Why Invest in a Kayaking Fish Finder?

Fish finders are devices used to seek and identify fish. As a result, Fish finders give you the options of seeing aqua structure, viewing the depth, locations, and water temperature.

Let’s see what the other advantages of having a fish finder are:

  • High-end fish finders come with GPS which shows the location of the kayak as it moves on water. This is particularly useful if you are trying to reach a hot fishing spot and also in marking your current location if you find a good spot.
  • It can be used in various water conditions, for example when raining, under ice fishing, on lakes, saltwater, and even aggressive rivers.
  • A temperature gauge is often including in the fish finder that is handy to improve your fishing results, especially during the spawning time. Some fish species are very sensitive to water temperature and knowing this will improve your fishing results.
  • It will help you to find the structure, such as weed beds, timber, and holes as well as flat areas like sand flats.
  • They are user-friendly and have easy to understand icons. Fish finders have evolved a lot over the last decade to the benefit of the angler.

Things to Consider Before Buying a Fish Finder for Kayaks

Let me take a wild guess, you have already thought that you going to miss some must-have feature as your budget is pretty tight.

Here are some crucial factors that you should consider for a good quality Fish Finders for Kayaks. Some of these criteria are must-haves and some are optional. But consider all of these features based on your own personal requirements.

Remember – the best fish finder for a commercial fisherman’s boat is not the same as the best for a kayaker. Pick the option that is right for you.

Display

The display is the second most important feature of a fish finder. It contains the screen and the user interface.

A high resolution and sharp contrast make everything easier to see and read, which also helps as the screen can be viewed in full daylight. So undoubtedly, it’s a crucial feature. 

Screen Size

Screens are available in anything from 3 inch to 6 inches (or even larger for the boat based models). For a kayaker where space is a premium then you want to get a fish finder where the display is as small as you can handle while still seeing everything clearly.

If you need reading glasses but don’t intend on taking these with you when kayaking then keep this is mind when selecting a screen size.

Resolution

The resolution is defined is the number of pixels on each side of the screen with the larger number dictating how clear the image is. This can be anything from 240 x 160 up to 640 x 640. The smaller resolution displays are significantly cheaper but are not as clear.

Don’t be tricked by the low price tag of a low resolution display if you can’t actually see any fish or structure on it while paddling up the river.

GPS

Yeah, it knows it’s an advanced feature and hard to find in a small budget. But the good news is some manufacturers have designed the fish finder with a GPS at a very reasonable price. So look for whether the fish finder you choose has this feature.

This is particular useful if you are going in an ocean kayak out to sea. Knowing exactly where you are and where you are going is both a safety feature and allows you to fish in hot spots that are indistinguishable from the water surface.

GPS can also be useful if you are travelling long distances in your kayak up a winding river and need to find your isolated campsite.

Transducer Type

The transducer sends out the signals of sonar that find the fish. This feature allows you to mount on your kayak. With upgraded fish finders, you can use several cone angles operating to send the signals to go deep and wide.

The transducer is the most important feature of your fish finder. It provides the accuracy and information that is shown on your display. Selecting the correct transducer for your water depth is critical for high performance of the entire unit.

Signal Frequency

The frequency of a fish finder is normally one of either 50, 83, 192, 200, or 455 kHz.

Generally the shallower the water you are fishing in the higher the frequency you will require.

No matter if the frequency is low as 50 kHz, which may offer a vast angle for the signal. Good news is nowadays fish finders brands offer several frequencies so that you can easily switch from low and high frequency.

There are also 4 different types of frequency including High, Low, Dual, and CHIRP.

High Frequency

High frequency signals are most suited for shallow water fishing locations. This gives a lot of information at close distances but doesn’t penetrate the water as far.

Low Frequency

Low frequency signals are best suited for deep water as they can penetrate the water more easily, but they don’t carry as much information so the image isn’t as crisp and clear as high frequency.

Dual Frequency

Dual frequency fish finders allow you to switch between High and Low Frequency depending on what you need at any point in time. They are the best of both worlds.

CHIRP

CHIRP stands from Compressed High Intensity Radar Pulse. It is the most superior technology for transducers that changes between frequencies to provide the highest accuracy regardless of the water depth.

If budget is no question, then always go with a CHIRP fish finder.

Cone Angle

One of the key criteria you will see in any fish finder’s specifications is the cone angle. This can be anywhere from 10 degrees to 65 degrees which is a very wide range.

Transducers have been designed to send out multiple beams simultaneously.

