To add a discussion point, I must admit that I'm suprised at the lack of first aid kits in most peoples responses.
Why is this the case?
Kind regards
Mick
hey Mick, I can't speak for anyone else, but, most FAK's (as compared to comprehensive medical kits) include bandaids, some pain pills, toothache drops, etc., usually nothing that would make a difference between life and death, at least in the short term (remember I'm generalizing). OTOH, shelter, water and fire can definitely be life and death considerations both in the short term and long term, more so in some environments than in others.
Now if the scenario was set up that you were injured and in a survival situation, I'm sure a lot of the answers would be different. And I'm certainly not trying to downplay the importance of a FAK as part of an overall strategy, but the OP restricted us to 3 choices, and injuries were not part of the scenario.
Rest assured, when I canoe, etc., I have a fairly comprehensive medical kit, at least one that's commensurate with my limited abilities.
As far as my choices go, I would have like to see 4 rather than 3, but since we were limited, I based my choices on which necessary items would be the most difficult for
me to reproduce.
A water proof shelter with natural materials is certainly doable, but can take a lot of time, not a good idea if you're trying to hike out and have to remake one every night, so a tarp is a god send. In some conditions, getting wet could be a death sentence. So, a tarp is my first choice (not in any order of importance).
Sanitized water, being a fairly immediate necessity, must be both available and be able to be carried. Once again, doable, but not easily, at least for me, so the Guyot is #2.
As far as the knife goes, I can find some substitutes, but nothing is going to come close to a large blade, for shelter, firewood, defense, not to mention piece of mind, and for all the smaller jobs like tool and trap building, so a machete or Khukuri, actually my Machax would be the third one.
#4 would be a monster ferro rod or a case of Bic lighters!
Anyway, that's my thinking, YMMV,
Cheers,
Doc
