SPECIFICATIONS:Mirror Material: 100% Lexan polycarbonateMirrored Surface: Vacuum deposition metalizationTargeting Star: Retroreflective encapsulated beadfabric SIZES:3" x 5" (7.6 x 12.7 cm); Weight: 2.0 oz (62.2g)Three men stranded on a frozen pinnacle of ice were rescued after a passing ship noticed a flash on the distant horizon - a flash from a signal mirror hanging from an unconscious man's neck. From this true story comes the wisdom, "Never underestimate the value of a signaling device." The StarFlash? Signal Mirror is the most valuable daytime means of visual signaling. Even on overcast days, this signal mirror can be used effectively to obtain rescue. You can't be rescued if you can't be found. Ultimate Survival's StarFlash? signal mirror can help you be found, and can save your life. Every military survival kit is required to include a signal mirror and all personnel are trained to use one. Unfortunately, the majority of the general public possesses only limited understanding of the value of a signal mirror and its ability to save their life. The StarFlash? Signal Mirror is one of the most versatile pieces of outdoor equipment you can add to your personal gear. Whether attracting the attention of another hunter several ridge lines away or applying makeup, this mirror offers superior performance. Survival experts worldwide agree that no person should ever venture into the woods, travel off-road, get on board their boat or plane, or engage in any other outdoor activity without a signal mirror and a whistle. Why choose the StarFlash? targetable signal mirror, when other, less expensive mirrors are available? The U.S. Air Force asked that very question before deciding to include StarFlash? in all of their kits. Our mirror is far lighter than glass and is virtually indestructible. It floats, which allows you to recover the mirror if you accidentally drop it overboard. Perhaps most important, however, is the trademarked StarFlash? technology that enables you to aim the flash as far as the eye can see with pinpoint accuracy. Best results with the StarFlash? signal mirror are achieved when the air is clear and the sun is well above the horizon. However, visible signal flashes can be created even on hazy or overcast days. Signal flashes can and may be seen even when you cannot see the aircraft, boat, or other means of rescue. So when signaling and no specific targets are in sight, be sure to continually sweep the horizon to maximize your chances of being seen. At night, flashlights, headlights, and moonlight can produce effective signals with your StarFlash?. While StarFlash? is a state-of-the-art mirror, it also is a practical, multipurpose outdoor tool. Use it around camp for shaving, to apply makeup or camouflage, or for inserting contact lenses. Use it as a silent communications tool to signal an outdoor companion, or for looking around corners or into tight spaces. Use it for emergency signaling to send a pinpoint flash to a rescue plane, helicopter, vehicle, or distant search party.
