You were right with the assessment that is was an overnight kit, but I don't see the reason to then turn around and try to turn it into a 72 hour kit. I don't see ANY pocket kit as 72 hour kit- not this, not the PSP, not the BCB tin, or anyone's home build. Overnight, and then go from there, but that is becuase the tools are the same- the difference is in the consumables. The lack of the aluminum foil isn't as minor as the lack of the sewing needle, but it is a quibble given the role of this kit.

Personally, I don't think they needed the fishing kit in it, but I explain my theory as to why it is there in another post in this thread.
