Garmin Striker 4 Review

Any angler who wants to take the guesswork out of fishing must equip themselves with a fish finder. And not just any fish finder, but a quality one with great features that actually make your work much easier.

But, there are so many fish finders in the market to choose from, so deciding on one can be a bit daunting, especially when you’re a beginner and haven’t given any of them a try before.

In today’s review, I’ll show you everything you need to know about the Garmin Striker 4 before you buy it. This is one of the most popular fish finders chosen by anglers, and most have good things to say about it.

If you’ve not come across it yet or are wondering exactly what it has to offer, this Garmin Striker 4 review will provide a close look at its features and what differentiates it from other fish finders in the market.

Features to Look for When Buying a Fish Finder

Before we get to the Garmin Striker 4 review, let’s first go through features that you should be looking for when buying a fish finder.

By knowing the things to look out for, you’ll be able to choose a fish finder that’ll serve you better once you’re out in the water.

Water Resistance

If you’ll be mounting your fish finder on a small and open vessel, then you need to look for a unit that’s waterproof. Otherwise, it’ll get damaged by water within a short period of using, and you’ll be forced to buy a new one.

Most fish finders will have either an IPX or JIS rating. With a rating of 7 or above, you can expect your unit to perform well without getting damaged in the rain, snow, shower, or if splashed with water.

If it has a rating of 8, it can stay underwater for more than 30 minutes without becoming damaged. It’s best to get one with a higher rating so that you can have peace of mind when out in the water, especially on your kayak or small boat.

You’ll be assured that even if water gets on it, there’s nothing to worry about.

Display and Screen Resolution

Struggling to read a fish finder is definitely something that no angler wants to deal with when they want to enjoy their fishing trip. And that’s why display quality and screen resolution are features that you should give thought to before buying a unit.

To ensure that you get a clear display, look for a screen that has a resolution of at least 240×640 pixels. However, if you can afford a unit with a better resolution than that, it’s best that you go for it.

That way, you’ll have no problem with the clarity of the images or numbers shown on display.

Besides resolution, it’s also a good idea to check backlight functionality. It should be able to be customized for easy viewing during the day or night, in all light conditions.

Frequency Selection

Some fish finders come with a single frequency, which means that you can only send out one frequency at a time, and receive a single frequency back.

This requires a lot of patience and can get frustrating if you’re eager to get quick results. Others are able to send out dual frequencies, while others can handle multiple frequencies.

The kind of frequencies available will also determine the cone angles that you’ll be working with. So, if your unit only supports one frequency, you’re likely to miss out on fish on a wider area, or those that could be in deeper places.

But, when it has multiple frequencies, you’ll be able to get back data from various angles, and this will help you find more fish.


Modes have a lot to do with how a fish finder operates and how you get to interpret the sonar information. Many units use the traditional Mode, which is the most basic. With this mode, you’ll be able to see details about the depth of the water and details about objects and fish at the bottom.

Other modes, such as flasher and split-frequency, allow you to see more details at once on the screen, including depth, sonar information, and GPS feedback.

The Garmin Striker 4 Review: Features and Benefits

If you’re looking for an affordable, portable fish finder with a built-in high sensitivity GPS, the Garmin Striker 4 is a worthy option.

It’s smaller than most fish finders in the market, but it’s feature-rich, which is what you should be looking for at the end of the day. If you’re looking for a compact fish finder, this can be a great option when compared to other small units in the market.

It’s laden with features that ensure that you don’t spend your precious time trying to craft fishing lures and waiting – when you have no idea whether there are any fish around your spot or not.

It comes in two versions, 010-01550-01 and 010-01550-00. Even though they have different part numbers, their specifications are pretty much the same.

What makes these two versions different is the documentation. That ending with “00” gets English documentation, while units with “01” at the end of their number have worldwide documentation.

With this fish finder, you can say goodbye to blind angling and start actively looking for fish, which will make your fishing more successful.

If you’re going to be fishing from a kayak, canoe, or boat, the Garmin Striker 4 has a lot to offer you. Also, this fish finder can be great for beginners, so if you’ve never used a fish finder before, you should definitely read this review to the end.

Here’s a quick look at its pros and cons:


  • It’s a low-budget fish finder, with advanced features that you might not find in most compact units.
  • Comes with a built-in, highly sensitive GPS capable of saving up to 5,000 waypoints and showing boat speed.

CHIRP Technology

CHIRP stands for Compressed High Intensity Radar Pulse and is used as an alternative for the traditional sonar technology.

Using a transducer, the sonar technology sends out a single frequency and receives it back to gain information for interpretation on the fish finder.

But, with CHIRP technology, multiple frequencies are sent out at once and also received back. On reception, each of them is interpreted individually.

By being able to provide a large amount of information at once, the CHIRP technology gives more clarity and details about fish arches, target separation, depth, and so on.

Most compact fish finders are fitted with sonar technology, but the Garmin Striker 4 has the more advanced CHIRP technology. This is one of the main features that sets it apart from its competitors.

