What I like about Garmin ECHOMAP is its LiveScope system which presents a high-quality 360-angled view that it was so easy for me to detect fish with clear bottom structure. Its 7 inches touch screen offers a high-resolution display without glare.

Often users find these fish finders difficult to use due to the complex program, but that is not the case with Garmin ECHOMAP, it has a user-friendly system, and parallel aligned buttons that make it easier to operate.

The included transducer covers traditional plus CHIRP sonar features which present the three-dimensional image. In case, you don’t want to spend much, you can go with only the down scanning transducer type.  

No more lost kayaking with updated US inland maps with GPS features. It also has Wi-Fi connectivity so you can share your custom maps with others. Moreover, you can upgrade your chart plotter with g3 charts which adds additional cost. You can also update charts with a smartphone app.

Overall it is one of the best Garmin fish finders due to its quick-release bail mount. Top of all its size perfectly fits into your kayak, a perfect moderate size which you can also upgrade to a wider big so it’s up to your personal preference and your kayak or boat size.

One of the portable and size-friendly options in fish finders is the Garmin Striker series. It is available in 3.5, 5, and 7 inches display with a portable kit that perfectly fits into your kayak and adds extra protection to the fish finder.

Personally, I am a big fan of Garmin striker, it’s so easy to use, and displays each and every necessary detail from water depth, and battery voltage to even the speed of your boat. I strongly recommend this one to beginners because of its easily operated system.

You can utilize its split screen options over and above that you can mark your waypoints and navigate your location easily. This feature not only adds ease of use but also speeds up the process.

Two transducer options i.e. GT8 or G15 are available where GT8 is an ideal option for shallow water. The striker has ClearVu scanning sonar and high-resolution CHIRP sonar which creates fish arches for better tracking of your catch. This fish finder is a good option when you don’t have enough room in your kayak as it fixes on the kayak’s wall.

You also have GPS and battery options in this model but it adds extra cost.

  • Despite the smaller screen, it offers a high resolution
  • User-friendly fish finders recommended for those who are not familiar with tech gadgets
  • Problem with transducer setup

4- Humminbird 410950-1NAV HELIX 7 CHIRP MSI 

best kayak fish finder for the money

  • 7-inch screen
  • Two display modes
  • Keypad controls
  • Transducer with Dual Spectrum CHIRP 2D Sonar

Now if you are tired of spending too much time finding fish or setting up your fish finders, so here is a big relief for you. Humminbird Helix 7 with a dual spectrum CHIRP 2D sonar creates long and prominent fish arches for a quick catch and with two searching ways i.e. wide mode and narrow mode a more detailed coverage is delivered.

This offers high-quality side-plus-down imaging. The side imaging covers 125 feet on both sides of the kayak so a wide area is covered using powerful sonar signals which presents a much clear picture of fish and structure. Up to 150 feet down scanning is all that a high-quality fish finder an angler should be demanding for.

The GPS feature with 21,000 lake maps coverage and you can upgrade your maps for more detailed coverage. The vibrant colored displays distinguish the fish from the background. The only downside to this is that you have to buy an extra fuse and a wire to run into your battery. Humminbird is one of the most widely trusted and popular fish finder brands. It was quite obvious to add one of its products to the list of best fish finders for kayaks, the only reason I didn’t add it to my top 3 picks is its price. It is an expensive fish finder but I think the quality features that it offers, balances its price. Because you can’t neglect that advanced and upgraded features come at bigger prizes.

  • It is easy to install as compared to other fish finders with a solid mounting base
  • Expensive fish finder

5- ReelSonar Wireless Bluetooth Smart Fish Finder

 best portable fish finder 

  • Patented sonar fish identifier technology
  • Chargeable battery
  • iOS and Android apps are available
  • Sonar readings
  • Up to 135 feet deep sonar readings
  • GPS features are supported 

Trends just change so fast and portable small gadgets are always preferred by the users. Today, portable fish finders are now gaining the attention of the kayakers who don’t want 3 to 7-inch displays mounted on their kayaks but rather the smaller ones that also make their place in the tackle boxes. The easy Bluetooth connectivity with your smartphone or tablet just makes these portable fish finders’ go-to fishing gear.

ReelSonar Wireless fish finder is a high-quality fishing gadget that connects to the smartphone and displays underwater scenes on your screen.  Just fix it with a hook as two snap swivels are there on it for easy connection with a fishing line. It may sound strange to you to tie a transducer with a fishing line but it is actually equal to a small-sized ball obviously it is recommended to use a heavy line test when casting iBobber. All you have to do is buy it, install its app on your mobile or tablet and enjoy underwater imaging.

