The 1.0 mW beam is a perfect pointer for A/V screens, walls, charts, or blackboards. It can be modulated to transmit voice or video and perform light speed measurement experiments (you must provide your own receiver). The compact size makes it easy to hold. It also features a 3-position power switch, a momentary pushbutton switch and aperture beam shutter. Power is supplied by rechargeable batteries or the external AC adaptor.
