There are very few pieces of gear that I carry as a SUL/XUL hiker that fall into the SHTF pieces of gear. A Personal Locator Beacon (such as the ACR ResQLink 406 PLB), a multi-use compass (such as the Suunto MC-2G Global Compass), an actual real and usable whistle (such as the Storm Whistle), and the RoadID, are the four pieces of gear that I carry for the primary purpose of when/if the worst of the worst might ever happen.
Now I know there will be those out there that are going to go up in fumes over me not including a knife and a form of starting a fire, and other type of “preppers/survivalists” type of gear – and back when I was into the whole prepper/survivalist type of lifestyle I too would have been one of them. I am not going to make excuses, suffice to say that after a few thousand miles of hiking both established trails and in the process of helping to build new trails throughout California, I have come to the point where I have come to the conclusion that a person could carry a whole lot of “survival gear” and yet still never have enough, or have the right, piece of gear, for a worst-case-situation – and as a result I carry only pieces of gear that would be for the worst case, the extremely bad, situations.
When it comes to the RoadID I consider it a piece of gear that really only has a single purpose: If a time ever comes when I either die, or become so incapacitated that I am unable to speak or communicate with first responders, it will provide the first responders information about any medical conditions that I have, or in the case of me being found dead, information about who I am and who to contact. Beyond this, the RoadID is nothing but dead-weight. But oh what valuable dead weight it might someday be!
