Best Overall: Garmin ECHOMAP UHD2

Why I Love It

Garmin’s ECHOMAP UHD2 really stood out to me, mostly because of the vast improvements over the original UHD series. This thing becomes a veritable nightmare for fish when you pair it with the Panoptix LiveScope, but the GT56 transducer is a fantastic transducer all the same. 

One of the biggest decisions Garmin made was to improve the resolution on the larger UHD2 models, upgrading from the 800 x 600 resolution of the previous generation. 

While 1024 x 600 isn’t mind-blowing on paper, I think it looks fantastic, especially paired with Garmin’s sun-viewable tech. 

Little fish and big fish are easy to separate, and the level of detail is incredible. For the chartplotter fanatics out there, the GPS receiver jumps from a 5Hz frequency to 10Hz. While it’s more of a drain on your battery, the response is far more rapid and instantaneous in some cases. 

Garmin has always focused on a key interface, rather than a touchscreen, but the combination of both is one of the smarter business decisions they could have made. 

I like how responsive the touchscreen is, but I still enjoy the key interface for precision when needed. 

Traditional CHIRP sonar, SideVü, and ClearVü are all here, and one of the first things I noticed was that Garmin wasn’t exaggerating about the 20% extended range with SideVü. 

The amount you can broaden or narrow the cone is excellent, with 260, 455, 800, 1000, and 1200 kHz frequencies. This range opens up a lot of options with broader cones in shallow water and narrower precision cones in deeper water. 

The same frequencies are available for ClearVü (Garmin’s version of down imaging). One of the more anticipated elements of the UHD2 release was Garmin’s upgrade to Navionics+, and I was highly impressed with the improvements. 

I was thoroughly impressed with the Garmin ECHOMAP UHD2. If you’re looking for impressive and accurate side imaging (with the GT56, 54, or even the GT20 transducer), ECHOMAP UHD2 is easily one of the best.

Best for Kayaks: Lowrance Elite FS 7 Active Imaging

Why I Love It

The Lowrance Elite FS 7 is a fantastic fish finder for kayaks. It’s just the right size for easy mounting options, and shallow water fishing takes full advantage of the FS 7’s SideScan and fantastic imaging. It’s also perfect for smaller bass boats and jon boats as well. 

Lowrance put together a very accurate fish finder, and its compatibility with Active Imaging is impressive. 

The Active Imaging 3-in-1 takes full advantage of the Elite FS 7’s visual capabilities, along with great range, Fish Reveal Smart Target (targets and identifies fish), multiple angle viewing, reduced noise level, and specific depth isolation. 

You also get DownScan and automated “Scout” views in real time. The FS Elite is small enough to suit a large fishing kayak, but I had some trouble getting everything set up—something which Lowrance is known for with this particular model.

The Active Imaging transducer truly shines in shallow water thanks to incredibly fast ping speed, which results in highly detailed images. 

The faster the ping, the more detailed and richer the feedback. Since the Elite FS 7 features Lowrance’s SolarMAX HD screens, you won’t miss any of that detail, even in full sunlight and from extreme angles. 

If you’ve ever experienced a Lowrance fish finder before, you know excellent screens are one of the company’s strong suits. Sitting on a kayak, staring at a 7″ screen, backlit at 1,200 nits, you will see everything from your own, tiny lure to baitfish, large fish, and structure detail that’s nearly picture-like in quality. 

Another thing I love about the Elite FS is the SideScan plus map overlay, otherwise known as StructureScan. 

Anglers can take their on-screen maps and overlay them with SideScan. This puts everything into perspective and significantly boosts mapping capabilities on the fly. 

Lastly, when it comes to networking, the Elite FS has it all. Bluetooth, Ethernet connection, Wi-Fi, and NMEA 2000 are all present and accounted for. The level of customization and automation is fantastic. 

During my field test of the Elite FS, I said: “If you fish tournaments, this is definitely a unit to look into.”

If you spend a lot of time fishing from a kayak, the Lowrance Elite FS is a top-of-the-line model for your craft. It’s a little on the large side, but it feels perfect when you get it set up. It’s also a great choice for jon boats and small bass boats. It’s well-priced on Amazon, but you can find lower prices on Cabela’s and Bass Pro Shops.

Most Budget-Friendly: Garmin Striker Vivid 7sv

Why I Love It

The Garmin Striker Vivid 7sv packs a lot of hardware and software into a device that carries a sub-$500 price point. I understand that fishing can be an expensive hobby, and I practically ooze envy whenever one of the big three releases something new that would require me to sell a kidney on the black market to afford it. If you’re like me, you want the best sonar on a budget. 

It was hard not to like the Vivid 7sv. The upgraded GT52HW-TM transducer offers outstanding detail, better than other sonar, even at higher price points. The way Garmin combines waypoint plotting with exceptionally fast GPS is mind-numbing. 

It features a lively color display that you can split into four screens and enough hardware under the hood to watch it all without a hitch. It’s rare to see traditional CHIRP sonar, down imaging, and side imaging sonar at a price below $500, especially with built-in contouring and Wi-Fi connectivity. 

