Types of fish finders

A fish finder uses sonar to scan an underwater area for objects. The sonar data creates a representation of the underwater area on a display screen. You can find the bottom of the lake, underwater plants where you can hook the line, and of course fish.

Ice Fishing Fish Finder

Because there are so many different fish finders available, you can surely find one that meets your needs. But first, it helps to understand a little about the two main types of fish finders: stationary and portable.

Fixed fish finders

  • A fixed fish finder is permanently attached to a boat.

  • Some stationary units are permanently bolted to the edge of the boat.

  • Others are permanently fixed to the bottom of the boat, sending the sonar through the hull.

Portable fish locator

  • A portable fish finder can be moved from boat to boat.

  • You can also use it during ice fishing and when fishing off a pier.

  • Some portable units are attached to your boat with a suction cup. Notably, this is … not as stable as a fixed mount.

  • You may have to adjust the position of a portable unit & rsquo; numerous times to get the exact angle you want.

How does it work

Unless you understand that your fish finder works, you could end up spending the day fighting electronics instead of fish.

The science behind it

A device called a transducer sends sound waves into the water. As the waves hit an object & nothing; like a fish or the bottom of the lake & nothing; they are reflected back to the transducer. The software measures the speed at which the waves return, calculating the distance to the object. It then converts this data into a graphical representation on a display screen.

How it looks

There are two main display options.

  • Arc display: This screen represents lines and arcs where you have measured objects. You must decipher the lines yourself, figuring out which returns represent fish. With a full color display, returns that have a stronger signal (indicating a larger object) will be darker in color.

  • Fish identification display: Some fish identification units will display the shape of a fish or plant on the screen. When a fish identification unit displays a fish shape, the unit’s software interprets the data for you.

The fish identification option could lead to some errors as the data could be misinterpreted by the drive. For example, you can perceive a series of plants as a school of fish. But with the arc screen type, you may be able to tell the difference for yourself after getting a little practice reading the screen.

Fish search technology

Although easy to use, fish finders are quite complicated when you delve into their technology. To get the most out of your fish finder, it helps to understand the mechanics involved.


As mentioned above, a fish finder has a display screen on which you see its sonar “map.” The quality of the screen plays a key role in the enjoyment of the device. A sharper screen makes it easier to see the depth of the water as well as any fish in the area.

The average screen resolution is 250,000 pixels. Higher resolution (that is, more pixels) produces better display quality. To calculate the resolution, multiply the number of pixels vertically and horizontally.

In addition to a higher resolution, it is preferable to have a screen that is large and bright. A bright screen is easier to see in sunlight, and a large screen is easier to see from a distance. Like a television, the screen size of a fish finder is measured diagonally across the face of the screen.


Measuring the frequency of a fish finder, It is given in kilohertz (kHz). Some fish finders use multiple frequencies; others are limited to just one. The available frequencies are typically between 50 kHz and 200 kHz, although units with other frequencies can be found.

Frequency measurement helps determine how and where the unit can be used.

  • Low frequency drives work best in deep water.

  • High-frequency drives excel in shallow water, where underwater plants can be seen.

  • A high-frequency drive produces a sharper screen image than a lower-frequency drive.


GPS, short for Global Positioning System, plays a key role in fish finder technology.

You can use GPS to mark the points where you were successful today, and the Fish Finder software will help you find those points next time.

Some fish finders include bottom maps and charts for multiple lakes. You can use your fish finder’s GPS system to navigate the lake without losing your way.


The power of a fish finder is measured in watts (W). A high watt unit creates sharper readings in deep water than a low watt unit. Higher-powered units also respond faster.

A general rule of thumb is that you can receive about 200 feet of reading depth for 100W of power at a 100-kHz frequency.

If you double the frequency, you will receive half the depth of reading for those same 100 watts. And at half the frequency, you can expect to roughly double the depth of reading to 100W.

Energy sources

Different fish finders use different sources of energy.

  • Some run on rechargeable or alkaline batteries.

  • Some may plug a lighter into the dashboard of the boat.

  • Some connect directly to a fishing motor battery with alligator clips.

  • Some cables directly into the boat’s electrical system.

Make sure you can meet the power needs of a particular fish finder before purchasing. For example, if you don’t have a trolling motor, you probably don’t want to buy a fish finder that requires it.


A transducer sends and receives sound waves. The transducer included in the fish finder device determines the angle of the cone. (Think of the angle of the cone as the direction and width of the signal the transducer sends.) A narrow cone angle could be 10 degrees, but some have cone angles as wide as 60 degrees. A 20 degree cone angle is standard for many fish finders.

By using a wider cone angle, you may lose some sensitivity in deeper water. Some fish finders allow you to swap multiple cones.

  • Commonly, a fixed transducer will be mounted on the edge of your boat. Some more expensive models work through the hull of the boat.

  • With a portable fish locator connected with a smartphone app, the transducer is placed directly in the water. The transducer may have a float to prevent it from sinking.

  • Other portable units connect to your fishing line.

Types of sonar

Fish finders offer three types of sonar.


This sonar is focused strongly downward, making it work better in deep water than shallow water. In deep water, it can generate sharp images.


Both downscan and broadband (see below) are available together on some fish finders. This is a great option, and luckily, the price of these combo units is on the decline.


