Scanning unit

Scanning Units are cylindrical Covenant machines.

Role
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.
