You should look at a free market, where people sell used things, for equipment that you need. Often you get a knife, a simple steel spoon, a military pot, a rucksack or a summer sleeping bag very cheap at markets like that, especially, if you tell the people, that you do not have so much money and want to go with your friend for a bit camping in your local forest. The people, who sell that old things will normally give it you very cheap, especially if you are young.
Personal Locator Beacons: These are smaller, affordable, reliable, and offer many new features. Companies like SPOT and DeLorme now offer products that post almost real-time tracks of adventurers far off the grid. The SPOT Gen3, for example, sells for as low as $150 and enables users to send simple, pre-programmed messages (all ok, send help, etc.) to friends and family or initiate rescue through a first-responder network.
The art direction helps push the idea of hope home, with bright and shiny technologies, beautifully blue oceans, and schools of tropical fish filling your vision at every turn. You explore the ocean depths in your submarine, searching for new materials in marine trenches and among coral reefs. And when you’ve found everything you need, you can begin to construct bases on the ocean floor.
Like any emergency kit, the Pocket Survival Pak — which was developed by Doug Ritter, founder of the survivalist website Equipped To Survive — can help lost or injured explorers signal helicopters and planes, start fires, boil water, melt snow for water, catch fish, navigate through the woods, trap small animals, perform rudimentary first aid, and repair damaged gear.
When water is murky you need to pre-filter the water to remove suspended matter. A Millbank bag or one of the newer Brown Filter Bags is a really good way of doing this. These bags provide a low-cost, low-tech (read hard-to-break), reliable method of coarse filtration, something that is necessary in all but crystal clear waters. To remove any turbidity from the water is important because suspended particles in water can irritate your gut even if there are no pathogenic organisms present. This means pre-filtering with a filter bag followed by boiling is an excellent methodology.
You’ll obviously need to tailor your survival kit to the number of people who will depend upon it. If you are going out for a solo camping trip, you won’t need as many supplies as if you are heading out with an 8-person team. The number of people depending on the kit won’t affect some of the items in the kit, but it will affect others. For example, you’ll only need one fire starter, no matter how many people are in your party. By contrast, you’ll obviously need to adjust how many space blankets are included with the kit, depending on the size of the group. My $100 Walmart Survival Kit - 7 Day Survival Challenge - The Build
