Cheap 1W Laser pointer is real?
That's why today's astronomers, military, serious business professionals, and educators use high-powered green laser Pointers. Mini handheld green laser pointer is available in a variety of watts. Class II or 1MW green laser Pointers and Class 3A 5MW green laser Pointers are the safest. It is actually against US regulations to use green laser Pointers with a high power laser beam of more than 5MW in a public environment. Anything more powerful than Class II 1MW or 3A 5MW is not necessary for demonstration or even armature astronomy. The laser beams and points of class 2 1MW and 5MW green laser Pointers are very powerful and visible in dark or bright conditions.

With so many cheap green laser pointer and branded manufacturers on the market, choosing the best green laser pointer can be a daunting task. After all, lasers will never be safe if you use them the wrong way and use them the "wrong" way. So you can choose the best for your needs, know how to test for defects, and get a warranty or guarantee for the product. Leave some signal material behind when leaving danger in case rescuers find it. Ground signals are important, so you can set up rescuers or a last position and direction indicator marker to help them find a way to understand your movements. On the way out of the pointer, do not show the rescuers, if they want to return, it will not be lost - if lost, can not find the way, want to walk, he can become a magician.
