Note: If you’re looking for information on the best fish finders in general, check out this page.
Take it from the fish finder experts: there are WAY too many choices out there when it comes to fish finders. Don’t we all wish it was just so much easier to make the right choice? A choice that would continuously net us fish after fish after fish, and give us the least amount of hiccups possible?
It’s not too hard to choose the best fish finder for the money. In fact, here’s a dirty little secet: make the “money” part your deciding factor, and go from there!
Let me explain: If you are having to ask this question, you are probably a recreational angler that wants to catch more fish, right? As easy as that! So first, you need to decide how much you are prepared to spend. You can find a fish finder for less than $100, and you can even find one for $2000!
To make things simpler, we’ve divided up all of our fish finders by budget range, and given you an overview of what you should expect to get out of however much you decide to spend.
Best Fish Finders Reviews – Top Picks
1) Less than $100
For this price range, you are looking at a very basic fish finder that has a small, low-resolution black and white screen and no GPS. This means that the readings you will get will be rather cramped and possible even a little tough to interpret, since color screens generally show better results.
These guys will have a low power rating and a lower end transducer, which means the most depth you will get is about 100-150 feet. The readings will be good, but not fantastic.
I’d recommend a fish finder in this range if you are just starting out as an angler and generally fish really shallow water from a small boat.
Lowrance Hook 3X
The Lowrance Hook 3X contains a backlit LED, 3″, color display, plus a high-performance Broadband sonar with noise rejection, Advanced Signal Processing (ASP), and precise target separation which makes seeing fish easier. It also comes with an onboard temperature sensor, and it can support between 83 and 200 Hz frequencies, which lets you choose the best frequency for your current water conditions.
It has a precise, 320 x 240 resolution so that you can clearly see in the sun, and from wider angles. The Lowrance Hook 3X comes with a Broadband Sounder™ that easily finds fishing targets, bottom hardness and contour, thermoclines, and a lot more. Advanced Signal Processing (ASP) lessens the necessity to adjust settings manually, so you can see what is below you more clearly.
• Basic fish finder, great one to start out with
• Great buy for checking depth
• Very helpful when mounted on trolling motor
• Gives inaccurate depth readings
• Temperature doesn’t always read correctly
• Shows things that aren’t there
2) Between $100 to $300
There’s quite a lot of choice in this range. Thanks to the fish finder scene getting more competitive and technology becoming more and more accessible, your dollar can go really far. The following models really stand out in this price range:
Garmin Striker 4 DV
The all-new, rugged Garmin STRIKER 4 DV fish finder series has a highly sensitive GPS that is created to let you indicate your favorite fishing spots, so that you can find it easily the next day. It also has the CHIRP traditional sonar that displays sharp fish arches along with perfect target separation.
The STRIKER dv series includes CHIRP DownVü scanning sonar, which gives you distinct images of anything below your boat. The STRIKER sv includes both CHIRP DownVü and CHIRP SideVü scanning sonars, so that you can find things on either side of your boat. You can even use a split screen to show both the waypoint map and your sonar option, or even design a customized sonar view at the same time. The STRIKERS series come in 3.5, 5 and 7 inch size displays. It also has a built-in flasher with lets you see your sonar data in a classic flasher format, which is perfect for ice finishing, and for vertical jigging. This garmin fish finder is at a great value for the money.

The Garmin EchoMap 43DV comes with a brand new echoMAP CHIRP dv and sv series chartplotter/sonar combinations. You can purchase these series in display sizes between four and nine inches. The dv series gives you onboard regular CHIRP sonar, plus a CHIRP DownVü. The sv series also offers onboard CHIRP sonar, plus CHIRP DownVü, and CHIRP SideVü scanning sonar abilities. It also has an internal 5 Hz GPS that renews the heading and the position each second five times.
Each of the display sizes for the echoMAP combos can come with either U.S. BlueChart g2 charts, Canada LakeVu HD maps, U.S. LakeVü HD maps, or a basemap that is worldwide. The CHIRP Sonar provides a continuous sweep of frequencies that range from high to low, and it interprets the each of the frequencies individually when they return. It also includes new software like the new Garmin Quickdraw Contours that allows users to make their own maps that include up to 1-foot contour lines, anywhere you want.

Also, for between $100 to $300, there are a couple of really cool smartphone fish finders. These are devices that can mount to your boat or attach to your line, which you cast and the device will send the SONAR returns to your smartphone screen via an app(iOS and Android). They have great battery life, and capitalize on your smartphone’s capabilities – so while they’ll work even if you don’t have a data connection, if you do, you’ll see loads of real-time info, too. Check them out – our favorites are the Deeper and Vexilar SP200.
Deeper Smart Portable Fish Finder
The Deeper Smart Fishfinder 3.0 is an echo sounder that is wireless and castable. You can use it easily in any spot as it just floats on top of the surface, and then sends all the information from the bottom and the water column to your smartphone or tablet.

