Radio transceiver, standard VHF marine when operating near inland shore, 121.5 MHz AM VHF guard channel capable aircraft band transceiver to contact rescuers and high overflying commercial and military aircraft visible by contrails, an optional amateur radio if a licensed radio amateur, (see Ham Radio) or an AM/FM/Weather/Shortwave radio receiver to receive precise time for celestial navigation as well as weather information
The problem with most of you prepper types is that you are way too early and wasting your energy. Yes of course I know what you’re all thinking is that we all must be prepared always and yes that is after all the whole point. But all things considered, past present and future .. technology is the real enemy and it has not yet fully evolved. Keep this date in mind and any years that are multiples of 9, (9-18-2027), have enough fuel to make it to the dessert, remove the battery and SIM cards from devices, bring dried food and chlorinated water water and dig in deep, good luck.
Followers of James Wesley Rawles often prepare for multiple scenarios with fortified and well-equipped rural survival retreats. This group anticipates a near-term crisis and seek to be well-armed as well as ready to dispense charity in the event of a disaster. Most take a "deep larder" approach and store food to last years, and a central tenet is geographic seclusion in the northern US intermountain region. They emphasize practical self-sufficiency and homesteading skills.
I am guessing, I am the homesteader. Or, I would call it “shelter in place prepper”. Since, I am in advanced age, I don’t have the mobility of a 20 year old, to bug out. The problem, I see with a homesteader, is if you don’t have the arms and man power to defend what you, then it will all be taken away. Reason, I am into hiding food in plain site. Pecan trees, oak trees, black berry patch, mushrooms, and such.
The stories of alcoholic beverages historically being safer to drink than unfermented ones are apocryphal at best; however, as any 17th-century sailor would tell you, the addition of some spirits to potable water that's been sitting around for too long will make it much more palatable. Liquor distillation was originally invented in part for medical purposes, and alcohol can be used as a solvent to dissolve medicinal herbs -- and also to knock out patients during good old-fashioned fallout-shelter surgery. High-proof alcohol can be used as an antiseptic, and it does a great job of cleaning wounds and preventing infection.
Survivalists' concerns and preparations have changed over the years. During the 1970s, fears were economic collapse, hyperinflation, and famine. Preparations included food storage and survival retreats in the country which could be farmed. Some survivalists stockpiled precious metals and barterable goods (such as common-caliber ammunition) because they assumed that paper currency would become worthless. During the early 1980s, nuclear war became a common fear, and some survivalists constructed fallout shelters.
When you go back to the last depressing days when we were in a survival mode, the last one the Y2K of course, before the 1970s, what had happened was you only saw this one element of survivalist, you know, the caricature, the guy with the AK-47 heading to the hills with enough ammunition and pork and beans to ride out the storm. This is a very different one from that: you're seeing average people taking smart moves and moving in intelligent directions to prepare for the worst. (...) So survivalism in every way possible. Growing your own, self-sustaining, doing as much as you can to make it as best as you can on your own and it can happen in urban area, sub-urban area or the ex-urbans. And it also means becoming more and more tightly committed to your neighbors, your neighborhood, working together and understanding that we're all in this together and that when we help each other out that's going to be the best way forward.
We get that creature comforts will be ever more important as the things that used to make us happy slowly break and crumble around us. But do you really want to put a ton of effort into opening a bakery when everything is going to shit? And we hate to be the bearers of bad news, but no amount of odor elimination is going to stop the uncivilized world from smelling really, really bad.
Also, many who come out here don’t seem to have taken into account ONE aspect that has already marked and recorded their interest in this/these skills. We ALL listed that we came out on here to learn in the least about it and data doesn’t get deleted or lost. (Just saying, we do have a digital fingerprint complete with email, IP address, and every letter typed.)
Cigarettes will also be hugely useful for starting fires and saving coals (as any fan of post-apocalyptic literature knows, this is of great importance). The filters can be used to clean water, although you'll need the patience of Stephen Baldwin to pull it off. If you do manage to live for longer than a few weeks without plumbing and Internet, you'll be able to protect your budding prepper garden by soaking cigarette butts in water and spraying the resulting chemical-laden tobacco juice on your produce. This is a technique already in use by people too impatient to wait for the apocalypse, though it is ironic and entertaining that they consider using cigarette-butt sludge a "natural" way to ward off pests.
