Projector Dowser

Share this page:

Inexpensive digital projectors are used on shows everywhere but they have a problem that is difficult to overcome:  When they fade out, they still project light, called “video black”, and this small amount of light is easily visible during a stage blackout.  Our Projector Dowser is a simple DMX (or contact closure) controlled flag that can be closed in front of the projector’s lens when you need a complete blackout.  An included mounting plate allows a variety of hanging positions to suit your production’s needs.
