The video kept pixelating and I found that rather distracting. Otherwise, not too bad, although highly generalized - ""select the gear appropriate for your activity"? - isn't that why your audience should be learning from this video?
Two specifics - I would place a grooming kit very low on a list of survival priorities (but what can you expect from a colonist?)
A CD makes a lousy signal mirror. Its use should not be advocated. For a modest cost and equivalent weight, one can obtain and carry a real signal mirror that will actually be effective.
The emphasis on fishing isn't too useful in Arizona and vast stretches of the American Southwest, but I imagine it makes sense in Great Britain.
