Considering your requirement we're presenting all the best fish finder reviews through this site. After you finish reading this article you will be such an expert that you will want to sleep and kiss your fish like my friend here.

Getting to the point, we know how important it is for every angler to find the equipment that fits them the best. Therefore we have chosen ten (10) of the best Fish Finders in the market that will take your experience to the next level. Since we know not only professional anglers will read this article we would like to give a little overview.

fish finder reviews

Fish finders are useful equipment that allow the angler to see a graphic representation of what’s underneath the boat to identify or not the presence of fish.

Before you go to any seller and order one you have to ask yourself what kind of Fish Finder you need: standalone, chartplotter combo or network? If you have a small boat, your budget is limited, you are just starting on the angler world and don’t want to risk so much, or you just like to go as old school as you can, the standalone version is the best for you.

It will fulfill the main propose of the equipment which is to let you see what’s beneath the boat, and whenever you want to go bigger is always possible to connect a GPS sensor later to convert it into a chartplotter combo.

Then we ask ourselves what benefits can give us a chartplotter combo? A combo unit is useful for the ones that have a mid-size boat or bigger. It uses GPS as navigation system to reach the fishing grounds, also offers you the option to split the screen so you can view the chartplotter and the fishfinder.

The installation of a transducer can convert your chartplotter into a combo unit as well. Read more about the transducer in our “Buying Guide” at the bottom. At last but not least the fully Networked system are suggested for all major suppliers because allow huge range of data sources as are radar, video, satellite radio, raster and vector GPS charts.

Usually this type of equipment allows Bluetooth/WiFi connections and is compatible with Android and IOs. In this same range we can consider the multiple-display network systems that are the perfect match for medium-sized to large vessels.

Now that we have a clear panorama on at least the main three categories of fish finders we can start with our list.

Best fish finder guide

How To Choose The Best Fish Finder

To choose the best fish finder you've to consider some points while going through fish finder reviews. The features that need to be considered have been given below. 

1. Device Screen

It’s a widespread fact that LCD Displays consist of so called "Pixels" which are nothing more than the smallest controllable elements of a picture on a physical display device. The more pixels are being stacked up on each other (vertical orientation) the higher is the depth oft the resolution.

The amount of Pixels in horizontal orientation determines the life cycle of an Object on the screen before it gets swiped out of the view by gestures supported by modern Technologies like Touchscreens.

A high density of Pixels per square inch result in a better detail of Images and a general improved 'feel' oft the Screen. It also allows you to recognize better what’s below you and the split-screen images are also of higher quality. A decent amount of Pixels, screen resolution and screen size make it easier for you to spot air bladders of smaller fishes, fishes on the ground and target individual fishes.

Another important factor is the contrast that your display offers. It has to be sharp and exact for a cleanless identification of your target fish and its separation from mud. All in one you should consider aiming for a device with a good display resolution.

2. Diagonal measure of screen size

A widescreen display has the ability to display more meaningful information at once. For example you can locate your elements individually or you can use it to run and display the different programs your device offers at once (e.g. GPS, Radar and other Sensor signals).

3. Electricity

The performance of a fish finder is determined by the amount of watts(RMS) it handles. A good sight in not so clear water or a peak into depths require a higher amount of energy. Generally a 500-watt fish finder should be able to execute most standard operations well.

It’s recommended for blue water anglers to aim for a device of 1000 watts or even more while inland fishermen are fine with a 200 watt device.

A high frequency of the transducer plays a key-role in determining the fineness of detail resolutions which is important in order to avoid background noises and clearance of view when moving with rapid boats. However it’s sight into depths is worse compared to a transducer operating on lower frequencies.

If you’re on a moving boat then aim for a high frequency, if you are planning to have insights into deep waters then go for a lower one. Anglers that are active in shallow-water normally pick frequencies of 200 kHz,400 kHz or 800 kHz.

For waters with a depth of 150 Meters it’s recommended to pick a Frequency in the range between 200 kHz and 800 kHz. For deeper waters you’ll do better with a Frequency somewhere between 50 kHz and 80 kHz.

4. CHIRP and Broadband fish finders

Broadband fish finders are a modern trend on the market they are also known as Compressed High Intensity Radar Pulse, shorty CHIRP. The difference is that these fish finders don’t operate statically on one or two frequencies like the traditional fish finders.

