As a minimalist in bushcraft, I rely on skill and nature to provide my tools. However technology makes tasks easy, precise and expedited. If you are a Disaster Prepper, you will rely on technology more and a survivalist or woodsman.
As a combat arms war fighter, specializing in reconnaissance in the U.S. Cavalry Scouts. I used in real world operations military grade Night Vision and Thermal Vision devices. These devices with the technology behind them were combat multipliers. Delivering battlefield advantage over enemy combatants. Providing the obvious for Soldiers, the ability to see in the pitch black darkness of night.
Sometimes the NVG's (Night Vision Goggles) were used during the day, inside buildings that had the sun blocked out. These devices also come in handy for cave adventurers. The ability to see at night as if it were daylight under stealth like conditions gives home field advantage.
Consider adding NVG's to your inventory. Be sure to stock plenty of back up batteries. These devices burn through energy cells fast. Night vision is a wonderful tool for security of your property and offers stealthy, clear, wide scope vision.
Flashlights render white light and cast illuminated beamed energy in a shape of a funnel expanding across an area. Therefore giving your position away to threats that may target you or your property.
On the market you will find plenty of night sight and night vision goggles. The best type to purchase are always military specification, otherwise referred to as Mil-Spec.
Military needs a device to be durable, long lasting and precise. So should you have these same requirements. Beware of cheap civilian knock off's. Sometimes an item might look tactical or cool, but the quality is left for much improvement. By this time you already spent your hard earned money. Be careful not to waste your cash on low quality. The best method is to shop around and test various makes and models. The idea is to buy a product you will enjoy for years to come. Outdoors expos and gun shows are a wonderful place to test these and many other amazing products at the exhibitors tables. Night vision and thermal vision devices come with various mounts and attachments. You can mount these to your helmet to your head or to your weapons platform.
Thermal vision devices are far more costly, always a better way to go if you have the disposable income to purchase. Thermal devices use heat signatures to generate a image. Sometimes allowing you to in certain cases see through a barrier or container. They also see things like friction heat for example a fresh foot print of a assailant who is running and hiding.
Being that both thermal vision and night vision can also be weapon mounted, giving you an extremely deadly advantage over an evil force trying to criminally harm or kill you or a loved one.
I never support extremism in prepping or doomsday, zombie everything must die mentality. I always teach community and infrastructure rebuilding when it comes to prepping as a focal point to recovery of our American way of life. However in recent years we have seen examples of criminal elements destroying communities to include even their own communities for personal gain. Criminals will be criminals, the law abiding citizen must be equipped to protect themselves. When law enforcement and the military are outnumbered or over tasked. These technology enhancers even the odds and tipping the scales in your favor when it comes to self-defense.
