Deep Core Surveyors are deep tunneling units that search the core of a planet for additional resources. They operate autonomously and may discover new veins of any of a variety of valuable resources. Construction of multiple Deep Core Surveyors can be quite useful, but the benefits of building more than one drop off in a nonlinear fashion. Deep Core Surveyor are energy hogs, consuming an impressive 100,000 Power per turn.
