Scanning Unit

Scanning Units are cylindrical Covenant machines.

They were used by Huragok engineers and San 'Shyuum ascetic priests to explore the inside of the Forerunner Dreadnought. Micro-sensors were fed into Lekgolo worms; once the worms tunneled through the circuitry of the Dreadnought, the worms were fed through scanning units. The micro-sensors then pinged all the data to the scanning unit.
