It may be difficult to locate fish accurately when you’re out on the water. Sometimes the water is cloudy. 

Often the weather is all gloomy. Anglers who go fishing at night may have trouble working a flashlight while their hands are busy.

At other times, submerged objects, debris, and vegetation can be difficult to see fish in the water. During times like these, a fish finder can be a lifesaver. Although this tool is often overlooked, we are going to discuss one of them in depth in this Garmin Striker 4 review.

By the end of this review, you will learn a lot more about fish finders in general, how the Striker 4 Garmin works, whether it operates as expected, and whether we recommend giving it a shot.

With all that to get through, let’s get started right away!

What are Fishfinders?

Fish finders are electronic devices, made up of a transducer and a display. The transducer uses sonar technology to capture what is happening underwater and transmit them as images on the display.

This is how it works: The sonar unit deploys high-frequency sound waves through the water, which bounces off of underwater objects and returns. 

By processing these sound waves, a fish finder can find out things like water depth, submerged structures, and most importantly, where fish may be hiding.

The display of the unit will show you what is happening underwater. These displays can be black and white or colored. 

Depending on the make and model of your device, you may end up with extra features as well. Some are portable and others need to be fitted onto a spot.

There are lots of different sorts of fish finders out there. To find a rundown of the best portable fish finders out there and what they do, check this out.

Garmin Striker 4 Sonar Fishfinder Review

Garmin Striker 4 Fish Finder

This Garmin portable fishfinder is one of the most popular options for anglers everywhere. Because it combines affordability with functionality, it is accessible for everyone. Also, the fact that it is portable is super convenient–there is no need to mount it anywhere.

With that being said, let’s talk about the features of the Garmin Striker 4 Built-in GPS Fish Finder.

Garmin Striker 4 Fishfinder Review: Features and Capabilities:

These are some of the most impressive things about the Garmin Striker fishfinder:

CHIRP Sonar:

The fishfinder features a Garmin chirp sonar which sets it apart from many similar devices. This is because the Garmin Striker 4 CHIRP gives you a higher level of visibility and clarity, so you can see further and with more precision.

The CHIRP Sonar sends a constant sweep of frequencies which offers a wider range of data; as a result, this Sonar can create cleaner, crisper fish arches with improved target separation, so you can see what is happening underwater more clearly.

Clear Vu Sonar:

This scanning sonar tells you in greater detail what is in the water around your boat. The high-frequency sonar gives almost photographic images with detailed and accurate representations of objects, structures, and fish in the water. 

This is due to both the Garmin Striker 4 transducer and the LCD that offers a clear perspective and insight into your surroundings.

Waypoint Map:

The built-in high-sensitivity mapping GPS of the Garmin Striker 4 is another bonus when it comes to what it has to offer.  It lets you locate your current position on the water quickly and accurately. 

Moreover, you can use it to mark the points with plenty of fish so that you can go back to them on your next fishing trip.

But there’s more! You can even mark things like boat ramps, docks, and other places on the water to view and navigate these positions when you need to. With the Garmin sonar GPS map, you can share the waypoints you make with other strikers as well.

It can identify a maximum depth of 1,600 feet in freshwater and 750 feet in saltwater.

Built-in Flasher:

Besides letting you find fish; the Garmin Striker 4 Portable Kit will also allow you to view the bottom of the water body while ice fishing or jigging. This lets you know if it is solid/firm or muddy. This comes in handy when ice fishing, and should be in your toolbox for winter fishing.

When jigging, it lets you see how high your jig is being lifted and whether the fish are swimming toward or away from the jig. As a result, you can figure out whether you will catch a lot of fish on that particular day, or in that specific spot.

Characteristics of the Garmin Striker 4 Chirp GPS Fish finder in Use

Now that we know what features make this device special, let’s see how it holds up when you’re using it out on the water. In this part of the Garmin Striker 4 review, let’s take a look at the capabilities it has for a smooth fishing experience.

Simple Interface:

The fish finder has a simple, keyed user interface. This, along with the dedicated buttons and clear display makes it easy to maneuver the device and identify the locations of fish and the various mapping locations.

Also, the display has two models: one that is 3.5 inches and the other that is 7 inches. As a result, you get to choose the size of the Garmin device.

Speed Check:

Ever lose track of your speed when trolling or kayaking? The speed at which you are moving your kayak, canoe or boat has a major impact on the efficiency of the lure you are using as well as the kind of fish you are trying to catch.

The Garmin striker 4 fish finder allows you to track your speed so that you can continue at the ideal speed for the perfect fishing or boating experience. You can check the vessel speed on the display and adjust accordingly.


