Time Converter

The Time Converter was a handheld device possessed by Sarah Jane Smith. It allowed the detection, opening, and closing of time fissures where the Web of Time was thin. Fearing that she might use it to alter her timeline as she had recently, Sarah Jane destroyed it. (SJA: The Temptation of Sarah Jane Smith)


 * It had some functional similarities to the Tenth Doctor's timey-wimey detector (and similar devices) and functioned like a small scale Rift Manipulator. Like the Rift Manipulator it could, indirectly, enable the user to travel through time.

Behind the scenes
The Sarah Jane Adventures website describes its origin as unknown and says that the Converter "[could] manipulate time energy in order to create time fissures between fixed points in time. But be careful; these time fissures are very temperamental and could shut at any time!"
