The Doctor's Energy Scanner

A palm-sized device the Doctor extracts from his pocket, its surface unadorned but for a single glowing dial on top. It emits a steady beep when powered on, then emits a high-pitched tone upon detecting the anomalous energy readings in Tubney Wood. The Doctor holds it aloft like a compass, orienting himself toward the source of danger, its readings guiding him past the environmental distortions to the android enforcers.

Purpose

To detect and locate sources of unusual energy, particularly anomalies caused by advanced alien or synthetic technology.

Significance

A critical scientific tool that functions as the Doctor's early-warning system, allowing him to identify and navigate toward existential threats before visual confirmation is possible. Its beeps become the first audible sign that something is gravely wrong in the tranquil woodland.
