Understanding Sonar

What is Sonar?

Sonar, short for “Sound Navigation and Ranging,” is a technology used for detecting and locating objects underwater. Originally developed for military purposes, sonar has become an essential tool for fishing enthusiasts to find and target fish. By emitting sound waves into the water and measuring how long it takes for the waves to bounce back, sonar systems can create detailed images of the underwater environment.

How Does Sonar Work?

Sonar systems consist of a transducer, display unit, and various settings to customize the operation. The transducer transmits sound waves into the water, and when these waves encounter objects or fish, they bounce back as echoes. The echoes are picked up by the transducer, which converts them into electrical signals. The display unit then processes these signals to create a visual representation of the underwater environment.
