Fish Finder Review 2024 – Which sounder should I buy

Fish Finder Review 2024 – Which sounder should I buy for my Kayak, tinnie or boat? With kayak fishing and boating booming, this has become a common question. However, this question is generally answered by your available budget, fishing style and features required. Sounders play a pivotal role on your vessel to help you find fish, understand the depths, navigating, identify reefs and so much more. Those who understand how to use their sounder will often have high catch rates for a variety of species and systems. This guide will walk you through the available sounders on the market and identify their features and price ranges to help you make an informed decision to suit your vessel, fishing style and budget.

Fish Finder options based on tier

Buying a fish finder can be a complex task, as there are many different brands, sizes and features to choose from. There will be some confusing terminology to get familiar with and you also need to know how to mount and power them. Some with touch screens, some with anti-glare screens and some with different pairing options. In Australia, the most common brands are Lowrance, Garmin, Humminbird, Simrad, Furuno, Raymarine and a few others. To make the process easier for you let’s separate fish finders into 3 categories ( 1. entry-level, 2. mid-tier and 3. high end ). These 3 different price tiers offer buyers a different set of features designed for different applications and budgets.

Entry-level fish finder recommendations are generally priced between $400 and $1,000

Lowrance Eagle ( Has recently superseded Lowrance Hook Reveal )
Garmin Striker plus
Simrad Cruise

Mid-tier fish finder recommendations are generally priced between $1,000 and $1,500

Garmin EchoMAP UHD2

Sounder Marine Electronic Modes

Sounders come with different types of transducer options that omit a ping at various frequencies and visually represent the returns in different ways. The table below will highlight the differences between traditional scanning vs down and side imaging technologies. Generally, a single shot transducer will be smaller in size and only capable of traditional views and mapping, whilst triple-shot transducers can support all 3 modes plus navigation. Some sounders will also have transducer upgrade options to get wider beams or stringer frequencies to improve the coverage area and reading accuracy. But let’s start with the 3 basic modes.

Traditional Sonar
Side Scan ( Also known as Side Imaging and SideVu )
Down Scan ( also known as Down Imagining and DownVu )

What is traditional sonar scan

This is the typical view that Sounders have used for many years. Omitting a beam at different frequencies and getting a 2D reading. This is what a traditional scan looks like. This is still one of the most used screens which identifies fish, bait and depth really well.

What is Side Scan

Side Imaging provides an underwater view of the bottom and sides of the boat a bit like a live Aerial photograph. Generally a max distance of 75 meters on either side of the boat. Different brands call these different things Side Scan (Lowrance), SideVu (Garmin) & Side Imaging (Humminbird). This technology works by omitting sonar beams in a cone shape spread over a wide angle. Side Imaging transducers usually operate between 100kHz and 500kHz. When using Side Scan it’s a good idea to move slowly under 6 knots to allow the sounder processor to keep up and provide accurate and detailed readings.

What is Down Scan

Down Scan provides a live photo-like image of the bottom and structure below the Boat. The technology name is different amongst brands Lowrance calls this DownScan, Garmin calls it DownVü whilst Humminbird calls it Down Imaging.
Down Imaging is generally set at a frequency of 800 kHz (45°) and 455khz (75°). The best images come when moving slower and in shallow waters

Traditional 2D sonar shows a radius under your boat whilst Downscan gives a clearer view with more detail straight down of what is underneath you. Both can be very useful, but it’s great to have both.

Down imaging vs Side imaging

Fish Finder Review 2024. This image represents the difference between side imaging, down imaging and traditional 2D sonar. Each view tells a different story. Down scan has a narrow beam pointing down giving you a clear view of what’s directly under you, Traditional gives a general view of a radius to the sides and underneath you and side imaging casts a beam out to each side of the boat giving you a lot more detail of fish and structure in the distances.

Best entry level low-cost fish finder and sounder for 2024

Entry level sounders are very popular and sell in massive volumes. It may be your first sounder, it may be that you need a sounder on a budget or it may be for a smaller vessel. Whatever the reason there are some great options. Entry-level sounders generally come at a price point under $1,000. They have come a very long way and today provide an amazing and intuitive experience. They are often quite simple to learn. The downsides to entry-level sounders are smaller transducers for weaker readings, often not having a touch screen, fewer mounting and pairing options, lower resolution screens, slower processor power and often smaller screen size. That bein said in today’s age we have some amazing options at an affordable price point.

