That’s because, like kayaks, electronics are better than ever, and they add a lot of capability to a kayak. If you want to upgrade your yak, here are the best kayak fish finders. - **Best Overall:** [Lowrance Elite FS 7]() - **Best Budget:** [Helix 5 Sonar G2]() - **Best Under $200**: [Garmin Striker 4]() - **Best for Saltwater:** [Humminbird Helix 7 CHIRP SI GPS G4]() - **Best for Tournament Angling:** [Garmin LiveScope Plus]() - **Best Battery:** [Dakota Lithium 12V 10Ah]() - **Best Battery Box:** [Yak-Power Power Pack]() ## Best Kayak Fish Finders: Reviews & Recommendations ### Best Overall: [Lowrance Elite FS 7]() I don’t always use a fish finder while kayak fishing, especially when I’m fishing shallow water, but the times I do need one, they’re absolutely critical to my success. I’ve been using my Elite FS 7 for summer crappie fishing, which is difficult because the fish move constantly, chasing schools of baitfish. So the hard part is finding them and staying with the school. I have the 3-in-1 Transducer and primarily use the down scan for summer crappie. I’ll peddle my Old Town Sportsman Big Water PDL around likely areas like submerged brush piles until I find a school. Then I’ll drop my jig down until it hangs in their face. Schools of crappie and the cover they hang around to show up plain as day on the screen. I’m no video game fisherman, but I have no trouble finding fish with the down scan. I also use my electronics heavily while fishing for saltwater species like striped bass, flounder, sea bass, and sheepshead that hang around structure. I’m not necessarily marking fish while targeting those species, instead, I’m using electronics to find slight changes in depth and key pieces of structure. When I’m cruising around, I like to use the side-scan feature to cover the most area, and then I’ll switch to down scan once I see something I like. I recommend taking advantage of trying different color palates for the side scan until you find one that you like best. I personally like the yellow and black contrast. ![Lowrance Eliite FS 7 side imaging]() *Side scan helps you cover water quickly. Scott Einsmann* I used the [YakAttack Rectangular Fish Finder Mount ]()to attach the Elite FS 7 to the forward gear tracks on my kayak. The transducer mounting took some minor modifications because my Old Town is most compatible with Humminbirds. But, it was nothing that a little time with a power drill and a quick trip to the hardware store for stainless bolts couldn’t fix. Running the transducer cable was easy in my yak, and wiring the power source was also easy. The mapping on the Lowrance is excellent, and the touchscreen makes it easy to scroll around the map to find ledges, drop-offs, or map your route. If you’re scouting an area at home, you can view your fish finder’s map on an iPad by connecting it via WiFi. ### Best Budget: [Humminbird Helix 5 Sonar G2]() The Helix 5 Sonar G2 was the first kayak fish finder I bought, and I still use it on my Jackson Mayfly. If you have an Old Town or Ocean Kayak, mounting the transducer is easy, and the cable will pass right through the scupper. On a kayak like the Mayfly, you can DIY a mount or use the YakAttack SwitchBlade transducer arm. The 5-inch screen is large enough to clearly see bottom contour and structure detail, but small enough that it is out of the way. You’ll navigate the menus and adjust settings using the keypad, which isn’t as fast as a touchscreen, but it’s less likely to fail on you. The imaging is pretty basic, but you have to adjust your expectations when going to a budget fish finder. I use this unit just to know how deep the water is, find hard pieces of structure like rocks, and find drop-offs. I don’t rely on it for detecting anything subtle or reliably marking bait. But, for a lot of fishing, those basic functions are all I need. **Read Next**: [How to Read a Fish Finder]() ### Best Under $200: [Garmin Striker 4]() **Key Features** - GPS Enabled - CHIRP Sonar - Waypoint Capable - Temperature Sensor **Pros** - Great Value - Easy Kayak Mounting Options - Low Power Consumption **Cons** - Small Screen Size - No Mapping or Mapping Upgrades ![The author testing the Striker 4]() *The Garmin Striker 4 is an excellent fish finder for the money. Photo by Darren Wendell* The Garmin Striker 4 has been a game-changer for my kayak fishing. The sonar was easy to interpret, and the training-wheel (Garmin Fish Symbol ID) settings helped me get comfortable reading raw data. What stood out most was the ability to monitor my speed—dialing in between 1.75 and 2.2 mph led to more consistent bites from bass and crappie. The water temperature display also proved invaluable, helping me anticipate fish behavior during the spawn. Simply put, it helped me fish smarter, not harder. https://www.youtube.com/watch?v=RHIMoF3ZYVY The depth reading completely transformed my approach. Before, I was limited to bank fishing and guesswork. With CHIRP sonar, I discovered hidden drop-offs and structure holding big fish, including multiple 5 to 6-pound bass. The built-in GPS lets me save these hotspots for future trips. While the small screen and lack of mapping are drawbacks, the Striker 4 delivers where it matters. For an affordable, no-frills fish finder, it’s an excellent investment.

