Reviews of 5 Best Fish Finder

1. Garmin 010-01809-00 Striker 7SV with transducer – Best Side SONAR fish finder


Although available in multiple screen sizes, the Garmin Striker 7SV fish finder really comes alive with the 7-inch screen. This high-resolution display occupies most of the face of the device. The color images look pretty vibrant in bright sunlight to calm evening glow. There are dedicated buttons on the right side of the screen which reduce button clicks for every action.


The Garmin Striker 7SV fish finder uses a highly efficient CHIRP transducer. This sends more energy into the water by pulsing a window of frequencies instead of a single frequency. We could see the clear results of the whopping 500W RMS energy it sends into the water column for better target separation and distance range. Under ideal water conditions, the native transducer can scan 800 feet with traditional SONAR.

Side Vü and Down Vü

The Garmin Striker 7SV fish finder offers both side imaging and down imaging. The CHIRP technology comes into play here as well since it uses a CHIRP transducer. The Side Vü and Down Vü also send a CHIRP-like beam instead of a single frequency. You can scan clouds of fish and see their exact shape through these two kinds of imaging and CHIRP.

GPS and Waypoints

The highlight of this feature is that you can mark waypoints on the map where the fish are biting and other important locations. The GPS helps you navigate back to these points with a pathway displayed on the screen. It also shows your position relative to the waypoints. The waypoint maps can be transferred to other Striker or echoMAP models.

The other features of this fish finder include a flasher. We found this extremely useful for fishing when stationary especially in shallow water. Anglers would use it for ice fishing or jigging for crappie. GPS also enables it to calculate your vessel’s speed even if you are almost standstill.


  • CHIRP, Down and side scan
  • Clarity and target separation
  • Built-in GPS
  • Waypoint mapping
  • Flasher
  • Maximum depth 2,300 ft freshwater, 1,100 ft saltwater


  • Cannot add full maps
  • No microSD card slot

2. Garmin Striker 4 Built-in GPS Fish Finder - Best portable fish finder and value for money


We expected the Garmin Striker 4 fish finder to be portable and somewhat rickety, given the price. It turned out to be compact but otherwise excelled in its physical design. It has a moderate 3.5” screen with buttons below for simple operation with gloved hands. It is IPX7-rated and can be submerged into 1m water for up to 30 minutes without damage.


We were pleasantly surprised to find CHIRP in a small and affordable package. The Garmin Striker 4 fish finder uses a dual frequency CHIRP. The native transducer can be upgraded for a lower frequency beam too since the fish finder itself is capable of scanning at 50 kHz. With CHIRP, we saw much sharper fish arcs and separation compared to traditional single and dual frequency SONAR. It makes it easier to distinguish a school of fish from a ball of clump.

This is supported by SONAR History Rewind which allows you to scroll back in SONAR images to mark waypoints from the past. 

You can mark up to 5000 points with several icons available for use.

We really liked the Fish Symbol ID feature which enables the unit to display special fish symbols on the targets it identifies as fish. These could also help you identify small fishes from medium and large fishes. This fish finder also has a flasher for ice-fishing and fishing in shallow waters.


  • High-sensitivity GPS
  • Fish symbol ID
  • Waypoint Maps
  • Flasher
  • Vessel speed
  • Maximum depth 1,600 ft freshwater, 750 ft saltwater

Complete Buying Guide On The Fish Finders​

The newer fishermen and some of the old ones too, are not completely clear on the fish finder technology. With the gap in information, you may end up paying for a device you don’t require or one that doesn’t match all your requirements. Either way, you don’t get the full value of your investment unless you know what to look for in the best fish finders for you. So here’s a complete buying guide on the fish finders.

What is a fish finder?

A fish finder is a device used to locate fish underwater using sound waves. This is called the SONAR technology, wherein sound waves are transmitted and reflected waves(echo) are received to calculate distance. The fish finder has a screen where these electric sound signals are shown as graphical representations of fishes and other objects via small symbols. It also calculates the depth of the water, provided it has the range.    

How does fish finder work?

