Dalek Lifeform Perceptor (Used by Dalek 2)

A scanning sensor device wielded by Dalek 2 to detect and track lifeforms in enclosed spaces like caves. Its initial failure to register the TARDIS crew prompts Dalek 1 to deploy the Electrode Unit for seismic testing, creating a causal chain in the Daleks' hunt.

Purpose

Scanning enclosed spaces like caves to detect and track lifeforms or objects

Significance

False negative reading forces Daleks from passive monitoring to aggressive mobilization, including electrode deployment and assault on the Mechanoid city, as the crew advances unaware into towering architecture.

Daleks detect escape and mobilize pursuit

The perceptor, held out by Dalek 2, is used to scan for the TARDIS crew's location within the cave. Its failure to register the humans' presence contradicts initial readings, prompting Dalek 1 to order a seismic detector test. This device plays a crucial role in the Daleks' pursuit, highlighting their reliance on advanced technology to track and capture their targets. The perceptor's inaccuracy underscores the tension and uncertainty in the Daleks' hunt.

Before: Functional and held by Dalek 2, scanning the cave for the TARDIS crew's vibrations.
After: Determined to be inaccurate in its readings, leading to the deployment of the seismic detector.
