Frequency and intensity dial

The frequency and intensity dials were a part of the Fourteenth Doctor's sonic screwdriver located below the resonator cage. This section of the screwdriver resembled parts of the Master's laser screwdriver. (PROSE: )

History

 * See Fourteenth Doctor's sonic screwdriver for general information about the screwdriver.

In November 2023, (PROSE: ) after arriving in the Millson Wagner Steelworks while tracking a spaceship, he used the screwdriver to project a holographic screen to analyse data, beginning the process by adjusting the dials at the base of the screwdriver. (TV: )

Behind the scenes

 * As revealed by props makers Michael van Kesteren and Barry Jones, the frequency and intensity dials portion of the sonic contained a ball detent ratchet — as Phil Sims wanted "knurled" detail on the sonic — so the dials, when turned, made a clicking noise.