The Garmin striker 4 comes with in-built GPS capabilities that help you identify the location of fishes with a great deal of accuracy. With this feature, you can be sure of the precision of all fish finding tasks. If you have a favorite fishing spot, you can use the GPS to locate that spot.

It is also great for tracking speed. You can use the GPS technology to regulate the speed of your vessel as we mentioned above. 

Therefore, you will know when you arrive at a particular location. You can also view details about the underwater terrain on the Garmin striker 4 with the help of the GPS.


The display is one of the best aspects of the Garmin Striker 4. It lets you confirm whether you’re trolling/boating at the right speed. Even if you aren’t a tech wiz, you can easily figure out how to work the display (and overall unit) very quickly.

The Garmin Striker 4 has a touchscreen and provides a number of committed catches for a simple route. More importantly, the display has a practical screen size of 3.5-inches which conveys 200 kilohertz, creating a clear and perfect picture. 

You can also get a less detailed image with the 77 kilohertz. The higher kilohertz gives you better quality images, although you don’t get a bigger filter zone.


The Garmin striker 4 contains several modes. These include:

  • Traditional mode
  • Section number mode
  • Flasher mode
  • Split frequency
  • Waypoint map mode
  • Both the sonar screen and the waypoint map combined

With the traditional mode, you can quickly and easily identify structures and obstacles beneath the water. This is the mode that lets you know where schools of fish congregate.

The Split Frequency mode displays both the 70-kilohertz and the 200-kilohertz images next to each other. However, the traditional ode is most frequently used by anglers when scoping out the conditions of the water.

Besides this, you can observe what’s under your fishing vessel in two separate spheres, with the thinner imagery on one side and the wider one on the other. The flasher mode is meant to show you the level of the water depths.

You can use the section number mode to view the speed at which your boat is traveling. The waypoint map mode lets you easily trace your path to a previously marked spot. All these modes and features help make the process of fishing much easier and more convenient.

Portability Kit:

Some Garmin Striker 4 devices (the Garmin Striker 4 with Portable Kit) include a portability kit. This lets you take the fishfinder with you wherever you go. 

Just place the device in the portable backpack and move it around with you easily. The kit also includes a rechargeable battery with a charger, a suction cup transducer, a built-in transducer cable management, and a mount for the device.

Major Features:

  • Dimensions: 3.60 x 1.60 x 5.90 inches
  • Weight: 8 ounces
  • Display Type: HVGA color
  • Screen Resolution: 480 x 320 pixels
  • Brand: Garmin

The Pros:

  • The backlit feature makes the LCD screen visible even in direct sunlight or the dark.
  • Waterproof and long-lasting.
  • Battery life is reliable and lasts a long time.
  • Easy to install and/or mount on a kayak.
  • It is budget-friendly and affordable.
  • Water temperature log and built-in flasher make ice fishing easy.
  • Sturdy and rugged design.
  • Setting up waypoints and returning to them is simple and convenient.

The Cons:

  • Doesn’t include a Micro SD card reader.
  • User instructions aren’t detailed or clear.

Why We Recommend It:

The Garmin Striker 4 Fish Finder is great because it comes at a very good price while remaining super functional. Furthermore, it has precise representations and near-photographic image quality. The device is pretty easy to use, has a display that comes in multiple sizes, and sufficient maximum working depth in both salt and freshwater.

This fish finder includes a waypoint map so you can easily mark and recollect things like vegetation, rocks, flotsam, brush, and other underwater obstacles. 

It helps you keep track of your vessel speed, identify fish locations, share details with other strikers, and a lot more. Pretty impressive for a small and unassuming device!

Comparison with the Garmin Striker 4 Plus

Wondering if you should go all out and get the Garmin Striker 4 Plus device? The device may seem like a drastic upgrade from the regular Garmin Striker 4 fish finder, but how are they different.

Well, according to the Garmin Striker Plus 4 review, this unit differs in the following ways. It has a built-in quickdraw contour mapping software that allows you to construct and store maps with 1-inch contours for up to 2 million acres.

It also has a 4.3-inch display, larger than the regular Striker, and an intuitive user interface, making it clearer to see things underwater. 

Moreover, the device gives you more precision and clarity, while letting you store up to 2 million acres of content easily. Other than that, it doesn’t have much of a difference with the more conventional fish finder.

In Summary

Sonar fish finders are a blessing for people who go fishing in waters with lots of vegetation, boulders, and debris. Finding fish with such obstacles can be difficult, especially if you cannot see what is happening around you.

This Garmin Striker 4 review showcases all the useful features of this fish finder. The CHIRP sonar and the transducer work to give you the clearest imagery possible of the underwater terrain, alerting you to the presence of fish. 

It also lets you see where you are going and return to fruitful fishing spots. And for the price, can we really ask for anything more?
