Chart Plotter


The SPL2000 char plotter continuously indicates a ship's position on a chart and is an important tool for ensuring safety at sea.



  • A ship's position (i.e. the light mark) is continuously indicated on a chart overlaid on a plot table.
  • The plot table is large enough size to accommodate any chart currently used in the world. Large amounts of chart information can be stored in combination with a chart number.
  • The operation unit also digitally displays a ship's position.
