To monitor temporal displacements and track the positional shifts of individuals or objects moving through time and space

Significance

This device allows the Doctor to detect Lupton’s deviation in real time, exposing the villain’s strategy and the escalating danger of their path. Its use foreshadows the growing psychic threat radiating from the crystal’s movement and forces UNIT to confront the fact that conventional pursuit cannot intercept Lupton’s temporal trail.

Before: Operational but subjected to intense vibration and erratic energy spikes as unstable residual power surges through its components

After: Continuing to function despite worsening conditions, now integrating new directional data that reorients the chase toward inaccessible countryside
