Whilst doing a search for surface signaling devices I came across this report.
For all the people that think a CD makes a good signaling mirror you may change your mind after reading this. In the commercial mirrors the hole in the middle is not for pointing at the target but to look through until you see a orange ball then place the ball on the target.
