The Ecto-Magnetizer was part of the original Ghostbusters equipment which they carried with them in their Ghost Pack. It was similar to a vacuum cleanera and was attached to a separate power source by way of a cable. Therefore, at least two people had to work simultaniously to use the Ecto-Magnetizer. One to switch on and man the power source while the other held up the magnetizer itself to suck in ghostsly adversaries. Jake Kong Sr. used the Ecto-Magnetizer to capture Slort, King of Trolls while his son, Jake Jr. manned the power source.
