Dalek Command Detonation Timer

Compact spherical devices embedded in the cliffside explosives, their dull metallic casings etched with Dalek identification glyphs. Each timer features a spinning pulse wheel and a glowing countdown crystal that shifts from amber to violent red as detonation approaches. When activated, they emit a low-frequency pulse detectable by other Dalek units through their subsonic sensors, ensuring synchronized destruction even from a distance. The timers are ruggedized for field deployment, their surfaces marred by sand abrasions and faint plasma burns from previous activations. This entity includes sabotaged variants used by Jo Grant to interfere with Dalek operations, as seen when she tears one from the cliffside detonator assembly to perform a desperate act of sabotage.