It’s also almost essential for our spring big red drum fishing.” ![Ric Burnley with a big red]() *A big red caught with the help of electronics. Ric Burnley* To use his Helix 7 to find big drum, Burnley will paddle around looking for schools of bull reds on the side imaging. The side imaging shows what’s happening 125 feet on either side of the boat, and it allows anglers to quickly cover water. “You need to become an expert on reading the side scan and what different marks represent. But when those drum show up on there, it’s very obvious,” he said. Burnley owns other fish finders with side scan, but he thinks the Humminbird’s contrast and detail is the best. The Helix 7 doesn’t come with detailed charts, but they are good enough for navigation. You can upgrade the maps if you need detailed charts though. One feature Burnley often uses while searching for drum is the bread crumb feature so he can see where he’s covered and can backtrack to where he last saw fish. Burnley also noted that after several seasons of hard use his Helix 7 is still trouble-free. ### Best for Tournament Angling: [Garmin LiveScope Plus]() https://www.youtube.com/watch?v=pRTmkjNNrWU If you want to [build a tournament-ready fishing kayak](), then you’ll be looking at premium accessories like a Torqeedo motor and LiveScope. Both will help you catch fish more efficiently and step foot on the podium. But, that advantage doesn’t come cheap or without some specialized rigging. Typically, a LiveScope transducer mounts on a boat’s trolling motor, and you can pan the sonar by turning the trolling motor. On a kayak, that’s not easily done. Most anglers using LiveScope or other live sonar will mount the transducer on a rotating arm. In addition to that specialized mount, you might also want to consider having two screens on your kayak—one for LiveScope and one for mapping and side/down imaging. The added electronics, of course, means more power and smarter cable management. But, if you’re willing to put in the time and effort to rig your kayak properly, you’ll have a fish-catching machine. *Read the full [Garmin Echomap and LiveScope review]() to learn more.* ### Best Battery: [Dakota Lithium 12V 10Ah]() The [best fishing kayaks ]()are already heavy, so adding a battery will only add to that weight. To keep your kayak as light as possible, you can use a lithium battery, which is typically half the weight of cheaper lead-acid batteries. The best kayak fish finder battery I’ve used is the Dakota Lithium 12V 10Ah, which gives me plenty of power to run a fish finder all day. After I’m done fishing, I plug it into a charger, and it’s ready to go by the next morning. They are more expensive, around $100, but they're good for 2,000 cycles and carry an 11-year warranty. For efficiency, longevity, and weight, I haven’t found anything that beats the Dakota Lithium batteries. ### Best Battery Box: [Yak-Power Power Pack]() I’m not the handiest person, so when it comes time to rig power, I hit the easy button and buy a Yak-Power Power Pack. You put your battery of choice into the box, attach the cables, and you’re ready to plug in your fish finder. At least that’s how it’s supposed to go, but of course, I needed to do some minor wiring to make it compatible with my battery and fish finder. First, I changed out the battery clips that came installed in the battery box because they were too small for my Dakota Lithium battery. Then I spliced a SAE connector to my fish finder’s power cable. With those two easy modifications out of the way, the battery box was ready to use, and it fits nicely in the front hatch of my Old Town Bigwater PDL. Those two modifications take minutes and is way easier than trying to rig up a battery box with an on/off switch, USB plugs, and power plug. ## How to Choose a Kayak Fish Finder ![Angler poses with fish on kayak.]() *The Tranx 150 can handle big saltwater fish. Kevin Hughes* You can spend a few hundred or a few thousand dollars on a fish finder. The model you choose will depend on your style of fishing. If you enjoy a technique like deep-water jigging for lake trout, a fish finder is a critical piece of gear and you'll want to invest in a quality unit. But, if you spend most of your time fishing saltwater flats, a fish finder is less important and you can get by with a less expensive model. Aside from price range, you'll also want to decide between different transducers, screen sizes, and also consider how easily the electronics will mount to your kayak. ### Transducer https://www.youtube.com/watch?v=LF2uFWSck84 There are three basic types of transducer you can choose from: down imaging, side imaging, and live sonar. Down imaging is the most basic type of transducer and is best for deep water fishing or anglers on a budget A side scan transducer is the most versatile because it will allow you to look at the water below you and the water on either side of you. The side-scan feature is excellent for quickly covering water and most units will cover 100 feet on either side of your kayak. Live sonar is the new craze in fish finders, and many of the [best fish finders]() are now available with some type of live sonar transducer. Live sonar is highly effective, but it does create added challenges for mounting in a kayak and will require an adaptor. ### Size I think a 7-inch or 5-inch display is perfect for a kayak. They’re large enough to see details, but compact enough that they don’t get in the way. ### Mounting Kayak companies have smartly partnered with fish finder companies to make mounting a transducer and fish finder much easier. You might decide to choose a particular manufacturer because their units are most compatible with your kayak. For example, Humminbird fish finders easily mount to Old Town and Ocean Kayaks. Lowrance units mount seamlessly with Hobie kayaks. But, you can mount any of the best kayak fish finders on any fishing kayak with some minor modifications or by using one of the aftermarket traducer arms. ## FAQs ## Final Thoughts For certain types of fishing, a fish finder improves success drastically, and it’s a handy tool for most types of fishing. So, embrace modern technology by choosing the best kayak fish finder for you. - **Best Overall:** [Lowrance Elite FS 7]() - **Best Budget:** [Helix 5 Sonar G2]() - **Best for Saltwater:** [Humminbird Helix 7 CHIRP SI GPS G4]() - **Best for Tournament Angling:** [Garmin LiveScope Plus]() - **Best Battery:** [Dakota Lithium 12V 10Ah]() - **Best Battery Box:** [Yak-Power Power Pack]() ## Author Scott Einsmann is *Outdoor Life’s* gear editor.
