Laser pointers are an effective means for directing attention in the class on smartboards and projection screens, at planetariums, even against the sky to point out actual constellations! This green laser pointer pen features a cool, high-contrast 532 nm green beam that stands out in almost any environment—you can even see the beam itself (not just the dot) in the dark.
Laser pointers prove essential in the audio industry by allowing installers and do-it-yourself users to properly align speakers and check for first reflections by placing the laser pointer perpendicular to the front of speaker cabinets. Great for placing wall mounted sound absorbing wall panels and damping panels.
Powered off of two AAA batteries (sold separately, please see the Related Items section on the right for recommended batteries), this slim pen-sized laser pointer tucks away in pockets, while the convenient pocket clip keeps it ready to go. A non-slip, rubberized coating allows for a confident grip in nearly any condition. Includes laser-cut foam-padded carrying case.
Caution: Do not stare directly into the aperture of the laser pointer. Do not point at other people's eyes. Keep out of reach of children.
