Buying guide for Fish Finder

Best Fish Finder Buying guide

When looking for a great kayak fish finder, there’s more to consider than whether it has imaging sonar or a high-definition display. Unfortunately, most fish finders will be designed to be installed on larger powerboats. (Find the Best Trolling Motor For Kayak)

Kayak-specific designs are few and far between. As a result, the best systems for your yak are compact and portable. A large chunk of them requires 12V power, and you’ll need to consider where you can put them unless you use the bobber types of fish finders.

Here are some of the things you need to consider when purchasing your next fish finder to help catch more fish.

Will the Fish Finder Fit?

When purchasing a fish finder, the first move is to determine where you can install it. Put your yak on the water and start paddling. Act as if you’re fishing and check if the fish finder obstructs your view. Experiment with different strokes to be certain you don’t collide with your mount.

Can You Still Cast?

Begin fishing and pay attention if you can cast without interference. Even when water is clear, the fish finder needs to be placed low because of low-hanging vegetation. It may require a mounting arm, or you use the center console where fitting makes sense.

Battery and Cables

If you’ve figured out where to put your fishing kayak fish finder, you’ll need to figure out where to run the battery and transducer cables. It’s important to keep them dry, as well as any fitting plates, and to secure cables in place.


It may be a viable option here, as some fish finders are compact but pose a risk of dropping into the water. Permanent designs can provide a safer option, but they will be exposed to the elements and damaged or stolen during transport.

Frequencies Used

Fish finders use sonar to locate fish. Dual frequencies are used in lower-cost models, while CHIRP, or Compressed High-Intensity Radiated Pulse, is used in higher-end models.

  • Low frequencies penetrate water, allowing the fish finder to see deeper, but it can lack the fine detail required to locate schooling fish.
  • High frequencies provide more precision for pinpointing fish, but they struggle to move through the water. They can’t tell you anything about the water’s bottom, particularly if it’s deep. Dual frequencies enable your fish finder to carry out both readings simultaneously.

The transducer beam angle isn’t as important as you might have been led to believe. Fish are seen suspended in the water column at wider angles, while fish near the bottom is narrower.


Longer pings are used in CHIRP technology across many frequencies. CHIRP systems outperform dual-frequency systems in terms of accuracy and data transmission to the fish finder.


A fish finder transducer transforms electrical energy into sonar waves and the other way around.

Cone Angle

It is the width of the sound wave that your boat emits into the water. The bigger the covered area, the wider the cone. The lower the amplitude projected back to the transducer, the further the sound wave goes down. Image distortions result from a lack of precision.

Frequencies and transducers won’t work properly without your cone angle. Many consumers consider the cone angle to be the most important aspect when shopping for a depth finder transducer. The frequency of a depth finder is also linked to its cone angle.

The cone angle is the width of the beam sent out and down through the bottom of your fishing boat. The cone angle is named after the shape of this feature, which is narrow at the top and gradually widens as it delves deeper into the water, much like a cone.

The transducer beam angle is another name for this element. Your sonar signals would provide a larger field of view with a wider angle.


The frequency of the sound wave produced by the transducer is referred to as this. The wider the cone angle, the higher the frequency. Higher frequencies are best for shallow waters, and lower frequencies are better for deep waters.

The way you mount a transducer makes a big difference in your fishing experience. You may put them together in a variety of ways.

  • Hull mounting has been around since the dawn of kayak fishing. Cut a sponge to fit the transducer and position it at the bottom of your kayak’s hull. It loses a little of signal, but not much.
  • Transom mounting: This is where you connect an arm to your kayak using a mount. The transducer will be completely immersed in water, as it should be. However, if you run into
  • rocks or stumps, it will be destroyed.
    Scuppers for common transducers: Kayaks come with scuppers for common transducers. If your kayak has this capability, look for fish finders that will suit you. These are frequently used as optional extras with a higher price tag.

Maximum Depth

A fish finder should have suitable depth finders for the areas you’ll be fishing. Manufacturers offer a max depth.


Your fish finder’s display is a key feature in how well it works for you. Pay special attention to the display size, color, contrast, and detail. These will determine how well you can read the returning down imaging sonar signals and identify fish.

One of the most important things to consider is how many pixels your display has. The more pixels, the clearer, and smoother your image will be, allowing for easy deciphering.

Most people think it’s worth shelling out the extra cash for a color display if the budget allows it as well. This permits your images to “pop” and makes them easier to view under the sun’s bright rays.

Larger screen size also increases your ease of reading! The right display for you all comes down to your preferences. Some you can even read for fish finding without taking off your fishing sunglasses.


Anglers benefit greatly from GPS, charts, and waypoints. Finding your way back home or to good fishing spots in unfamiliar waters can be a worthwhile addition. Using your fish finder to map structure and cover is a great way to return to where fish school and feed.


You want a fish finder that is battery-friendly. While many people don’t use standard batteries, you’ll need a decent rechargeable 12V battery before going out on the lake.

Scanning & Imaging Methods

Side-imaging fish finder allows scanning wider areas and seeing schools in detail. Yet, the side-scan sonar won’t produce effective imaging in deep waters.

This is where a down-imaging sonar comes in and uses a single transducer emitting a powerful sound wave and is better for monitoring deep water rather than a wide cone angle to find fish.

Water Resistance

When using a fish finder on an open boat, water resistance is a major consideration. Check the product’s specifications for JIS or IPX scores. A system with an IPX rating of 4 is water-resistant, but that won’t be enough if you’re on a kayak.

What’s the bottom line?

In testing, it was a delight to use these fish finders with GPS units to see which came out as the overall best option.

While great down imaging can make or break the decision, it can be easily overwhelmed by features and thus cost. For years, Garmin fish finders have built on the top of their other devices, and again, they came out on top here.

The Garmin Striker Plus 4 with Dual-Beam transducer again tops the charts as the right fish finder for many average anglers. It is portable and can be used in many fishing situations. While it has a small screen compared to many alternatives, it is easy to read no matter what data you display. (Find the Best Beginner Fly Fishing Kit)

You can even use the device in split-screen for your waypoints and scanning at the same time. The Garmin Striker must be the best affordable fish finder for use in kayaks or when doing some ice fishing.
