Fishing sonar displays depth, structure (such as slopes, hard or soft bottom, rocks), depth contours, and water temperature information, among other details. When fish icons appear on the screen, or if you catch a fish, note all the other data because it tells you where you might find fish elsewhere that day. For example, if you find largemouth bass congregating midway down a slope in 15 feet of water, chances are good you’ll find bass in other locations with similar characteristics.
