10 Best Fish Finder for the money in 2022

Have you been struggling with catching fish lately? If so, you might need a fish finder.

Fishes are known to be experts at hiding themselves from other anglers, and your current equipment might not be enough to track them.

However, a fish finder can do that for you!

For example, if you’d try to look into the water to see your target, you’d only see a murky lake around you. You can’t tell where your target is or where to look for it. This is where a fish finder comes to play.

It’s a unit that locates and tracks fish in whatever location you are. It can scan the waves and show you exactly where the fish is. Some can even tell the water temperature and depth of individual spots.

There are many different models on the market, and while most offer the same essential things, they are somewhat different. Fish finders can have a few other useful features depending on the model.

Maybe you’ve heard of such device, but you aren’t sure you know enough about it. We’ve done some research on your behalf to bring you the best and inexpensive fish finders.

These are the best on the market, and we’ll discuss all their features.

1. Garmin Striker 4 with Built-in GPS

Best Overall

Standout Features:

Garmin is one of the best brands when it comes to the navigation system. Thanks to its built-in GPS, it allows you to mark all the hot spots so you can return to them with ease. Regardless of whether it’s a river or open water, this is one of the best ones to track your progress with.

It has a relatively small screen of 3.5’’, but it also comes in 5 and 7 inches. It’s a full-color display that has high contrast. It allows you to see everything in a crisp and clear image.

However, it doesn’t have a split screen option, so you’ll have to switch in between menus. Though this isn’t a significant setback, it might be a reason for you to opt for the one with a bigger screen.

It offers CHIRP technology providing 200-watt RMS signal. This allows you to reach down to 1600ft. in freshwater and 750ft. in salt water.

If you’re on a kayak, the GPS isn’t that much of a necessity because there’s a high chance you’re not going to go that far off the radar. But, if you’re on a boat, then having a Garmin Striker 4 with a built-in GPS is something you’ll definitely want.

A lot of consumers have questioned about the battery life of the Garmin Striker 4, and understandably so. It lasts up to 16 hours which is really good, but there are a few things you can do to conserve battery life. For example, turn off the backlight when you don’t need it.

We found the chirp sweep sonar to be really helpful when looking for fish and the included transducer performed well. We could see the bottom very clearly and even mark waypoints on it with great accuracy. The GPS was also very responsive, locking onto our position quickly and maintaining a signal even in more open water. Overall, we were very pleased with the Garmin Striker 4 with Built-in GPS and would recommend it to anyone looking for an affordable fish finder.

7. Lowrance HDS-9 Gen2 Touch Insight Display

Standout Features:

Its charting technology is super advanced, which is why this isn’t the most affordable option. However, it’s top-quality which justifies the price.

How To Pick The Right Fish Finder

Choosing only one out of so many is sometimes a little tricky. More so, the search can become overwhelming if you’ve never had one before.

There are many important things to consider before you opt for a specific model. To make things easier for you, we’ve created this list of things that could help you on your quest.

Frequency Range

Frequency is one of the most important things to pay attention to. There are dual, single and multiple, and they come in 50, 83, 192 or 200 kHz.

High frequencies are best for shallow water, while lower ones are best for deep water fishing. However, higher frequencies show more detail on the screen.

To make the decision, decide on the area you’ll use it in most often. Knowing whether you’d be in shallow or deep water helps you determine which unit offers the best options.


When looking at how the fish finder is powered, pay attention to its wattage. More wattage means better response time. Also, units with more wattage allow you to see deeper into the water.

Again, it’s best if you’d know what areas you’d use it in because that will help you decide on wattage you need. Rule of the thumb is that shallow water needs less wattage since it offers better visibility.

Combine wattage with the frequency range. Remember that at 50 kHz with every 100 watts, you can go as deep as 400 ft. under. At 240 kHz and 100 watts of power, you can read at 100 ft.

Display Resolution

The higher resolution, the better. Choose the one that has at least 240 x 160 pixels, but no less. This is too little for most people, but it’s a good starting point.

Better resolution means more explicit images and more detail. Plus, a large screen combined with high resolution offers ultimate experience.

Opt for more resolution and bigger screen size for your fish finder if you want more detailed pictures. In any case, choose according to your preference.


The transducer is what does all the major work. It’s what emits and receives sonar waves and discovers the fish and objects. Ultimately, without this, the fish finder wouldn’t be able to show any data whatsoever.

However, many fish finders come with a transducer, but they aren’t all the best quality. Sometimes, it’s best if you buy one separately.

The after-market transducers often receive data faster and cover areas better. Again, choose according to your preference. If you have a transducer that works well for you, there’s no need to buy another. If you find that it’s missing something, try a different one.

Side Imaging fish finders for example, comes with a special type of transcuder; typically mounted outside of a boat’s transom.


Things like transducer material, beams and cone angles are also important. Look for a unit that’s waterproof and easy to use in sunlight and nighttime.

It’s also good to consider a convenient and portable unit that you can use in multiple boats.

How To Utilize Your Fish Finder

Read The Manual

The instruction manual is often forgotten though it can provide much useful information. There’s no better way to understand your device than to check out the user manual that came with it.

You’ll find out how to use and read it correctly. It’s well-known that this isn’t anyone’s favorite part, but it can help you get the most of your fish finder.


The fish finder should be in the best spot if you want best results. However, there are a few different mounts available.

Transom, hull, trolling or portable are the few most popular options. Still, there’s no way to tell which would be the best, since it’s something you should decide on based on your needs and preferences.


When turned on, the fish finder is usually set in automatic mode. Pre-program settings are also on when you start.

