Because the technology never stands still and there are regular changes. Nevertheless, the following table offers to find the Best Fish Finder quickly and easily. There you will find the best available equipment with the most important details at a glance.

What is a Fish Finder?

what is a fish finder

The Fish Finder uses the technology of sonar. This was originally invented during World War II to find enemy submarines. The device sends for ultrasonic waves, which move at more than one kilometer per second through the water.

Whenever they hit something harder than water, they are reflected and received from a station again on sonar. Based on the time it takes for the individual waves can then distance determined very accurately. In this way, anglers know how deep the water among them. In addition, however, other irregularities are determined.

The fish finder prepares the information on a graph, which is usually displayed on the integrated display. However, this is not obvious where exactly are fish, but only approximate values concerning the established irregularities. Larger accumulations of dense objects on the seabed may, for example, be an indication of a shoal of fish.

Benefits of a Fish Finder

A fish finder is principally useful for any angler, but even in the event of normal shipping good service. Nearly every ship is now equipped with a depth sounder to measure the water depth permanently. This ensures that no one runs unintentionally from fish. But anglers naturally want primarily interesting places to find fish.

Benefits of a Fish-Finder

Who can estimate the information of his fish finder properly, so he needs a powerful tool in hand? Although the device can’t tell exactly how many fish are there and what types of fish are available. But it takes depending on the model very reliable so-called hot spots, i.e., places where large quantities of fish are present than in other places in a lake or the sea.

Today’s devices done their quite simple operation by convincing way by. You do not necessarily hang in the water, but can be operated easily from the boat. Another important step is to filter out your boat as well as the surrounding air. That done many fish finder automatically at some other models, the user must take some action for a good result, but the Best Fish Finder even correctly assesses the results.

The way of a Fish Finder works are interesting not only for fishermen but also for divers. This can determine the practical equipment before a dive, how deep is a body of water and whether it any obstacles or even dangers.

What kinds of fish finders are available there?

What kinds of fish finders

Fish Finder acts both as a mobile and stationary solutions. Mobile Fish Finder can be easily taken anywhere, so they are ready for immediate use without any complicated installation. This benefits all who are traveling on several different boats. If you own a mobile fish finder, it’s not necessary to setup your device install to all boat.

Useful is also for those who like me, who do not own a boat and so they can’t mount stationary fish finder. The biggest disadvantage of mobile Fish Finder is the less precision. Since it does not operate directly in the water, the emitted sound waves are already disturbed by the air and the boat. The results are indeed still helpful, but not as accurate as a stationary sonar.

Hard on Inappropriate boat Fish Finder achieve significantly better results. One reason is that they usually have a higher power. You can send up to 4,000 watts, whereas mobile echo sounders are rarely more than 2,400 watts. The stronger the signal, the deeper can spend a reliable sonar values. Only with stationary solutions are therefore measurements up to 1,000 meters or even more possible. So if you like in deeper water fishing, comes to the installation of a suitably equipped fish finder hardly around.

Differences between individual fish finders, there are also at the frequency to be emitted with the sound waves. More is not always better here. While indeed high-frequency waves provide more details, achieve low frequencies deeper regions in the water. For shallow water of frequency is 200 kHz, therefore, useful, but in deeper water supply equipment with 50 kHz significantly better results.

But a sensible solution for All-round equipment is also the so-called Dual Beam. Here come two different frequencies simultaneously used so that the user can enjoy both the advantages of high details and a long reach.

Much modern Best Fish Finder also uses GPS to perform better location-based measurements still. In this way, for example, measure distances very accurately, but also the water level of a water body and some other details. Users are using GPS but also capable of their measurements to document and recorded on a map. This has the advantage that no measurement has to occur at the same place twice.

So we tested the Fish Finder

Thus, Easily the right fish finder for your very personal needs, see, we have taken the Fish Finder test in many different points of consideration. Because of course there is no Fish Finder which is equally recommended for all. Rather, it depends on what the device is to be used. Depending on the preference of an angler some categories are more important and some less important. All fish finders in the test in 2019 had to prove to us in the following categories:


In this category, we test how deep a fish finder can measure, and the depth to which the results of still are using. We pay particular attention to whether a particular model can also comply with the promises of the manufacturer. Because if a fish finder with a depth ranging from 900 meters is advertised, it should reach this depth without problems and thereby provide useful results. The fact that a device in this category, it is for a purchase hardly interesting because it is one of the key points in each Best Fish Finder.


The angle is in a fish finder an important corner because it also determines the range of measurement. A single measurement of only one frequency, for example, provides a fairly accurate picture but recognized on only a relatively small point of water. With Dual Beam already higher angle can be achieved, and it can be a range of about 60 ° capture, which is approximately three times that of a conventional single-beam. The best results but provides the so-called Side Imaging, which ranges up to 86° can cover. About the technical details you need to make in this category, but not too much thought. We analyze the fish finder test exactly which area a particular model captures and how well the results of the measurements fail here.

