Point out constellations with this high powered 500mW laser. Light matches, pop balloons, and engrave with this laser. Contractors love them for on-site work, pointing out areas and work that they can't physically reach, landscapers can point to areas in trees and on houses that are too high up. The dot can even be clearly seen over 100 yards away in broad daylight. At night, throw on the refractor for "party mode" and see hundreds of dots in a kaleidoscope pattern. With an 18650 rechargeable battery, battery wall charger, and keys to lock and disable the laser, this package has everything ready to go as soon as you open it.
