How to Choose the Best Fishfinder with GPS for 2025
Picking the right fishfinder with GPS can feel overwhelming with all the options out there. I’ve spent a lot of time on the water testing these units, and I can tell you it comes down to a few key things that match your specific fishing style. Let’s break it down so you can make a smart choice for your boat.
First, think about where and how you fish. If you’re mostly in shallow bays or small lakes, a simpler unit with a basic 2D sonar and decent GPS might be all you need. But if you’re chasing fish in deep water, offshore, or need to see every detail of a submerged tree, you’ll want more power. Screen size and resolution are huge here. A larger, high-resolution screen is easier to read in bright sunlight and gives you a much clearer picture of what’s below. For me, a 7-inch screen is a great starting point for most anglers, but if you have the space and budget, going bigger is almost always better.
Next, let’s talk about the sonar technologies themselves. Most units now come with CHIRP sonar as a standard, which gives you a much clearer, more detailed view than older models. The real game-changers, though, are the scanning sonars: Down Imaging and Side Imaging. Down Imaging looks like a super detailed, almost photographic view directly under your boat, perfect for spotting fish hiding in cover. Side Imaging sends signals out to the sides, letting you scan a huge area—sometimes hundreds of feet—to find structures, schools of bait, and fish you’d otherwise cruise right past. If you’re serious about finding fish, getting a unit with these features is a must.
Finally, consider the GPS and mapping. A good GPS does more than just mark a waypoint. Look for a unit that comes with or allows you to add detailed lake maps or nautical charts. Features like built-in Genesis Live mapping let you create your own super-detailed contour maps on the fly, which is incredibly powerful. Also, check the number of waypoints and tracks it can store. Networkability is another big one. Can you connect it to a trolling motor or other devices on your boat? For the 8 best fishfinders with GPS – Dec. 2025, I always prioritize units that offer a strong combination of a brilliant display, advanced sonar, and sophisticated, user-friendly mapping.
FAQ
What’s the real benefit of having GPS on a fishfinder?
The GPS is your digital memory and navigation co-pilot. It lets you mark productive spots (waypoints) so you can return to the exact same rock pile or drop-off every time. You can also follow trails (tracks) to retrace a trolling path. With detailed mapping, you can see underwater contours, identify potential fish-holding structures before you even get there, and navigate safely in unfamiliar waters. It fundamentally changes how you plan and execute a fishing trip.
Is Side Imaging really worth the extra cost?
In my opinion, absolutely, especially if you fish larger bodies of water or spend time searching for new spots. Instead of just seeing what’s directly under your boat, Side Imaging shows you a wide area to the left and right. You can scan a whole cove, locate distant brush piles, find bait schools, and see boat docks and points with incredible detail. It saves a massive amount of search time and helps you understand the underwater landscape like never before.
Can I use a fishfinder with GPS on both freshwater and saltwater?
Yes, but you need to choose the right model. Saltwater environments are harsh on electronics. If you fish in saltwater, you must look for a unit that is explicitly rated as waterproof and corrosion-resistant. Many manufacturers offer specific saltwater-series models built with tougher materials and better seals to withstand the marine environment. Always check the product specifications for its intended use.
How difficult is it to install one of these units myself?
Most modern fishfinders are designed for a straightforward DIY installation. The basic process involves mounting the display unit at your helm, running a cable to a transom-mounted transducer on the back of your boat, and connecting to a power source. The trickiest part is often routing the cable neatly. Many brands provide good instructions and template guides. If you’re not comfortable with basic wiring or drilling into your boat, having a professional do it is a wise investment to avoid costly mistakes.
What’s the difference between pre-loaded maps and creating my own?
Pre-loaded maps, like those from Navionics or C-MAP, give you a great starting point with general lake contours, depths, and landmarks. Creating your own maps, with a feature like Humminbird’s Auto Chart Live or Garmin’s Quickdraw Contours, takes it to another level. As you drive your boat, the sonar data builds a highly detailed, custom map of the bottom. This reveals subtle contours, holes, and structures that standard maps often miss, giving you a significant edge on your home waters. For anglers looking for the most detailed information, this custom mapping is a top feature to look for in the 8 best fishfinders with GPS – Dec. 2025.
