How to Choose a Good Fish Finder? (Best Guide 2022)

A fish finder is one of the tools that you should look for if you have an interest in fishing and are curious about how to successfully catch your fish. Now is the time for you to look for an assistant that can respond to your needs, and a fish finder is one of the instruments that you should look for. Take a few moments to familiarise yourself with the fundamentals of fish finders before you begin the process of selecting the right one for your next fishing trip.

What is a fish finder?

Possessing a fish detector, which is a cutting-edge and practical piece of equipment, is one of the most significant keys to success for those who are interested in capturing fish and expanding their fishing territory. A fish finder, which is also known as a sounder, is a sort of useful equipment that generates a unique sound wave and then transmits it to the water in order to identify the pulses of sound energy that are reflected back from the surface of the water. If the sound wave comes into contact with any things as it is travelling through the water, it will reflect back to the fish finder. This is how fishermen are able to locate fish in a timely and efficient manner.

Why would be needed for a fish finder?

For anglers, having a fish finder is an absolute must due to the significant part it plays in facilitating the attainment of many fishing-related accomplishments and providing assistance for successful fishing expeditions. With the help of a fish finder, our working performance may be greatly improved, and we can travel to our destination more quickly and with a significantly reduced amount of trouble. This device piques my attention on a personal level since I believe it to be a very helpful instrument and an effective helper in that it offers a lot of amazing capabilities that can be used by any user, including myself.

The very first beneficial effect that a fish finder has on its users is that it enables them to acquire fundamental information about the depth of the water bottom and the characteristics of the area in which they are fishing, such as whether the area is shallow or deep, even or rough, whether there are any obstacles present or not, and so on. If we have a good comprehension of these aspects, we will be able to readily recognise the species of fish that frequent our fishing region as well as the structures on the bottom.

In addition, since the transducer is responsible for both transmitting and receiving sound waves, the fish finder is able to provide us with an estimate of both the quantity of and the size of the target. If we find out that there is a significant quantity of fish, we will simply opt to stop moving and remain in the same location. On the other hand, if we find out that the location does not satisfy our requirements, we will have to continue our search in another region. In order to avoid squandering a significant amount of time throughout a search, the use of a fish finder is an extremely prudent decision.

In addition, the fish finder may make it much simpler for us to manoeuvre our kayak or boat through the water by allowing us to determine the depth and structure of the bottom of the body of water that we are going to be travelling through. We may be able to deal with the unforeseen collision with the large reef or any other unknown item even if we do not know the bottom of the ocean. Additionally, we will be able to save a significant amount of time and energy by not having to speculate or take risks when steering our boat in the event that we are unsure of the outcome.

There are occasions when we are unable to locate our baits on the surface of the water because they may be suspended farther down in the water column. We are able to pinpoint their exact location because to the sound wave produced by the fish foundering.

In summary, the greatest fish finder may provide a lot of fantastic advantages for users, and it also demonstrates its value by increasing the capturing effectiveness in a way that no other instrument can. Having one is quite important for you, taking into account the aforementioned factors.

  • Garmin Echo 551dv Worldwide with Transducer

The first fish finder that I want to speak about is one that is produced by the Garmin brand, and it is an amazing piece of equipment that every fisherman should give serious consideration to acquiring. Your time spent fishing might be made more delightful with the aid of the Garmin Echo 551dv Worldwide with Transducer, which is equipped with all of the most recent and cutting-edge capabilities that are now accessible.

The cutting-edge Downvu and HD-ID transducer has a power output of more than 500 watts. This allows the sound wave to penetrate to depths of more than 2300 feet in order to identify fish, which, in turn, increases the accuracy of your results.

Because it delivers the best degree of efficiency, boasts a strong sonar, and contains a number of additional capabilities, this fish finder is one of my favourites. I use it often.

The most common complaint that people have about this product is that they wish it came with a chart plotter and a GPS; nevertheless, this is a very minor problem that does not materially effect the product in any way.

