Belt Gizmo

The "Belt Gizmo" is a device worn on the pistol belt. While its true 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 later boards 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, which were most likely destroyed during production. New Belt Gizmos were built for the LA shooting, which were either redressed Sanyo boards or scratch-built replicas.

As evident in the few screen shots and stills available, no two daughterboards are the same.

Instead of nixie tubes, these props feature rainbow ribbon cable inserted into clear plastic tubing. Although these were the only Belt Gizmos built for GB2, fans frequently refer to them as "stunt boards" due to their shoddy design. Ernie Hudson's GB2 Belt Gizmo The Belt Gizmos seen in Ghostbusters: The Video Game appear to be styled after the GB1 replica boards used during the LA shooting. Screencap by Jack Doud The Belt Gizmos were given a new design in the animated series The Real Ghostbusters. Like in the films, no explanation is given as to their purpose.