What is fish finders

The fish finder device is either mounted or placed on the boat or the vessel. Most of them are portable handhelds. The fish finders have a transducer which produces the sonic wave and transmits it into the water. This wave disperses in the water in a conical manner. As it hits any object, part of it is reflected back and received by the fish finder. The time it takes to receive the echo is measured and the velocity of the wave is known. Determining the distance with velocity and time is easy. The wave could be reflected by any object underwater and the fish finders are equipped to differentiate between them and fish based on the size and shape of its swim bladder. In fact, this information can be used to tell between various fish species too.

The areas where the sound wave doesn’t hit any obstruction, it reaches the sea bed. If the bottom only has dirt, it may get soaked up and return a light echo. If it’s a rock bottom, you get a powerful echo.

This information is displayed on the screen in a more readable format. You can adjust some parameters of the screen while others are fixed like the maximum resolution, display size etc., so you must make a purchase accordingly.

The screen looks something like this:


How to choose the best fish finders?

There are some technical details that help sort through the fish finders and find the best ones for you. We check the following the specs: 

1. Transducer Frequency:

The transducer is the part of the fish finder that emits and receives the sound waves. The frequency of the sound wave is determined at the transducer. The usual frequencies range from 50 kHz to 800 kHz.  High frequency transducers have shorter wavelengths and hence can discern smaller objects/fishes. In short, they pick up more details of the underwater situation. Higher frequency transducers have lower range, so they are best used in shallow water. A 200 kHz transducer will have a clear range of around 600 feet. A 50 kHz transducer at the same power will range around 2000+ feet but it cannot pick up as much detail. It will only detect fish that has an air bladder larger than 1” (the wavelength of sonar).  

These days, most fishermen resort to dual frequency transducers. These emit both a lower frequency wave and a higher frequency wave with Wide Beam and Narrow Beam. This way you can get both depth and detail on the fish finder screen. Multiple-frequency transducers also exist.

Dual frequency transducers Wide Beam and Narrow Beam

2. Cone angle:

A cone angle is the angular width of the sonar wave. This tells you how wide the wave beam travels under the vessel. Lower frequency transducers usually have a wider cone angle, so they cover a larger area and find fishes that aren’t under your boat.  They may not be detailed enough to show fishes distinctly if there are more than one fishes crowded at the same point.  The higher frequency waves are more focused and used to find fishes right under the vessel. The average cone angle is between 15-20°.

3. Power:

The power and wattage of fish finder is an important measure of its fish finding range. Higher the power, the deeper the wave penetrates. It’s important to understand how power ratings are tied with the transducer frequency. At 50 kHz, for every 100W of power, you get to 400 feet more.  But at 200 KHz, with every 100W the range increases 100 feet. The wattage ranges from 600W to 3000W. For shallow waters, you would require a lower power.

In a dual frequency fish finder, the power will break between low and high frequencies based on your requirements. Always note the RMS power of the fish finder. This is the power that it can maintain. Manufacturers often mention the peak power, which is the instantaneous power of the unit, to confuse the buyer. It’s typically much higher than the actual RMS power.

4. Screen Size:

The choice of screen size is based on your preferences. If you prefer a smaller portable unit, the screen would be small. The details would have to be cramped in what space is available. Wider screens are easier to monitor. Wide screens are also useful if you want to split the screens to show more than one kind of data.

For example, if you want to see GPS data and fish finding data on split screens or data from transducers of different frequencies, a wider screen helps.

5. Display Size:

The resolution of the screen determines how grainy the picture looks. Higher resolution results in a clearer and more detailed picture. The minimum resolution recommended for a decent image is 240x160 pixels. Higher resolution fish finders around 640x640 bring truly amazing image quality.

Screen resolution fish finder

6. Color Screen or Gray Scale? 

Black and white screens are the more economic choice. But in fish finders, you have good units with colored screen within small budgets too. Colored screens are easier to read in the sunlight. You may have to peer into black and white screens in bright sunlight.

