Questions about navigation and signaling
Why carry a paper map?
Phones lose signal and battery. A paper map of your area and evacuation routes works in any outage.
What is the distress signal with a whistle?
Three blasts, repeated, is the widely recognised signal for help. A whistle carries much farther than a voice.
Do I need a GPS if I have a phone?
A handheld GPS works without cell service and has longer battery life; a phone with offline maps is a good backup.
