Learn how to use it – What good is a compass if you don’t know how to use it? Not much. How about your Tenacious Tape? Or your GPS locator, or multitool? It’s great to head out into the wilderness with all the appropriate survival gear but if you don’t know how to use it when the time comes it will be as useless as the “g” in “lasagna”. Once you’ve decided what you need and have purchased everything take the time to familiarize yourself with what you have and how it works. Take the GPS locator out into your local state park and practice with it. Practice starting a fire with your emergency fire starter. Buy some extra Tenacious Tape and a cheap raincoat and practice cutting it up and making repairs. Take your survival knife out on a short hike and see what its practical limitations are when it comes to cutting wood etc. You might need a larger one or one with a longer serrated edge. The bottom line is this: make sure you know how to use the survival gear you have before you leave civilization behind and head into the woods.
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.
Each type you listed (save a couple) will have its uses in a community (group if you will), generally having a small trusted group with each having several skills in the various fields (prepper, homesteader, and survivalist) I believe would be an effective team, though as each group works together would it not be best to ensure that each has overlapping skills in case of injury, death, or other reasoning they can not fulfill their duties?
With goTenna you use a simple smartphone messaging app as a platform for sending SOS messages along with your handheld hunting GPS coordinates should you need emergency help. You can also use it to chat with emergency services so they know your exact condition and can prepare accordingly. It’s off-grid survival gear at its best and could be the difference between life and death.
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.
The kits provided for Soviet and Russian Cosmonauts are optimised for survival in the temperate and sub-arctic mountains, forests and grasslands in the east of the country. Soyuz spacecraft kits include "food rations, water bottles, warm clothing, rope for making a shelter using the capsule’s parachute, fish hooks and miscellaneous other survival gear". The TP-82 Cosmonaut survival pistol, was provided to defend against predators such as wolves or bears. It was able to fire conventional bullets, shotgun cartridges and flares; the folding stock could be used as a shovel and it also had a fold-out machete.
These individuals study End Times prophecy and believe that one of various scenarios might occur in their lifetime. While some Christians (and even people of other religions) believe that the Rapture will follow a period of Tribulation, others believe that the Rapture is imminent and will precede the Tribulation ("Pre-Trib Rapture"). There is a wide range of beliefs and attitudes in this group. They run the gamut from pacifist to armed camp, and from having no food stockpiles (leaving their sustenance up to God's providence) to storing decades' worth of food.
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.
