Adeptus Astartes Auspex Type 18
An Auspex, also called a Multi-scanner, or simply a Scanner are short-ranged Imperial sensor devices used to detect motion, invisible gases and energy emissions across a wide band of the electromagnetic spectrum, such as heat, radiation and most forms of energy given off by vehicles and living troops. Their main tactical use is to use the Auspex to triangulate the location of otherwise hidden enemy forces and allow them to be fired on by Imperial troops. The standard range of an Auspex is fifty metres, although walls more than fifty meters thick as well as certain types of building materials are able to block their active and passive sensor modes. An Auspex can take the form of a separate hand-held device, or its mechanism may be built into a helmet such as in the case of Adeptus Astartes Power Armour and Terminator Armour. The Imperial Guard uses hand-held scanners known as Surveyors, though the technology is essentially identical. The Space Marines and other Imperial forces like the Orders Militant of the Adepta Sororitas, the forces of the Inquisition, the Adeptus Arbites and the Imperial Navy use the Auspex. Long-ranged sensors like those used on Imperial voidships are often referred to as Augurs, though they make use of the same technology as the Auspex, save with far greater range and power when in active scanning mode.
