What is the difference between GPS and sonar technology?

GPS (Global Positioning System) and sonar technology are both commonly used in marine navigation, but they serve different purposes. GPS determines the user's precise location by receiving signals from satellites orbiting the Earth, providing latitude and longitude coordinates. It enables accurate position tracking, mapping, and waypoint navigation. On the other hand, sonar technology is used for detecting and displaying underwater objects, water depth, and fish. It uses sound waves transmitted into the water that bounce off underwater objects and return as echoes to create a visual representation of the underwater topography. While GPS focuses on location and navigation, sonar is more concerned with underwater detection and mapping. Combining these technologies, marine enthusiasts can effectively navigate while gaining insights into the underwater environment.
