Lasers in clubs

i was wondering how people r using so powerful lasers in the clubs do they know how dangerous they can be ?

As far as I know, the scanners they use are so extremely fast that the flash time is so minuscule and it doesn't really matter too much.

plus isn't crowd scanning illegal? (at least in the us)

Yeah usually no crowd scanning. Another HUGE factor for lasers in clubs is the haze. Clubs theatres etc use hazers, not fog machines. the smoke particles in a hazer are alot less dense than fog machine ones, so you get a good amount of haze in the air. I found even the 40mw green in my RGY was enough for a big hall, and we used a hazer. THey make a big difference it the appearence.
