Scanning Units are cylindrical Covenant machines.[1]

Role Edit

They were used by Huragok Engineers and San'Shyuum ascetic priests to explore the inside of the Forerunner ship, 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.