Lowrance Eagle fish finder review ( superseded Hook Reveal in 2024 )

New for 2024 is the Lowrance Eagle has superseded the very popular Hook Reveals ( released in Jan 2020 and the previous generation the Hook 2 range ). These entry-level sounders with an affordable price point but a nice set of features. Very intuitive to use and has been heavily marketed as the easiest sounder to use on the planet. The newer model has improved screen resolution, more colours, enhanced transducer, twist lock connectors and increased processing power. It includes fish-finding tools including, Autotuning Sonar, DownScan Imaging and now FishReveal technology. These make fish easier to see by combining CHIRP sonar and DownScan Imaging on one screen. Navigating is simple with the GPS Plotter, which makes the route, trail and waypoint navigation easy.

Available in 4, 5, 7 and 9 inch screen options. Transducer options include bullet, split, triple and HDI

Key Features

Enhanced SplitShot HD and TripleShot HD transducers*
Autotuning sonar provides optimal settings from the start
Detailed C-MAP charting featuring Genesis Live* (dependent on the region)
Enhanced IPS screen visible from all angles, even while wearing polarized sunglasses
New reliable twist-lock connector system for easy installation in any boat or kayak
SD card slot for software updates, Genesis Live recording, and charting add-ons*
FishReveal mode to help separate fish from structure*
Increase contrast and visibility with all-new imaging color palettes*

These units are one of the most popular sounder choices for kayaks and small boats. Lowrance has marketed this as the world’s easiest sounder to operate with set and forget technology meaning this sounder requires little to no manual configuration and automatically updates the settings depending on the system and depth that you are fishing. You can go into the settings and adjust the colours, depth, chirp and sensitivity but we typically don’t see too many people playing with the settings of these units. For the price, you pay it offers a really good range of features including traditional scan, down scan, side scan, maps, plotter, and SD card slot for software updates and chart upgrades. The improved fish reveal technology with new colours and overlays on the downscan setting with a lot more colours, defined shapes, and clarity to help you identify fish easily. These improvements allow you to easily identify the difference between fish, bait, and structure.

At this affordable price point, there are features that you won’t get including No touch screen, having to use buttons to reposition maps, zooming and general features. At times poor readings in very shallow and very deep waters. When moving at fast speeds you can get interference and poor readings. That’s because the transducer is much smaller and casts out a weaker signal and the returns are not as accurate as your higher-end models like the elite FS, HDS Pro, Simard, go and NSS EVO 3s.

In terms of usage, it has very easy Navigation, the home button select button pages allow you to move between modes easily. You can also easily add and customise split screens, Enable plotter, Mark waypoints and change basic system settings and controls. In summary, at that entry-level space, the Eagles are a really good choice. You get a lot of features for that lower price point. The screen is sharp, has great colours, and easy to flick between the scanning modes and is easy to manage waypoints. Excellent option for kayaks and small boats of those new to fishing or on a budget.

Garmin Striker Vivid fish finder review 2024

In 2019 Garmin released the first of their STRIKER series. A cut down version of the Echomap series at an affordable price point. The key difference being that these trimmed down versions had no maps or data storage. However the take up on these sounders was excellent and now Garmin has made some updates to this series adding a transducer update, and a new colour scheme.

All the Striker devices come with a high sensitivity receiver so fishers can not only see fish and structures below the boat but can also quickly mark their favourite spots. When trolling the GPS will update position once per second giving you an extremely accurate positional report for waypoints, dialling in the exact trolling speed and optimising lure presentation. You can also share waypoint data across Striker Plus units as well as the new Echomap Plus series.

Features 7 vivid colour options for sonar to easily identify fish and obstacles
Built-in GT20 transducer gives you both Garmin’s CHIRP traditional and ClearVü sonar
Maneuverable tilt/swivel mounting bracket
Highly sensitive GPS for navigation and find waypoints
Easily mark your fishing spots, create routes and keep track of your speed
Built-in Quickdraw contour mapping to spot any obstacles or sandbanks

Best high end fish finders and sounder for 2024

Lowrance HDS Pro review 2024 ( superseded HDS Live )

The HDS Live was superseded in December 2022 by the HDS Pro which will make its way onto the shelves on most fishing retailers by Q1 2023. The HDS Live had a shelf life of 4 years released in 2019 and superseded what was the popular HDS Carbon series. It was one of the first sounders on the market to have Active imaging, Fish Reveal technology which is now found in many sounders today like the Elite FS, and Hook Reveal range ). You can also buy upgraded hardware to enable features like Structure Scan and live sight. ( to see things happening in real-time, like dropping your lures dropping, or fish chasing your lures ). All your major retailers by default will sell this unit with the Active 3-1 transducer and CMAP.

