The tube is usually used like a flexible straw. Suppose you were in the desert and saw a line of green and went toward it. You find a mostly dry stream, just mud and a few small pools of water caught in rock basins. You would put one end of your "straw" in the water & the other in your mouth, and suck up the water. You might be able to dig a hole in the mud, line it with a bandana or other clothing, and suck up the water as it accumulates. Mind you, this is not a SAFE thing to do, but it is an alternative to dying of dehydration.

It takes some time, but you could go back through the posts here and get a lot of info. If you find something that you don't understand, you can do a search of this site for it, or just ask.

Having a compass doesn't usually do much for you unless you know how to use it.

Keep in mind that you could conceivably need
*First Aid supplies
*Shelter or knowledge to make it
*Fire starting materials
*Water or a way to get it
*Ways to signal for help
*Food would make you more comfortable, but it's far from being at the top of this list.

Just realize that your most important survival tool is between your ears. If you can't use your head, there's a good chance that you probably won't survive without outside help. A lot of people who have survived have been blessed with pure dumb luck, which always helps, but you can't depend on it.
