The Spectagraph is a next-generation device manufactured by the Weyland Corporation. It is used by geologists and engineers to survey unknown planetary terrain in the pre-terraforming process. An omni-directional laser live-maps 3D topography and sends the detailed scanned images to the viewing platform. A new hyper-conducting spherical shell allows smooth, self-propelled flight in any atmosphere. Polymer film bio-sensors can detect airborne toxins and life forms down to 500 nanometers.


  • Fifield nicknames his Spectagraphers "pups"
  • They make a cameo appearance in Aliens colonial marines twice during the second visit to the Derelict.
