Here are some great uses for your laser:
Take it with you whenever you are hiking/backpacking/alone. There are quite a few reasons for this:
1) If an aggressive animal approaches, the very bright light will scare it away
2) If you get lost, this laser can shine for miles and miles (as in >100 miles!). At night, the beam is very visible. Just shine it in the sky to lead rescuers right to you.
3) This can light matches. If you don't have strike-anywhere matches and you need to start a fire, this laser can do it!
Put it in your pocket and forget about it. Why?
1) Let's say you are getting mugged. Or kidnapped. Or any other situation. Solution? Pull out your laser, expand the dot, and temporarily blind your attacker. And by temporarily, we mean you can blind him/her for hours. Now please note that this is highly NOT advised. You can get arrested for doing this... UNLESS it is self defense. So don't try it otherwise. There is a chance that it will PERMANENTLY blind you.
Use it for art. How?
1) You can cut objects out of black paper with this laser. You can also "drill" (aka burn) precise holes).
Have fun. Show it off. It can pop balloons, burn electrical tape, etc.
So what other item can you fit in your pocket that can do all of these things? A Swiss-Army Knife can't stop an attacker when he/she is more than a foot or two away. But a laser can. A GPS locater can't help you if nobody is watching your signal. But a laser will attract attention from 100s of miles away.
