GPS is great but what happens when your battery dies, and you don’t have a portable battery handy? The compass is the one piece of survival gear that will never let you down. Sure, it can’t tell you if there’s a town nearby but it can prevent you from wandering aimlessly in circles. The Eyesky compass is designed specifically to help extricate you from emergency situations. It features conversion charts to measure distances, a rotating bezel ring to determine your heading and adjustable sight lines to plot your course. It’s also built to last. It will take you all of an afternoon to learn how to use the Eyesky compass and it may turn out to be the most valuable afternoon you ever spent.
Again, the reason we tend to look sideways at those who get a little too into prepping for an apocalypse is because of their smug optimism. People actually being realistic about a dangerous future would be better served joining the military or ingratiating themselves with high-level government officials than agonizing about a little mouth scuzz or foot fuzz, right?

However, if some tales of survivalist stockpiling are to be believed, our nutty neighbors have enough of the social lubricant squirreled away to hold the most epic end-of-the-world-party of all time outside of Edgar Wright's social circle. It might not be practical, but who needs practical when you and everyone you know is doomed to die from radiation poisoning or cancer?

According to our research, these flexible, durable, waterproof wonders will be as much of a deciding factor in your dystopian longevity as fire and can openers.
I sincerely feel that the best of all of us comes out in a disaster, with exception to a few. These few are the ones that this article does not or should focus on. Avoidance of perspective team members should be steered more by ethics, integrity and morality. I personally avoid thieves, liars and evil-hearted persons, and lastly the drama queens or snakes (team busters). Everyone else is trainable, deserving of a chance and usually becomes a viable team member in a short amount of time. But back to Powderkeg’s comment, “I can’t save the world, only my family.” This is another one that wasn’t mentioned in the article – The Save The World or Everyone Prepper.
Another concern when you’re lost in the wild is where to procure potable water. Sometimes there will be bubbling streams of crystal clear water rolling down wooded hillsides to fill your water bottle and sometimes you’ll have little more than a stagnant pool standing between you and dehydration. The LifeStraw Personal Water Filter is survival gear that can turn that stagnant pool into a lifesaver.
