Buying Guide: What to Look For in a Fish Finder GPS Combo
Sonar Technology: CHIRP, Side Imaging, and Live Views
Modern fish finders use CHIRP sonar for crisper targets and better separation. Side imaging lets you scan wide areas to locate structure, while DownScan or Live View gives real-time visuals of fish approaching your lure. The best fish finders balance these technologies to suit your fishing environment, whether you’re in deep lakes or shallow rivers.
For example, the Humminbird XPLORE 9 offers MEGA Side Imaging+ with a 200-foot range per side, ideal for covering water quickly. The Lowrance Eagle Eye 9 takes a different approach with Live Forward and Live Down views, letting you watch fish react to your presentation in real time. Consider which sonar type matches your primary tactics.
GPS and Mapping: Built-In Charts vs. Custom Mapping
GPS is more than just a waypoint marker; it’s your navigation hub. Look for units with preloaded maps covering thousands of lakes, like Humminbird’s Basemap, or the C-MAP charts on Lowrance. If you fish uncharted waters, AutoChart Live or Quickdraw Contours let you create your own depth maps as you boat.
For kayak anglers, compact units like the Garmin Striker Vivid 7cv offer Quickdraw Contours and easy waypoint marking, perfect for small watercraft. If you’re exploring new lakes, having a reliable GPS is as crucial as sonar. Our best kayak fish finder covers more on this topic.
Display Size and Screen Quality
A larger, high-resolution screen makes it easier to interpret sonar returns and navigate maps. The Humminbird XPLORE 9 boasts a 1280×720 HD display with touch and keypad controls, while the Garmin Striker 4 offers a compact 3.5-inch screen for simple, portable use. Think about where you’ll mount the unit and how much viewing distance you need.
For ice fishing, a smaller screen like the Garmin Striker 4 works well because you’re sitting close. For a boat console, a larger display reduces eye strain. Consider sunlight readability and viewing angles when choosing.
Transducer Quality and Included Accessories
The transducer is the heart of your sonar system. Bundled transducers vary in capability; some offer multiple frequencies and scanning modes. For instance, the Lowrance Eagle Eye 9 includes a transducer that supports Live, CHIRP, and DownScan, eliminating the need for an external module. The Garmin Striker Vivid 7cv comes with a GT20-TM transducer for CHIRP and ClearVü.
Check if the transducer is transom-mount or can be adapted for trolling motor or ice use. If you plan to use the unit on different boats, look for portability options. For trolling motor integration, see our best transom mount trolling motor.
Final Thoughts
Choosing the right fish finder GPS combo comes down to your fishing style and budget. For serious anglers who want premium sonar and advanced mapping, the Humminbird XPLORE 9 GPS Fish Finder is a powerhouse with MEGA imaging and a large HD touchscreen. If you’re looking for a versatile, mid-range option with live sonar views, the Lowrance Eagle Eye 9 Live Sonar Fish Finder offers excellent value and real-time fish observation. Both deliver reliable GPS and superior fish detection, ensuring you spend more time on productive water.

How does side imaging differ from down imaging?

Do fish finder GPS combos come with preloaded maps?
