When choosing a sonar for fishing, consider the type of fishing you do, the depth of the waters you fish in, and your budget. For shallow water fishing, a basic sonar unit may suffice, while for deep-sea fishing, a more advanced unit with higher frequency capabilities is recommended. Look for features like GPS integration, CHIRP technology for better target separation, and side-scanning capabilities for locating fish. Brands like Garmin, Lowrance, and Humminbird offer a range of sonar options to suit different needs.
