Significantly brighter (about 50 times) than a red laser pointer and much more noticeable to the human eye (the green wavelength of 532nm appears brightest to the eye), the uniform round beam yields superior quality at long distances compared to most elliptical red laser pointers. And unlike a red laser, the green beam can be seen in mid-air in dark conditions rather than just the pointer beam dot. This allows you and your audience to follow the direction of presentations, lectures, star constellations, clouds, skypointing and signalling. All eyes and audiences will love you for it.
