Buying guide


Buying the best kayak fish finder is a daunting task, and customers can often times end up feeling baffled about which model they should pick. The market’s filled with good-quality units. If you’re just beginning to look for a unit yourself, you might want to check out the following buying guide we’ve put together in order to help you correlate your needs with the features you might be looking for. Here’s what you should know.

1.Deeper Wireless Sonar

Screen size and resolution

The display is important both in the case of regular fish finders and in the case of kayak units. The screen size has a lot to say when it comes to accurately visualizing what’s going on in the water. Some models have the screen size of ancient mobile phones, which is why those might not do too much in matters of efficiency. The display resolution also has a say, as does a backlit screen.


Desirable features

With kayak fish finders, frequency does not matter a whole deal. Sure, it’s important, as is the wattage, but it isn’t a deal-breaker as in the case of classic fish finders. Desirable features include built-in UniMaps and internal GPS receivers, as well as Down Imaging capabilities.

For your consideration, we’ve compiled a list of the three units that are most acclaimed on the market today. All of the following models have gathered some of the best fish finder reviews, coming from American and international customers alike. They’re well-known for their excellent performance and for being reasonably affordable.



When you go kayak fishing, there are many things you need to take into consideration. For starters, you will need to bear in mind that any weight you add to the kayak will affect its ability to go fast. To avoid such problems, when it comes to picking a high-quality fish finder for your kayak, get one that is portable.

Handheld units are designed to be less bulky than their counterparts. Of course, the moment you choose to go for a more compact unit, you may be starting to wonder whether you are sacrificing performance for the sake of portability.

That brings us to a very delicate, but important issue. Your bet should be on a unit made by a reputable company that does not reduce overall performance for the sake of portability. That being said, you should get a compact unit that is still as good as bulky sonars, without encumbering your kayak with unnecessary weight.


Dual frequency

You should ignore such a feature if you want a fish finder that can see virtually everywhere. There is one spot, in particular, that is overlooked, sometimes even by more seasoned anglers, and that is the area right underneath the boat. You can solve such issues by getting yourself a model with dual frequency.

There is a standard advice among anglers when you feel like you are losing the fish because it goes under your boat. This opinion refers to the necessity of changing the frequency. No matter how far or close the fish is, you should be able to follow it with the help of your fish finder, and this is where dual-frequency operation comes into play.

Don’t be surprised to see prominent fishing gear companies making fish finders advertising such a feature as one of their essential selling points. It comes in handy while you are kayak fishing and you will have no regrets about purchasing such a unit.

Depth range

While you are searching for a high-quality fish finder, don’t forget about other important aspects, such as the ability to determine depth range for the schools of fish while on the move. The further the sonar on your fish finder can go, the more accurate you will be in predicting how the schools of fish will move around.

Being a good angler is not only about the expertise you have; it is also about what kind of gear you are using. A high-quality fish finder should be able to determine depth range, and it should be capable of reaching as far as possible. With this kind of information on your side, you will have more success catching plenty of fish, and, of course, brag about it once you return home.


Determining the shape and consistency of the bottom

A body of water is entirely an exciting place underneath its surface. Experienced anglers know very well that fish can hide under rocks, inside underwater bushes and other formations, and the information you get on you fish finder may be misleading, as a result. What may feel like a particular target can be well protected and you will just experience the disappointment of going home empty-handed.

You don’t have to allow such things to happen to you. Get yourself a fish finder capable of delivering information on how the bottom of the water body looks like. There are all kinds of fish finders on the market, and some are more accurate than others when it comes to such data.

Models with top-notch performance can tell you a great deal about the shape of the bottom, the consistency, and hardness, as well as thermoclines and other similar aspects that will help you achieve the highest accuracy in finding the fish you are after.

Although it is expected that such models are more expensive than others, as long as you manage to strike a balance between the useful features offered and the budget you have at your disposal, you will not be disappointed with your choice.



It may sound redundant to mention this particular aspect, but the truth is not all fishfinders on the market are entirely waterproof. As expected, when you go fishing, you will have to deal with a lot of sloshing, and it is not difficult to imagine that droplets of water will end up on your sonar, too.