The Garmin Striker 4 transducer supports 77kHz and 200kHz CHIRP frequencies. If you choose to use the 77kHz, you’ll get a larger cone angle (45°) that covers a large area. However, this will provide less detailed information, and there’s also the chance of missing fish in deeper areas of the water.

Using the 200kHz provides you with a narrower cone angle, which is 15°. However, while it covers a smaller area than the 77kHz frequency, it provides greater detail. It’s also able to reach into deeper areas in the water, such as ledges, so that you don’t miss any fish.

You can also upgrade to a GT8 or GT15 transducer to send out more frequencies and receive more detailed information.


The Garmin Striker 4 fishfinder has a small display with a 3.5-inch full HVGA touch screen. It has a resolution of 480×320 pixels.

While this display is smaller than most fish finders, it has more features that make it quite functional. Also, if you’re interested in a compact fish finder, then this is the ideal display size to look for.

Thanks to its good resolution, this display shows clear and crisp images of fish, water objects, and other information on the screen.

The screen has backlights that you can adjust to fit the light at the moment. This means that you’ll not have any trouble viewing the display, whether during daylight hours, when the sun is bright, or when it’s dark.

The display is vertically oriented, with a few buttons for easy navigation. It has a split-screen feature that allows you to view all the important information and also has a zoom feature.

High-Sensitivity GPS

The high sensitivity GPS is one of the main features that sets the Garmin Striker 4 apart from other fish finders you’ll find in the market.

With the Striker GPS, you can not only locate fish precisely but also track your movements and fishing spots. It allows you to mark your favorite fishing spots so that you can come back to them whenever you want.

It can store up to 5,000 waypoints, so you can save a lot of fishing spots. This saves you the hustle of trying to remember where you last had a successful catch. With your waypoints, you can always go straight to your spots and proceeded with your angling.

Besides storing fishing spots, you can also include waypoints that allow you to get back to the boat ramp or shore easily. This way, you’ll not have to worry about getting lost, and you can explore the waters with a peace of mind.

Other than it’s navigation capabilities, the GPS on the Garmin Striker 4 also keeps track of the speed of your boat. Together with your waypoints map, you’ll be able to approach your fishing spots at an appropriate speed that does not disturb the fish.

Garmin Striker 4 Review


Most anglers choose the Garmin Striker 4 became of its several modes. These modes make it easier to read and interpret information displayed on the fish finder.

Here are the various modes available on the Garmin Striker 4:

Traditional Mode: This is the mode that you’ll find on most fish finders. If you’ve used a fish finder before, then you’re probably familiar with the traditional Mode.

When using this mode, you’ll get information about how deep the transducer is in the water, and receive information about the bottom surface, fish, and other underwater objects.

Flasher Mode: The flasher Mode utilizes a circular scale that displays the depth levels of the water and the sonar information. Depth is shown in the middle of the scale, while color flashes indicate sonar information.

You can determine the strength of the sonar information from the colors that are displayed. The flasher mode can especially be useful when you’re jigging or ice fishing.

Split-Frequency Mode: We’ve already seen that you can use dual frequencies with the Garmin Striker 4, which are the 77kHz/200kHz. The split-frequency mode allows you to view information from both frequencies on the screen at the same time.

A horizontal split view also allows you to check your waypoints map and sonar screen simultaneously. This way, you can see your GPS location, the spots that you’ve marked along the way, and sonar information at the same time.

Another mode (section number mode) also allows you to see coordinates and GPS speed alongside other details.

IPX7 Waterproof

The Garmin Striker 4 has IPX7 waterproof features to protect its quality and allows it to remain in the best working condition for long.

This feature allows you to use this unit in the rain, and it can even be submerged in freshwater to up to 3 feet without getting damaged. It’ll also remain in good condition if you’re working in snowy conditions.

Depth Capability

In salty water, you can use the Garmin Striker 4 to a depth of up to 750 feet or 288 meters. It can reach a depth of up to 1600 feet or 487 meters in freshwater.

However, note that you can only achieve these depths of you upgrade your transducer. The manufacturer recommends upgrading to a GT8 or GT15 transducer for better functionality.

If you stick with the transducer that comes with the Garmin Striker 4 box, you might have to make do with about 844 feet or 244 meters of depth.

Fish ID

If you’re not yet conversant with interpreting sonar returns or simply want to get everything in its easiest form, you’ll love the Fish ID feature on the Garmin Striker 4.

To find this function, go to the menu from the sonar screen, then click on the sonar setup. Click appearance, then head to fish symbols.

Here, you’ll find 4 options of fish ID settings to choose from. The most beginner-friendly one will show you fish to indicate presence and a number that shows how deep in the water they are.

Other settings will only indicate fish presence with no depth, while another one includes fish icons, depth numbers, and a 2D Sonar image.

If Garmin Striker 4 is your first ever fish finder, then you’ll have all the time to get acquitted with the various sonar returns. With time, you’ll be able to make precise interpretations without using the fish ID.
