A fish finder is a very useful tool that, as its name implies, helps you locate fish underwater. It uses pulses of sound energy (sonar) to create a graphic display of the underwater landscape. The monitor displays fish, ground structures, and debris.

The popularity of fish locators among sport and commercial fishermen has led to a boom in the number of products available. But not all sonars are created equal.

It’s imperative that you select the right model for your needs and preferences as well as the specific conditions you’ll be fishing in. The wrong fish finder isn’t just ineffective, it’s also often unusable.

That’s where our ultimate fish finder buyer’s guide comes into the picture. We break down the most important features (including display, transmitting power, frequencies, and GPS) and provide detailed reviews of the top brands and models

Garmin Striker 4 – Full review

garmin-striker-4

The Garmin Striker 4 is the perfect choice for those who don’t want to spend an arm and a leg on a fish finder. Since it is relatively low priced, it’s not as powerful as other models yet it still gets the job done.

It comes with a 3.5” display and up to 1,600 feet freshwater depth performance. The color screen, CHIRP system clarity and backlight make it easy to read the device even in direct sunlight.

The small, rugged design is its highlight. It perfectly fits on a small craft such as a canoe or kayak and is portable.

The transmitter sends signals on multiple frequencies ranging from mid to high 50/77/200 kHz and with 200W sonar power, it’s more than powerful enough for most freshwater lakes.

Garmin made the Striker 4 really easy to use as possible. The display shows very crisp fish arches that make target separation a breeze.

The GPS, which is a great surprise considering the price tag, makes it very convenient to save your best fishing spots or check your trolling speed.

 

 

Best Value for Your Money

Garmin Echo 551dv

garmin-echo-551

Who doesn’t want the best bang for their buck? If a favorable cost-to-benefit ratio is your primary criteria, the Garmin Echo 551dv is for you.

It packs a number of useful features into a compact body. Highlights include the bright and crisp VGA color monitor that’s easy to read in any weather conditions.

The screen’s resolution is so good that the underwater details appear nearly photographic. Move from place to place, and the display seamlessly transitions from different depths.

One of the best features of the Echo 551dv is its transducer. With a 20-foot long cable, it’s pretty long to use on good-sized boats. The narrow-to-wide viewing cone lets you see into the water well beyond the sides of your boat.

It works for depths up to 2,300 feet. It is fully adjustable so it works just as well in very shallow water as it does in very deep water. Sonar history rewind allows you to scan back to an area that you already passed over.

 

 

Best GPS Combo

Raymarine Dragonfly 7 Pro – Full review

raymarine dragonfly fishfinder

The Raymarine Dragonfly 7 Pro is an excellent choice for those that want a fish finder with a GPS.

Though a GPS combo fish finder is more expensive upfront, it’s a great investment and more than pays for itself in the long run. The biggest benefits are the ability to create your maps on uncharted bodies of water and get home safely in an emergency situation.

In addition to its built-in GPS (with Navionics charts), it comes with Spectrum CHIRP Technology. This powerful form of sonar allows a more precise detailing of underwater image structure. It even allows the transmitter to pick up more fish.

Its 7-inch high-definition LCD monitor is equally impressive. It’s easily viewable in all weather conditions and provides an incredibly clear, near photographic, representation of underwater structures. The device works to depths of up to 600 feet.

The Dragonfly 7 Pro is extremely durable and can hold up to intense abuse. Optical bonding ensures the LCD screen never fogs up in all weather conditions. A transducer and mounting template are included and are easy to install.

 

 

Best Side-Imaging

Garmin Striker 7SV

A side-imaging fish finder allows you to see much more to the sides of your boat than a traditional fish finder. The Garmin Striker 7SV is an excellent choice for a side-imaging model.

It is notable for its rugged design. It’s built to last for years on end, withstanding the harsh marine fishing environment in the process. The 7-inch color LCD monitor never loses its luster.

CHIRP sonar sends a continuous sweep of sound energy in different frequencies for the most accurate mapping possible. It comes with both down-view and side-view for more accuracy.

Another notable feature is the built-in GPS. The high-sensitivity unit means you always know exactly where you are.

You’re able to drop pins to mark great fishing spots for later use. You can also drop pins to mark hazards such as stumps and docks. Another essential benefit of the included GPS is always knowing exactly what speed your craft is moving at.

Everything needed to effectively use the device is included. You get the fish finder, transducer and mounting template. The device is easy to install and set up, it’s even easier to use it in action.

 

 

Best Down-Imaging

Lowrance Elite-7x

A down-imaging fish finder is one step above a traditional sonar. Not only does it show you the location of the fish, but it also provides a detailed image of it.

You have a lot of options with down-imaging fish finders. However, one of our favorites is the Lowrance Elite-7x. It is very powerful and useful considering its price tag.

