survival tip

Always have two signal mirrors.

Relying on one signal mirror isn’t a good idea because the sun always travels south. This means that a single mirror will not allow you to catch the attention of rescuers flying from the north. The second signal mirror will be essential to reflect the light you get from the south to reflect it into the northern direction. Simply hold one of the mirrors facing south and another facing north, making sure that the light bounces off both.