If you want to customize it, switch to a manual mode. It’s recommended you leave it in the automatic mode for a while. When you get on the water, use the automatic mode to see what’s around first before you switch to manual.

Adjusting Settings

Sensitivity is the first thing you should learn your way with. It’s what improves the power and with that, allows you to see more detail.

With lower power, the image quality is also lower. The best way to learn how to manage this is to play around with it for a while. You’ll find the settings that suit you the best quickly.

Adjusting Fish ID

If your device is on the automatic setting, it’s going to identify fish automatically. This is great for beginners and people trying to learn how the fish finder works. Once it’s adjusted, the Fish ID can be turned off.

This feature tells you what’s under the waves, giving you a better view of the water beneath you.

Auto Depth

Auto depth should always be on if it’s your first time using sonar. This feature tracks the water floor, telling you how deep it is.

You’ll be able to adjust this setting as you gain more experience.

Depth Cursor

This line goes across the screen and shows how far down are the fish. This is ideal to help you decide where to cast your bait. It makes fish finding easy since it moves up and down the screen.


This is usually an automatic setting, but you can adjust it to your taste whenever you want. It blocks out all the background noise you’ll sometimes experience. However, it can also block out sonar, so make sure it’s not always on.

Advantages Of Using A Fish Finder

Apart from the obvious (helps you find fish), there are other advantages of these devices. Because they feature many different things, fish finders can usually tell much more than just where you could find some fish.

Location saving – most units allow you to save hotspots so you can return the next time. Still, a GPS would be great to have on board in this case because of extra accuracy.

Water temperature – when you know what the temperature in the water is, you can easily guess what fish is in there, too. Sometimes, you’ll find places where warm and cold meet.

Depth finder – again, GPS is recommended here because of charting capabilities it offers. This shows you the bottom of the lake you’re at so you can see all the fish and objects that are there.


How Does a Fish Finder Work?

Though there are plenty of different models, they all work similarly. The unit sends an electrical pulse to the transducer that transmits those pulses as sound waves. When this sound wave comes across something, it sends the info back to the transducer.

The sonar is relayed to the fish finder that’s attached to your boat. It shows all the information you need such as shapes, sizes, and compositions. Some even show vegetation and water temperature.

Is It Compatible With My Smartphone or Tablet?

Some apps allow you to connect your phone or tablet with your fish finder. This is a convenient option because it makes it possible to analyze data you’ve collected over time.

Save maps and hotspots with this feature. Also, you can map the entire waterbed in which case the app would inform you when fish appears anywhere in that area. These are all optional, and not every fish finder supports the feature.

What Should I Do If My Transducer Breaks?

You might be able to remount it if it breaks off the mount. If the transducer is broken, you might need a new one.

In the process of dry-docking it’s extremely easy to damage your transducer, and what’s most important, most manufacturers won’t replace it in this case.

However, if you don’t notice any physical damage but it’s still not working, you can read the owner’s manual for answers. Maybe there’s a setting that you adjusted the wrong way. If that doesn’t work, contact the manufacturer for help.

What Should I Do If My Fish Finder Stops Working?

If it stopped working, it’s crucial you source the problem. Charge the unit, and check if your computer can recognize it. If its screen freezes or it’s slow, restart the device.

It’s recommended you download updated firmware for your finder. If it’s a matter of water damage, check back with your user’s manual again. Also, you can always consult the manufacturer for help that’s often the best option.

Sometimes, a simple solution would be to turn in off and on because the unit may be frozen.

What Can Interfere With My Fish Finder?

The best way to minimize interference is to separate all cables from one another. If you mount your transducer to a powerful trolling motor, you might experience some interference. Plus, extra complications can occur if the trolling motor is mounted the wrong way.

You can lower your fish finder’s sensitivity to 60-75% to reduce interference. Also, think about using an RF choke on all your transducer cables.

What To Do If My Charger Breaks or Gets Lost?

You can use pretty much replace any charger with the same output as the original. However, make sure that the power output is the same before you plug in a different charger because you can damage the unit if not.

It’s best if you’d consider buying a factory replacement, especially if you have a high-end finder. This way, you’re sure that the charger you’re using is the right fit and you can avoid any warranty issues.

Can I Use The Same Fish Locator for Shallow Water, Deep Water, and Ice Fishing?

In most cases, the answer is yes. However, most people will operate differently in each situation. Because there are many models on the market, you can choose according to where you’d fish the most. Some are best for open ocean, while others are best for rivers and lakes.

When it comes to ice fishing, it’s highly advised that you get yourself a fish finder that’s made especially for this purpose.

How Do I Update My Fish Finder Software?

Most manufacturers offer firmware and software updates from time to time. They do this to fix some problems and system bugs to help your unit work well.

Brands do this each in their way, and you’ll usually have to download data from your computer. Insert the SD card with the data into your fish finder and turn it on. The unit helps you install the update and walks you through the entire thing.

Still, it’s best if you do this with patience so visit the manufacturer’s website for more information and detail.

How Much Should I Spend on One and are They Cheap?

This one is mostly up to you and what you’re looking for in a finder. Some are affordable, while some aren’t but it’s important, you decide on your budget right at the beginning of your search.

Think about how often you’d use it and what the features you’re looking for are. This will help you pinpoint a certain price. It’s a matter of your budget, needs, and preferences.

Final Thoughts on the Best Fish Finder

Finally, if you want to choose the one that suits you the best, consider the many factors carefully. Many things make a great fish finder, which is why it’s tricky to find one.

Ultimately, we recommend buying the Garmin Striker 7SV as our top choice compared to thers. It comes with a transducer, which is one of its biggest pros. It has impeccable sonar that scans the area around you in real time.