  • Lowrance 000-11146-001 Elite-5 HDI Combo

The Elite line, which is made of creative and cutting-edge products, includes the fish finder that comes in second place as the best overall option. It is a wonderful alternative for ensuring that your fishing trips are both profitable and fun, which is exactly what you want out of a fishing trip. This gadget claims an unique display with a size of 5.0 inches and a resolution of 480 x 480 pixels, and it makes the claim that it can show even the most minute image details with the finest possible quality, clarity, and brightness.

This high-quality fish finder comes with a number of other great features, one of which is a base map. The other is a transducer that can be attached to a transom, and all of these characteristics enable the fish finder to operate to its maximum capacity.

This item never fails to mesmerise and astound me with its capacity to perform incredibly well in direct sunlight as well as when seen from a number of different viewpoints. It is a phenomenon that never ceases to amaze and enchant me. The display is the one feature of it that does not live up to my expectations; if it is at all possible, I would want a screen that is considerably bigger than simply 5 inches in size.

  • Garmin Echo 200 Fish Finder

It would be unwise of you to skip out on the chance to get one of the amazing products that the Garmin brand is known for producing. This fish finder has a transducer with a dual-beam as well as an Echo 200, both of which allow you to observe a broad and large water region with a reasonable amount of ease.

This particular fish finder has a transmission power of 300 RMS, which is the reason why the image can be seen from a depth of 1500 feet below the surface. This fish detector may be used in locations with either deep water or shallow water conditions. Additionally, the 320 x 480 pixel quality of the two-dimensional screen makes it simple and straightforward for you to hone in on the fish that you want to capture.

Additionally, it displays a wide-angle that is up to 120 degrees, which enables you to watch everything that is going underwater in a way that is both crisper and more exact.

In addition to that, thanks to its cutting-edge Smooth Scaling technology, you are also able to learn the history of the sound waves, as well as the region through which you have travelled and where you are currently situated; this is also the most amazing feature that makes me appreciate using this product.

This fish detector, on the other hand, does not perform as well as the others do when it is dark, and its screen is somewhat smaller than those of the other versions.

  • Humminbird 409620-1 HELIX 5 DI Fish Finder

You may want to think about purchasing this fish finder since it has an incredible pricing. Because it includes Down Imaging and Dual Beam sonar, it will provide you with as much information as it can.

The colour display has a resolution of 480 by 800 pixels, which not only guarantees that it will provide you with visuals that are the clearest, brightest, and most detailed possible, but it is also the primary reason why I have such a strong preference for this particular product. The frequency is sufficiently high enough so that the transducer can send out and receive the sonar signal as quickly as is physically feasible.

Nevertheless, there is one issue, namely the chart plotter and the mount, that could be enhanced in order to make this product flawless.

  • Garmin echo 300c Dual-Beam Fish Finder

This fish detector is considered to be one of the most efficient and cost-effective options now available on the market, and a significant number of consumers have expressed confidence in its capabilities. This fish finder, like the 200c type, is fitted with Smooth Scaling technology, which enables users to see prior history while the current time is being shown on the screen.

Even when it is dark outside or there isn’t much sunshine, the picture that is being shown on the colour display is still able to be seen clearly and vividly. In addition to this, it performs really well, is incredibly quick, and has a very user-friendly interface.

It has both a modest price and a decent quality, making it suitable for anglers with a restricted budget such as myself. When I use this Garmin fish finder, however, the thing that worries me the most is that if the battery dies, I won’t be able to recharge it since it doesn’t come with a solar charger.

Ignoring the slight issue that is associated with the battery, this product is definitely a worthwhile purchase for the price that it is offered at.

Types of fish finder

You won’t have any trouble finding a wide selection of fish sounders on the market today. These devices are manufactured by a number of distinct manufacturers and are available in a number of distinct variants. There are three primary accessible alternatives for you to consider, and these are standalone, combination, and network fish finders. Your choice should be based on your specific requirements.

