This green laser pen is a commonly used product for meetings and conferences, let you speak out freely.Best guide for the climbers and people in mountainous areas. Good tool for pointing out the faraway target and sending out the SOS signal, making your travel more fun. This green laser pen can measure you the accurate position of the building in the faraway distance by avoiding going close to the dangerous field.Lightweight and handy, Output wavelength: 532 nm.The beautiful beam light is extremely suitable use at night, which can point out the very right position of the star you are looking at.Avoid direct eye exposure to laser beam. Don't keep the laser on continuously for more than 60 seconds or it will get burnt from inside easily.
