The 1984 film established the visual and physical vocabulary of the Ghostbusters franchise, and GBFans.com's prop-building and collecting community grew directly from enthusiasm for its iconic hardware. The Proton Pack, Ghost Trap, PKE Meter, Containment Unit, and Ectomobile introduced here have been subjects of intensive research and documentation on GBFans.com for over two decades. The Equipment section of this wiki catalogues build references, production drawings, screen-accurate specifications, and community-produced plans for most of these items, along with the flight suits, belt hardware, and accessories seen in the film.
The 2022 4K Ultra HD gift set, which includes the 114-minute preview cut with early effects and alternate scenes, generated renewed community interest in comparing production-era prop and effects details against finished-film reference.