Bright sunlight has little to no effect on screen visibility. Side and down scans show up in a variety of vivid colors, or you can set the color schemes you want. Either way, the level of detail isn’t lost, regardless of outside conditions. 

The only real complaint I could come up with was Garmin’s decision not to include preloaded maps or a slot for a microSD or standard SD. You can make your own maps all day long with contour mapping, but you’re limited to onboard storage. 

Like the Lowrance Elite FS 7, the Vivid 7sv is a good option for large kayaks, jon boats, and small bass boats. But it’s also just as good on larger craft as well. If you want to take advantage of some of the best advances in sonar tech—without breaking the bank—Garmin’s Vivid 7sv is the answer.

Best Premium: Humminbird Solix 12 CHIRP Mega SI+ G3

Why I Love It

We were already impressed with the Humminbird Helix series fish finders, and Humminbird simply took what worked and made it better in every way. Yes, it’s on the pricey side, but what we love about it is the fact that it’s a monster in every category.

Professional angler, Carl Jocumsen broke down the Humminbird Solix in a couple of sentences:

“This is the greatest setup that I’ve ever had in my career. It was 100% the reason I was able to break that lake down in 10 days.”

The Mega down and side imaging technology are incredible, thanks to the transducer, with the optional XM 14 HW MSI T transducer standing head and shoulders above the rest. We found that the imaging returns on the Solix 12 are probably the best on the market today. A lot of that is because the Solix can get into the MHz range, offering 250′ on either side of the boat and 250′ down. 

My personal favorite is the level of customization. You can change the color palettes and tweak the imagery to your heart’s content. 

As sonar technology goes, the Solix is just hard to beat. Not bad for something that’s been out for several years now. One of our Anglers.com team members, editor Coty Perry, recently wrote a review on the Solix and said, “MEGA Side Imaging gives you an unparalleled view of the underwater terrain.”

The mapping is fantastic, and the Solix comes with the Humminbird Basemap onboard, as well as compatibility with Navionics, LakeMaster, and CoastMaster. Its chartplotter capabilities are also second to none. 

Other than the price, one of the other drawbacks to the Humminbird Solix 12 is that it only comes with Basemap. Basemap is perfectly fine unless you live in Canada, and it’s more of a minor gripe at the end of the day.

Traditional sonar has been outdated for a while, and the Solix 12 effectively renders it obsolete. It’s not for everyone, thanks to its steep price point and complexity. However, if you’re looking to step up your game to the amateur and professional tournament levels, there’s no better place to start.

How I Selected My Favorites

Yes, I spend a lot of my time typing words about some of the best fishing products on the market today. However, I’m also out there on the water, fishing and using these fish finders to find out what works because I know it will work for you too. Anglers.com testing parameters are included below:

• Transducer: The transducer is the second half of the fish finder, so what side-imaging quality does it produce? Is it accurate? Detailed? Precise? Durable and dependable?
• Mounting: It’s amazing how so simple a feature can be so critical. How well does it mount? Does it hold up over time? Is it convenient, and what degree of portability is there?
• Screen size: This is another crucial component because the larger the screen, the higher the pixel count needs to be for a sharp and decipherable resolution. Does it feature a split screen? If so, to what degree? Is it best for a kayak or a bass boat?
• Power, frequency, and range: The three are inextricably linked. High frequency for shallows and lower frequency for depth. Plus, how much strain will the fish finder’s capabilities place on your battery, and how far can it reach out?
• Mapping: Side imaging is as much a scouting and mapping system as it is a fish-finding technology. GPS is integral to side imaging both for navigational purposes and high-quality mapping.

Side Imaging Fish Finder Buying Guide

Whether you like to buy from Amazon, Cabela’s, Bass Pro, or any other online or in-person fishing retailer, you have to know what fish finder you’re looking for. This is especially true for new anglers. 

First, you have to know what your needs are. There’s no sense in refinancing your home to get a Humminbird Solix 12 when all you need is a Helix 7. 

• Display specs
• Amount of power
• Transducer size for your craft
• Frequency
• Screen size
• Combo or single fish finder

These are all things you have to carefully consider. For instance, a 10″ screen may give you trouble on a kayak. A large transducer might be too much for a smaller craft. Your power needs are important as well. 

Some of the fish finders on our list have extensive output, which can sink your battery in a hurry if you aren’t prepared. If you own a large boat, you may consider a combo pack, with perhaps two Humminbird Helix 7s, or ECHOMAP UHDs—one for the bow and one at the stern. 

If you decide on a combo, networking comes into play. Garmin’s UHD2s pair nicely with each other wirelessly, but they don’t pair with other Garmin devices or other brands. Do you fish in the sun a lot? Make sure the screen is designed for sunlight readability. 

Final Thoughts

The best fish finder with side imaging is the Garmin ECHOMAP UHD2. It’s an exceptional piece of sonar hardware that won’t break the bank. If you want to upgrade in the future, it’s completely compatible with LiveScope and, on its own, it offers incredible side imaging. 

Garmin also makes the Vivid 7sv if the UHD2 is too rich for your blood. The Vivid 7sv is an outstanding fish finder, featuring side imaging sonar and many of the bells and whistles found in pricier units, all for a price point of around $500.
