Survival gear is pretty much anything that can be used in an emergency situation, and can often mean the difference between life and death. It includes everything from hunting and fishing gear to food, water, shelter and fire. Survival gear tends to be for sustaining yourself in the wild, but not exclusively - there are situations at home that mean that survival gear is a necessary requirement, for example natural disasters or terrorist attacks. If you decide to put together your own survival gear, bear in mind the situations it may be used for and build it up accordingly, though it is possible to buy kits already stocked with everything you may need. Typically, survival gear is focused on those who spend time miles away from civilization. Outdoor enthusiasts accept that there may be times when they get lost or suffer serious injury, and so they need to be prepared before they set off on their adventures. There are many items available, so again, even if you buy a ready prepared pack, consideration must be given to where it might be needed - there is little point taking one that is designed for a winter emergency if you are heading for the desert.
Some of the items available are heating and cooling products, mosquito nets and water purification tablets: the best way of purifying water is to boil it though this is not always possible. There are fishing kits that can fold so they can easily fit into a pocket, or be packed away with the rest of your survival gear; fire flints and utility knives. Water canteens are also common, but consider the weight of water before you fill them to take with you. If you are in an emergency situation, you will probably have to find water for yourself and purify it - but having a water canteen means that you, at least, have a means of containing it. Survival gear that comes in kit form usually includes food items too and are most commonly snack bars or Meals Ready to Eat, also known as MREs.
These are military issue meals such as stew, pasta or even grilled chicken and beef patties. The kits can also come with signaling and navigation tools, such as a compass and GPS - be careful about relying on GPS, though, as signal strength can be very hit and miss out in the middle of nowhere, and your battery may die, too. Whistles and mirrors make good signaling tools - your voice will get hoarse very quickly if you are shouting for help but you can blast away on a whistle for a lot longer. Flares and strobe lights are other options for including in survival gear. First aid kits and medical supplies should be considered carefully, taking into account what you are actually capable of dealing with - some serious injuries can only be dealt with by professionals, and what you are likely you come across. The most basic kit will contain the usual bandages, antiseptic and basic medications, such as painkillers and anti-inflammatories. It is certainly worthwhile considering blood clotting compresses, which will prevent severe blood loss, and an extractor pump for snake bites. If you are prepared, and have a good survival gear kit, you will have a very good chance should the worst happen. No matter that we all hope it will never need to be opened, they are a vital piece of equipment that could actually save your life.