Sonars have delicate mechanisms built-in, such as GPS sensors, that help them identify fish targets in the water. However, these mechanisms should be well protected against water, or they may deteriorate rather fast.

In case it is not possible for you to get a model that is as waterproof as you would like it to be, a good bet would be to search for a model that is as cheap as it gets while still offering some waterproof capabilities. Otherwise, just make sure that your sonar is located somewhere it cannot be easily affected.


Can it be mounted?

A question you should ask when you’re shopping for a fish finder is whether the unit can be mounted on your kayak or not. It is preferable that you get a model that comes with such capabilities, as there will be many situations when you will not both your hands-free.

Another aspect to keep in mind when you evaluate and compare different models on the market is how much mounting space the unit will take. Don’t forget that for kayak fishing, you need to make sure that all the gear you purchase must take up as little space as possible.

This is the number one reason why bulky sonars are never a good option for kayaks. Any extra weight will influence how fast the kayak can go, and there may also be a problem when you need to find enough space to accommodate the mounting area for the fish finder.

Bear in mind that the sonar should be placed somewhere you can easily see it. A fishing adventure should be your chance to unwind and have fun, so forget about fish finders that will only add an unnecessary level of challenge.


Simple operation

There is a saying that warns about devices that come equipped with too many buttons and features. The more of these you have on your fish finder, the likelihood of something going wrong and breaking increases exponentially. That being said, the next piece of advice refers to the fact that you should get a fish finder with simple operation.

A few critical features were mentioned earlier, and we will not go back to that. Simple operation is, however, more than just having few buttons to use. It is also about having a unit with an easy to figure out interface. Although in this day and age, we are very much used to advanced technology, that doesn’t mean that a fish finder should be challenging to use.

You need a unit that is responsive and also ensures that you will quickly find what you are looking for. The information has to be displayed in a way that is not difficult to understand. Also, when setting up the unit, the installation and all the necessary information required for the GPS and the like, should be easy, too.


With the quick advancement of technology, it is nothing unusual for our day-by-day devices to receive updates on a regular basis. Fish finders are not that different, and, if you want to spend money on a model that won’t disappoint you, in the long run, you should go for one for which the manufacturer includes updates.

These updates concern the software used for operating the GPS, most of the time, but that doesn’t mean that you have no use for them. A competitive unit can make the difference between a successful fishing trip and major disappointments, so pay attention to the fine print. If the manufacturer doesn’t shy away from offering updates, that is a good unit for you.


Adaptability to night and day conditions

When fishing in less than ideal light conditions, you may not be able to see all the information you want. That means that it helps to have a fish finder with a screen that is adaptable for night and day conditions. A backlit model can make a difference, as you will be able to read the displayed information even in the dark.

Also, a screen that offers wide viewing angles and does not present a washed out display when the sun is up in the sky is more useful than one that does not follow some quality standards. While aspects like screen resolution and size are essential, such extras are never bad to have.

Pick a model that has all the crucial components crafted to the highest standards possible. This way, you will be purchasing the fish finder that is capable of maximizing your chances to catch as much fish as you want while on fishing trips.





What battery should I use for a kayak fish finder?

Kayaks are, by definition, cramped places where you cannot accommodate bulky sonars. That means that you cannot allow a bulky battery to power up your kayak fish finder, either. The battery used for such fish finders should be able to pack a lot of power in a compact case. Sealed lead acid batteries are one option. The main benefit ensured by them is that they are cheap. 12v 10amp batteries of the kind will keep your fish finder powered up. However, they tend to lose power in bad weather. Lithium batteries, on the other hand, are lightweight and more reliable. Also, they can be recharged.


Does a kayak fish finder have to be waterproof?

It is preferable that your kayak fish finder is waterproof. There is little room inside a kayak, and that means that you have to use the space wisely. Consequently, you will not be able to place the fish finder just anywhere, and it is preferable that its spot will not allow too much water to slosh over it. However, if you ever went kayak fishing, you know that such a thing is not possible. As a result, it is more desirable than not to have a waterproof unit. Like the rest of your gear, it should be able to repel water to the best of its abilities.


