Depth Finders Buyer’s Guide
Garmin Echo 551DV Fish Finder
The dual beam transducer uses the 77/200 kHz frequency and 50/200 kHz dual frequency. Additionally it has DownVu capabilities that allow to nearly photographically view the structure and fish underneath the boat.
The 5-inch high resolution display offers zoom, horizontal and vertical viewing, and a split screen mode for viewing the broadband sonar and down image side by side.
Other features include waterproofing, audio alarm for when to be ready to cast and catch. For easy installation the device comes with quick-release tilt-swivel and transom mount, and low profile trolling motor transducer.
Garmin Echo 100
For those looking for a black and white best fish finder under 200, we would recommend considering the Garmin Echo 100 model.
It features innovative target tracking technology that gives data on fish, structure and bottom. It features single beam sonar with the frequency of 200 kHz, which allows monitoring the underwater to the maximum depth of 600 ft. So it’s a more suitable device for fishing in freshwater lakes. The sonar power of the model is 100 watts (RMS).
This unit is also small, so it’s also the perfect choice for a small craft. The installation of the Echo 100 is a snap with the included quick release tilt mount.
Humminbird 140C Fishin’ Buddy
Humminbird 140C Fishin’ Buddy is one of the top rated fish finders among the portable type. So you can use it on your boat, on the leased boat, on the dock or for fishing from anywhere else. To use the device you won’t need to do any rigging or wiring. Instead it uses extendable transducer tube housing with the length suitable for most small and mid-sized boats.
The 25color TFT screen gives a clear image that can give you readings of depths of up to 240 ft. The charge of the unit can last up to 30 hours. It features SideFinding sonar that gives accurate readings. Its benefit is that you can point it in any direction and get full coverage of the area to find more fish. The temperature feature is included.
The wattage for the device is 1000 watts. Purchasing it, you have several options. You can either choose a black and white or color screen option. One more selection is of either dual or single beam sonar.
For ice fishing enthusiasts one of the recommended and top rated fish finders is the Humminbird ICE-3model. One of the most liked features on this device is the zoom flexibility. It allows you to zoom in not just to the bottom, but also zooming in for more details in any part you choose of the water column. The three color fiber optic display gives you a clear view of the readings. The extreme temperature LCD technology reports the lake bottom and automatically sets the flasher. Other features include dual frequency, maximum 200 depth capability and 800 watts peak-to-peak.
Transducer is the main part of the fish locator. It sends the sound waves and shows what is underneath the surface of the water. The sonar signal that the transducer sends into the water, bounces off of the objects that are underwater and then gets picked up by the transducer. The signal is then translated into a picture.
When checking the transducer, the most important feature is the cone angle. For a bigger perspective of the verges underneath, choose a bigger degree on the cone. The wider beam gives more coverage of the under water and allows locating more fish within it. However, its drawback is the quick loss of strength. Due to this, it cannot penetrate the water as deep as the narrow cone. The narrow one can go really deep even in shallow waters and can also give information on the composition of the bottom.
To get the most of the both there’s the dual beam type of transducers. It’s also called dual frequency and which combines both features in one unit. Other types of transducers are more specialized. They include multiple beams (can be or more). These cover a larger area of the underwater and can even give a 3D image on the display. One more option is the side beam transducer. These units shoot their signals to the sides, which increases the search area for fish.
When choosing the fish finder, you also need to choose the unit with the right frequency, which is also an important feature of the transducer. The frequency is directly related to angle of the cone. On most of the transducers you can find the following frequencies: 50, 83, 19and 200 kHz. A higher frequency will give you more detail on the screen. You can find models that offer dual, single and multiple frequencies.
Fish Finder and GPS in One Unit
If you are looking for an ultimate fishing tool, consider adding GPS to it. The Global Positioning System (GPS) with the help of satellites calculates your exact position.
A GPS is a must have for many fishers and having it in one unit with a fish detector is economical, space saving and convenient. Having the addition of a GPS gives you many benefits. It will give you the ability to mark hot fishing spots and easily return to them in the future, as you can mark the spot on the GPS and then track your way back to it later. These spots are called waypoints and on most units you will be able to mark hundreds or even thousands of them.