  • Standalone sounder

This type of fish finder does not include any additional or further functions other than helping you see what is located below and is suitable for those who have a tight budget as well as just fishing in a small or narrow areas. You can realise its function simply by looking at its name; this type of fish finder does not include any additional or further functions other than helping you see what is located below.

You just need to invest a modest amount of money in order to get this fish finder, and it still provides you with reasonably high performance along with a display that is sufficiently large. Taking into account the two options on the left is important if you want to increase the likelihood of achieving your desired outcomes.

  • Combo sounder

This kind of fish finder is a mix of the primary sounder and a number of extra components, such as a chart plotter, GPS sensor, black box, several screens, and so on. Those individuals who fish from boats of a size that falls somewhere in the middle of the size spectrum are the ones most likely to benefit from the use of a product that falls into this category.

  • Network Sounder

Users of this fish finder tool have the opportunity to access massive amounts of data from the primary network providers, which is why this product is considered to be at the most advanced level possible. Data sources like as radar, raster and vector GPS maps, video, and SiriusXM satellite radio are among those that are made available to us.

Even some of the vendors allow both Bluetooth and WiFi, both of which are managed by a sophisticated operating system that is prepared for mobile phones. The network fish finder is the product that owners of large boats often search for, and the efficacy of it is simply fantastic thanks to the numerous display system, the large-sized screen, and the clear and brilliant pictures it displays.

In addition, if you base your evaluation of each sounder on its frequency, you will see that there are three primary kinds that correlate to three distinct levels of frequency. These types are single, dual, and multiple sounders, respectively. Each variety is also suitable for the many applications you have in mind, and if you are unsure as to which model is the most suitable for your needs, the following recommendations for five different items can be of some use to you.

What Should Be Considered for Choosing The Best Fish Finder?

Because there are an infinite number of products available from a wide variety of manufacturers, styles, price points, and models, it is easy to become disoriented and confused when beginning the process of looking for and selecting the most appropriate fish finder that can respond to your inquiry the most or that can bring you the best results. If you do not have experience selecting this instrument in the past and are lacking in understanding about fish finders, it is unavoidable that you will get the incorrect one, which will not function in the most optimal manner for you.

You could have the opportunity to exchange the thing you just bought for another one if you’re fortunate enough to return the item you just bought. However, there is also the reality that a large number of consumers are unable to swap their purchase for another product nor are they eligible for a refund since they don’t realise they made the wrong choice until after they have already used the goods many times. As a result, giving great attention to your choice before making a move that might potentially empty your wallet is an extremely important thing to do. And for your convenience, I have compiled the following advice, which I have either received from my friends or found on my own:

  • Fish finder frequency

One of the most important aspects that purchasers are obligated to think over and deliberate over multiple times before making a decision regarding is the frequency. There are three distinct categories for fishfinder frequency: single transducer, dual transducer, and multiple transducer.

If you want to carry out detecting a shallow water region, the high frequency, such as 192 or 200 kHz, may work best for you. Each sort of frequency is helpful for the various purpose. If you want to conduct out detecting a shallow water area. If, on the other hand, you need to inspect an area of water that is rather deep, the fish finders that have a frequency of 50 kHz seem to be more appropriate for your requirements than the others do.

Because the transducers are able to create and receive a great deal of sound waves, the higher the frequency it has, the more information and the better the pictures you can acquire. This is in accordance with the recommendations of knowledgeable individuals.

  • Supply Power

Along with frequency, power is an essential factor that you have to take into consideration before making the appropriate choice when it comes to picking out a fish detector. When attempting to figure out how powerful a fish detector is, most people turn to the watt as their preferred unit of measurement.

If you are going to be working in the deep region, you are going to want the help of a fish detector that is both powerful and efficient enough. When the power is strong, information or data may be shown more rapidly and in more depth, and vice versa. This occurs as a result of the fish finder doing an analysis and translation of the sonar waves that have been received, after which they are shown on the screen. This happens after the transducer has received the sound waves that have been transmitted. If there is not enough power, this process cannot take place quickly, and as a result, the visuals that are exhibited at the end are indistinct and hazy.

