Brunette Girl Posing To The Mirror In The Bedroom At Home

Mirrors can also be used for rescue, especially to attract the attention of search and rescue helicopters. Specialised signalling mirrors are available and are often included in military survival kits. Remember that pointing an ordinary mirror directly at the intended receiver will not work if the sun is too far off to the side. The mirror should be pointed directly between the light source and the signal target.
If there are two people, one person can hold their arm so that it points at the target. The signaler, holding the mirror as close to their eyes as possible, so as not to confuse their perspective with that of the mirror, can then see the light moving straight along the arm and directly at the target. Or if this isn't possible, improvise. A clear head in emergencies is the most essential of safety devices.
