a good idea to include other options in your survival kit, such as a whistle or a brightly colored cloth. A whistle can be used to produce a loud, high-pitched sound that can be heard over long distances, while a brightly colored cloth or bandana can be used to create a visible signal fire or a flag. These alternatives can be used in conjunction with a signal mirror to increase your chances of being seen or heard.
