Firstly, hold the mirror in your fingers, ensuring your fingers tips are aligned on the mirror's edges. This guarantees that most of the reflected light reaches the target. A glass signal mirror is the traditional choice and is known for its durability and high reflectivity. Glass mirrors are scratch-resistant and can last for many years if properly cared for. However, they are heavier and more fragile than other options, which can be a disadvantage in a survival situation. The manoeuvre part of MSM can be many things from roundabouts, junctions, changing lanes or parking up to mention just a few. The manoeuvre part is often extended into Position, Speed and Look making MSPSL to further aid learner drivers.

If you are stranded in a coastal state and can only have one small item with you, you want a signal mirror. This small tool is versatile, functional, and an important inclusion in emergency and survival kits. A regular mirror is not quite as good as a signal mirror, but we’ll get into that difference below. We’ll also explain what signal mirrors are and how to use them. Next, draw the mirror closer to your face, and while looking through the hole, aim for the aircraft above you by focusing the reflection towards it. That rafter isn't alone in owing his life to a signal mirror. Over the decades, there have been many other people stranded in dire situations in the wilderness or at sea whose lives have been saved by this simple device.Next, ensure the mirror perfectly faces in the direction of the sun to create a reflection. You can use your inactive hand to shield your eyes from the intense sun rays. Signal mirrors are a great survival resource for signaling, but also can be used as a camp mirror, redirecting light for a light source, or for discrete observation. Hodge, A. Trevor (2001). "Reflections on the Shield at Marathon". The Annual of the British School at Athens. 96: 237–259. doi: 10.1017/s0068245400005281. JSTOR 30073279. S2CID 128558448.

In the even that both your target and the sun are not in front of you, you’ll need to angle your body as much as 90 degrees from the sun to direct the light accurately. Immediately prior to the outbreak of World War I, the cavalry regiments of the Russian Imperial Army were still being trained in heliograph communications to augment the efficiency of their scouting and reporting roles. [35] The Red Army during the Russian Civil War made use of a series of heliograph stations to disseminate intelligence efficiently about basmachi rebel movements in Turkestan in 1926. [36] British troops training with a heliograph, Egypt, June 1940 Active Signaling: Distress signals can be broken down into “passive” and “active.” Passive signals don’t require any work once set up, such as an SOS sign. Active signals have to be constantly done, which means you aren’t able to do other survival tasks. Signal mirrors are active. If you’re trapped as a hostage where you’re unable to speak, you can try blinking for help! This clever SOS signal can be done by blinking fast three times, blinking slowly three times, and then blinking fast three times once more. A night in the woods can be scary, but if you have a flashlight, you can use it to signal SOS via Morse code. Flash the light three times rapidly, then slowly for another three times, and then rapidly for three seconds once more. Try to keep the “rapid flashing” to less than a second if you can and the “slow flashing” to just over one second in length.

The first digitally controlled heliograph was designed and built in 2015. [48] [49] It was a semi-finalist in the Broadcom MASTERS competition. [50] See also [ edit ] In 1991, after a plane crashed in the waters of the Caribbean, four survivors in life vests struggled to get the attention of boats and aircraft that passed nearby but did not notice them. When using a signal mirror, you need to have a basic understanding of reflection and light as well. The Best Glide ASE Military Grade Glass Signaling Mirrors are the Mark 3 Emergency Signal Mirrors MIL-M-18731E Type I (2 x 3) and Type II (3 x 5). The Type I (2 x 3) carries the designation NSN: 6350-01-455-6695 and the Type II (3 x 5) carries the designation NSN:6350-01-455-6671. A signal mirror is helpful on a sunny day. However, when both your target and the sun are not in front of you, you will need to position yourself 90 degrees from the sun to be able to direct light accurately.