It sends out a signal on a specific Frequency and swings it up to another predetermined frequency. A CHIRP fish finder differs in its performance from traditional fish finders by having less peak power.

However the advantage of its wide-band frequency technology allows it to transmit long during pulses and therefore put up to 50 times more energy into a water. Because of the application of scientific algorithms like digital pattern matching and signal processing a CHIRP device offers outstanding screen resolution and intelligent target detection. Instead of spotting masses of fishes you’re able to locate individual fishes within its groups.

A depth range of 300-500 Meter is easily attainable with these broadband devices which also offer highest sounder technologies.

Most of these sounder technologies include dual-transceivers which permit asynchronous and independent operations on high and low frequencies and a certain level of freedom to customization. Each transceiver is in to your needs.

The same rules for frequencies apply here as with conventional fish finders: The lower the frequency the better the sight into depths. Also it requires less energy which leads to less generated noise by the device, also known as "water whispering". The fishes are targeted without disturbance.

Higher frequencies should be used for mid-water depths.

5. Orientation

It’s important to identify which features you really need. There are devices with high frequency transducers that allow sight into different angles like side, straight down or a 360-degree View.

There are many variants of features which often lead to a confusion in the selection of necessary attributes. For example an inland angler who’s mainly looking for fishes in shallow lakes won’t have any use for a feature that allows you to stare down 2500 Meters.

Avoiding devices with that feature will most of the time save the fisher some money. Instead he should focus on a horizontal-based view. Nowadays you can identify devices that suit your needs by its names like “StructureScan HD” or “CHIRP DownVision”.

6. Transducers

High frequency transducers produce shorter wavelengths but create more instances of them per second. Thus you can visualize more Objects in closer range to the device.

In our case it’ll mean that we can see more fishes within a certain depth. Therefore will a high frequency transducer mainly be necessary if your primary need is a clean resolution and not insight into the depths of deep water.

For instance a 200kHz transducer will grant you a sight into no more than 200 Meters. For optimal performance it’s recommended to pick 800 kHz or 455 kHz transducers. An optimal device for lake anglers.

Lower frequency transducers produce longer waves but create fewer instances per second than the high frequency transducers. They offer less clearance and quality of detail but they contain more energy and allow to scout into bigger depths.

Dual frequency transducers contain elements to send and receive multiple frequencies at the same time (asynchronously). There are also Dual beam and QuadraBeam transducers which allow not only multiple frequencies but also different directions at the same time.

Low frequencies commonly use wide beams that help you to spot large objects for example caves or hiding places for fishes. High frequencies often operate with beams that spot the fishes very near to the boat. Beware of using plastic thru-hull housings on a wooden boat.

Wood has the property to absorb water and swell which can lead to a cracking oft he housing. If you’re using an aluminum boat then avoid using a bronze thru-hull housings as an interaction between aluminum and bronze will damage the aluminum hull and the bronze housing, especially in salty water.

Normally a fish finder that is shaped for small-boat, freshwater angler comes with a transducer, mostly a transom-mount type. However a lot of people purchase the transducer separately.

Types of Transducer

There are few types of transducers you might want to know about: Thru-hull, Transom-mount, In-hull, trolling Motor.


Thru-hull is the most challenging one to install though it provides the best quality of signal. It’s being used mostly by sailboats. A thru-hull transducer includes a depth and temperature sensor and normally also a speed paddle wheel.


A Transom-Mount has an adjustable bracket that is screwed or bolted to a transom where the transducer hangs below and behind the hull. The installation is more simple but it can suffer more often from turbulent water flow.


An In-hull transducer doesn’t require a direct water contact. It’s glued with silicone or epoxy to the inside of the hull. Unlike other transducers it doesn’t work on cored or steel hulls but on stable fiberglass. Just like the transom-mount transducers In-hull transducers are popular on trailer boats.

Trolling Motor

A trolling motor is clamped to the outside or permanently installed inside the propeller hub of the trolling motor. Some models include a built-in 200 kHz transducer that suits a lot of popular fish finders.

Let's get some fish finder reviews so that you have the best product or gear for fishing at best.