It has patented sonar fish identifier technology which sends fish signals and accurate readings up to 135 feet when connected with Wi-Fi and with Bluetooth it works up to 100 feet distance. Both iOS and android supported apps are available.

I wouldn’t say that it can compete with the above-mentioned fish finders that come with display screens. But the biggest advantage of a portable fish finder is that it is a versatile product. It can be present in shore  fishing, it supports dock and pier fishing, ice fishing, and night fishing as well as best portable fish finder option for kayak fishing.

  • Perfect for every type of fishing
  • Supports both methods of casting as well as dragging
  • Not a good option for serious fishing
  • Bluetooth signals interrupt
  • Much dependent on Wi-Fi signals

What qualities should your best kayak fish finder have?

You can take this as a quality factors list or a buyer’s guide for finding a suitable fish finder for the kayak because as I mentioned before selecting a fish finder is a bit different from finding the fishing rod as many factors should be considered before buying a fish finder, your location, your type of fishing, space on the kayak, your ability to use technology, transducers, price factor, installation process and top of all personal preference.

Screen Size

Today fish finders are available in different display sizes from 3.5 to a maximum of 9 inches screens. Widescreen displays more detailed information and with split screen options you can view maps, GPS and down imaging at the same time.

Although 3 inches display also offers a split screen but with a congested display, so one view at a time is preferred. You also may have issues if you do stand-up fishing on the kayak. So if you want a small fish finder that stays out of the way of your casting, then a 3 to 4 inches display is the best option for you.

On the other side, if you want a wider display, and have enough room in your kayak, then there is no reason not to spend money on them.

Sonar Type

Two popular fish-finding sonar types are available today, actually, it involves using high frequencies to achieve underwater details on the screen. These are

1- Down Imaging

2- Side Imaging

2- CHIRP sonar

Down Imaging Sonar

This one gives detailed information right below your kayak, the transducer vertically sends the sonar signals. Down Imaging sonars are usually preferred for deep water, they are good at finding depth range.

Side Imaging Sonar

If you are interested in wide area coverage, the rays scan both sides of the boat i.e. left and right. The transducer sends out the sonar signals and scans a wider view quicker than down imaging. Along with the coverage feature, you can apply filters to the images, and contour maps just to enjoy the advanced imaging.

Side imaging just offers vertical range coverage while down imaging offers horizontal area. Side scan sonars are the best options to adopt when it comes to shallow water conditions. They are also recommended for trolling fishing.

The latest fish finders offer both types of imaging via a single transducer. The kayaker can view down plus side imaging at the same time on the same screen using split screen features. That’s why dual beam sonars are getting popular day by day.


Your best kayak fish finder may have many qualities but one high-standard feature that is only available in some high-quality fish finders is Chirp Sonar Technology. This feature takes the sonar-ranging capabilities to the next level. Rather than sending a single frequency, it sends out the multi-dimensional range of frequencies for more authentic results as it shows better results than down imaging when it comes to revealing fish structure to the screen.

Depth Finder

A good fish finder for kayaks should have a depth-finding feature. When it comes to shallow and deep water fishing, depth finders are really important as certain fish lie at a certain depth of water moreover it is also recommended for safety purposes, as the kayaker will be fully aware of certain water conditions.

Waterproof Fish Finders

This may sound strange to you but adding to your knowledge, all fish finders are not fully waterproof, and the LED screens may get damaged by water splashes. So, it is recommended to go with sealed or waterproof fish finders. You can also cover your screens with a case or many kayak fish finders also comes with a protective zipper bag.

Many brands mention this feature in their product descriptions, so give this point piece of attention.

User Friendly

Many kayakers are not much familiar with the advanced technology or touch screens, so the fish finder should be easy to use with an easy operating system. Keyed panels are also available in contrast to touch screens so it’s totally up to personal preference what you pick.

Ease of use isn’t just bound to the operating system, the best fish finder should also be easily mountable.


GPS mapping is a very important feature in a fish finder, it tells you your current spot, and you can mark your spot for the next time and the right track back to your destination. I think it’s a must have feature, especially for kayak fishing but unfortunately, this feature isn’t present in every model or it adds additional cost for installing the feature.

When it comes to portable fish finders which connect to your smartphones or tablets GPS is free, as your mobiles are by default integrated with this feature. So portable ones are a good option in this case.
