Best Fish Finders According To Experts

Before we dive into the best fish finders out there, i want to tell you about their story. Origins of fishing have been practiced for a very long time, it dates back to 10,000 years. Many people who live near lakes, rivers, and seas have had to do some fishing to get their daily meals. In the past, people didn’t use fish finders or any kind of device that would help them get the fish.

They had to use bare hands to catch a fish, it sounds impossible I know, but they had no other option. Nowadays there are a lot of devices that will help you get ”your daily meal”.

A lot of people do this activity for different reasons; some take it as a hobby while others do it as a full-time job. Some people consider fishing a boring and an old man’s sport, but fishing is more than that, if you never tried it you can’t truly give your honest opinion about this topic, any way you should check it out because it can be anything from a relaxing to a very intense experience, and that’s the beauty of it.

Now, when it comes to fish finders, I can say that the invention of fish finders is a technological blessing because it gives you the ability to locate and catch fish much more easily and turns the fishing experience into an enjoyable hobby. There are plenty of methods for fishing, but the best so far is the fish finder.

In 1948, The Furuno brothers (owners of a small marine electrical company in a small port of Japan) invented this amazing new technology that took the fishing to a new level. They started developing a fish finder using scrap materials and repeated this experiment many times. It didn’t work as they expected, however, gradual improvement of the equipment leads to successfully finding fish.

Nowadays, the technology has been advanced much more, in every aspect, of course in fishing too. Today you have a lot of fish finders out there, even the least expensive fish finders will provide accurate depth information in graphic and they cost around $100, but if you think that you are ready for a whole another level, a top-quality recreational one can cost up to $1000.

What you have to do is choose the right and affordable fish finder for you, and do not forget that you should choose wisely depending on your purpose.

Based on my research I will try to provide you general tips on how to find the best fish finder and show you some fish finder reviews. Here are my top picks that will deliver great qualities.

What Is A Fish Finder?

A fish finder

Now, when it comes to fish finders, I can say that the invention of fish finders is a technological blessing because it gives you the ability to locate and catch fish much more easily and turns the fishing experience into an enjoyable hobby. Real fishers know that fishing is not as easy as it sounds but with the help of a fish finder, it surely becomes easier.

There are many successful fishermen out there who use their gut to locate and catch fish, however, using a Fish Finder helps you a lot. An electrical impulse from a transmitter is converted into a sound wave by an underwater transducer (hydrophone) and sent into the water. When the waves strike something such as a fish, it reflects and displays the size, and shape of the object. This is how a Fish Finder works.

Shopping for a new fish finder can be a hard task, especially for the experienced angler, there are dozens of models coming up every year, and each has its place for the right use. There are a large number of fish finders out therefrom at any budget and any skill level. If you are asking: ”Should I get a Fish Finder?” , ” Is a Fish Finder worth it ?” If you want to fish, then yes, it is the right type of device for you.

What To Look In A Fish Finder

Of course, there are some things that you need to know before buying a Fish Finder, this depends more on the intended purpose of the device. Fishing right? Yes, I know that, but what I am trying to say is that if you are a beginner and you just want to go out with some friends and catch a fish once in a while you don’t need a $1000 Fish Finder with high-end features. On the other hand, If you go fishing more frequently and do it as a business or as an experienced enthusiast then you might want to get a more advanced model. Either way, it is better to be informed before making a choice. Some fish finders can also be used as a depth finder, which lets you see the depth of where fish is. Most modern ones have a depth finder built-in, so this shouldn’t be a huge problem.

Screen Resolution

Before buying a Fish Finder you should always consider looking for the display you want. The more pixels you have, the more detail the display can put out. If you want to spare money then you can aim for lower resolutions. 240 x 160 is the minimum you will need if you go a little lower I’m afraid that you will have some trouble catching the fish. However, try to buy the best display quality you can afford because it will pay off. Most modern devices have a LCD screen, so you shouldn’t worry about it too much.

Water Resistance

About the water resistance, you should always check the JIS or IPX ratings. If the rating is less then 4, then that might cause you some trouble. On the other hand, a rating of 8 can go underwater for a considerable period. You need to know that the rating makes all the difference. Don’t forget to take a look at the rating before you hit the lakes.


GPS is another important thing for Fish Finding. With the GPS you can record the depth, and it increases your safety, (especially during worst fishing times). And of course, only with a map on the Fish Finder, you can find and mark the hotspots you are looking for. Besides, the GPS systems will also allow you to mark favorite fishing places, and even check dangerous areas in the water.


Having a better CHIRP means that you can identify the fish easier. CHIRP is the sonar technology that fish finders employ. It uses bursts of different frequencies to let the transducer vibrate at a low frequency.CHIRP will deliver better target separation and give you images with deep water penetration.


You should always pay attention to the price. Some products are pretty expensive and still have bad quality. That’s why you should always research before buying the product.

Portable or Fixed

This one depends on your fishing style. If you do a lot of fishing in other people’s boats or rental ones, then a portable unit is what you need. If you own a boat or a kayak, then you should consider a fixed Fish Finder.


These are a must to every Fish Finder. They send out and receive sonar waves. In other words, the transducer is the heart of a fishfinder system. It receives the echoes after it sends the sound waves. These work with any kind of boat, you just need to install it right.

Fishing Spots

Before buying one, make sure you know where you are going to fish. For example, If you are going to fish on shallow water, you don’t need a high-end fish finders because a cheap portable fish finder will do just well.  On the other hand, if you plan to fish on deep waters, then you will need a more advanced one.
