How Do You Understand Sonar Fish Finders?
Fish finders use sonar technology to bounce sound waves off underwater objects. Developed during World War II to track enemy submarines and underwater mines, the technology is now used by anglers to measure water depth, identify structure where fish lurk, and to locate schooling versus solitary fish. Understanding how a fish finder works can help an angler get the most from his equipment, improving his success on the water. Turn on the fish finder, which on most models will switch to the automatic setting when activated and provide a depth-finder reading. Check the monitor to determine the water depth in feet. The measurement is calculated by the sonar when it directs a sound wave through a device called a transducer mounted on the hull of the boat. View the information on the screen as though it was a physical representation of the objects underwater. Since sound waves cannot be seen, it may be helpful to imagine a basketball bouncing up and down on a court as it is dribbled. The bask
