In addition to using it for emergency signaling, it’s handy for personal grooming as well. The virtually unbreakable Floating Mirror also features a lanyard hole for convenient attachment to gear, and it works even in overcast conditions or at night with moonlight or other light sources. Instructions 1 – Stand facing the sun or other light source in an open area with a clear view of the sky and, if possible, the horizon. 2 – Reflect light from the light source onto your hand or other nearby surface making sure to not block the light from the light source to the mirror surface. 3 – Slowly bring the mirror toward your eye until the mirror touches your cheek. Look through the star at the reflected light on your hand (or other surface). A bright glowing spot will show in the star. This is the aim indicator. 4 – Holding the mirror close to your eye, and still looking at the aim indicator, slowly turn and angle the mirror until you “place” the aim indicator directly on the object you wish to flash. If no target is in sight, continually sweep the horizon.
