Belt Gizmo

The "Belt Gizmo" is a device worn on the pistol belt. While its purpose is unclear, it is commonly thought to be a type of read-out or warning system for the Proton Pack. Featured in both films as well as the 2009 video game, it is nonetheless an integral part of the Ghostbusters' equipment.

The main circuit board sits in a modified tape measure holder and connects to a smaller "daughterboard" via a black coil cord. The display is normally comprised of eight nixie tubes and an error box (although stunt versions had anywhere from 9-11 tubes).

For the early NYC shooting of Ghostbusters, the Belt Gizmos were made from **Sanyo ICC-808D **calculator circuit boards; these were badly damaged during production and were replaced with rubber stunt versions used for the rest of the LA shooting.

The daughterboards simply appear to be cobbled together pieces of circuitry, wires, and wire caps. As evident in the few screen shots and stills available, no two daughterboards are the same.

In some of the early promotional photos Ray's coil cord connects to his chest pocket. The main circuit board also appears to be badly damaged.