A GPS also gives you navigation through the waters. For this you will need to select a unit that comes with background maps and charts. One more benefit of the addition of the GPS is safety. Wherever you fish, you will have the confidence that at the end of the day the GPS will easily point you home. For example, you could be fishing throughout different locations during the day, or you could lose sight of land, or some severe weather could suddenly roll out. In such situations, a GPS will give you the exact direction to your home and will tell you how far it is.
How Does a Fish Finder Work
Understanding how a fish finder works will help you to understand how to use it. Fish finders work using sonar. It’s a technology that uses sound waves to display underwater objects. The fish finder produces the sound wave and with the transducer sends it through the water. Penetrating the water deeper, the sound wave starts to spread in the form of a cone (commonly called a beam). As the wave encounters objects within this beam, it sends the signal back to the transducer.
By calculating the amount of time between when the sound wave was sent and when it bounced back, it measures the distance and shows it on the screen. If the wave doesn’t encounter anything on its way, it reaches the bottom. If the bottom is soft and it’s just mud and weeds, the signal gets absorbed. A rock bottom will reflect a stronger signal back.
SideVu needs improvement
Powerful Fish Finder With GPS: Humminbird Helix Di is one of the latest best fish finders in the market. It offers a whopping big display of 800×480 resolution. It’s super bright display can be seen at heavy sunlight very easily. This is one of the best fish finders by Humminbird which provides highly accurate data on a big screen.

Its sonar detector will use the sound waves to show you to bottom contours along with identifying small and big fishes. The hard buttons of it help you operate it very smoothly and quickly. check-square-o
Cone angle is significant features to choose the good fish finder for yourself. Assume the cone angle as a point from the beginning of the transducer. It starts spreading from the point and the deeper it goes, it becomes wider. Please note that the more it widens and goes underwater, the more it loses its sensitivity. Usually, the cones range from degrees to 60 degrees. Normally the transducers come with a cone angle of 1to 20 degrees. Most of the time, 20-degree cone angle is good for most anglers.
Most of the transducers have a single beam. More advanced transducers come with dual beam, triple beam, side beam and more. These superior beams offer you the service to cover more water beneath your boat. This option comes very handily when you are looking for fishes in a big lake or river. If you are looking for the best fish finder, try to get a fish finder with at-least dual beam.
The display is another important factor while choosing the best fish finder. If your fish finder has a big screen, it can offer more data easily. Advanced fish finders come with color display along with other features. Advanced fish finders with big color display come with high resolution and great image like pictures of the objects below your boat.
Most of the advanced fish finders come with a GPS option. It is basically included in the device which will help you to find the spot you previously found. This will even help you to navigate through the lakes, rivers or in the ocean. This actually helps to minimize your effort to find the best fishing spot you found previously.

Fishing Gear Labs
There is nothing as annoying as staying on empty all day because you cannot locate any fish in the water. However, having a good fish finder in your boat or float tube can revolutionize your fishing experience. Things have changed today and the time of miraculous catch are gone and dusted! Thanks to modern technology which makes fishing efficient, less tedious and more fruitful. In this post, we have done an in-depth research and reviews of the best fish finders for the money. You don’t have to look any further!
A Global Positioning System (GPS) is an important feature of a fish finder. A GPS will help you locate a fishing ground you previously marked without much effort. Not only this but it will also help you navigate through the waters easily. With a GPS fish finder combo, you can fish even in new environments and still chart your way home. However, not all fish finders will come with a GPS option, so you need to make a right choice when buying fish finders.
This is what sends out signals to help you locate the fish. When it comes to transducers, the cone angle defines how efficient your fish detector will be. A transducer with a large cone angle provides a larger view of the underwaters, and this is very useful where there are no otherwise. Cone angle also determines the frequencies of a fish finder, the higher the frequencies, the greater the view in shallow waters. However, most of all, the best device is one that can deliver more than one frequencies.
In most cases, this functionality will come built in the GPS system. It will help improve your fishing efficiency as you will know whether you’re moving at the right speed for a particular type of fish.
Power is an important consideration when choosing a fish finder. In depth finders, power is measured in watts. A good fish finder should be powerful enough. High wattage means the device will show faster and accurate readings. The best fish finders have a minimum wattage of about 600 watts. However power will also depend on the depth of fishing, shallow water requires less power compared to deep waters.
Humminbird 409460-688ci HD DI
If actual screen size is not as important as advanced features, then the Humminbird 409460-688ci HD DI is a great choice.

