Time to talk about my PSK (Personal Survival Kit). This is nothing more than an upgraded PC kit. This is something I can carry in a briefcase, etc. This can supplement or replace the PC kit.
My PSK Kit:
Quick To Don Survival Necklace:
* Swamp Warden with Kydex Sheath
* Light My Fire "Army Model" Firesteel with Striker
* All three items strung on SAFETY ORANGE Paracord
Improved Defense:
* 9mm Handgun (minimum)
* (2) Spare Magazines (minimum)
Improved Shelter:
* Emergency Space Blanket
* Emergency Disposable Poncho
Improved Water:
* Collapsed Platypus 1L Water Bag/Bottle
* Aquamira Survival Water Filter
* (3) Katadyn Purification Tablets
Improved Navigation:
* Compass
* County Comm Maratac AA Flashlight
More On Water:
I always carry one or two Nalgene or a couple of .5 L bottles of water with me. I keep a case of water in my work vehicle (rotate/replace the car case after I drink the case sitting in my office).
This kit doesn't contain a lot of gear, but the kit is light and small. This is a minimalist kit, but my chances of surviving are GREATLY increased with these basic resources.