Fish Alarm

Some fish finders come with alarms that ring out when they find fish. This is called a fish alarm. If you are fishing in a location that is full of large healthy fish then this can be extremely annoying, however if you are desperate for even the smell of a fish then I would recommend turning your fish alarm on.

Water Depth

The depth that you are fishing at does change the type of fish finder that you need. If you are fishing in deep holes or in the ocean then you will need a down-imaging sonar. This will give the highest accuracy at depth.

If you are only going to be fishing in shallow lakes or rivers then a side-imaging fish finder is a better option. This will show more water underneath your kayak and help you to find the best locations to cast a lure.

Water Temperature

Some fish finders will display the weater temperature in the top corner. This is particularly useful when fishing for bass around their spawning season. Many recreational fish species change their behaviour and location based on the water tempearture.

Having this feature in your fish finder and knowing how your target species behaves at different temperatures can be the difference between a day paddling and a day catching fish.

Power Source

If you are looking at the large, high-end fish finders then you will notice they are generally hooked into the boat’s electrics and are powered directly from the 12V batteries. Obviously this is not suitable for a kayak when space and weight are at a premium.

You will want to select a fish finder that uses internal, rechargeable or replaceable batteries.

Kayak Mounting

A key consideration is how you are going to mount the display and the transducer of your fish finder onto your kayak. Some high-end fishing kayaks come with their own transducer mounting locations.

Some kayaks also feature scupper holes that allow you to pass the transducer through the hull. Make sure you understand how you are going to mount your fish finder before making a purchase.

You might also want to pick a fish finder that suits your kayak. Old Town and Ocean Kayaks have been designed to fit Humminbird Transducers, while Hobie and Wilderness Systems kayaks are better suited for Lowrance mounts.

If you don’t have any dedicated space for a transducer mount and a display mount, then you might want to consider a portable fish finder with a castable transducer. These often Bluetooth to your smartphone. Just toss the transducer into the water and see what’s underneath you.

Finally, you can mount your transducer to the transom either at the rear or stern of your kayak. This can make them vulnerable to damage from any accidental collisions.

Decision Time: Which One Should You Pick?

If you are in a tight budget and thinking that you have to buy a low-quality fish finder, then you might be mistaken. Even with a limited budget, you can get some awesome gear.

Let’s discuss some of them now.

10 Best Fish Finders for Kayaks

Here are my reviews of the top 10 of the best fish finders that you can find on the market at the moment.

Check this out:

1. Garmin Striker 4 GPS Fish Finder for Kayaks – Best Fish Finder GPS Combo

The Garmin Striker 4 is my favorite fish finder. It is extremely cost effective but has all of the features that you would expect from a high end model.

The CIRP sonar gives detailed representations of structure and fish. The GPS means that you won’t get lost or miss your favorite fishing spot.

It is suitable for ice fishing or vertical jigging.

With this fish finder you can go anywhere and do anything.

My Impressions

Such a great fish finder!

My first impression of the Striker 4 was very positive. There are just so many features packed into this small package. The wide options of display sizes available with the best of the best transducers means that you will see everything under your fishing kayak even at deep water depths.

The display also shows the water temperature which is a must have for bass anglers over the spawning season.

Oh did I forget to say that its Water rating is IPX7? This means that it can handle 1 meter of water depth for up to 30 minutes. This is not classified as waterproof – don’t drop it overboard, but it can handle rain or splashes from your paddle.

Now let’s talk about the overall design.

View your sonar data and information in the classic flasher format with the Display 1.9 x 2.9 inches; 3.5 inches diagonal.

Plus, it includes CHIRP transducer, tilt/swivel mount, and trolling mounting cable. But one negative is for top-performance CHIRP; you have to buy a GT8/GT15 transducer separately.

Key Features

It offers a keyed interface with amazing buttons. One definite advantage is this device is extremely easy to use. The user interface is simple and robust.

What I Like Most?

  • Easy to install.
  • Waypoint map.

What Could Be Better?

  • Not so good in shallow water.

I am certainly intrigued by the iBobber. It is a favorite fishing gift every time Christmas or Black Friday come around. It is cheaper altentive then some of the multi-hundred dollar devices.

It doesn’t require any permanent installation or mounting, which makes it extremely simple to use and easy to install.

I personally don’t like the app’s display as much – it is more like a fishing game with icons rather than a data based view of the river bed.

iBobber Fish Finder for Kayaking

Key Features

The Bluetooth syncs up to 100 feet away, so you get the advantage of seeing at a distance, rather than just what is directly under your kayak. This is particularly useful if you don’t get close enough to structure.

  • The smallest portable fish finder on the market.
  • This is also one of he most cost effective fish finding options as it doesn’t come with a dedicated display.

