Pointer
The Laser Pointer projects a visible bright red spot of light several hundred feet under normal lighting conditions-great for lecturers with slides. The $800 helium-neon laser has an output of 0.5 mWâ€”not enough to harm eyes or body, says RMF Products, Box 413, Batavia, III., 60510.

Ahh, 1981… the start of the Enddays for Motion Picture Theatre managers. (Of course, at that time, very few audience members had a spare $800.)
