Cheap and Waterproof 500mW Green Laser Pointer

This thing is way stronger than I thought. I was going to use it at work to point stuff out, but the laser beam is so bright that it feels like overkill.

Its laser beam is very bright. However, I live under a heavy flight path, and I am afraid to use it outside. If you're not careful, you could definitely get yourself into some trouble with this laser.

I bought this laser pointer to deter Canada geese from my yard. It works!