It is an upgrade from the lesser Humminbird models and maximizes the fishing experience with GPS chartplotting, DualBeam PLUS sonar, memory storage capability, and a 25color digital display. When combined this all the best standard Down Imaging it is a superior device on in the fish finding market.
Garmin echo 500c
I have nothing but praises for this unique fish finding tool. Somehow Garmin has outdone the competition with a fish finder that has all the right features. The Garmin echo 500c Fishfinder is a slightly better item, than the one reviewed above. For users that have the extra money to spring for this upgrade, this is the better purchase. The 500c Fishfinder is the intuitive level fish finder, as it uses an uninterrupted sonar view. The product boasts about its priority software or Garmin Smooth Scaling technology. With this device handles depth changes without losing sight of any sonar histories. An additional feature allows users to rewind through their sonar histories. That is a sure way to not miss a stroke during any fishing adventure.
Humminbird 409470-600 698ci HD SI
As Humminbird products increase in price, so does the quality of their devices. The Humminbird 698ci HD presents an effective Side Imaging innovation at a value without extreme prices. It has a splendid 25color on a 5″ illuminated screen. The 698ci sparkles like a fish discoverer and chartplotter should. It uses very conventional 2D sonar includes Side Imaging and Down Imaging. This gives users the opportunity to see pictures at 100 feet deep. Wow that is really cool.
Humminbird 409140-859ci HD DI
Another Humminbird combo? Well it isn’t just bias. When the objective is to catch all the fish possible, the correct hardware is significant. Poles, reels, and watercraft can take an angler far. To ensure they know where the fish are gnawing, more fishermen are swinging to the Humminbird 409140-859ci HD DI Combo Color Fish Finder.
Humminbird 409150-899ci SI HD
I rank the Humminbird 409150-899ci SI HD Combo Color Fish Finder as superior. Except for the online media hype being unclear about what you are getting or how to redesign. This isn’t to say that this is a bad Humminbird model, but lets assess it fairly.
How does a fishfinder GPS work
In orbit around the earth in geosynchronous positions, numerous satellites are sending out radio signals that your GPS is picking up. By doing mathematical calculations, it figures the angle between the location of the receiver and multiple satellites that give you a fix. This them is converted into latitude and longitude and inside your GPS on the charts that are calibrated in longitude and latitude and icon symbols is displayed indicating where your boat is now.
When your boat is moving the calculations that indicated the direction and the amount of time of travel between point-to-points gives you your speed. Waypoints on the chart and line between them and your simply compare your icon against where the line is. The closer you follow the line between two waypoints the more accurate your navigation.
How to mount a fishfinder GPS
After opening the box, verify that all mounting hardware is there. Mount the transducer where the directions say. Run the wires to the unit. You have to drill holes. After doing so make sure you waterproof and seal all of them. Take particular care where the transducer cable enters the hull of your boat. The fish finder’s mount mounts where it is easily accessible and visible. This will depend on the type of boat you are using. Most anglers place the transducer on the transom. They place the display unit near where they sit while maneuvering the boat.
What is the difference between a fishfinder and depth finder?
A depth sounder is a coarse device that you send out a pulse and measures the return to give a bottom sounding. A fishfinder has much more discrimination. It allows focus on smaller objects at varying depths. The controls, therefore, are more sophisticated. With units that have a multibeam capability. You can see a three-dimensional view of what is beneath your boat. This allows you to identify fish much better. It also gives precise depth positions.
The most expensive model, the CHIRP SI GPS G2, has a maximum depth of 1500 feet out of the box and 2500 feet with an add-on. It has a wide frequency range along with that, meaning this can be considered the best fish finders in the series for its depth range.
Most sonar systems send one frequency at a time. You can look for information from a high frequency or a low frequency, but you cannot look for information for both at once.
Over the course of an afternoon, this can mean missing out on dozens or even hundreds of fish.
But the Lowrance Hook 7 can be considered the best fish finders for people looking for stellar sonar and a series of cool features beyond sight and sound.
As a matter of fact, this feels so high-tech that it makes you think Lowrance should be making technology for James Bond. Anglers can really rejoice in the fact they work for us and not MI-6.
With other fish finders, you need to manually adjust your settings to see fish and other details clearly. With the Lowrance Hook-7, you can avoid that responsibility with advanced signal processing. This feature gets that done for you, making it easier for you to focus on catching fish.
