This round device measured three meters in diameter, with a central holoprojector set into a hologram pod. Scanning and projection panels were located around the perimeter of the central projector, which could create an image many meters in height. A control panel was located on the side of the pod, along with cooling vents and a field limiter. The SoroSuub projection pod, like all other HoloNet transceivers, could receive and decode HoloNet transmissions sent along S-thread channels from anywhere in the galaxy. Because of the widespread implementation of the HoloNet, the projection pod had an effective range that spanned the entire galactic disc.
SoroSuub projection pods were commonly installed on the bridges of Imperial Star Destroyers, and one was also found in the holoprojection chamber aboard Executor during the Galactic Civil War. Vader used this to communicate with Emperor Palpatine to report on the progress of the war, and during the pursuit of Millennium Falcon following the Battle of Hoth in 3 ABY. Palpatine altered the transmission settings to project his image many times its actual size, to the extent that it usually only showed his head; a technique he used to intimidate his subordinates. The field limiter also ensured Prince Xizor, who was at the Emperor's side during the holotransmission, was not seen by Lord Vader. Grand Admiral Thrawn also used a hologram projection pod to inform Captain Gilad Pellaeon of his arrival. While in Mount Tantiss Joruus C'baoth discovered Palpatine's settings and used that setting when communicating with Thrawn. During the Virgillian Civil War, the Virgillian Free Alignment installed a HoloNet transceiver in the Quasar Fire-class bulk cruiser Flurry which they had stolen from a captured Imperial vessel. This was unusual enough that Navy commander of the Imperial fleet at Bakura noted that it was probably stolen.