Processing and stability

Since Best Fish Finder always free to be used, they are high loads exposed. Therefore, we consider in this category if the material easily fresh- and saltwater resists and whether it even the occasional fall or extreme weather conditions survived. At best, a user should have to worry about the state of its sonar, and this can still use in any situation.

Measurement accuracy

Even the Best Fish Finder does not help much if the instruments do not provide accurate results. Therefore, we are testing at this point, how reliable the test results turn out of each device. High-class fish finder need for constantly good results differs between fresh and salt water can. In the latter, there is a significantly greater resistance by around floating plankton and other factors, so that the sound waves are longer move. For that reason, a sonar can be arising with false results and so that the users could be misleading by it.


During the presentation, we examine the way in which the measurements are processed fish finder. This is especially interesting for beginners who do not yet have the self-sufficient experience to interpret the results themselves. A good fish finder delivers so many self-explanatory pictures as possible and displays clean and clear. Especially in this respect is less sometimes more. If a fish finder can hide irrelevant information independently, which is a plus point in any case? It is also important in this regard, the display used. Only high-resolution, high-contrast LCD with adequate lighting can be read easily even in bright sunshine.


Regarding reliability we expect from the Best Fish Finder especially that it works well for extended periods and to provide acceptable results. A wear of individual components should not take place too quickly, as this is almost a sure sign of inferior materials. We simulate these tests from many anglers who are using Best Fish Finder over several years.

Price and performance

Each fish finder test the price always plays an important role. Cheap devices do not have all kinds of features, but may still be eligible for some users when high quality and are good results deliver. Expensive equipment may other hand allow much less error and should have many useful features. We consider this point very accurately whether a particular device is worth its price or if the manufacturer has too much to ask.

What should I look for when buying the Best Fish Finder?

Anyone planning to buy a fish finder, should especially their own claims to keep in mind. Buying a sounder for deep water is about little sense if you only on a local lake with shallow waters and want to fish. Moreover, just should not necessarily spend the same amount of money for beginners. Who has not yet determined whether the hobby fishing really suits him long term, can be a guild-first effective model set?

In general, quality plays an important role when buying. Whether cheap or expensive, each fish finder should have high-quality materials. This will ensure that the results are useful, and the device withstands some loads. Of course, you should pay attention to the delivery. At best, there is everything available, which is necessary for the operation and installation of the fish finder.

Especially at stationary models, it is helpful if already all materials for mounting are included. This feature eliminates the annoying additional purchases of tools.

Brief information on leading manufacturers

There are many different manufacturers of Best Fish Finders and also no-name products are not always automatically bad. To get a first impression, but we were the four largest and best-known manufacturers considered in more detail for you.

Internet vs. Traders: where to find the Best Fish Finder?

Anyone who has once decided to buy a fish finder faces the question of where this should be bought at the best. The Internet is an excellent point. It can be found here many different stores that have a wide assortment. Almost all current models can be in this way order quickly and easily, and you do not need to leave the house for buying a fish finder.

A big advantage is the comparatively low prices. Thanks to the strong competition, providers undercut each other regularly, and customers benefit from unbeatable deals. And there have a return policy for you if you got the defective items. Even when buying on the internet you have the full statutory warranty.

Also, you even have the right to return a fish finder within 14 days and get reimbursed the full sale price. Only the postage must then take in some stores buyers.

Buying a fish finder in retail is difficult for several reasons. Firstly, it is difficult to find even a store that carries the devices. Most electrical distributors refrain, so more of a shop specifically for fishing equipment should be consulted.

But even if such a person is first found, it offers only a fraction of the selection of the Internet. Not infrequently, there are only one or two devices that have already been replaced by the successor, and the prices cannot compete with the Internet generally. Because of the numerous advantages, it is therefore strongly recommended to buy a fish finder on the Internet.

The history of the fish finder

The history of the sounder begins with sonar. During the First World War, it investigated several states simultaneously independently. In Germany, first successful sonar inventor was Alexander Behm. In the years 1916 and 1920, he applied for two patents and eventually founded his own company for the economic exploitation of their findings.

In the following years, the technology was almost exclusively in the military for use. The research dealt with it, the principle to refine ever to enemy detect submarines sure to. After the end of World War II, however, the military significance sonar faded into the background.

Instead made now more and more economic companies to use the devices to which to make shipping safer. Also, fisheries discovered the benefits of sonar in this time for yourself.

Fish finder for home saw only the end of the fifties the light of day. At this time, recognized Carl Lowrance, founder of Lowrance and his sons get benefits of sonar in fisheries. In their excursions, they found that most areas of any body of water were completely free of fish.

