Anyone who has used a laser on a brightly lit jobsite knows how difficult it can be to see the laser beam. Johnson's green beam laser enhancement kit gives you the tools you need to quickly and easily detect the beam from any green beam laser tool, saving you time and frustration on the jobsite. The kit includes a target that enhances the brightness of a laser beam and comes with graduations in both inches and centimeters. The target is also magnetic, so it attaches easily to metal surfaces for convenient, hands-free use. To further help you see green laser beams, the included laser enhancement glasses sharpen any green laser beam for easy visibility. If you also use red beam lasers, consider Johnson's red beam universal detector kit (Model 40-6720) for our full lineup of red beam detection tools.