Humminbird are one of the top manufacturers in the fish finding and GPS industry. If you are looking for an option that is cheaper than the HELIX model, then consider the PiranhaMAX.

The dual beam sonar means that you can switc between a narrow and wide beam depending on the water depth and amount of detail you want to identify fish, structure, and contours.

The display is also on a swivel mount so you can see it front on no matter where it is mounted on your kayak.

There are also accessories available such as an attachable waterproof case that means you can still use your fish finder when it is raining or you capsize your kayak.

My Impressions

I love the user interface of all Humminbird designs and the PiranhaMAX is no exception.

This is a great entry level fish finder for the casual kayaking angler. It shows great detail of the river bed including fish and structure, but it doesn’t come with advanced technologies like CHIRP transducers or GPS and contour mapping.

Key Features

The 4.3 inch color LCD display comes with 272 x 480 pixel resolution.

It is IPX7 water resistant which means it can handle splashes and rain without damage but it won’t survive drowning.

Dual beam sonar to switch between narrow and wide cone angle and high and low frequency signal.

What I Like Most?

  • The dual sonar allows you to change the cone angle depending on your depth.
  • This device contains a lot of features for its price tag but doesn’t have all the bells and whistles.

  • It doesn’t include GPS so make sure you aren’t going long distances away from your base camp.

Significantly less expensive then the other options is the Lucky Handled Portable Fishing Sonar.

This has the ability for the kayak angler to see the water depth, bottom coposition.

Surprisingly it can read up to 328 feet deep, and comes with a 25 ft cable so you can float the transducer from the kayak, even when you are moving at up to 5 mph.

It is powered by 4 x AAA batteries.

8. Raymarine Dragonfly 4 Pro

The Dragonfly uses advanced wide-spectrum CHIRP technology that allows the unit to interpret more detail, image structure, and target more fish with almost unmatched clarity.

This unit is powered by 12V DC, so it is only suited for large enough fishing kayaks that can handle an external power source.

It is IPX6 and IPX7 waterproof.

Also available in premium alternatives that include GPS chartplotter technology.

9. HawkEye Fishtrax Fish Finder

  • Sonar up to 240 depth
  • Trollable, Boat Mountable, Floatable, Portable
  • Fish Alarm
  • Made in USA
Bestseller No. 1
HawkEye Fishtrax 1C Fish Finder with HD Color Virtuview Display

  • VirtuView HD color display with LED Backlight produces a glare-free view for excellent readability
  • Sonar sensor is trollable, boat mountable, and floatable to achieve unmatched, go anywhere, portability

The Fishtrac by Hawkeye is for beginner anglers who are more interested in affordability and ease of use than accuracy.

This hand held model comes in 3 options and includes an audible fish alarm, backlight display for night time viewing, and shows key fishing data like water depth and water temperature.

Personally, for the same price you can get a much higher quality option from Lowrance or Humminbird – I wouldn’t recommend this fish finder for a kayak fisherman.

10. Venterior Portable Fish Finder

  • 200 kHz sonar frequency
  • Accurate to 328 feet
  • 2 Year Warranty
  • 4-5 Hour Battery Life (4 x AAA batteries)

  • No need to drill hole in your boat hull to install the sensor any more. Two small holes on the wireless sensor allow you to tether with your fishing line and cast it onto water as far as you want.

Last on our list if the Venterior Portable Fish finder. Like the previous two options this model is focus more on affordability than accuracy.

It comes with a 25 foot long cable, so you can toss the transducer into the water and see the water depth, temperature, and depth of fish as you pass by.

It also has an audble fish alarm to tell you when a fish swims past.

As with the previous fish finder I would recommend an entry-level Humminbird, Garmin, or Lowrance over the Venterior.

Frequently Asked Questions

How do you mount a fish finder to a kayak?

There are several different ways for mounting a fish finder to a kayak – this can be transom mounted at the stern or rear. You can also get portable transducers that you can throw into the water and Bluetooth to your smart phone. Some kayaks are also designed with scupper holes where you can pass the transducer through the hull.

Are fish finders waterproof?

Most fish finders are water resistance, meaning they can handle some splashes, however they are not waterproof and cannot be submerged. There are waterproof jackets that are available for some fish finders that make them more robust.

Wrapping up

Undoubtedly finding the best fish finder for kayaks in a tight budget is quite difficult. And honestly speaking, you might be compromising with some handful features. 

In this case, you can trust this fish finder list. I put endless effort to pick the best one within a reasonable budget. Each of the fish finders has entered the list due to their top-grade performance.