You forgot one…..the invisible prepper! There are more than enough of these preppers! We have the ability to shop and store without anyone noticing. I don’t need to brag, because when the SHTF, there is going to be enough people that are unprepared and begging. We’ll just state, we are in the same boat…but little do they know. I can’t save the world, only my family.
Many books were published in the wake of the Great Recession from 2008 and later offering survival advice for various potential disasters, ranging from an energy shortage and crash to nuclear or biological terrorism. In addition to the 1970s-era books, blogs and Internet forums are popular ways of disseminating survivalism information. Online survival websites and blogs discuss survival vehicles, survival retreats, emerging threats, and list survivalist groups.
A supply of nonperishable food and water are a core necessity for every survival kit. Amazon.com offers several varieties of survival kits with emergency food for different situations. For the boat, car, or RV, high caloric density food bars are a compact and affordable way to stay safe. You’ll also find dehydrated meals in large quantities prepackaged compact bins for convenient storage. Waterproof survival kits are perfect for the basement, and contain up to three months of food for four adults.
This group stresses being able to stay alive for indefinite periods in life-threatening wilderness scenarios, including plane crashes, shipwrecks, and being lost in the woods. Concerns are: thirst, hunger, climate, terrain, health, stress, and fear. The rule of 3 is often emphasized as common practice for wilderness survival. The rule states that a human can survive: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food. 
For global catastrophic risks the costs of food storage become impractical for most of the population  and for some such catastrophes conventional agriculture would not function due to the loss of a large fraction of sunlight (e.g. during nuclear winter or a supervolcano). In such situations, alternative food is necessary, which is converting natural gas and wood fiber to human edible food.
Of all the supplies they suggest you legally or illegally procure, epinephrine sounds like the biggest stretch. We don't want to burst anyone's bubble, but if you suffer from life-threatening allergic reactions and really think you're going to survive limited food sources and practically nonexistent medical care, we've got a mint-condition fallout shelter to sell you.
Wetfire is a non-toxic product that won’t produce clouds of noxious smoke. All it takes is a tiny bit sprinkled on the camp stove to get it going even when the rain or snow is coming down in blankets. In survival situations many perish because they’re unable to create the warmth they need to counteract cold, wet conditions. Wetfire is pocket-sized survival gear that allows you to withstand nature’s worst. Wetfire has a 5 year shelf life and can be activated using any stormproof lighter or other sparking device.
If you have a proper survival knife with you when the weather closes in you can make an emergency shelter; if there’s the material available to do so. But it’s better just to make sure that whenever you venture into the woods for any length of time that you have the right survival gear with you and the Sundome 2 Person backpacking tent from Coleman is that survival gear.
Gerald Celente, founder of the Trends Research Institute, noted how many modern survivalists deviate from the classic archetype, terming this new style "neo-survivalism"; "you know, the caricature, the guy with the AK-47 heading to the hills with enough ammunition and pork and beans to ride out the storm. This [neo-survivalist] is a very different one from that".
Further interest in the survivalist movement peaked in the early 1980s, with Howard Ruff's book How to Prosper During the Coming Bad Years and the publication in 1980 of Life After Doomsday by Bruce D. Clayton. Clayton's book, coinciding with a renewed arms race between the United States and Soviet Union, marked a shift in emphasis in preparations made by survivalists away from economic collapse, famine, and energy shortages—which were concerns in the 1970s—to nuclear war. In the early 1980s, science fiction writer Jerry Pournelle was an editor and columnist for Survive, a survivalist magazine, and was influential in the survivalist movement. Ragnar Benson's 1982 book Live Off The Land In The City And Country suggested rural survival retreats as both a preparedness measure and conscious lifestyle change.
Survivalism is a movement of individuals or groups (called survivalists or preppers) who actively prepare for emergencies, including possible disruptions in social or political order, on scales from local to international. Survivalism also encompasses preparation for personal emergencies, such as job loss or being stranded in the wild or under adverse weather conditions. The emphasis is on self-reliance, stockpiling supplies, and gaining survival knowledge and skills. Survivalists often acquire emergency medical and self-defense training, stockpile food and water, prepare to become self-sufficient, and build structures such as survival retreats or underground shelters that may help them survive a catastrophe.
