Fish finders use various symbols to represent different types of fish or objects detected underwater. Common fish symbols include arches, fish icons, and fish alarms. Arches are the most reliable indication of fish as they show the actual sonar return from a fish passing under the transducer. Fish icons are simplified graphics that represent the presence of fish, but they may not always be accurate. Fish alarms are customizable alerts that notify you when fish or a certain size of fish is detected. Understanding these symbols can help you interpret the information displayed on your fish finder accurately.
