The Best Kayak Fish Finder | Guiding You To The Best Fish Finder For Kayaks

Long gone are the days when you’d spend hours on end in your kayak waiting for a tug on your rod to finally pull in the day’s catch. A kayak fish finder makes the job much easier since it can help you find what can be hard to locate through the surface of the water.

It doesn’t matter if you like fishing near the coast, or on a small inland lake, because there are fish finders built for every need. In fact, some versatile models can be used for more than kayak fishing as well, so you needn’t settle for less than whatever suits your needs.

What is a Kayak Fish Finder?

A fish finder is a device that can determine where fish are located underwater. It does this by sending out deep frequency sound waves and then detecting them as they reflect. Based on the variation, a kayak fish finder can give details as to whether this is a shoal of fish, reef or any other structure that could make it difficult to get in. They feature a graphical display that lets you check measurements of distance that the reflected waves traveled.

Why Use a Kayak Fish Finder?

You can rely upon the fish finder to know whether the upcoming areas are flat and how much depth there is to the bottom of the lake. You’ll also learn whether massive structures are lying under the surface and there’s an alarm to warn you of shallow water. All these features and the main advantage of a fish finder make it a great aid on fishing trips by maximizing your catch and saving time.

Which of the Best Kayak Fish Finders Should You Get?

However, kayak fish finders are no novel invention; there are plenty of models and versions of them, which can make it confusing to find one that suits your needs. In this case, it may seem like a high price equals quality but you don’t need to splurge on a kayak fish finder to get one that does its job, although, you may need a pricier version if you want additional features.

What to Consider?

If this is your first time going kayak fishing with a fish finder, you’ll need a lesson in the basics to understand the differences between distinct technologies and models. The whole idea is to get a fish finder that suits your needs based on where you usually go fishing and how much information you need on the water below. To determine what kayak fish finder you’ll need, it’s crucial that you go through some of the features that make a decent model, and some others that offer extra perks.

The Frequency

The frequency of your kayak fish finder should depend upon where you go most often for fishing since modes are different in shallow and deep waters. Kayak fish finders function with differing frequencies, and they’re available in different versions that support either one or two modes.

If you intend to purchase one with a single mode, remember that a high-frequency version will work best in waters with shallow depth while deeper waters require waves that can penetrate deeper, so low frequencies will be desirable.

Black and White or Color Screen

Initially, fish finders would give little information, and it was all in black and white so you couldn’t tell what species would be lying under your boat and whether a school could be hiding under a nearby structure. Now, things have changed, and color screens are all the rage. Why? They provide more accurate representations and detail as well.

By providing colored imaging, kayak fishers can learn to identify species and figure out depths at which schools are present. Despite being very readily available, a few first-time kayak fishers opt for black and white screens thinking that different colors will make things more confusing. That isn’t the case; it’s much easier to look at a colored screen in bright daylight and every other weather condition, including fog.

The Power

It probably sounds preferable if you selected a high-powered fish finder for all your needs, but that won’t be beneficial since water depth can change how much power is required. For fishing in shallow water, you’ll need a low powered fish finder since you don’t require much detail, or wave penetration either. In deeper waters, however, you’ll require a high-powered kayak fish finder because it requires more energy to travel and penetrate deeper, and display detailed readings.

The Angle of Transducers

The ‘transducers’ is a form of technology that sends and receives signals by converting electrical pulses into waves of sound energy. These come in different angles, such as wide and cone, while the range is 9 to 90 degrees. When selecting a kayak fish finder for versatile fishing situations, opt for one with a more extensive angle range, since a wide angle version will operate best in shallow waters and narrow ones work best for deeper waters.

GPS Tracking

Not all kayak fish finders possess a GPS tracking system, but it sure does help to have it. You’ll need to decide between getting GPS and not, based on where you usually go to catch fish. If you prefer to fish inshore, there’s not much use for a GPS system because much of the land is visible around you. On the other hand, fishing trips in open oceans, untraced swamps, and bigger lakes require that your kayak fish finder have a GPS system so that you can track your location as well as any active areas.