What screen size is right for a kayak fish finder?

Again, you need to take into consideration the little space you have at your disposal when kayak fishing. While you may feel tempted to think that a larger screen size should be your choice, the problem with such sonars is that they become too bulky and they are not as easy to use as you may like. That is while a fish finder with a screen of 3 or 4 inches is enough for kayak fishing. Of course, you should always take your preferences into account, and, if you cannot see a smaller screen, opt for a slightly larger one.


Is a GPS-enabled fish finder better?

There are pros and cons for using a GPS-enabled fish finder, and we will show them right away, hoping that the information provided will help you make an educated choice. Fishfinders with incorporated GPS are an excellent choice when you go fishing on a body of water that is unfamiliar. You will be supplied with accurate readings, and you will not have to worry that the unknown factor will affect your results. On the other hand, if you go kayak fishing in well-known areas that are not very wide, you may choose to save up a little money and get a model without GPS.




How to install a kayak fish finder


Each fish finder usually comes accompanied by information on how to mount it, and it is best to start from there. Mounting a fish finder on a kayak can present a lot of conveniences because you will be able to keep both hands free to see about your fishing, while reading relevant information on the screen of your sonar.

A few steps are required, nonetheless, for a successful installation, and if you manage to get all of them right, you should have, at the end of your endeavor, a working fish finder safely mounted on your kayak.


Grab the necessary tools and materials

Mounting a fish finder on your kayak requires a bit of work, but it’s not rocket science. You need the right tools and materials, and then you are good to go. Here are all you should have at hand.

For tools, make sure you have a power drill and the necessary bits for drilling holes. A screwdriver and wire stripper should not be amiss, either. Have a soldering iron nearby, and a hair dryer for the last touches, in case you don’t have a specialized heat gun.

Regarding materials, make sure you have the entire mounting kit needed for the fish finder you want to install. Keep the instructions delivered upon purchase next to you, as you will need them as you progress. Fitting, tubing, solder, electrical tape and zip ties should be on your list, too.

Installing the transducer

The first step involves mounting the transducer. Take the kayak and flip it over. During this stage, you need to identify an area that is very flat. It is highly recommended to install the transducer in such an area, and particularly in a stronger part of the hull so that it does not allow flexing, something that can lead to the transducer becoming loose.

Make sure to pass the wiring from the transducer through the scupper. Then screw the plate into the hull for maximum stability. Make use of the hardware delivered with the fish finder, and follow the instructions offered by the manufacturer.

Fitting the cable that comes from the transducer through the hull is a difficult portion of this step, but once you secure it in place, things will get easier. Bear in mind that this should go through the hatch under the seat area, as this is how the cable to reach the upper part of the kayak. When doing this, make sure to keep the kayak on one side for smooth operation.


Installing the display

Now that the transducer is in place, you will have to connect the display. First things first, make sure that you pick a good spot for the screen. It should be somewhere it is easy to read. When drilling holes to pass through all the wires, make sure that you don’t use bits larger than necessary. As long as you can push the plugs through with ease, there’s nothing more you need.

Create a grommet with the use of a rubber stopper. This will help keep your unit stable and also waterproof from below. Mounting the base of your unit onto this grommet should be easy, and you can push the grommet in its place with the use of a screwdriver. If you can, secure the base in place using nuts and bolts.


Installing the battery

Some degree of preparation is needed during this step. Connect all the power cables to the battery, and cut any excess. Unlike transducer cables that should not be cut as they may end up malfunctioning, you will need a more precise approach to installing the battery.

Once you have everything connected, it is the right time to ensure that all the connections will remain in place. Use the soldering iron and solder. This way, the links will be protected, and you won’t experience any malfunctions when you use the fish finder.

Attach the battery holder and screw everything in tightly. It is preferable that the fuse is protected inside the hull, and kept away from water, to avoid corrosion in the long run.

In the end, make sure to secure all the cables and wires in place with wire ties, and clean everything. This way, you will make sure that you did an excellent job, and your fish finder will work precisely as intended.