7. Down Scan and Side Scan:

Fish finder can scan in two ways: side imaging and down imaging. Either they scan directly under the vessel. Or they may scan under and to the sides of the boat. This is closely related to the cone angle concept or beamwidth. Side scans allows you to cover large areas of the sea but their power decreases in deep water. So you must know how deep your fishing destination will usually be, before selecting the scan technology. You also get fish finders with dual scan which can range to the sides and under the vessel effectively.


8. GPS Combos

GPS is a must-have feature in fish finders now. The GPS is used to determine your actual geographical location. A GPS module allows you to mark the points in water where you caught a good haul and save them for later. You can map your location in real time and so can the search and rescue team if you wind up in some trouble.  The accuracy of GPS tracking becomes a buying consideration now and not all fish finders are equal in this regard. You can add GPS sensors to some fish finders later.

CHIRP is the new technology in the fish finder block. Short for Compressed High-Intensity Radar Pulse, CHIRP fish finders transmit a range of frequencies than a single of dual frequency. For example, they transmit all frequency in the 40-75 kHz range. They put out more sonic energy into the water and achieve significantly better resolution and target detection that traditional fish finders. You can spot separate fishes within inches as opposed to several feet with normal technology. They also have a deeper range.


What is the difference between a Depth Sounder and a Fish Finder?

A fish finder usually has a relevant and useful mix of features. Whereas the depth sounders are either too simple or too sophisticated. A basic depth sounder will only give your depth of the water body and the temperature. A sophisticated one might only help professional anglers with multiple fishing settings. Fish finders have everything in between. They provide a graphical representation of underwater activity and fishes, not just a digital readout. You can also see the trend in depth over the last few minutes.

Fish finders are generally cheaper than a full-blown depth finder and show more information than a basic depth finder. There are fish finders with plentiful information and features under $100 too. They are simply the better deal.   

What is fish finder transducer?

The transducer is that part of the fish finder that sends and receives the SONAR waves. These signals are converted to the findings on the screen display of the fish finder. You can upgrade the transducer that came with your fish finder with one that has matching plugs, frequency and wattage to the fish finder.  Transducers differ in the way they are mounted on the boat. The mount determines which type of vessel can use the transducer. ​

These are:

1. Transom mount transducer:

Transom mount transducers are mounted on the transom of the boat as the name suggests. You need to drill holes near the bottom edge of the transom to attach this mount. This is the most common type of mount supplied with the fish finders. It is made of plastic and is more affordable compared to other mounts.

Transom mount transducer

Transom mount transducers remain completely submerged in water and extend a little below the hull. Such transducers are best used on Planing hulls of less than 8 meters. These are sensitive to disturbances around them so they shouldn’t be mounted on large boats because the propeller will obstruct their operation. They are not as responsive as the through-hull transducers so they are recommended for low-speed trailered boats. 

2. In-Hull mount transducers:

These are also called shoot-through transducer mounts. The biggest advantage of these mounts is that you don’t have to drill holes in your prized boat. They are glued on to the boat. The constraint is that it can only be used in vessels with fiberglass hulls. The in-hull mounts are epoxied inside the hull. So the SONAR is sent and received through the hull. Consequently, In-hull transducers are generally the least sensitive of the lot. Their range and ability to detect fish is reduced compared to mounts that put the transducers directly in water.

In-Hull mount transducers

Another disadvantage is that the fiberglass hulls may be reinforced in places with wood or may have air pockets. The in-hull mount can’t be attached in such places or these may interfere with the SONAR. 

3. Through-hull mount transducers:

The Through-hull mounts position the transducer right into the water.  The mount is loaded on the bottom of the bottom side of the hull by drilling holes. Because of this positioning, such transducer mounts produce the best visuals when connected to a quality fish finder. These mounts can either sit flush with the hull or project outwards into the water. When projecting out, they need a fairing block to keep them properly aligned.

The only constraint with through-hull transducer mount is that it should be mounted in front of the propeller, rudder etc. or the aerated air will interfere with the performance of the SONAR.

Through-Hull Transducers

4. Tilted Element transducers:

Tilted Element Transducer mounts are mounted much like the through-hull transducers. They are mounted flush on the underside of the hull and projected into water. But they don’t require a fairing block because the element inside the transducer tilts and levels itself to always direct the SONAR beam downwards.

