The Goa'uld long-range visual communications device is used for communicating over distances. It projects both a visual and audio signal within a spherical shape, similar in its function to a television, but much more advanced. The device comes in a variety of sizes from very large to palm-sized, and may be used for public addresses as well as private personal communications.
