Using a Signal Mirror

Although there are commercially-available signal mirrors available, being able to use any flat, highly-reflective surface to signal rescue personnel (either on the ground or in an aircraft) is a vital and essential skill. While many YouTube videos make this method appear easy, what many of them fail to demonstrate is parallax. In this video, I will explain what parallax is, why it's important to understand, and how to compensate for it. To watch the video (referred to here) about impromptu reflective surfaces one might be able to press into service:    • Impromptu Signal Surfaces   Be sure to share, like subscribe and comment.