Tilted Element Transducers

Based on the deadrise of the hull of your boat, you may select between a 12° version or a 20° version of the tilted element transducer. 12° is for boats with 8°-15° deadrise and 20° is for boats with 16°-24° deadrise.  The constraints for mounting and the performance are same as through-hull transducers. 

How to read a Fish Finder screen?

The fish finder sends down sound waves which reflect back from obstacles on the way. The center of the fish body reflects more waves than the head and the tail. So fishes end up being represented as arcs. The size of the arc gives you the approximate relative size of the fish. With practice, you can even identify the type of fish. Other objects like submerged logs tend to look more like solid lines since they are more substantial.  A group of arcs may represent a school of fish or it could be underwater fauna. This is where detailing is important in fish finders.

In traditional fish finders, when you are moving, the SONAR echoes also move from right to left. So, the object on the right side of the screen are the latest ones that just passed under you. If you are stationary, the screen will still move but it will show the same reading go right to left over and over again. 

Some of the SONAR waves will go and hit the bottom. If it’s shown in lighter colors, it’s a soft bottom. Hard bottoms will show up as one deeply-colored line as SONAR waves cannot penetrate these.  

How To Read Fish Finder

- How to Read a Garmin Fish Finder Screen?

- How to Read a Lowrance Fish Finder Screen?

What is a CHIRP fish finder?

The CHIRP fish finder uses the CHIRP (Compressed High Intensity Radiated Pulse) technology. To explain this, understand that traditional SONAR fish finders use 1, 2, or multiple distinct frequencies to red underwater objects.  Of these the lower frequencies like 50 kHz give the highest penetration but the lowest detailing. 200 kHz frequency gives great detailing but low penetration.  

A CHIRP fish finder transmits a long pulse over a range of frequencies at a time instead of a single frequency pulse like traditional fish finders. For example, it will send 130-210 kHz pulsing putting more energy into the water column. This gives you both excellent penetration and detailing. The CHIRP pulses are usually 10 times longer in duration than the traditional fish finder pulses. 

There are three CHIRP frequency ranges:

  • High CHIRP: 150-240 kHz for fresh water and inland fishing within 600 feet range
  • Medium CHIRP: 80-160 kHz for more coverage and quick scanning at lesser detail than High CHIRP
  • Low CHIRP: below 80 kHz for up to 10,000 feet underwater.

CHIRP fish finders are available in a large price range. The features of the premium units include:

  • Dual Channels: Such CHIRP fish finders have two transducers for two frequency ranges. You can choose between them based on species, depth and your fishing style
  • Custom frequencies: It allows you to use CHIRP as a traditional fish finder with the frequency fixed at a single point within the CHIRP range. You can manually adjust the frequency if you are looking for a particular species at a certain depth.
  • Transmitting power: You get adjustable transmission power from 300W to 4000W RMS. The affordable ones are usually 500-600W RMS.

You can find a lot of best fish finder under 200 with Garmin fish finder brands.

They have a superior customer service to both Lowrance and Humminbird. Garmin is known for their distinguished CHIRP SONAR which performs a sight better than Lowrance and the clarity of their displays.

4. Raymarine

Raymarine is another long-reigning brand of fish finders. They have some very popular units like the DragonFly. They used to be infamous for their non-responsive customer service but that has changed since they were acquired by FLIR systems in 2010. Customers have better access to customer support now. The screen and detailing of the Raymarine display are noteworthy. They are quite in demand in the UK as it’s the homeland of the company. They have grown more conservative with the prices to compete with Garmin and Simrad.

Garmin has been giving the Raymarines a run for their money since they came to the market. They are relatively easier to use.

5. Furuno

Furuno is known to make fish finders that are built like a tank. These are high-quality units that easily last for years without needing any upgrade. They have a limited but pretty high-end line-up starting at $500. These are built solid and prepared for rough use. The closest competition to Furuno are expensive Garmin fish finders. Furuno stands by their products and offer excellent customer service, a strong suit of Garmin. They also have very graphic and vibrant displays.
