Repairs and First Aid
In a survival situation it is important that your gear is in working order. Carry a sewing kit for tears, a patch kit for tents, and seam sealer. For first aid, carry bandages, gauze, athletic tape, aspirin, hydrogen peroxide, triple antibiotic ointment and extra medicine for any pre-existing conditions.
In a survival situation you will need water, food and shelter. If it is cold you will need to start a fire. Bring magnesium fire starters, waterproof matches, a tarp or poncho for shelter, nylon rope to construct the shelter, knife or hatchet for firewood, high calorie content food, iodine tablets for water purification and a water container. If you are hiking near water, bring fishing line and hooks.
There are several tools built specifically for signalling help. A whistle is a valuable tool for making noise. It will alert predators of your presence and signal people for help. A mirror is a good tool for signaling a search helicopter. The most valuable tool may be a satellite communication device. A phone makes it easy to call for help while a SPOT communicator makes it possible to send for help or make a direct call to emergency services with your GPS coordinates.