The Graphical Display

You’ll want to be able to read information and readings accurately as well as check any hot spots around you. For this reason, you’ll have to check whether the screen size is big enough and if the brightness is high enough to allow daylight visibility. A large screen offers clarity since you can easily distinguish between different readings.

Wi-Fi Connectivity

Newer models of kayak fish finders come with Wi-Fi connectivity, which is helpful since it can then sync with your smartphone, giving you readings in the palm of your hand. This also has an element of portability to it that lets you carry your fish finder everywhere instead of just mounting on your kayak.

Your Kayak

These fish finders hold essential data that can help you trace schools of fish, but you’ll want to focus on the waters as well. This makes it necessary that you safely mount your kayak fish finder instead of holding it or in the case of bigger screens, place it anywhere on your kayak. You’ll require a mounting system that suits your kayak model and shape. Most fish finders come with their mounts, and these are commonly inclusive of various kayak models.


Even if you spend big bucks on a recent model, it’s inevitable that the brand will release an advanced version in the upcoming years. While your model won’t be obsolete, it’s best to know whether it’s compatible with a different transducer, sonar or GPS system. This benefit means that you can come to develop a unique fish finder set up that meets your needs better than any ready-to-use type on the market.

Portable or Not?

You’ll also want to decide if you prefer a fish finder that can be carried in your kit wherever you go. If you like to switch between ice fishing, kayaking, and fishing off the dock, then a portable fish finder will work better. But if it’s only kayaking that piques your interest, then a kayak fishfinder will work best.

Transducer Included

It’s desirable to get a kayak fish finder that comes with a transducer included in the pack. This makes it much easier to install and set up in your kayak. Check for the style of the transducer, whether it’s thru-hull, transom mount, in-hull, or trolling motor. Remember that each type operates differently with a kayak, based on the materials it comprises of and its shape.

The Type of Fish Finder

Just like with other categories of marine technology, there are different types of fish finders, with varying levels of advancements. Some kayak-fishing enthusiasts prefer older models while others search for the best kayak fish finder with all the latest upgrades like GPS, Wi-Fi connectivity, and so forth. You’ll need to be clear as to what kind of fish finder you want. Otherwise, it’ll be difficult to choose from the wide range of available options.

Standalone Fish Finder

This is a simple option, and it just shows what’s underwater. Advanced versions give high-quality graphics displays on bigger screens, and they’re very affordable as well. This option is the best for experienced kayak fishers who are on a budget and only need a little guidance as to what’s underwater. Another reason why standalone kayak fish finders work best is if you usually go fishing in smaller inland water bodies instead of the coast.

You won’t feel stuck by getting this type of model either, because you can always upgrade it to a combination fishfinder with a chart plotter by adding a GPS to your setup. In most upgrade scenarios, the larger screen of a standalone fishfinder works best.

Fish Finder with Chart Plotter

A combination fish finder would be better suited for middle-sized boats and kayaks taken to a range of different waters. Since you’ll be in larger water bodies like rivers or near the coast, you’ll require a GPS feature that helps you get near the best place where schools are usually resting.

This way, you can navigate your way to the fishing grounds without spending too much time guessing which route would be best. If you use a black box sounder module, it offers the benefit of turning a chart plotter into a complete setup once you install a transducer.

Networked Fish Finders

A fully connected and networked fish finder system can be found at all major brands so you won’t have any trouble purchasing one. These systems offer the most connectivity because they support a diverse range of data sources, such as vector GPS, radar, and satellite radio.

Additionally, newer models will have WiFi and Bluetooth, giving you the opportunity to leverage information from the palm of your hand, using your Android or iOS-based smartphone. There are even multi-display systems that provide you more data, but this is mostly needed for larger boats or if you have your sights set on kayak fishing away from the coast.

The Technology

It’s crucial that you understand the type of technology that your fish finder is packing because if you’re a weekend warrior who visits the same lake every week, you won’t need as many features as someone who only goes once every season or so.


Sonar has come a long way ever since the first models of fish finders, but they remain the primary method to detect fish species. They take a wide-ranging but less detailed scan of the parameters around your kayak to give you a simple outline of what’s underneath and around. You won’t be able to identify the species or get a clear picture as to the size, but most kayak fishers prefer this method since it’s better than guesswork.