TrackBack allows you to review your recorded history after your journey or on your next one. Everything from structure transitions to fish targets can be reviewed easily.
That makes the Hook-the best fish finders for anglers looking to keep track of their fishing trips after they return.

Doesn’t matter whether you are a professional angler or just a passionate beginner, when it´s about getting the biggest fish we all agree that we want the latest, newest and most useful gear with us. 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 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.
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.
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).
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.
Higher frequencies should be used for mid-water depths.
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”.
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.
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.

Considerations when researching new echo sounders
I have listed some points you may wish to consider when purchasing a new or upgraded sounder.
Firstly, what is the sounder’s intended use? If it is primarily for navigation purposes and an accurate measure of water depth, then a depth sounder with a digital read-out and without all the fish-finding functions will do the job.
If its intended use is for fishing, a sounder specifically designed for that purpose would be needed.
Generally, when first starting out, fishers start with a basic entry-level sounder, and in most cases that is all they will ever need. Those who venture out to deeper water will require a higher performance transducer, low frequency output, and functions such as TVG (Time Variable Gain).
Because today’s echo sounders and transducers are manufactured to the highest technological standards, it is difficult to make comparisons between the different models within the same price range. This is because they generally use similar technology and have similar screen view presentations, operating functions, frequencies and settings. The only real difference is in the menu systems.
Transducer performance can range from low, medium to high, which affects the depth at which underwater objects can be detected. Therefore, the depth range the sounder will be to be operated must be within the transducer’s performance range.
Screen view options Full screen view showing the complete water column from the bottom to the surface. Split screen view with each side showing a different section of the water column, using a bottom follower. Full screen View Bottom Lock.
It is always handy to have a large display screen. For many small boat owners this is not an option due to the cost, and in many cases there is no room to fit one.
Often this is no major issue because echo sounders specifically designed for fishing usually feature a range of screen view options that allow the operator to enlarge, expand or zoom any section of the water column within the display screen.
When targeting demersal fish (those near the bottom), I set the display screen on full-screen view to start with. Then, when I detect fish targets or a bottom structure I want to have a closer look at, I switch over to picture zoom, bottom zoom, marker zoom, or bottom lock to closer investigate the section of the water column in question.
When I want to view fish targets, such as pelagics, in the middle levels of the water column, I switch from a full-screen view to upper and lower depth ranges, where I can view any section of the water column – for example from 30-60 meters.
Some examples of the situations described above are shown in screen captures hereabouts, which are acoustic images of fish and bottom structure, using different screen view presentations commonly found in echo sounders designed for fishing.
During rough weather conditions the recording of the seabed can become very ambiguous, caused by the boat heaving and pitching, rising and falling over the swell and waves. In this situation I always switch over to bottom-lock, where fish targets can be seen much clearer above the seabed bottom-lock line.
Some fishers prefer to use the seabed bottom-lock function even in calm conditions; I am also one of them. I commonly use the bottom lock display when fishing rivers, to obtain information about the nature of the bottom; this can be achieved by closely observing the changes in the bottom echo signal below the bottom lock line. An amazing range of information about the nature of the bottom can be obtained from this function. Viewing a section of the water column using depth range function. The column to right is the A Scope.
Transducer power output and frequency selection
The performance level of the connected transducer determines a sounder’s operating range.
Sounding in water depths of 0-60 meters only requires a low performance transducer. Operating depths of 0-200 meters will, at the very least, require a medium performance transducer.
Sounding in water-depths of 200 – 600 meters will only be achieved with a high performance transducer.
High frequency (200 kHz) is selected in shallow water, and will produce highly resolved screen pictures in shallow water depths. The depth-range at which this frequency can be operated is restricted, due to its high acoustic absorption loss through the water during transmission.
Lower frequencies (83/50/2kHz) should be selected in deep water, and will produce less resolved screen pictures. Due to their low acoustic absorption loss through the water during transmission the depth-range at which these frequencies can be operated is less restricted.
It is also important to understand your transducer’s beam angle as this allows you to estimate the size of the detection area under the boat in the depth-range you are fishing.
For example, if you are fishing in a depth of 200 meters and your beam angle is 4degrees, the transducer’s detection area, directly under the boat, will cover an area of approximately 15metres in diameter.
Mobile or Fixed
For more settled fishers and watercraft owners, a much better option is a fixed unit that they will be able to mount at any precise location on their ship. In accordance with your preference or needs, it is possible to mount the transducer either on the stern, hull or trolling engine.

