While this is 'interesting' I think it may be too narrow in it's usefulness - such as needing an element in the middle of the stack means having to unpack all or most of it to get to it. I also wonder if the tube/container could be re-purposed some how when the contents are needed so it is not just a container.

I would like it a lot better as a storage/deployment item where it included a small bag/pack or some way to carry the stuff once the tube is opened for use. It's great for having all the components in one grab & go kit but it isn't a good design for ongoing use. Something like this could be used to drop a kit to someone stranded to use until help arrives but would need an instruction section to go with it.

As for training - that is truly the key... having the right equipment to go with it is best. However, having a bunch of tools and no idea of how to use them makes the tools more or less moot.
