The ghostbuster device was a device used by Miles Straume at Mrs. Gardner's house. Entering the room of Mrs. Gardner's murdered grandson, Miles placed it on the table, turned it on, and sat on the bed, waiting to contact the spirit. ("Confirmed Dead") The device did not actually contact the dead; it was part of a con, as this was not how Miles' mediumship worked. Miles brought the ghostbuster device case to Howard Gray's home, but did not open the case and did not make use of the device. ("Some Like It Hoth")
