The beam dot can be seen at much greater distances than with a red laser pointer.

It can be used for pointing to star constellations (sky pointing), projection on low clouds, lab experiments, professional lectures, astronomy, star gazing, fun and games at night clubs and discos.

Use your laser pointer to point at any desired targets on projection screens, video monitors, and presentation graphics.

It is so bright that you can see the actual green laser beam itself in the dark, not just the dot.

On a moonless night, a green laser pointer beam can often be clearly seen, allowing someone to accurately point out individual stars to others nearby.
Note: the laser may not be very bright in winter. Please power it for a little while to increase the internal temperature in winter.
