Signaling and communication are very important survival things we need to understand. Whistling is a great way to be heard from a far distance. The great thing about a whistle is that it does not make you lose your voice and can be heard much easier than a yell. A glow stick is another thing you will want to have.
- A whistle is far louder than your voice, even at full “eldest child just ran the car into the side of the garage” volume.
- Next on the list is a signal mirror. To use, you hold the mirror out and angle it in such a way that it catches the sun’s rays.
- At night, you can use a glow stick (also known as cyalume snap sticks) and some cordage to reach out for help.
“I recommend a minimum of two whistles.”