It works up to 130 feet with a secure Bluetooth connection, so it is ideal for short distance casting like ice or canal fishing.
The Deeper app is easy to download and use. When used with the device, it creates a complete piece of underwater sonar technology. It is compatible with most iOS and Android devices. You also do not need a Wi-Fi internet connection, or need to use any mobile data since the Deeper device only uses its internal Bluetooth access point that easily links to your phone or tablet.

3) Between $300 to $600
This price range is the “premium” that combines all the best technology into small packages. If you have the budget, I highly recommend that you find a model from this price range. Generally, these models will all have color screens, usually 5 inches, a high power rating(for more depth), internal GPS with decent maps(and the ability to expand), and some models will also have Down Imaging/DownScan SONAR. With all of these models, you are looking at depths of at least 500 feet.
Some of my favorites:

It comes with CHIRP sonar, and has the ability of today’s foremost Fishfinder technology that can easily find anything under your boat.

4) $600 and above
At this price range, you will be paying for all of the features of the group before this one, and two more critical ones: screen size and expandability.
From here on, you are looking at really professional level models like the Lowrance HDS series and the Humminbird 700/800/900/1000 series, all of which have very powerful SONAR, high-definition screens, powerful mapping packages, and the ability to add more peripherals like radars, weather, satellite radio, and the ability to network 2 or more units together.
Something in this range is good for you if you are a professional(or aspiring professional) that wants something that can help monitor everything on your boat from SONAR to navigation to even monitoring fuel levels in your motor/engine.
Tournament anglers and professional charters all use units that are in this range. At $600-700, you will get a basic model, and as you go more expensive, you are looking at larger and larger screens with more advanced peripherals.

Best fish finder GPS combo under $500
The Humminbird Helix 5 SI CHIRP fish finder has to be one of the most powerful fish finder gps combos that you can buy for just under $500.
It has super accurate CHIRP SONAR, as well as side imaging SONAR, and includes a fully featured chartplotter that is compatible with a whole host of different mapping packages such as Navionics and Humminbird LakeMaster, to name a few.
In addition, this fish finder will let you see up to 1500 feet(on a good day in fresh water) using the traditional SONAR, and up to 240 feet on either side of your boat with Side Scan SONAR.
The real advantage of Side Scan SONAR is that you can map out an entire area of water with a single pass and immediately identify good areas of structure and cover, as well as find schools of baitfish!
The GPS functionality of this fish finder is also very good: you can store up to 2,500 waypoints, 45 routes, 50 tracks, and 20,000 track points – which is more than enough, really – who is going to need 2,500 waypoints anyway!
You can also use the Side Scan SONAR to overlay contours and depth data on to the map itself, effectively creating your own customized maps.
Best fish finder GPS combo under $1000
There are actually quite a few great choices for a fish finder GPS combo under $1000 – once we’ve got so much flexibility in our budget, it becomes a little harder to narrow down choices. However, we’ve picked three that really caught our eye(and helped us catch fish!) – and each one has their own one important feature which may help you decide which way to go.
Budget – Simrad GO7 XSE
The Simrad GO7 XSE is well below our budget cap of $1000, but still sports a high resolution 7 inch display, an excellent mapping package(waypoints and tracks are all default options on gps fish finders, anyhow), as well as CHIRP SONAR, Down Scan, and Side Scanning SONAR.
The GO7 is also fully expandable using NMEA 2000, so you can hook up your audio system, your motor for fuel and monitoring, and effectively turn this unit into the control system for your boat. If you have a more complex boat setup that you’d like to manage from a single interface, then you really can’t go wrong with this fish finder.
Largest screen size – Humminbird Helix 9 DI
The Humminbird Helix 9 DI is much like the Humminbird Helix 7 we saw above, except on steroids! It can do everything the Helix 7 can do(though this model only supports Down Imaging with the default transducer) – plus a whole lot more. The larger screen models are meant to become control centers for your boat, so you can hook up other components on your boat using NMEA 2000 and manage them all from one screen.
You can even hook up your phone with Bluetooth and see missed calls and text messages! Though honestly, when you’re out fishing, you don’t want to be bothered with phone calls!
The mapping packages and charting options are solid, plus expandable using the memory card slot, so you can use any mapping package of your choice. Navionics+ has highly detailed charts, and is the chart of preference for many anglers – which you can use with the Helix 9 DI.
Finally, because Humminbird and Minn Kota have the same parent company, many Humminbird models integrate with Minn Kota motors – so if you have a Minn Kota motor that has their iPilot GPS, you can hook it up to the Humminbird Helix 9 and effective set courses on the screen and have your motor get you there!
Screen size is incredibly important! Even though the difference may seem like one or two inches, since it’s measured diagonally, the overall size is drastically different. To get an idea of how big fish finder screens are, check out our fish finder screen size comparison.
