The first on the list of Striker 4 with a massive number of satisfied customers worldwide already (We are also one of them). Garmin is a big name that has manufactured hundreds of fish finders.

We have to say that all of the products are better than others. On the other hand, Striker 4 has a small body with a flat-screen that is 7 inches long. However, the display is also available in other dimensions.

It has a built-in GPS integrated into the device that works efficiently. The device works perfectly on 17V. The Catch about this fish finder is that it can find the target up to 1600ft bottom in the seas.

Garmin also stores data on several small and giant lakes in the USA. It also enables users to create more maps and mark their favorite fishing spots accordingly. We loved it!

Lowrance believes in advancement. It keeps an eye on the market trends and always comes up with something incredible that one has to admit its rich features. Similarly, this device by Lowrance is another masterpiece.

The display is 7 inches long. However, it comes in five different display-size variations. The device is worth buying; you can easily feel the difference. We believe that Reveal 5 has made fishing much easier. The catch is the device has more than 8,900 maps of different lakes, rivers, and streams in the USA and Canada so that you don’t have to spend time creating a new map of the place.

It certainly saves time and helps you stay focused on fishing only. This allows you to view a clear and concise view of the underwater on the split-screen. The screen has a high resolution. Another catch about the device is that it has an auto-tuning sonar system that automatically adjusts and saves the settings for later use.

While this device, too, comes in four different variations, and others have GPS integrated into the device already with different display settings and variations. The screen has a high resolution and is 4.3 inches long. It also shows an underwater view on the split-screen. For the price, this also has a mapping system.

Lowrance has always been good this term; it has incorporated hundreds of maps already in almost all of its fish finders. The device offers a high frequency that can detect the movement of the fish even several meters deep in water. The display gives a precise view of the movement underwater.

We suggest that if you are new to this fish finder thing and want to give it a chance, then you should begin it with HOOK2 by Lowrance. Learn and get professional.

Turn on the fish finder and turn on its WiFi feature and then connect it to the hotspot of your device. You can easily view and track the underwater movement of fish on the screen of your device connected.

What To Look When Choosing Best Kayak Fish Finder – Buying Guide

What features do you observe in a fish finder? We have listed out some exclusive features of a quality fish finder. Before having a purchase you should look for the following properties. This article will help you to decide on the best option. 


Fish finders for kayak show display in different sizes. Different manufacturers create fish locators display with screen sizes from 4 inches to 12 inches. Furthermore, screen resolution varies from device to device.   

Method of Imaging

Usually, a kayak fish finder uses two types of imaging:

  • Downside imaging: Fish finders use transducers by sending sonar underwater. If you want to do fishing in deep waters, downside imaging can give you a clearer view of the targeted area. However, the quality of imaging depends upon the number of transducers that a fish finder uses.  
  • Sideways imaging: Contrary to it, sideways imaging is used in shallow water. If you intend to do fishing in streams, lakes, and ponds, you should choose a fish finder that casts sideways imaging. 

Further, the sonar range may vary between 150ft to 350ft. The best sonar transducers can go through sonar beams at different angles to increase accuracy and coverage. 


While rowing a kayak, fish finders feature with fish locator and depth locator. An authentic fish finder can measure the depth of water even when the kayak is at a higher speed. Common fish finders can measure the depth of water from 1meter to 400 meters. It all depends upon the capacity and specifications of the fish locator.

Screen Size

The different manufacturers produce devices with different screen sizes. Generally, the screen size may range between 4 inches to 12 inches. The screen size is measured in a diagonal direction from the top left corner to the bottom right corner. A 7 inches screen is considered large enough to get a clear view of water bodies. 

What Extra Features You Should Seek


For beginners, fish finders are available under $150. However, with advanced technology, the prices of fish locators have risen. Fish finder price increases with technologies like fish locators, high screen resolution, sonar beams, and depth locators.  

Transducer Capability & Space

The transducer uses sonar beams to view in-depth information about water. Without transducers, fish finders cannot detect anything, and the screen will get blank. 

The beam of sonar waves ranges from low frequencies to high frequencies. Beams with low frequencies can detect the depth of water bodies. Narrow beams allow higher depth with fewer details. On the other hand, beams with higher frequencies can penetrate less depth but provide detailed information on water bodies. 

Water Proof

According to IPX7, all fish finders are water-resistant. You can keep the fish finder merged in water for nearly 30 minutes deep up to 1 meter. However, the capacity of water-resistant may vary per brand. 

Choosing The Best Fish Finder On The Basis Of Techniques

Deep Water 

Firstly, you need to decide how deep you want to fish. For more in-depth fish finding, you need a downside Imaging Sonar. Downside Imaging Sonar helps the fish finder to see beneath the boat as well. On the other hand, if you like to do fishing in freshwater, lakes, or streams, side imaging Sonar is the best choice.

Transducers with Down Imaging sonar use a vertical angle to find the fish. Down imaging can give clear imaging even if your kayak rows faster. 

Structure fishing

Structures refer to underwater landscapes. Depth, bottoms, and contours remain to change within lakes and underwater. Fish finders help users to locate underwater structures. The actual science is to understand how fish relate to these physical landscapes. Advanced fish finders use Mapping and other techniques to make the view clear and better. 


Fish finders to work in shallow water require certain specifications and customization. For instance:

First, in shallow water, a higher frequency of sonar beam helps is effective. Higher frequencies do not work in depth. But it can cast the best image quality, unlike low-frequency sonar beams. 

Second, you need to adjust the depth of the fish finder. Keep the depth minimum in the setting. It will help to find out the bottom easily. 

Both types of imaging – Side imaging and down imaging work conveniently in shallow water (though side imaging is the best one). A fish finder with these qualities can help you find the best fishing experience.

Saltwater vs. Freshwater

In salt water, the sound amplitude for a kayak fish finder is greater. The reason is simple. The heavy metals, mineral ratio, and living organisms make it possible. However, fish finders often have the option to select the type (saltwater, freshwater) and depth of water (deep or shallow). 

So, before purchasing, you can check out these specifications. Keep in mind many fish finders with low quality are unable to detect the quality of water. It surely affects the performance and life of the fish finder.


This research and in-depth analysis have come to an end. For us, the best fish finder on the kayak is “Striker 4 by Garmin”. This is 100% affordable; whether you’re a pro fisherman or just a beginner, it will work for you! We are extremely impressed by the body design, durability, and exceptional performance of the device. The frequency can even detect the tiniest movement within a depth of 1600ft depth. So many features came in the small fish finder, which made us love it!
