8 Best Fish Finders Reviewed & Tested (Hands-on Guide)

rsz garmin fishfinder featured

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 depth 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.

1. Best Cheap Fish Finder

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.

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.

5. Best Down-Imaging Fish Finder

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.

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 combined 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.

7. Best Fish Finder Under $200

There are some fish finders available for less than $200, but most are very cheaply made and are unlikely to improve your ability to catch fish in a meaningful way.

However, Humminbird – one of the leading manufacturers in the fish finder category – does produce a very powerful, capable fish finder that is priced below $200.

Capable of blasting out sonar signals with 2400 watts of peak-to-peak power, the PiranhaMAX 4 DI is capable of imaging clearly to about 600 feet deep.

It comes with Humminbird’s direct-imaging feature, which provides incredibly detailed images, and Fish ID+, which alleviates the need to interpret arcs – just look for the little fish icons and cast toward them.

The PiranhaMAX 4 DI features a 256 color, 480V X 272H, 4.3-inch display screen and it provides depth alarms, fish alarms, and a zoom function to allow for better viewing. It also provides water temperature data right on the screen.

Important Fish Locator Features to Consider

Man in boat using a depth finder

There are a lot of factors to think about when selecting the right fish finder.

You should consider:

  • the device’s size
  • display type
  • transducer power and frequency
  • viewing type
  • and whether it has a GPS.

Equally as important as the features your fish locators has is its intended use. A fish finder designed for shallow freshwater fishing won’t work well for deep-water maritime environments.

Simply put, you must weigh your needs, preferences, budget, and where you’ll be fishing against the features each depth finder comes equipped with.

To maximize your fish finder, check our guide: Where is My Fish Finder Looking? (Understand Where to Cast)

Here are a few of the most important fish finder features to think about.

Display Specifications

High vs low resolution fish finder
High vs low resolution display fish finder

The display is the heart of a fish finder. It’s where you actually see the data that the device collects. Needless to say, a quality display is important.

1. The first factor to look at is display size. How big of a screen do you need? Most fish finders have between a 4-inch and 12-inch screen. Many popular models are available with different screen sizes depending on your preferences.

Personally, we feel that screen size is the least important display spec. Yet that doesn’t mean you should opt for the smallest available. A larger screen is much easier to use in the field. The larger the screen, the higher the cost, but in our opinion it’s more than well worth it.

2. Next up are pixels (picture elements). The more pixels there are, the better the resolution and quality of the screen. It’s especially important to have a high-pixel display on a device with a split-screen.

A higher pixel rating provides a clearer image, especially of underwater structures. It helps you see fish better, especially individual fish swimming separate from schools and fish swimming along the bottom.

Of course, a higher pixel rating comes with a higher price tag. However, you definitely get what you pay for when it comes to the best screen resolution.

3. The last display related factor to consider is color. A black and white (or greyscale) display gets the job done but doesn’t look nearly as nice as a color display.

Color displays are often easier to read as well. The different colors make subtle differences easier to distinguish than various shades of grey. This makes finding and identifying fish even easier.

Finally, a color display is generally easier to read in both bright sunlight and in the darkness of night.

The thing is, black and white depth finders have effectively pinpointed thousands of fish. Yet anyone that has a color fish finder certainly doesn’t wish it was black and white instead.

Transducer Specifications

Display of the Lowrance DownScan Elite

The transducer is the actual part of the fish finder that sends out the sonar signal to look for fish and map underwater structures. Without a top quality transducer, your fish finder is all but useless.

1. The first factor to look at is transducer power. The power of a fish finder directly relates to how effectively it works. A powerful fish finder allows you to view deeper depths, see more clearly in murky water, and better differentiate between fish and bottom structures.

Fish finder power is calculated in watts RMS (root mean squared). 500 watts is a good base to work from. A 500-watt RMS fish finder will work for almost all applications. In fact, most freshwater fishermen will be fine with a 200-watt RMS fish finder.

2. Frequency is the next factor to take a look at. The higher the frequency, the better the overall detail. A higher frequency fish finder also provides the best view from a moving boat. The downside? You can’t view as deep on a high-frequency fish locator.

Low-frequency fish finders, on the other hand, can penetrate much deeper. The downside is that the images they provide are less detailed.

So what’s the perfect frequency?

200kHZ to 800kHz is perfect for shallow waters while 50kHz to 80kHz is best for deeper waters. Many fish finder models come with multiple frequency transducers for varying conditions.

CHIRP (Compressed High Intensity Radar Pulse), also known as broadband, is changing the fish finder industry. These devices transmit on multiple frequencies at once.

Though they’re by far the most expensive option, they also provide unparalleled resolution and fish detection. CHIRP fish finders give you inch-by-inch details rather than foot-by-foot details.

Viewing Angle 

Low,high, dual frequency fishfinder beam angle comparisonViewing angle also relates to the transducer but it deserves its own category.

There used to be 3 beam angle options when it comes to fish finder:

1. A low-frequency transducer gives you a great view side to side to detect fish around the boat not just under it. This type of fish finder is best for anglers that don’t need a detailed view but benefit from seeing deeper and to the sides.

