301/303 lazer pointer
The difference between the 2 is the 303 has a diffuser on the end that can be removed, This is the 3rd on I have bought they are neat has hell for a pointer since the green beam is visible Great for astronomy or if you have a job where you need to identify problem areas of machinery with out getting close to moving or dangerous parts, sine you can point to you subject matter from 3 miles away. The lasers have a focusable lens from a pin point beam to a larger beam area.
DO NOT SHINE THIS AT AIRCRAFT UNLESS YOU WANT TO GO TO JAIL AND SPEND THE REST OF YOUR LIFE PAYING OFF THE FINE.
THIS IS NOT A TOY AND WILL DO SERIOUS DAMAGE TO EYES. the REFLECTION FROM THIS IS VERY INTENSE AS WELL
