I, we, have noticed that if you are standing very far away from the laser,
you cannot see the beam. (not true on some of the souped up ones).
Not sure why other than you are looking "crossways" to the beam and it
isnt very thick. If you are close, then the view is diagonal through
the beam so you can see it.
That is why you see people "crowding" around the guy with the laser, it
gets pretty faint if you are very far away.
The reason I said 30 - 50 feet is that is about how far the second guy is
away from you at a star party. I am assuming that if you were "next" to
an imager, you would not do it at all.
