Named for it’s use of kitchen utensils, the KUD Meter appears in Ghostbusters 2 and is used by Winston when the Ghostbusters first investigate the museum. The main body is made from a Micronta 3001 metal detector. These are regularly on ebay, the 4001 is almost identical in shape with an additional red button on the top of the handle. The scan head is cut off and a strainer and potato masher are added in place.