On the other hand, when the power is strong, the sound waves travel at a much quicker speed, and the material that is shown on the screen is both more distinct and brighter. Because of this, it is advised that you use modest power if you plan on catching fish in an area that is shallow, as this will be much more ideal for you.

  • Display resolution

The display of your fish finder will be able to offer a greater level of clarity and specificity the more pixels it has on its screen. Resolution is directly proportional to the number of pixels on the screen. When the number of these dots increases, the content of your discovery is presented in its whole and in a more noticeable manner. A pixel is analogous to a little dot on the screen, and it carries a portion of the picture with it.

Therefore, if you need to get a general image without a lot of details, the fish finder with a low resolution is the best option for you to go with. On the other hand, if it is necessary for you to know the detail, precise, and exact message from underwater, the fish finder with a high resolution is the ideal thing for you to take into consideration.

Screen resolutions of 480 by 480 pixels or above are often required for a fish finder to be considered to have a reasonable level of visual quality. In today’s world, manufacturers frequently combine a high resolution display with a large screen size to create products that better meet the needs of their target audiences. If you are in the market for this kind of technology, be sure to check this aspect thoroughly or to inquire about it to the vendor.

  • Types of screens

There are now two varieties of fish finder screens available on the market today, one that is colour and the other that is black and white. If you have a restricted budget and do not need the usage of any extra or unique functions, the second option is the ideal one for you to go with since it is the traditional model and it is priced affordably. The first one is the result of recent and innovative technological development; it is not only able to show vivid and colourful photos of fish or other objects found underwater, but it also functions well while fishing in low-light conditions.

  • Transducer

The transducer is the most important component of a fish finder since it is responsible for the majority of the work involved in transmitting and receiving sonar waves. This equipment is responsible for emitting sonar waves, which are subsequently sent into the water. If the sonar waves come into contact with any objects that are submerged, the waves will be reflected and transmitted back to the transducer.

This fish finder device may be adapted to a wide variety of boats and crafted from a wide variety of materials, including plastic, wood, bronze, stainless steel, and so on. Other materials may also be used. If you want your decision to be appropriate for your demands and goals, it is quite essential for you to take into consideration the many kinds of transducers and the materials they are made of.

  • Cost

The cost is a significant issue that causes a lot of us to be confused and anxious a lot of the time. It is a very challenging chore to choose a fish finder that is typically available at a fair price and is of a good quality since there are so many different types of products that are manufactured and sold each day. Fish finder manufacturers cater to a wide variety of customers by manufacturing a wide range of fish finder models that can be purchased at a wide range of pricing points, from affordable to high-end.

If a product has a cheap price, it will most likely not have any additional features, and it will function most effectively in shallow water. If you do not have a need for more sophisticated features and are willing to utilise items that have a black-and-white screen, a tiny screen, poor pixel resolution, and low power, then this price may be appropriate for your budget.

You are in luck because if you are willing to devote some of your time to monitoring and gaining knowledge about special offer programmes on the websites of various items, you may have the opportunity to get a fish detector that is both affordable and of a high quality.

The expensive goods might provide you with a great deal of useful features and capabilities to assist you in an effective manner while also lasting for a very long period. When you have one of these fish finders, you will discover that nothing could be simpler and easier, including fishing and having fun. However, not all of us are in a position to acquire one, and even the most costly fish finder may not function to its full potential if it was not manufactured by a reputable brand or firm. It is quite clear that a big number of individuals are required to pay a substantial amount of money but do not obtain the goods that corresponds to their payment.

To put it another way, the price of a fish detector may have a significant impact on its overall quality, but if you want to be an informed buyer, you need also pay attention to where it was made.


In overall, it is possible to say that the greatest fish finder is a wonderful equipment that is both capable of and economical enough to considerably improve your success rate while you are catching fish. Do not be reluctant to add this clever device to your boat if you would want to make the time you spend fishing both more productive and more fun. Take into careful consideration the aforementioned considerations, then empty your wallet and revel in your success.
