This is why you carry the basics on your person that way if you should get separated from your back pack you can still make fire with a lighter or mag bar or whatever your choice of fire starter is, shelter I carry one of those emergency ponchos and a heatsheet two person blanket, and a good knife. Heck maybe even carry a couple of small tealight candles that way when you cover up with the heatsheet you could place the candle in there to create some extra heat. A beacon is only to notify people that your in trouble you still gotta last until they get to you.
