This high quality green laser pointer will impress your coworkers, family and friends. Use it for your next presentation and everybody will know that you are ahead of the latest technology.
This laser pointer features a top precision all-metal body. Don't be fooled, some green laser pointers have a plastic body that is metalized. Our all-metal body gree laser pointer is therefore robust and durable.
This laser pointer features an all-glass lens that focuses the beam to a sharper, rounder, clearer dot.
Powered by a Sony diode with a lifetime of 3000-5000 hours, it projects a green dot up to an incredible 2 miles away. And it is so powerful that the beam itself can be seen for several hundred feet in darkness. That's why astronomers use it to point out constellations and stars in the night sky, the US Army uses it for training exercises, and executives at all levels use it to enhance their prestige.