Global Positioning System
GPS is the most imperative feature of best fish finder GPS combo. With an excellent GPS, you don’t need to worry about getting lost in your fishing adventure. It will instantly pinpoint your exact location. Also, you should consider saving your favorite fishing spots. Some units come with pre-installed maps that provides precise locations of lakes and rivers along with popular fishing spots. Whereas some fish finders let you connect with your marine radio and transmit particular coordinates in case you face any problem while you are on the water.
To make sure you are getting best out of your fish finder, you must ensure that you are getting a sufficient range of depth. If you prefer fishing in shallow waters, then a low-end model might be sufficient for your needs. However, if you are looking forward to deep sea fishing, you must consider a device that has longer range. For shallow water fishing, even 500 yards is enough whereas for a sports fisherman, a unit with 1500 feet or above depth range is preferable so he can easily see everything that is beneath him.

Fish Finder Transducer
When you’re looking around for fish finders online, the display image is often on the console/screen that you look at while in the boat. However, this piece doesn’t really do the “heavy lifting”, rather, another piece called the transducer is where the bulk of the work takes place.
The formal definition for “transduce” is the process of converting one type of energy to another. In the case of a fish finder, the transducer emits sound waves (or “pings”), then receives the returning signal and sends that to the console in the form of an image. Therefore, the transducer is often mounted on a different part of the boat than the console, usually connected by a cable.
Most fish finders will already come with a transducer, so you don’t have to worry about trying to match a fish finder with the correct transducer. However, we do recommend paying close attention to the transducer specs because different water conditions will require different transducer settings for optimal detection of fish and smaller objects. Similarly, perhaps you already have a fish finder and want to change to transducer because you now own a different boat or fish different waters than you used to. In any case, knowing the basics of transducers can really help you feel comfortable in the choice you make.
We won’t get overly technical here, but the frequency is one of the more important specs to pay attention to when picking out a fish finder and associated transducer. First of all, how do you know what number is the frequency if it is not labeled with “frequency”?
Frequency is measured in the units “Hz” (Hertz), where HZ means per second. Fish finders typically operate in kHz, so if you see this unit, then you’re looking at the frequency! Some of the most common frequencies you will see are 50kHz, 83kHz, and 200kHz.
If you have been looking for a fish finder already, you may have noticed that often times there is a “/” (slash) between two numbers, such as 50/200. This means that the transducer can operate both at low-frequency and high frequency. The fish finder will either be able to toggle back and forth between the frequencies, or sometimes they can display both in a split-screen appearance.
What Frequency Do You Need For Your Fish Finder Transducer?
Low-frequency (e.g. 50kHz) and high frequency (e.g. 200kHz) transducers each have their own strengths and limitations that are pretty much opposite of each other. Depending on where you’re fishing, a low frequency may be more suitable than a high frequency, or vice versa. Here’s the basic information you should know when selecting a transducer frequency:
Low frequency pulses can travel further through water. Therefore, if you are fishing in deep water and want to know the water depth, as well as see any bottom dwellers or snag-prone objects, then a lower frequency may be best in that situation. If the water isn’t too deep, then you may prefer a higher frequency, as the pulses simply won’t need to travel as far. Furthermore, high frequency pulses offer better detail on the screen, and therefore may be better at picking up smaller fish or details about the vegetation in the water. If you’re on a lake with varying depth, type of fish, or water clarity, then it may be beneficial to have a Fish finder with both low and high frequencies available.
It’s tough to know exactly what frequency will be needed for a particular depth because it also depends on water temperature and murkiness (lower frequencies are better for murkier water). The “general” threshold commonly used is 200 feet, whereby higher frequencies, especially a single frequency, may be best suited to water depths under 200 feet. Lower frequencies, such as 50kHz, are likely to be better for water depths greater than 200 feet. But like we said, this is a general guideline and not meant as a written-in-stone rule.
If you’re on the hunt for a new fish finder, the power, which is basically the strength of the signal being emitted, won’t be an overly important spec to consider assuming you are already considering the frequency. In a nutshell, lower frequencies are typically coupled with a higher power, and higher frequencies are usually coupled with a lower power. Given what we already know about transducer frequency, we can guess that lower power is ideal for reaching greater depths. This is in fact the case, and is why you will often see frequency reported in the product description, but power may be a little more difficult to find. If you are looking for the power of a particular transducer, it will have Watts (W) as the units, and they usually range in the area of 100-1000W (RMS).