The new HDS Pro has upgraded active target 2 live sonar and now includes fish reveal on side scan and active target imaging, which are impressive updates.

When the unit was released its major selling points were

Clear high-resolution touch screen, great colours,
quad-core fast processor,
excellent readings and a good mix of auto and manual settings,
Wi-Fi to pair with other units and apps,
a whole range of frequencies and chirp settings 50khz through to 800khz which is basically the shape and direction of the beam to give you different readings. Most commonly using 83khz to 200khz
analogue and HDMI ports on the bigger units,
multiple SD card slots,
and large memory to store up to 3000 waypoints and 100 routes.
Wireless remotes
Pair multiple units. ( might have them at different parts of the boat or use one for maps and the other to find fish ).

They come in 4 sizes 9, 10, 12 & 16 inch screens

Intuitive

These units are so intuitive. Easy settings and easy clear apps to navigate your way around almost like a smartphone. Easy Navigation, a simple operating system which has icons and titles making it very easy to understand. It’s very simple to set up Split Screens, Change colours and much more.

WayPoints

Easy to create instant waypoints
Easy to add your waypoints
Easy to navigate around waypoints using maps and waypoint screen
Storage and copy backup of your waypoints

Auto vs manual.

The auto does a great job at auto-adjusting to where you’re fishing. So certain settings will automatically change depending on the depth and range. That being said you can easily adjust the frequency, gain, depth, chirp settings to get clearer readings. Now this can work really well if your find clutter on the screen ( weedy areas like WPort ) or if the readings are a bit weak.

Settings heaps of stuff here you can customise, I generally only change things such as miles/kilometres, feet/meters. Stuff along those lines.

For the most part, the unit does an excellent job in auto for traditional and downscan, however, you may want to consider manually changing the range when using side scan.

High chirp ( amazing detail for shallow water ) Low Chirp low-frequency wide beam great for deep water.

Low CHIRP or 50kHz—Lower frequency means higher power for deep-water fishing.
Medium CHIRP or 83kHz—Specifically designed to give the widest coverage area, 83 kHz is ideal for watching a bait under the transducer in shallow water.
High CHIRP or 200kHz—Higher frequencies display a higher resolution image making it easy to discern fish from structure or structure from the bottom.
455kHz—Built into StructureScan HD and SpotlightScan, 455kHz allows for scanning of a large range with picture-like detail.
800kHz—Also built into StructureScan HD and SpotlightScan, 800kHz yields less range but even higher resolution detail than 455kHz.

Cost

7 inch $1,749 on special at BCF with 3-1 active transducer + CMAP
9 inch $3,399 on special at BCF with 3-1 active transducer + CMAP
12 inch $4,599 on special at BCF with 3-1 active transducer + CMAP
16inch $TBC at BCF with 3-1 active transducer + CMAP

Gotchas

Power consumption – This is higher than some competitors like the Garmin UHD series and Simrad Go series.

2-year warranty 1 year on the transducer

It’s a great mid-range sounder. It’s one of the most popular sounders on the market and has been since its release in 2019. It has a high resolution, fast processor, great colours, excellent readings and a good mix of auto and manual settings. Its also fairly priced. This is a great unit for those with runabout boats or those with kayaks who want the best of the breed. Including active imaging, which provides greater detail without sacrificing range or having to change frequencies. There’s also active Imaging 3D enhancement, FishReveal, LiveSight Forward & Down – giving you a much more comprehensive view of fish activity. You can even integrate the sounder with other units, live radars, google maps, weather updates, music, and smartphones.

Simrad NSS Evo3 fish finder review 2024

SIMRAD was founded in 1946, and is now part of the Navico group which includes Lowrance. Simrad is world-class leader in high-end fishing electronics. The Evo3 released in 2017 supersedes the Evo2 which was released in 2014 which was a terrific unit.

The NSS7 evo3 complements the larger screen sizes of the NSS evo3S range with a high-definition 7-inch display that delivers a big-picture view of high-detail, C-MAP US Enhanced inland and coastal charts, Radar, Active Imaging Sonar, and more. NSS evo3 has integrated wireless connectivity and an HDMI out, allowing you to mirror your display to your smartphone, tablet, or an onboard TV.

