Ghost Trap

A piece of ghostbusting equipment almost as important as the proton pack in the Ghostbusters universe, the ghost trap was used for detaining and transporting "busted" ghosts until they could be safely stuffed into the Ecto Containment Unit. Believed by some to entrap the ghost with a laser containment field, precisely how the trap works was never fully explained in the films. Although the traps look similar in both Ghostbusters 1 and 2, there are subtle differences in several details as well as overall shape. This picture represents a trap from the first film.
