Survival Tip #6 Find some means of alerting rescuers to your whereabouts. If you are lost in a desert, writing a large SOS in the sand with your water is an effective means of drawing attention. If you are lost in a jungle, a simple two-way radio can be constructed from kits available at any Tandy or RadioShack store. Waving your arms at passing rescue planes expends precious energy, so it is better to dig a small hole, lay in it, cover yourself with leaves to keep warm and relax while you wait for them to find you.