The Elite-7x comes with a bright and colorful 7-inch LCD screen. The split-screen provides very explicit images of bottom structures and fish. The monitor is easy to use in any weather condition, including bright sunlight and during the night.

It is best used in relatively shallow waters where schools of fish congregate. It also comes with a high-quality GPS for the best in precision navigation. Mark fishing spots and danger areas with the GPS.

The device comes with an 83/200KHz transducer.  It’s easy to install and even simpler to use. This is a simple yet dynamic down-imaging fish finder in every sense.

Best High-End

Lowrance HDS-7 Gen 3

lowrance-hd-7-gen-3-fishfinder

For those fishermen that always demand the best of the best, there are no better options than the Lowrance HDS-7 Gen 3 fish finder.

It combines all of the best features of the fish finders outlined above. Its 7-inch, multi-touch LED screen is intuitive to navigate and use. The fast processor and scrolling features allow you to make real-time adjustments on the fly.

The fish finder technology employed by the HDS-7 Gen 3 is the best out there. It enables you to view both CHIRP sonar as well as HD StructureScan at the same time.

Side-imaging and down-imaging give you the best overall view of structures and fish underneath your boat.

It has both a GPS and Wi-Fi connectivity. Information can be stored in the cloud so you can create and share your maps. it is also compatible with other technologies like SirusXM Marine Weather, SmartSteer control for MotorGuide Pinpoint GPS, and Broadband Radar among others.

In short, the HDS-7 Gen 3 is one of the smoothest, most accurate fish finders on the market today. You can even view two charts at once for total control. Sure, it costs a pretty penny but it’s worth every penny in the long run if you are a serious marine fisher.

Saltwater vs Freshwater

Consider the type of water you’ll be fishing in: saltwater or freshwater.

Saltwater is a more challenging environment than freshwater. In addition to the salt and other debris, the sheer amount of living organisms often throws fish finders off.

If you’re fishing in saltwater, we suggest investing in the quality. CHIRP models do a much better job at working through the debris than traditional models especially in deep waters. Look for a fish finder specifically designed for saltwater as well.

Freshwater, on the other hand, isn’t as much of a challenge for fish finders. The only piece of advice to keep in mind here is to look for one with a higher frequency for shallower waters. CHIRP models can be useful for those primarily searching in very shallow, silt-heavy waters.

Freshwater anglers benefit more from side scan sonar while saltwater anglers benefit more from a down-looking scanner. Of course, an all-around transducer, which includes side and down imaging, works perfectly for either.

Remember that many fish finders come with a variety of settings. Some even allow you to select between a saltwater and a freshwater setting. This models are ideal if you plan to use the same boat in both environments.

 

Water Conditions

You have to consider the water’s depth. As we’ve discussed a few times already, different fish finders work better in different depths.

  • Fishing in shallow water requires a high-frequency fish finder.
  • Fishing in deep waters requires a low-frequency fish finder.
  • A model that uses dual frequencies is ideal for those who plan to fish in both types of water.

 

Type of Fish

What kind of fish do you plan on catching?

Of course, fish type once again relates to factors like depth and saltwater/freshwater. Find a unit that works best at the depth where the fish you’re after are usually located. Here are the essential points worth remembering:

  • A powerful fish finder is much better in identifying individual fish.
  • Cheaper models tend to only locate schools of fish or vaguely identify individual species.
  • Different species of fish also show up better or worse on different scanners due to their frequency ranges. Higher frequencies, in particular, are best at spotting isolated fish as well as smaller species.

Once again, a CHIRP fish finder is the best choice if you can afford it. They work well in all conditions and for all types of fish — both individual and school.

 

Pros and Cons of Top Brands

Several fish finder companies stand head and shoulders above the rest. These brands are the most popular and time-tested out there.

Each is known to cater to a particular area of the market. Searching for the best fish finder by brand is often helpful. Here are the top four fish finder companies in operation today with the pros and cons of their products.

 

Garmin

Renowned for their contribution to automotive, aviation, maritime, and outdoor GPS technologies, it comes as no surprise that Garmin is the most powerful name in the fish finder world.

History

The company was established in 1989 and has since grown into one of the world’s leading specialists in GPS development. As you might suspect, most of their fish finders come equipped with this GPS.

Garmin has that area of the market cornered. Their GPS combo fish finders are undoubtedly the best. They’ve fine-tuned their mapping applications to make marking and finding the best fishing spots as intuitive as possible.

Company’s Focus

Something that stands out about Garmin is the durability of their products. All of their fish finders are, as their company motto states, “built to last”. A fish finder needs to stand up to extreme wear and tear as well as severe weather conditions – their units do this and more.

Popular Series

garmin striker series fishfindersGarmin has several fish finders in its lineup, but none are as popular as the Striker. Available in different screen sizes, each Striker is equipped with GPS and CHIRP sonar.

Though the Striker comes with an included transducer, Garmin also produces a wide array of aftermarket sensors. These are perfect for those fishermen using their fish finders for specialized applications.

