The compass will get you moving in the right direction but when night descends you’ll need a strong dependable light source and the J5 Tactical flashlight is that and more. The J5 produces an incredibly intense beam from a single AA battery. It’s essential survival gear that can be seen from miles away so even if you can’t see anyone else there’s a good chance someone else will see you.
To me, the best option is to store emergency food. How much? If you have none, store enough for a few days. If you have enough for a few days, get enough for a week. How much you store depends on what time frame you think you're at risk for having to be completely independent. The early settlers of the southwest liked to store enough food for a whole year and still do to this day!
