i am looking to buy a green or purple thick powerful laser beacon that has a thick beam so when I shine it at the sky when I'm camping I can point out the stars and such, or use it as a signal to be rescued. is something like this exist? I saw one about 5 years ago when I was on a camping trip...
Does anybody have reviews on this laser? Can it light a match? Can it pop any kind of balloons? Can it light a candle.? I'm trying to decide between 1w and 700mw.
And what are good googles I should get...
