Buying Guide
Side Imaging Coverage and Detail
Side imaging is the star feature for many anglers, allowing you to see fish and structure to the left and right of your boat. Look for models that offer MEGA Side Imaging or similar high-frequency technology for sharper images with better target separation. The Humminbird Helix 7 G4 and G4N models, for example, provide coverage up to 125 feet on each side with three times more detail than standard imaging.

GPS and Chartplotting Capabilities
A built-in GPS with preloaded charts helps you navigate unfamiliar waters and mark productive spots. Models like the Lowrance Elite FS 7 come with C-MAP Contour+ charts that reveal lake contours, while Humminbird units include Basemap coverage for over 10,000 lakes. Real-time mapping features such as AutoChart Live let you create custom depth maps as you fish. If you fish from a kayak, you might also explore our kayak fish finder recommendations.
Sonar Technology and Fish Targeting
Modern fish finders combine multiple sonar types to give you a complete underwater picture. CHIRP sonar provides crisp 2D fish arches, while DownScan Imaging shows detailed structure and cover. FishReveal technology, found on Lowrance models, merges CHIRP fish targets with DownScan imagery so you can see exactly where fish relate to structure. For those who want live sonar feedback, the Lowrance Eagle Eye 9 offers Live Forward and Live Down views. This is a game changer for watching fish react to your lure in real time.
Display Quality and User Interface
A clear, bright display is essential for reading sonar returns in direct sunlight. Screen sizes range from 7 to 9 inches in this price bracket, with IPS panels offering wide viewing angles. Touchscreen models like the Lowrance Elite FS 7 provide intuitive control, while keypad-based units such as the Humminbird Helix series are reliable in wet conditions. Consider your mounting location and how you prefer to interact with the device. For more on side imaging fish finders, visit our side imaging fish finders category page.
