Fish Finder Review 2021 – Which sounder should I buy for my Kayak, tinnie or boat. With kayak fishing and boating booming, this has become a very common question. However, this question is generally answered by your available budget, fishing style and features required. This guide will walk you through the available features and price ranges to help you decide.

Fish Finder options based on tier

We generally separate sounder fish finders into 3 separate categories entry-level, mid-tier and high end. Which have a contrasting price point and set of features designed for different applications.

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

  • Lowrance Hook Reveal
  • Garmin striker plus
  • Garmin echoMAP Plus series

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

  • Lowrance elite FS

Downscan vs traditional 2D Sonar

When buying a sounder make sure you give time to consider what features that you require. Understanding the difference in features, capability and price is key for making the right choice, For example, 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 2021. This image really represents the difference between side imaging, down imaging and traditional 2D sonar. Each view telling 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.

Lowrance Hook Reveal fish finder review 2021


These new fish finders just hit the market in Jan 2020 and are a successor to the very popular Hook 2 range. These sounders are considered entry-level tier with an affordable price point but a nice set of features. With powerful performance with fish-finding tools including, Autotuning Sonar, DownScan Imaging and now FishReveal technology. These makes fish easier to see by combining CHIRP sonar and DownScan Imaging on one screen. Navigating is simple with the GPS Plotter, which makes route, trail and waypoint navigation is easy.

The Lowrance Hook Reveal is available in the following options

  • Hook Reveal 5 inch with GPS Plotter, Maps, DownScan and deep water performance
  • Hook Reveal 7 inch with GPS Plotter, Maps, DownScan, SideScan and deep water performance
  • Hook Reveal 9 inch with GPS Plotter, Maps, DownScan, SideScan and deep water performance

These units are one of the most affordable and one of the most popular sounders used for kayaks and smaller boats. Lowrance has marketed this as the worlds 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, sd card slot for software updates and chart upgrades. The main difference between the Hook 2s and the Hook reveals is the new fish reveal technology. This is where they have 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

For me, the downside to these sounders is 2 major things. No touch screen, having to use buttons to reposition maps, zooming and general features is so frustrating. Also quite poor readings in certain situations. when moving at a reasonably slow speed you get a lot of interference and poor readings and the readings can also be quite poor really shallow water, deep water and certainly. 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 ti12, HDS Live, Simard, go and NSS EVO 3s.

In terms of usage, it has very easy Navigation, 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 hook reveals 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. The downside is the readings are just as not accurate. That being said if you fishing from a kayak or a tinnie maybe you don’t need readings in deep waters when moving around. If you are new to boating and kayaking these would make an excellent option.

Garmin Striker Vivid fish finder review 2021

Garmin Striker

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 structure 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 optimise 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

Simrad NSS Evo3 fish finder review 2021

Simrad NSS Evo3

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.

Best fish finder for your kayak

When buying a sounder for a kayak you need to give a lot of thought to the size of the sounder ( considering many yaks have a small workable area ). The mounting system, battery location and transducer installation.

If you have a Hobie Kayak then Lowrance is a preferred brand choice. That’s because most Hobie kayak models come out of the factory Lowrance ready. Lowrance ready mounting brackets underneath the kayak so you can easily attach the transducer that comes with your sounder to the mounting brackets. This means no drilling during installation simply unscrew, attach run the cables through and screw back on.

Some terrific options include

  • Lowrance hook reveal 5 and 7 inch models
  • Garmin Striker Vivid 5 and 7 inch models
  • Lowrance Elite FS 7 inch model

Lowrance Hook 2 Fish Finder Review 2021 ( superseded by Fish Reveal in May 2020 )

Lowrance Hook2 Fish Finder Review

Released towards the end of 2017 the Hook 2 range are your entry-level sounders. Lowrance suggests that these are targeted at casual anglers. They are the most affordable starting from as low as $100 and by far the easiest to use. They do still provide a good level of functionality without needing to change settings or complication. These are very good units for beginners. Everything is pre-setup and ready to use on the water.

These are very intuitive with the simple one-thumb operation, and the ability to switch between down scan, side scan and GPS quickly. The fish finders are available in SplitShot, and TripleShot providing CHIRP, DownScan and StructureScan. As with all products you get what you pay for. These compared to high-end fish finders are missing things such as touch screen, chart plotting, and have limited range, and not as accurate reading. They are however great value for money and will do an excellent job telling you the water depth, temperature, and will give basic readings of schools of fish, bait and structure.

The Lowrance Hook 2 come in the following options

  • Lowrance Hook² 4x + Bullet Transducer
  • Lowrance Hook² 4x + GPS + Bullet Transducer
  • Lowrance Hook² 5x + SplitShot Transducer
  • Lowrance Hook² 5x + GPS + SplitShot Transducer
  • Lowrance Hook² 7x + GPS + TripleShot Transducer
  • Lowrance Hook² 9x + GPS + TripleShot Transducer

They also come available in 12 inches would be unpractical for a kayak.


Lowrance fishfinder options in 2021

Lowrance has a great range of options for both boats and kayaks. As the image below shows the Hook reveal would fit in the entry-level category, elite FS in the mid-level and HDS live 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.

Lowrance Sounders available in 2021


Installing a sounder or fish finder on your kayak or Hobie

If you’re like me you may need assistance having your sounder installed. There are some great local centres that 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. A good example of what can be seen in the embedded video below.
