Cool Tools featured green laser pointers a few months ago. Mine arrived a few weeks ago and it is, indeed, a cool tool.
The clearly visible beam of an astronomy grade laser pointer at night is ideal for pointing out stars to a group of Scouts. During the day the green dot is bight even in direct sunlight – handy for pointing out distant locations or features on a nature hike or as an emergency signal.
At several times the brightness of a common red laser pointer this is a serious tool that can seriously compromise the safety of pilots or drivers if misused – be prudent.
