The Mini Carbon Dating Machine is a Gadget used in the episode “The Dusk of Dawn”. It is the size of a screwdriver with a section that resembles an hourglass. It can be used to detect the precise age of even the most ancient of artifacts. Alex tries to use it on Jerry, only to comment that it doesn't work on him. The spies use it later to pinpoint Cheston's cloak to the 13th century, 1246 CE, in March, on a Tuesday, at 4:37 pm.
