Drawing of an NC-2 Plotter, also called a dead reckoning tracer (DRT). The plotting surface of the desk sized DRT was about waist high, and before the advent of digital automation it was one of the most important anti-sub tools aboard a Navy surface ship. DRTs are still so useful that they are installed in ships to the present - only now, they too are digital. Drawing from a U.S. Navy training manual.
