Interpreting sonar data is crucial for successful fishing. When reading sonar, look for arches, which indicate fish presence. Pay attention to the depth of the fish, as well as the size of the arches. A larger arch usually represents a bigger fish. Additionally, watch for baitfish schools, as larger fish often lurk nearby. Use the fish icons on your sonar to differentiate between fish and structures. Experiment with sensitivity settings to get a clearer picture. Finally, learn to distinguish between different types of bottoms, as fish tend to gather around structure-rich areas.
