UNIT Temporal Scanning Device (TOMT Array)

Specialized military-grade temporal sensor array used to detect unstable time vectors and temporal disturbances, located in UNIT's Temporal Research Facility.

2 appearances

Purpose

To detect and analyze temporal anomalies and jumps, providing real-time data on temporal energy fluctuations for military and scientific countermeasures

Significance

The instrument's readings directly trigger the Doctor's desperate plan to intercept the Master within his own temporal jump, making it the catalyst for one of their most self-sacrificing actions. Its erratic reliability mirrors the unreliable nature of temporal physics they're attempting to combat.

2 moments

S9E21 · The Time Monster Part 1

False detection shifts to dread of another TARDIS

The time detector suddenly activates and reveals impossible temporal readings, confusing both the Doctor and Jo as it points to an inexplicable presence nearby, shaking their confidence in the machine’s integrity.

Before: Functioning with minor calibration issues, seemingly providing erratic distance readings

After: Reactivated beyond normal parameters, emitting an impossible temporal signature forcing confrontation

S9E24 · The Time Monster Part 4

Doctor and Jo commit to temporal pursuit

The UNIT temporal scanning device provides erratic but critical readings that alert the Doctor and Jo to the Master’s imminent temporal displacement, serving as the catalyst for their desperate counterplan and guiding the Doctor’s decision to use it as a homing signal for his TARDIS insertion maneuver.

Before: Functioning intermittently after the explosion, its needles flicker unpredictably, reflecting residual temporal instability

After: Still operational but relegated to a tracking role once the TARDIS begins its temporal jump
