I was reading an article somewhere about the contents of their day pack. They carried a laser pointer with them for a signaling device. Claims can be seen line of sight for miles. I use one at night with my telescopes and can say you can see beam pretty far with it. I guess it would be good for a night emergency signal. Anyone carry one in their survival pack?
Another question: What color do you think would show up better? blue, green or red?

But I suppose it would fade out if your target is too far away.
