Fish Finder Buying Guide

Top 6 Best Fish Finders 2020: Tested Reviews & Guide 19

So, read on this buying guide and rest assured you will be buying the best one from the above reviewed best fish finders 2020 list.

How Does Fish Finders Work?

Fish finders are actually a SONAR device. It stands for Sound Navigation And Ranging, which means that fish finders use sound waves. So, let us explain the working and mechanism of a sonar device in fish finders.

A sonar device is a simple device that will send through the water pulses of sound waves. These pulses will go under the water, will hit some object or the bottom of the sea/ river, and return back. Once the pulses return, the sonar device will send more pulses and keep the process going until it develops a fair picture.

When pulses return, the fish finder will try to figure out multiple things. It will calculate what was the object that the sound pulses hit. Moreover, it will figure out the depth of the seabed, the weight of the object that pulses hit, and also how many objects were there under your boat.

A fish finder will read these signals from a sonar device and translate them in digital signals over a screen. It points fishes and other objects through a separate image, so you never confuse between both. The working of a fish finder is, thus, similar to those bats and dolphins use.

Why Should You Buy The Best Fish Finder?

Why Should You Buy The Best Fish Finder -

The best fish finder for kayak will prove a very useful tool when you are fishing. Gone are the days when fishermen spent the whole day in search of fishes and sometimes had to return empty-handed. Now, this simple yet effective device will allow you to locate fishes without wasting more time.

So, here we will look at some of the best ways a fish finder will help you.

  • It will help you locate fishes and other objects in the water without going down physically. The sound waves will make a complete picture for you.
  • You can even target specific species of fishes and find if they are available nearby.
  • A fish finder will also help you to locate the bait.
  • It will also help you to find the depth of the water and type of surface without a need to look at yourself. Thus, a single sound wave will solve all of your issues.

When we look at all these uses of a fish finder, we find it to be a useful device. If you want to save your time, focus on fish catching instead of wasting time on locating fishes, then a fish finder is a useful device for you.

How To Buy The Best Fish Finder 2020 & What Factors & Features To Look For?

How To Buy The Best Fish Finder & What Factors & Features To Look For -

If you are looking for the best fish finder, you must know about several crucial factors. These factors will decide whether your model is the best one or needs some improvement. So, let us look into the different features.


The core part of your fish finder device is the transducer. It is the same part that will send and receive the sound waves and perform all calculations. You must look into the cone angle, type of installation, and frequency of your transducer.


When it comes to the display of your fish finder, it covers color, contrast, and the detail of the image. You must also look at the image of fish. Some of them feature LED display screens and show clear colored pics, while others just show black and white objects. The latest versions come with a clear and large display to show you the most results.

Screen resolution

The greater resolution will enable you to see a clearer picture of fishes. You can even zoom in to look at objects in a better way. So, you must select the best resolution for you.


The frequency of your sonar device is also a critical feature. Higher frequency devices will give you a clear picture of even small fishes. At low frequency, you can get a better idea about larger fishes. However, people now prefer devices with dual frequencies.

Side imaging vs. down imaging

You can also call it the cone angle. Those with down imaging have a smaller cone angle and will cover less area. However, they give you more and accurate details of the water. Side imaging devices will cover a greater area due to their larger cone angle. However, their accuracy is slightly lower than down imaging.

Portable vs. Fixed

Unlike many electronics where we prefer portable devices, we will recommend you a fixed fish finder. Use portable only if you fish less often or using a rented boat. The mounted models are more common because you can fix them at a place and get better quality. Due to their popularity, you will find all the latest features in a fixed fish finder.


There is no better application of GPS than in fish finders. A device with GPS will allow you to locate the land back from your journey. It will help you find the ponds nearby. You can even mark fish hotspots using your GPS and start from the same place the next day.

What Are The Available Types Of Fish Finder?

What Are The Available Types Of Fish Finder -

Well, there were many different types of fish finders in the past. The technologies were also quite a lot, but most of them are now obsolete in terms of use. Nowadays, we use the following three types of fish finders in a great number.

  • Kayak Fish Finders
  • Portable Fishfinders
  • Fishfinders for Ice Fishing

If you have a rented boat, then the need for a portable fish finder increases. In cases when you have a small boat, you may also show interest in the best fish finder for small boats.

Ice Fishing Fish Finders

When you are fishing under the ice, you need a special instrument to help you find the fish. Since you will drop your bait in a vertical position, you have more interest in looking for the fishes under your bait.

Mechanical fishers might break a lot and will require more repair in these extreme conditions. So, you need the best fish finders with a digital flasher. A 2D sonar will help you a lot in this case.

How To Find Fish Using A Fish Finder?

Most fish finders come with the basic SONAR technology, which they use to locate fishes. As we explained earlier that they use sound pulses to locate objects. Once the pulses return, the fish finder judges whether the hit object was seabed, plants, stone, or fish.

Once the fish finder starts to work, it will send sound pulses in the water. In most cases, the pulses it sends has a speed of 1 mile per second. Once the pulses return, you can see the fishes on your screen.

One of the types is Fish icons where fishes have IDs and will tell you how many fishes are there. However, arch technology is much better as it will help you find about the size of fishes. Send the waves and wait for the display to get the best results.

How To Use The Best Fish Finders? Tips To Use The Best Way!

How To Use The Best Fish Finders Tips To Use The Best Way -

A fish finder is often fit in your kayak or boat unless it is not a portable one. The fish finder will send sonar waves in the water after some time. At each stage, it will record some data and display the results to you. However, there are some tips that will allow you to get the best results.

Look For Feeding Formations

If the fishes have gathered at some point to look for feeding, that is the best time to go fishing. You can find this by looking if larger fishes are near small fishes. In this case, the large ones are surely looking for food. They will surely bite the bait that you send and will become your prey.

Use The Latest Tech

There is no benefit in using the best fish finder if you are using old tech. Modern fish finders will give you so many features to make your fishing easy and fast. So, instead of sticking to the traditional black and white models, it is better to upgrade and make stuff easier.

Use the zoom feature

If you have got the latest version, it may show a zoom-in feature quite often. Many people don’t know the use and will ignore it. However, it proves very useful when you are fishing. For instance, you might think of several small fishes as if it is a single large fish. The zoom feature will clear your confusion by showing a clear picture.

Track more area

Most people stick to a single area for the whole day. They just wait for fishes to come and trap. However, it is always better to track more areas and look for areas that have more fishes. It increases your chance of catching more fishes.

Monitor the temp

When you are fishing in a professional way, then you must not ignore the water temp. Most fishes have a suitable water temp and will not go to other parts. So, you must know this fact and target your efforts towards fruitful resources.

Find feeding fishes

When the fishes are moving freely, they are looking for food to feed themselves. You have more chances for the fish to bite the bait. On the other hand, if fishes are hiding near a rock, they will less likely bite your bait. So, you must try on moving fishes as they increase your chances of catching more fishes.