2. A high frequency transducer allows you to look down with great detail without much of a side view. This type of fish finder is best for anglers needing better fish and bottom separation.

3. And finally, there’s the dual frequency transducer (CHIRP ) that gives you the benefits of both. These fish finders are the most versatile and can spot details and also provide a broad view around the boat.

Side and Down Scan

However, new technologies called side and down imaging or side and down scan have become increasingly popular. Both of these provide you with better viewing angles and greater detail than the previously mentioned solutions.

Learn more about these technologies and their differences in our article: Down-Imaging Vs. Side-Imaging Finally Explained!

Mounting Type

Most fish finders, especially those intended for freshwater use, come with a transducer included. Serious anglers sometimes choose to invest in a separate transducer that better fits their personal needs.

There are a handful of main transducer types as it relates to mounting. These are thru-hull, transom-mount, in-hull, and trolling motor. Each has its own set of pros and cons.

Fishfinder mounted through the hull

Thru-Hull – Best signal quality but difficult to install. Goes right through the hull to the bottom of the boat.

Transom mount in the back of boat

Transom-Mount – Mounted to flat part of the stern of the boat (transom) so it hangs below the hull. Simple to install but is often negatively affected by water flow.

Fishfinder in hull

In-Hull – Glued to inside of hull. Signal penetrates through the hull and doesn’t need direct water contact to work.

Sonar mounted on trolling motor

Trolling Motor – One of the most popular options. Installed, usually permanently, inside the propeller hub of a trolling motor.

Global Positioning System ( GPS )

Most modern fish finders come with a built-in GPS. However, there are still some models that don’t.

A GPS combo fish finder has a lot of benefits. First and foremost, it can help you find your way home if an emergency situation comes up. An example is a sudden and blinding fog.

The other big benefit if the ability to make custom maps. GPS on your fish finder enables you to mark locations. You can drop pins on places you want to fish again as well as places with hazards like stumps or docks.

The only real downside to a GPS combo fish locator is price. Their simply more expensive than their non-GPS counterparts.

The Three Main Options

No matter the specific features you desire, you have three main fish finder options to select from. The choices are standalone, combo, and network fish finders.

  • Standalone – Only a fish finder. Not capable of any other functions. See what’s below you for the cheapest cost. Best for small boats and fishing on small lakes.
  • Combo – Combines a GPS and fish finder. Perfect for mid-sized boats and fishing on open bodies of water. More easily find prime fishing grounds with the help of GPS.
  • Network – Compatible with a wide range of technologies, products, and data sources. Combine your fish finder with radar, video, satellite radio and more. Control with your smartphone. Best for large ships. Network fish finders are constantly being updated each year.

The specific features you need on your fish finder boil down to your individual needs, preferences, and budget.

External Factors to Consider

A number of external factors can affect the best fish finder choice for you. The most important to consider include:

  • boat type/size
  • water depth
  • water conditions
  • saltwater vs freshwater
  • and fish type.

Boat Type/Size

Fishing with sonarThe type of boat you have plays a big role in the best depth finder for you. Namely, the size of your boat and the motor type.

How large is your boat?

Let’s start with boat size first. In the past, smaller boats have required fish finders with smaller transducers. Thru-hull and transom-mount transducers are generally too large for boats smaller than 30 feet. They create enough drag to negatively affect the boat’s handling, stability, and safety.

How often do you use trailer?

Thru-hull and transom-mount transducers also create problems with boats that are regularly trailered. Because these sensitive instruments are placed on the bottom of the boat, trailers can cause damage to them.

That’s where in-hull and trolling motor transducers come into the picture. Neither type of depth finder has a transducer that extends below the hull. This makes them safe to use with small boats (don’t affect handling) and boats that are regularly trailered (nothing to be damaged).

The other rule of thumb regarding boat size is that standalone units work best with small boats, combo GPS units best for mid-sized boats, and network units best for big boats.

Powerful CHIRP units are likewise essential on boats that will be moving at high speeds. Unlike lower-end model fish finders, these can effectively scan and provide data while a boat is moving relatively fast.

Canoes & Kayaks

Fishfinder mounted on kayak

The last thing to keep in mind is that very small boats, such as canoes and kayaks, are best outfitted with very small fish finders. Select a fish finder that works very well in shallow water like marshes, as this is what canoes/kayaks are best for.

However, your canoe/kayak fish finder also needs to be powerful enough to easily differentiate between types of fish. With such a small craft, it’s imperative you know the type of fish you’re located by so you don’t hook one that’s too big.

Finally, it’s always smart to invest in a GPS combo fish finder if your plan is canoe/kayak fishing. Getting lost is even more deadly in these small craft so make sure you can find your way home in a bind.

Saltwater vs Freshwater

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

Deeper smart sonar fish finder

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.

Freshwater anglers benefit more from a low frequency sonar while saltwater anglers benefit more from a high frequency scanner. Of course, an all-around transducer, which includes frequencies, 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

Angler with catch

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 Fish Finder 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.
