The act of fishing may not be considered by many to be an extreme sport, but the process of buying equipment certainly is. Going into a fishing shop without knowing what kayak fishing gear you want will feel like skydiving without a parachute.

Fish finders for kayaks come in a million styles, with many brands, and a ton of features that can very quickly become overwhelming. Knowing precisely what you want and for what purpose will shorten your time browsing by hours.

A lot of them use the same technology as each other but in different-sized packages. Learning your preferences will make life a lot easier.

Of course, most anglers won’t need the more expensive fish finders, which can cost over $4000. To catch fish from a kayak, a cheap fish finder will usually do the trick.

Even with a basic kayak fish finder, you can still pick out shoals of fish swimming beneath the surface with relative ease.

8 Best Kayak Fish Finders

Picking your next kayak fish finder will depend on a large number of factors; first and foremost are budget and the size of your fishing kayak.

It is best to save for exactly the right fish finder you want or need rather than cheaping out on a lesser model. You also can’t go buying a fish finder that won’t fit on your kayak dashboard.

Take a look at this list, and I’m sure I will have listed something for every budget and need.

1. Lowrance Elite FS 7


Lowrance is a name that is well known in the fish finder game. They produce models such as the Lowrance Hook Reveal and of course, this, the very well-loved Lowrance Elite FS 7.

Lowrance comes with their own C-Maps preinstalled on their fish finder display. They allow you to work your way around 8,900 lakes in the US with your GPS-enabled fish finder. A perfect, topological map with contours and sizing helps you navigate around your favorite fishing spots.

This upgraded version of the Hook Reveal features a touch screen, networking capabilities with multiple other fish finders for kayaks, and HD display quality.

A Buying Guide for the Best Kayak Fish Finder

When you first see someone using kayak fish finders on their trips, it is a revelation. The detail and insight into what is under the water completely change the game, no longer do you have to rely on thrown bait and guesswork to know where the next big catch is.

The problem lies with actually trying to find a fish finder for kayaks. They are designed for everything from shore fishing all the way up to deep sea trawlers, so making sure you have something appropriate is important.

Thankfully, I’m the fish finder nerd you need. Let me walk you through some of the more important elements of buying the best fish finder.


For kayak anglers, this is a serious element to take into consideration. A kayak has a very limited amount of space usually and you can easily overload your deck with battery packs and large fish finders.

A lot of fish finders are made for much bigger vessels, so ensure you have both the mounting space and cockpit area to handle it. Of course, you’ll want the biggest screen you can handle, but make sure you don’t overestimate your kayak.


Not every kayak comes with the rails to accommodate a fish finder, so you’ll need to make sure you can mount it without it getting knocked into the water by your swinging paddle blades.

Fish slime and excess water can make your deck slippy, and the last thing you want is your expensive equipment down with the very fish you were trying to catch.

Good portability means you can move your fish finder around as you need it, making sure it isn’t in the way and can be tucked where you need it safely. Models such as the interior can even be worn around the neck for ultimate portability.

GPS Technology

This is a feature that really separates the good fish finder from the great. Being able to not only find yourself on a lake map but also be able to be tracking speed and location whilst doing so is a fantastic boon whilst out and about.

GPS tracking often comes with a custom map covering that allows you to pinpoint favorite locations or points of interest for later trips.

Method of Imaging

Imaging comes in two main types, and each has its own benefits and downfalls. Choosing the right one for you is important.

Side Imaging

best kayak fish finders

This method throws a sonar around your vessel, picking up a scan of either side. It gives a wide range of top-down information perfect for fishing from the side of your boat.

Down Imaging

This gives a detailed picture of the bottom of the water, picking out fish and features in a 2D image. The scan quality ranges from picking out basic shapes to being able to specifically identify fish, branches, bait, and many other underwater items.


Displays can vary from highly detailed, color-coded imaging all the way down to simple LED displays of basic shapes under the water. Maps can be wildly detailed with beautiful high-definition contour lines and details that will guide you around your local water.

Deciding how much detail you want will affect the pricing of your unit drastically. The main thing to endure is that the display is able to be seen in bright light without too much glare and is completely waterproof. It doesn’t matter how careful you are, you’re going to get wet.

Extra Features

When shopping for the best fish finder for kayak fishing, you will notice a lot of them advertise so many extra features that promise to make your next trip incredibly easy. Options like a fishing log, map sharing, multi-interface networking, and fish identification make their lists long and complicated.

The best fish finder for you will only include what you need. If you are the more avid angler, then getting yourself a fish finder that can log every trip you have made and chart your most successful spots is a great choice. For the casual fisher, simply grab yourself some equipment that shows you where the big boys are.

Extra features will cost you extra dollars, so weigh up what you need to what you can afford.

Deep Water

Take care to find a fish finder that will scan deep enough for the lake you are in. They all come with power ratings that correlate to the depth they can scan to.

If you are only planning on paddling around shallow water can save some cash for extra features by cutting on depth power, but if you want to go out into the open ocean, you’re going to need the watts to match.

Saltwater vs. Freshwater

Saltwater has higher organism content and a lot more noise than freshwater, so will often need certain settings and higher power. Make sure you are buying a unit for the water you need. Some freshwater units will not have the capability to work in saltwater.

Frequently Asked Fish Finder Questions

I’ll answer the questions you would only end up fishing around the internet for later.

How Do You Power Kayak Fish Finders?

They can be powered in a multitude of ways, but the most common method is with a waterproof battery box stored in the hull of your craft. The battery box needs to be kept dry and safe. Some smaller units are able to run without a battery box and can power themselves for a few hours on small batteries.

How Long Will a Battery Run on a Fish Finder?

When using a 12v battery on a fish finder, you can expect to achieve about 50 hours from a regular 2amp fish finder.

Will Any Fish Finder Work With Any Kayak?

They will all work provided you have the space for both the power and the actual unit itself. There is no point in getting a finder that won’t fit inside your craft. Make sure you have the gear track and rails to hold it securely whilst you paddle or motor around.

If I May Cast My Line

Kayak fishing is a wonderful way to enjoy a lake. It is serene and calm but punctuated with small pockets of high-octane hunting. You can while away the hours on a lake with a friend or alone just take in the beauty of the surrounding nature.

Fish finders are an excellent piece of equipment for anyone looking to take their hunting to the next level. They are able to give spectacular views of the water around and beneath the boat, highlighting both the water bed and the surrounding environment.

Using sonar and GPS combos, detailed images can be displayed right there in the comfort of your kayak.

In recent years, the best fish finder for kayaks has become incredibly technological. They are able to display GPS maps, depth, and side imaging area displays. Wireless fish finders can interact with multiple electronic units, including other fish finders, your motor, and even drones for the super dedicated.

Getting yourself a fish finder just improves your chances of landing that next big fish. (You can also take a look at the best kayak fishing net available on the market). You can claim all the glory of a record catch with the help of one excellent bit of kit. I guarantee once you give them a try, you’ll never look back.
