I usually take my point and shoot out with me, and do keep an extra set of batteries for it in my kits (2 x AA), but I don't consider it a survival aid. I could use the batteries and lens for fire starting, and could probably use the plastic housing to collect a little water, but my only thought real thought when packing it is to take pictures for the family photo album.

My son and I often use the pictures as post-trip conversation starters about survival skills, resources and tools, so I suppose we could could consider the camera a survival aid in that it helps better prepare the brain? That's the most important piece of survival gear we have, right?
