Yes, there has to be "stuff" in the air. Nobody disagreed with that. But there is almost always stuff in the air. Dust, clouds, pollen, even humidity. He would have the best chance using a green laser, and in fact, more times than not, it will be very visible because theres always crap in the air, especially indoors. Cool, everybody is right!

Flaming destroys a good discussion and learning experience, grasshopper.

Green lasers are used to point out stars in the sky on clear nights. The beam is very visible.

If you are talking about the laser shot onto the sky from observatories, those are not for pointing out the stars. They are used to show currents in the atmosphere that cause distortion. Then the results are used to correct the optics of the telescope (called "adaptive optics"). They again are not normally visible except through special camera filters or reflection from stuff in the atmosphere.

No, I'm talking about the $20 green lasers that are available many places. I have a couple of them. You most certainly can see the beam at night, or inside a house. Maybe it's particulate matter, but regardless the beam is visible. The red lasers are not nearly as visible. Instead of trying to look like an expert, why not just buy one and see for yourself?

Why would anyone want a beam of light to lead someone back to their position? I have the Lasermax in my G27 and screw around with it now and then. I have no problem seeing that red pulsating light at all. I don't know if I would use it in a night fight, which I had experienced many years ago, but one thing for sure is that I certainly wouldn't want a lit neon sign between my eyes. Those lasers should be switched off as quickly as they're switched on, cause they make decent targets as well, just like those funny little flashlights that people want to stick on. I have unhappily seen a beam coming from my gun when there was a lot of humidity in the air. I'd rather leave the solid beam of light for the movies, cause that could get someone killed.

Just for you argument i have to prove you wrong im about to go take a pic of my green laser just to show you