One thing to note about transducer power is that while you may be able to mix and match components of different fish finders, mixing components from systems with way different power specs can decrease the longevity of your fish finder. So while it could work in a pinch, and sometimes even improve the quality of the images you receive if you swap to a transducer with a higher power, that may come at the cost of decreased durability.
Transducer Beam Width or Angle
If you’re learning about the different features of fish finders, often times you will see information about the beam width or beam angle of the transducer. This can be considered your area of coverage, or the area you are able to “see” underwater. When the sound pulses are emitted from the transducer, they are emitted in the shape of a cone, whereby the covered area grows larger the deeper the sound penetrates (like an upside-down ice cream cone). Therefore, smaller beam angles cover less area while larger beam angles span a larger area.
The beam width of your fish finder will depend largely on the frequency. The lower the frequency, the larger the beam angle. The higher the frequency, the smaller the beam angle. Low frequency/large beam angles are great for covering a large area underwater and gaining a general sense of where the fish are and how many there are. High frequency/narrow beam angles are great for shallow depths and provide more detail of the underwater environment.
Fish Finder Console
Alright, enough about how best fish finders work, just show me the fish! The console is the part of the fish finder that will map out the depth and display any fish in the area. There is actually quite a variety of consoles available, from black-and-white to color, from a small to the large screen, different resolutions, etc. So while it’s extremely important to focus on the transducer specs, knowing more about the console can increase the chance that you will end up with a fish finder that is perfect for your needs and wants.
Console Screen Size
This is a pretty simple one. Many people like consoles with a larger screen, but they tend to be more expensive as well. Chances are if you’re looking at a fish finder that is relatively expensive and has a large screen, that it may also be capable of displaying more than one image. For example, dual frequency fish finders can sometimes display a split-screen image, but you need a large enough screen for this. So if you’re wondering why it’s so much more expensive for a fish finder with a larger screen, check the more specific capabilities like dual frequency and split-screen display, as that may be a factor as well. However, please keep in mind that a large screen doesn’t have to mean advanced capabilities, there’s just a decent chance that it does.
One thing to keep in mind about screen size, especially if you are looking for a fish finder as a gift, is eyesight. While fish finders are often mounted in convenient locations on the boat, you won’t always necessarily be directly next to it. It can be a hassle to always have to get to the screen, move in close, and squint to see what’s on it, so if any eyesight issues are at play, it’s probably better to lean towards a console with a larger screen.
Console Screen Resolution
May you notice some brands boasting or higher-end fish finders boasting about their higher screen resolution? So why does the resolution on the screen of a fish finder matter? Simply put, the more pixels there are on the screen, the more detail can be displayed. But how do you know how many pixels are on the screen? If you look at a product description and see something like ‘480×640’, that means the screen is 480 pixels wide by 640 pixels tall. Sometimes you may also see or hear “high definition” or “HD”. While there are subtle differences between “resolution” and “definition”, they are practically the same when it comes to the actual application.
Without going too in-depth, there is a little bit of interplay with screen size. Larger screens are usually capable of packing in more pixels, so it’s a good idea to consider both. For example, let’s say we have the one really small screen and one really large screen, both with the same resolution. There will be no difference in the amount of information displayed. The big screen will simply display a larger image. However, let’s say we have two screens that are the same size, but one is high resolution and the other is low resolution. The high-resolution screen will provide more detail than the low-resolution screen.
On certain fish finders, usually the higher-end models, you may notice they talk about “down imaging”, “DI”, “down view”, or “DV”, or some variation of that general form. This is a pretty cool feature that can definitely come in handy at any time, but especially if you are in an area with lots of vegetation on the sea/lake floor, or if you’re trolling close to the shore.
The benefit of down imaging is that it can provide a much clearer view of what is directly under your boat. In this case, a high-frequency sound waves are sent out in really small “slices” instead of a wide cone. The result is a very clear image that almost looks like a photograph because it provides so much detail, it just cannot cover as large of an area as the standard transducer function. However, these down view images can usually share a screen with the standard display in order to provide a comprehensive sense of the underwater environment around you.
