Allow me to add my thoughts on a PSK. I recently purchased one of Adventure Medical Kits "The Essentials" to use as my primary PSK. Along with first aid supplies, it came with:<br><br>-emergency survival blanket (their brand - with survival instructions printed on it - I haven't tried to unfold it yet to read them - too scared of having to fold it back up I guess)<br>-Brunton 9041 Glo-Mate compass (I replaced this with a Silva Landmark compass - partly out of personal preference and partly to include a mirror for signalling)<br>-Fox 40 whistle (yes, they're really loud - I tested it out in the truck on the way home - not a recommended way to do that)<br>-Storm waterproof/windproof matches (box of 25 - I plan to add a small lighter)<br>-tinder fire starter (only one parrafin impregnated ball of goo - I added a Sparklite fire starter with 7 tinders - I'll add more when I get them in)<br><br>In addition, I added:<br><br>-25 feet of paracord<br>-a Tacoma Mtn. Rescue Storm Shelter tube tent<br>-a Mag-lite solitaire flashlight<br>-a CRKT Pikes Peak knife<br>-a BCB wire saw<br><br>The whole thing comes in a soft-sided case measuring about 5" X 7" X 1 1/2" and weighs in at a bit more than one pound. This fits well in my cruiser's vest or in a hip-pack if I'm not working.<br><br>I'm sure I'll fiddle with the contents of the first aid kit. It came with latex gloves which I figure might be used in place of a condom for water carry (I'm planning on trying that out soon).<br><br>I can't help but think there's something more I should include. I'm mainly in the "sunny" Pacific Northwest so some things won't be necessary. Any suggestions or comments are welcome.<br>
