Why Signalling Matters
Being seen is often more important than walking out. Rescuers are looking for you—help them find you.
Signal Mirror Technique
- Hold mirror near eye
- Extend other hand, make V with fingers
- Position aircraft/rescuer in V
- Angle mirror until flash hits target
- Sweep across target repeatedly
Range: Up to 50+ miles in clear conditions