Black and White vs Color Console Screen
The obvious tendency here would be to go for a color screen, but color screens are often more expensive, so is it really worth it go with an expensive color screen over a cheaper black and white display? Here are a few things to consider when trying to make this decision:
Color screens tend to offer better contrast and are often better for identifying fish that are close to other objects, such as the bottom and associated vegetation. Color screens can also sometimes employ higher resolution, which could further assist in this matter.
So when is a black and white display favorable? For starters, if you are on a budget, then you can definitely find cheaper black and white displays. Similarly, if you are a beginner and not really sure what your preferences are or how much you will use it, then we would suggest a basic model learn on first, and this will likely be black and white.
At the end of the day, it’s not only about black and white versus color. All features need to be considered, and perhaps one particularly important feature to consider along with display color is screen resolution. In our opinion, resolution, or “pixel count”, is much more important than the color of the screen. So let’s say you are deciding between a black and white display and a color display. If you notice the black and white display has a higher screen resolution than the color display, then the black and white display could be a good option if you are looking to save some money with the best fish finder and don’t need anything overly advanced.

How Fish Finders Work
Maybe you do not know how the fish finder works. Knowing this helps you to operate it. The inventor of the fish uses sonar sound waves that reflect the sound of objects in the water to display objects and objects in the water. The image of the object can be formed because the sonar sound is re-reflected from the object back to the fish finder. It may seem simple, but actually, this technology is costly because the price of technology development is costly and takes a long time. Almost all fish finders use this sonar technology.
Large Touch Screen
Lowrance HDS-Genuses a large touchscreen with a size of inches so that your view will be more convenient and comfortable. With this touch screen you can also use two maps at once without reducing the display resolution on the monitor. If you are modeling the bottom of a lake or river in real-time, the resulting visualization is also excellent.
The mapping technology installed on this tool is very sophisticated. Its results are at high prices. Using this tool allows you to find fish. You can scan all areas around you and produce 3-D mapping with high-resolution monitor quality.
Integration with your mobile WiFi device
NSS Evois unique because you can integrate the operation with WiFi on your mobile device. So you will have two ways to control the operation of this unit, i.e., with NSS Evotool directly, the second by using your mobile device.
Easy to use
Lowrance HDS Genis made in such a way that it is easy to use despite its many features. The touchscreen is still augmented with a button on the right so that it can be operated when the user uses gloves, for example when winter or when the air is very cold which requires the user to wear gloves. This unit is also waterproof. The manuals available in the purchase package are quite complete, and although without reading the user manual can still operate as it is easy. HDS Genis also compatible with many of the available transducers on the market.
HDS Gencan use a wireless connection making it easy to connect to other devices such as the HDS GenTouch display. But to do this must be connected to DC power and electricity. Also, wireless connections can also be used to perform software updates.
The Sonar CHIPR is very good, precise and accurate, and there are also chartplotter with features that are complete and many and compatible with many other mapping packages such as Humminbird LakeMasetr and Navionics.
With Helix Si you can see objects in the water well up to a depth of 1500 feet with a regular Sonar. When using Side Scan Sonar can meat to a depth of 240 feet on each side of your ship. The use of Sonar Side Scan can be tailored to your own needs.
Garmin Striker uses CHIRP technology to create what visualization is in the water. This technology uses traditional sonar and single frequency. Also, the GPS technology of this device is quite good and can know the position in real time. The GPS hardware is located inside this waterproof device.
The screen of this device is small, but more features than similar devices with the same price range. You have nothing to lose when buying this Garmin Striker 4.
Garmin Striker is not good for sea water. This device is more suitable for use in rivers or lakes. It is quite disturbing but comparable to its ability. Can be used for seawater but the results are not good.
Shapes and Views
Each fish finder has different screen sizes. The high-resolution screen is better than the low resolution because with the high-resolution screen then you will be able to see more detail. Screen size we recommend at least inches with a minimum resolution of 240 pixels. Below that the result will not be good. Maybe you need to set aside more budget to be able to buy fish finder with big screen and resolution. With a bigger screen then the thing that is displayed will be more so that the information we also get more.
Then we also suggest you find fish finder with the color screen. Fish finder with a color screen will give a clearer picture of the fish finder visualization results than on the monochrome screen.
You need to take into account the electrical power required for the fish finder to work. With higher electric power allows better search results and commonly used in deep waters. High power is estimated at over 1000 watts. As for shallow waters lower power to power about 600 watts because the workload is not heavy.
