The signal mirror is an easy and effective way to send an SOS signal or indicate your position. Use sunlight, moonlight or flashlights to transmit signals.
The signal mirror has a special hole in the middle, which acts like a collimator. This allows you to aim the reflected light at greater distances. In an emergency, it is possible to call for help with an SOS signal, e.g. by aiming at a ship or aircraft.
The mirror comes with instructions on the back and a button compass.