Down and Dual Imaging

This type is more advanced than a traditional sonar-based transducer because it casts a scanning beam straight below your kayak.  It gets a clear scan of the area directly below your kayak and gives you data in the form of 2D imaging.

The other technology usually equipped with a down imaging system is a dual imaging one, which scans the areas around a kayak as well. With both features, you’re able to get more representations of what’s underwater, know how deep they are and what temperature the water is.


Fishfinders with built-in GPS systems are considered to be top-tier devices because of their extensive lineup of features. Mainly, you’ll be getting all the perks of a down and dual imaging fish finder, and more, i.e., a more prominent display, photographic-like imaging, and precise detail. Of course, the GPS offers its benefits, like data on underwater contours and surrounding topography that allow you to create different travel logs.

The Frequency of The Transducer

The nature of inland fishing has changed drastically; it’s no longer known as the passive pastime activity because there’s much more of a strategic aspect involved. This would explain the developments in technology that once-modest transducers have gone through. There are now transducers with frequencies that let you see what’s below or at the side of your kayak, and some models can give a 360-degree view.

Related: Best Fishing Kayak

Fishfinder manufacturing brands are making rapid upgrades to their systems so kayak fishers can have a more extensive assortment of options to select from. This includes different bandwidths, directions, and frequencies that add to the overall experience. Here’s some of the basic terminology you need to know about transducers concerning their frequencies before you can make a decision.

Higher Frequencies

These transducers have more wave cycles every second and shorter wavelength as well. This offers you the advantage that you’ll be able to see more details underwater, which includes smaller species of fish. However, you won’t be able to see deeper than shallow waters so you’ll be limited to smaller inland water bodies.

For instance, a 200kHz frequency transducer produces a sound wave that’s about 1/4th of an inch. Therefore, it will be able to detect fish that are almost the same size. The high-frequency capability gives a clear picture of what’s at the bottom, and if you want better resolution, a 455kHz or 800kHz transducer will do.

Lower Frequencies

This type of transducer delivers longer waves at the tradeoff of fewer waves per second. In simpler terms, you’ll be getting less information as to what’s underwater, but your transducer’s waves will reach greater depths.

A 50kHz frequency transducer produces waves that are almost an inch long, so it’ll only be able to identify species of fish that have similarly sized air bladders. So while you won’t get any details of smaller fish, you do get better functionality in deep waters like Lake Michigan.

Dual Frequencies

The name says it all; these transducers can release shorter waves at higher frequencies and longer waves at lower frequencies. Using an element of piezoceramic nature, i.e., vibrating crystals, the transducer sends and receives dual frequency pulses simultaneously.

Quadra or Dual Beams

Highly advanced models of transducers implement the use of varied elements, and each of these operates in a specific direction.

Things To Remember

  • Choosing a low-frequency transducer gives you the benefit of finding more massive structures, which could be prime hiding locations for fish.
  • On the other hand, high-frequency transducers don’t provide much detail as to what’s lurking right under your kayak.

The Type of Transducer

The process of choosing the best kayak fish finder for your needs takes a lot of time, and it’s not enough that a transducer is included in the package, but it should be compatible with your boat as well. Aside from being compatible, the mounting system of a transducer can significantly impact the quality of information you get. Also, specific mounting systems take longer than others, and the results you’ll get from each type of mounting system differ significantly as well.


The most challenging transducer type to install is the thru-hull since you’ll mainly be drilling right through your kayak. However, it does provide clear and high-quality signals because the transducer is placed just right. These often come in the form of triducers, which have extra perks like temperature and depth sensors.

Transom Mount

This is easier to install and can be done with almost any kayak fish finder that comes with its bracket. You can usually adjust the angle on these brackets, which are either bolted or screwed on to the transom. The transducer hangs below deck, at the back of the hull. It’s much easier to install than the thru-hull design, but the placement of the transducer can result in rough water flow.


This type of transducer doesn’t need to come in contact with the water to provide a signal. Instead, it can be placed inside the kayak using a durable material such as epoxy or silicone. This may seem like the most comfortable option, but it’s limited to fiberglass-based hulls and doesn’t work with kayaks that have steel or cored hulls.
