Boats use echoes through a technology called sonar, which stands for Sound Navigation and Ranging. Sonar emits sound waves that travel through water and reflect off objects, such as the sea floor or other vessels. By measuring the time it takes for the echoes to return, boats can determine distances, map underwater topography, and detect obstacles or marine life. This helps improve navigation safety and aids in fishing and research activities.
