Which is better for an audience watching a presentation using a wireless presenter, one w/a green laser or a red laser?

Which is better for an audience to see a presentation by using a presenter, a green laser or a red laser? I have no idea at all. From what is advertised, some manufacturers seem to think the green is easier to see? Any students here that can tell me which is better from their college classes? Or does anyone else have an idea?

Will actually depend on the brightness of either one. There are some red ones that are so weak, they are useless and green ones that are so bright, that even at 30 feet they will be distracting people. I'd go with a good quality red one or a weak green. Green is a bit easier to see, btw.

I think that's a short sighted comment without knowing what the actual presentation is about. Some diagrams and schematics cannot be "clean enough" where all of the audience will quickly understand what is being referenced. Ever seen even a basic SEPIC design?

The big advantage to green lasers is you can see the beam in a lighted area as red the beam will look invisible.

Is that really true? Wonder why that is? That is an advantage if true. No more dimming the lights around the presentation screen?

Most green pointers are considerably brighter than red. You can spend $7 online to get yourself one and play around with it.