These collect much more at certain points. Could determine exactly where these hot spots are an angler, he would logically be a much higher chance of success. The problem for the Lowrance family was not the technology partner because this was quite already available.

However, the devices cost about 2,000 dollars. Adjusted for inflation, this represents today almost 17,000 dollars. For most anglers that was much too expensive. Lowrance and his sons made it, however, a fully functional device for only $ 150 offer. That was the birth of the first commercial fish finder.

Today barely avoided an angler on the practical devices and thanks to the great success found ever new technological developments make their way into modern Fish Finder. Also, the prices were always lower because many companies are in constant competition.

Facts and figures about the Best Fish Finder

The fish finder has developed today practically a standard accessory for every angler. This is thanks to mainly the reduction of the equipment. Goods Sounders in the fifties still the size of a closet and several kilograms, thus there are that art today in handy devices weighing partly under 100 grams.

Thanks to smartphones, the devices can now also place arbitrary, because the data simply transmitted wirelessly can be and the angler so always has an overview, without having to hold the Fish Finder to be in hand.

Unfortunately, there are no reliable figures on sales or the distribution of Fish Finders. The mere historical development gives a good impression of it. Founded as a family company Lowrance employs nowadays, for example, more than 1,000 employees around the globe.

The technical development of fish finders goes hand in hand with the public availability of GPS.Since the USA their navigation satellites make available to the public, to make this the producers of echo sounders to Use. The technique helps partly for accurately locating and may anglers betrayed beyond where they have already searched for and which sites they previously rather neglected.

It is no surprise. Therefore, hardly that navigation companies such as Garmin have discovered the market for itself the Fish Finder. Conversely, also developed Lowrance, who’ve actually known for their fish finder, from the 1990s, many GPS devices.

Modern Fish Finder for private use Send mostly with frequencies from 50 to 200 kHz, but there are some exceptions. Interesting are the devices so that for water depths of up to 1,000 meters, which should be more than sufficient for any small and larger lakes. Only on the open sea fall Best Fish Finder partly to their limits. But here anyway fishing only real experts as de needs well off the positioning are significantly higher than in other waters. Overall, make Fish Finder but newcomers as well as professionals the fishing much easier.

Explains the depth sounder

The functioning and the structure of a sonar are comparatively simple. Each unit includes first a so-called encoder. It is a structure of a conductive crystal and a mating housing. This device is capable of ultrasonic waves to produce and emit. The sound waves propagate in the water and bounce back from everything that gets in the way. The transmitter serves simultaneously as a kind of microphone.

Based on the duration until the sound waves return can be seen how far an obstacle is removed. The intensity reveals in turn, said it could be the obstacle. If virtually all sound waves reflected, as is usually the basic body of water reaches. But If only part of the sound waves back, so it could also be rock formations, shipwrecks, plants or even fish act.

How accurate the results are available, mainly depends on the frequency of the ultrasonic waves from. The higher the frequency, the more detail can be sensed as the encoder can operate with more sound waves. The disadvantage of a high frequency, however, is the relatively small range. Because the lower the frequency, the farther to the sound waves propagate. To the water depth at certain, therefore, are low-frequency vibrations recommended. Many fish finders also set equal to a two different frequencies to the advantages of both types to combine with each other.

When using sonar, in any case, the user’s expertise is in demand. Because the results of, measurement must always be interpreted correctly. While there are devices that already automatically do this part, but the predictions are never 100% accurate. The only experience reveals a fisherman, which he has conducted a measurement and what he must observe everything. It is important, for example, to determine the speed of sound in water.

This depends on several factors, such as the salinity of the water, the temperature, and the pressure. Only with a good starting value can be ultimate with the depth sounder and precise distance information calculated. Although fish finder thus gives an angler many advantages, they still cannot take over all the work.

When looking at the technology can also be seen that the name fish finder is not entirely correct. Because no device is actually certainly, findable fish. The echo sounders give only indications of possible shoals.

6. Proper care

A fish finder can only function reliably when it is well maintained. This includes, in particular, to lay the cables properly and adequately protected against external influences. Also, however, it is also important to check a device regularly for its functionality. Thus, there are no faulty measurements later on. Check the leaves easily in shallow water, in which obstacles to the naked eye already visible. Displays the fish finder will not turn you on so possibly is a repair or a new device needed. Such functional test is about all 6 to 12 months is recommended. Of which from the device should be handled with care and, of course, always good.

The recovered information characterized hardly help in the search for fish or other things continue on the bottom of the water.

9. Proper placement

For a fish finder to work properly, it must also be correctly placed naturally. Where exactly is the best position, of course, depends always on the boat.