Overall

Strengths 

  • overall durability
  • highly-sensitive GPS
  • CHIRP sonar
  • transducer versatility

Downside

  • high price
  • Lack of data entry capability. You can’t enter data saved on another device to your Garmin fish finder.

Best For

  • Serious fishers will greatly appreciate their high-quality fish finders.
  • The CHIRP sonar is perfect for those fishing in variable conditions where great precision is required.

Simply put, the high price tag for a Garmin fish finder scares away all but the most serious anglers.

 

Lowrance

Lowrance

Lowrance has a stellar reputation as a reliable manufacturer of GPS, sonar, and digital mapping systems, specifically for maritime applications. Their expertise with such technologies is apparent in the quality of their fish finders.

History

The company was founded in 1957. Ever since its very beginnings, it’s been dedicated to fishing. The founder, Carl Lowrance, created the company after noticing that most fish are found in schools and specific areas.

Lowrance and his sons set about creating a device to make it easy for fishermen to locate these fish-heavy locations. The result was a lightweight, compact, and portable precursor to modern fish finders. It was the first instrument to use sonar technology for sport fishing.

The company’s history in the creation is still evident to this day. Their fish finders are among the most effective around. It’s apparent all those years of experience have paid off.

It’s hard to say that any aspect of the company is more impressive than its history. Lowrance is simply the most trusted name in the fish finder industry.

Company’s Focus

Lowrance doesn’t exactly cater to a specific area of the fish finder market, although their deep water fish finders are their most popular.

These devices employ their award-winning Broadband Sounder technology, as well as DownScan imaging, making it easy to find the fish you’re looking for.

Popular Series

lowrance elite 9x fishfinderThe Elite-9x CHIRP is Lowrance’s most impressive model. It combines a 9-inch screen with CHIRP sonar, DownScan Imaging, and a variety of options for transducers.

Advanced Signal Processing adjusts the image you see automatically, reducing the need for manual adjustments. The Elite-9x CHIRP is fully equipped with GPS technology.

Overall

Strengths

  • DownScan Imaging
  • CHIRP sonar
  • multitude of settings options
  • vast selection of models

Downside

  • Their fish finders are notoriously difficult to learn, yet everything will click before long.

Best For

  • Serious fishermen who don’t want to dish out a crazy amount of money. They’re solid devices at reasonable prices.

 

Humminbird

Humminbird

Humminbird is unique among companies on this list because they focus solely on fish finders. They don’t produce any other products.

Their specific dedication to fish finders allowed them to create some of the best models available. It also translates into the most extensive selection. They have a model that suits just about any angler’s needs and preferences.

History

The company was founded in 1971. Since day one, their goal is to create the best fish finders on the market.

Though their current offerings are a far cry from those products from the old days, they still have that classic Humminbird dedication to quality and attention to detail.

Company’s Focus

Like Lowrance, Humminbird doesn’t attempt to target a specific part of the market. Instead, they produce a wide variety of fish finders for different uses. They have units for:

  • big boats and small boats
  • freshwater and saltwater
  • shallow water and deep water

The options are endless. It’s this diversity of products that helps Humminbird stand out. No matter what you’re looking for, the company has a fish finder that’s perfect for you.

Case in point is their ICE series. Unlike most fish finders that are designed to be used on boats in open water, these are specifically designed for ice fishing.

The ICE series instantly gives you the exact depth you’re fishing at and pinpoints any fish beneath you. The built-in GPS helps you pinpoint hot spots so you can return to them later.

Popular Series

humminbird helix series

While the ICE series is arguably Humminbird’s unique product, it’s not their most popular. That honor lies with their Helix series.

Available in screen sizes ranging from 5 inches to 12 inches, these fish finders combine broadband CHIRP sonar with some of the most impressive mapmaking software we’ve seen.

Another highlight of the Helix series is its display. It’s one of the brightest and clearest we’ve seen. The interface is also high among the most intuitive and easy to learn to use.

Overall

The high points of the Helix and ICE fish finders translate to all other Humminbird products.

Strengths

  • robust, durable construction of their devices
  • vast selection that suits every angler’s needs
  • their dedication to fishing

Downside

  • Slow processing. The data they provide is great but it often takes a long time for it to appear on screen.

Company’s Focus

Raymarine focuses on the high-end market. The bulk of their fish finders are undoubtedly high-end with high price tags to match. Though they do have more basic options available, these simple fish finders are not what they’re known for.

In fact, Raymarine is known for the impeccable quality of its products. All of their fish finders (as well as their other marine electronics) are known for their ease of use, durable design, and overall reliability. They are simply designed to last for the long haul.

His favorite fishing locations are in northern-europe, although he is not entirely sure is this because of fish or just the untouched, raw nature.

Favorite species are pike and surprisingly – perch, apparently these small fish just taste that good.
