Quick Answer
Effective signaling devices increase your chances of rescue by producing a high visibility signal that can be spotted from a distance, such as flares, mirrors, and smoke signals. These devices should be used during the day and night to maximize visibility. A combination of devices can increase your chances of being seen.
Visible Signaling Devices
When it comes to signaling for help, visible devices are essential. Flares are a good option, but they only last for a few minutes. You can use a flare to get attention, then switch to a more long-term signaling device, such as a mirror. A mirror can reflect the sun’s light towards any aircraft or rescuers during the day. It’s essential to use a mirror with a 2-inch or larger reflective surface to ensure maximum visibility. You can also use a piece of glass or a shiny surface to create a makeshift mirror.
Noise-Making Signaling Devices
In addition to visible devices, noise-making devices can be just as effective. Whistle signaling is a classic technique, and it’s easy to do. A pea-less whistle is the best option, as it can produce a loud, high-pitched sound that can be heard from a distance. The recommended whistle is the Fox 40 Whistle, which can produce a sound of up to 120 decibels. This is loud enough to be heard from a distance, but not so loud that it causes hearing damage.
Shelter and Signaling
When creating a shelter, it’s essential to make it visible from the air. Use bright colors, such as orange or yellow, to make your shelter stand out. You can also use a brightly colored tarp or plastic sheet to create a makeshift signal. Attach the signal to a long piece of rope or a tree branch, and hang it high enough to be seen from a distance. This will make it easier for rescuers to spot your shelter and location.
