A chart plotter is a specialized electronic device used in navigation, primarily on boats and ships. It displays nautical charts and helps mariners determine their position using GPS technology. By integrating various data sources, a chart plotter provides real-time information about the vessel's location, speed, and course, making it easier to navigate safely. These devices often come with features like route planning, waypoint marking, and weather updates. Many modern chart plotters can connect to other equipment, such as radar and sonar systems, enhancing overall navigation capabilities. They are essential tools for both recreational sailors and professional mariners.
