fishfinding sonar

Fishfinding sonar uses sound waves to detect underwater objects like fish and the seabed. The device emits sonar pulses that travel through the water, bounce off objects, and return as echoes. A receiver interprets these echoes to create visual representations on a screen, showing fish, structure, and depth. Think of it as echolocation—similar to how bats navigate—allowing anglers and boaters to locate fish more easily and understand underwater environments efficiently.
