sonar equipment

Sonar, short for Sound Navigation and Ranging, is a technology that uses sound waves to detect and locate objects underwater. It emits sound pulses and listens for their echoes as they bounce back from underwater features, such as the seafloor or submarines. There are two main types: active sonar, which sends out sound waves, and passive sonar, which only listens for sounds produced by other objects. Sonar is widely used in marine research, navigation, and fishing, helping to create maps of underwater landscapes, detect schools of fish, and monitor submarines or other vessels for safety and security purposes.
