Good thoughts and does cause one a reflective pause.

Eyes wide open should be the watchword. Obviously the unit has limitations. It stands to reason the battery would have to be of small to else the unit would be unable to be placed in unobtrusive places.

I watched some climbing video at mt rainier done with the go pro and one comment was the battery died in the cold. Small battery and video footage seems a bad combination and yet the potential for some memorable usage is obvious.

Quite a bit of informative material on utube I have yet to view including battery life tips. I will probably pull the trigger eventually if for nothing else to get hassle free fish pics. I go canoeing to avoid hassle if possible and this just might fill a useful purpose.
