Sonar System
A Sonar System is a tool that helps people find and track fish, map the ocean floor, and measure water depth using sound waves. Think of it like an underwater radar - it sends out sound signals and listens for echoes to create images of what's below the water. Fishing vessels use sonar to locate fish schools, check the seabed condition, and navigate safely. There are different types, from simple fish finders to complex scanning systems. These tools are essential for modern commercial fishing, marine research, and underwater surveying work.