SolarMAX IPS display with extreme viewing angles; viewable through polarized sunglasses
Preloaded, high-detail C-MAP US Enhanced inland and coastal charts
Full operation via touchscreen or keypad controls
Touchscreen control of sonar, radar, autopilot and accessories
Industry-standard connectivity to engines, sound systems and more
Automatic routing support, plus easy trip planning with TripIntel
Flexible installation with low-profile flush mount or bracket mount options

Now for those who don’t know Simrad and Lowrance are owned brands of the parent company Navico, with the Lowrance brand covering the low and mid-end sounders range and Simrad being their high-end sounders. When you think of low-end sounders like the Lowrance hook reveals there are a few things that are really frustrating including poor transducer readings, Non Touch Screen and low resolutions.

However, The NSSO EVO3 is the complete opposite.

High-quality wide beam transducer which will give you really accurate readings to identify fish and structure.
You can do that across more depths, and motor along a little bit faster
Dual processor, High-resolution touch screen available in sizes from 7 inches to 16 inch
Outstanding definition and colour settings
It does all the basic features exceptionally well, like a plotter, charts, multi-screen
There’s also some really advanced stuff in here that I’ve never used like autopilot and halo radar integration

There is a lot of familiarity in operating system and dashboard across all Simrad and Lowrance units, going back to the main screen allows you to easily switch between traditional, down scan, side scan and split screens. And making your own custom split screens is very easy. Some Favourite features are the quick toggle scroll to zoom in on maps, zoom in on schools of fish

If you are in the market of buying a sounder you need to understand there are some massive fundamental differences between the low, mid and high-end sounders. The low and mid-end units are almost what I would classify as a set and forget and what I mean by that is the settings are usually left on auto and that means that the depth and readings will automatically adjust depending on where you are fishing.

These higher-end units require a lot of user manual control and tweaking that’s why it’s imperative you get familiar with the features and how to control the settings. In particular, you will find that you are constantly changing the gain, frequency, sensitivity, noise reduction and depth settings all depending on the location that you fishing. And you can easily do that using the touch screen and making minor adjustments like this. However, you will find that your constantly tweaking these settings and for some people that can get a tad annoying.

Now, these sounders will be out of the price range for many anglers, but id always stress sometimes spending a tiny bit more and the features and quality will last much longer and improve your experience on the water.

Garmin GPSMAP 8400 and 8600 series fish finder review 2024

The Garmin GPSMAP series of sounders is very impressive. Accurate and detailed images and a fast processor that keeps up with the highest demand of SideVu and DownVu. We have done water testing using a Garmin 8410SXV with GT54UHD Transducer and the results were very impressive. Bright colours, clear readings and some amazing images when using downvu and sidevu.

Best fish finder for your kayak

When buying a kayak sounder, you need to consider the size of your kayak, the transducer mounting options, battery location and installation. Kayaks generally have small spaces and having a sounder that will complement your fishing as opposed to getting in the way is critical. There are many good brands, models and sizes available but do keep in mind that many Hobie kayaks come built Lowrance-ready with mounting brackets underneath the kayak so you can easily insert the transducer and cabling. This means no drilling, no 3rd party mounting systems and cleaner cable configuration. Generally, a sounder between 5 and 7 inches is ideal for a kayak however small kayaks may benefit from the smaller 4-inch options and larger yaks like a Pro Angler 14 can get away with 9-inch screens.

In our many years on the water kayak fishing with sounders, we believe the options below make great choices.

Some terrific options include

Lowrance Eagle 4, 5 and 7-inch models ( Superseded Lowrance hook reveal 5 and 7-inch models )
Garmin Striker Vivid 4, 5 and 7-inch models
Lowrance Elite FS 7 & 9-inch model
Humminbird Helix 5, 7 and 8-inch models
Garmin UHD 2 ( 55, 65 and 75 models )
Simrad Go 7-inch model
Humminbird Pirhna Max

Installing a sounder or fish finder on your kayak or Hobie

If you’re like me you may need assistance having your sounder installed. Some great local centres will do this for you at a small fee. This would include AWS in Geelong and SL Hobie. Please call those centres directly to arrange a time to have your sounder fitted. You can install different branded sounders but the installation of the transducer may be a little more complicated and require some custom parts and installation.

Lowrance fishfinder options in 2024

Lowrance has a great range of options for both boats and kayaks. As the image below shows the Hook Reveal fits in the entry-level category, Elite FS in the mid-level and HDS Pro into the high-end category. Many of these models have been refreshed with the hook reveal and elite FS getting a decent facelift towards the end of 2020 and HDS Pro being a new release in 2023.