Also called a side scan, the broadband sonar works at an angle to the boat, allowing you to see the water undisturbed. It doesn’t work as well in deep water as the side scan.

The newest type of broadband sonar is called CHIRP, which uses a type of pulse that produces extremely accurate results. Pairing a CHIRP wideband sonar with a high resolution display is a strong combination.


You can expect to pay between $ 50 and $ 500 for a fish finder.

A simple portable fish finder will cost less. However, if you’re looking for a mountable fish locator with strong signal quality aimed at professional anglers, you can expect to pay several hundred dollars or more.

The extra and hidden costs with fish finders are minimal. However, you may have to pay for a professional installation if you are uncomfortable drilling holes in the boat yourself. And you may incur costs along the way for battery replacement. Some fish finders need a waterproof cover, too, depending on where they are mounted.


  • Before you go on a long fishing trip, you’ll want to get some practice done with a new fish finder. Take it to a nearby lake and test it for an hour, learning what the screen looks like. If you are using a display arc, this is especially important, as it takes some practice to learn how to interpret the data correctly.

  • For best results in shallow water, consider using a dual-beam transducer to cover more area.

  • A thicker line on the screen showing the bottom of the lake represents the hard, non-porous material of the lake bed. With this information you can find out which fish will be in the area.

  • The fish finder displays the scene from right to left as it moves through the water. Recent results are on the right.

  • Remember that if you buy a fish finder that interprets the data for you (for example, it shows the shapes of the fish on the screen), it could make some mistakes. These units sometimes read plants like a school of fish and vice versa.

Ice Fishing Fish Finder


You will come across many flashing ice fishing lights and figuring out which one to choose can be daunting. Choosing the right fish finder for ice fishing requires careful consideration of a few crucial factors to make a smart decision in terms of functionality and value. Here’s what to look for in choosing the best ice fishing fish finder that will serve you best when you’re on the ice .


For added convenience, you’ll want to carry your fish finder while walking on the ice so that you can discover new drill points. In addition to having the essential features, the best ice fishing fish finder needs to be lightweight. It shouldn’t be so heavy that it weighs you down and ruins your balance on ice.


The transducer is responsible for scanning the water under the ice and generating signals. Its beam angle is another important consideration to take into account when choosing an ice fish finder radar. The angle of the cone tells you how far the sonar beam spreads as it travels through the water.

The angle affects the size of the area and depth of water that the transducer can scan and the amount of detail it can capture under the ice. Small angles mean a narrow beam which is ideal when targeting fish that are on the bottom of the water and I want finer details. Larger angles can scan a wide area but are not very detailed.


Your ice fishing fish finder’s display should be easy to read, whether it’s bright and glare or you’re fishing in low-light conditions in the morning, at night, or during gloomy winter days. A backlit display makes the information displayed on the screen clearly visible and allows you to distinguish between objects under the snow no matter what the conditions.


A compact and lightweight fish finder that you can easily carry in your pocket, in a case and hold in your hand comfortably is the best. Carrying heavy things while walking on ice can drag you down and even cause you to lose your balance and fall. The battery should also be compact and lightweight.

Portable Ice Fishing Fish Finders are the ideal choice for comfort when jumping from hole to hole. The downside is that the screen will be smaller and it may be more difficult to see the information displayed. Larger electronic ice fishing devices offer more features and functionality and are more accurate, but will be larger and heavier, making them cumbersome to carry.


The best electronic ice fishing devices are well built to withstand extreme cold conditions and transmit clean signals for a long time. The quality of the transducer generating signals is a very important consideration, as it affects both the quality of the readings and the overall durability of the unit. A fish finder designed for ice fishing will also offer more durability as it is equipped to be cold weather resistant and provide reliable performance even in freezing cold conditions.


Power affects the clarity of readings and higher wattage / power flashing ice fishing lights will give the best performance when detecting what is under the ice. More watts generate faster reads, while fewer watts mean slower reads.

Battery life is another important consideration. Choose a unit with enough battery life to last you while you are fishing . You can also have a battery backup just in case.

Simple fish finders do not require a large amount of battery power to operate and have a compact battery. Larger units have more features, but battery life tends to be short.


In addition to the beam angle of the transducer, the area and depth that an ice fishing fish finder will be able to cover will also depend on the frequency of the beam. Frequency refers to the number of pulses of energy that leave the transducer per second and travel to the bottom of the body of water.

The higher the frequency, the more details you get. You can differentiate a single fish from a school of fish. High frequencies like the typical 200 kHz are very effective at shallow depths. Low frequencies, such as 50 or 83 kHz, work well in deep water and wider areas, but they don’t convey much detail.

There are single, dual and multiple frequency fish finders that give you multiple frequency options so you can select the ideal frequency for the type of coverage and details you want.


The number of pixels will determine the screen resolution and the quality of the information displayed. A larger screen with lots of pixels offers the best visibility of even the smallest details under the ice. Choose an ice fishing fish finder with a high resolution screen to enjoy a crisp and clear display of information and image representations. With it, you won’t have to struggle to figure out what you’re looking at.


The material from which the transducer is made is an important consideration as it will affect the quality and durability of the unit. Plastic is a common material, as it is weather resistant and does not absorb water. This is good in a unit that will be used in extremely cold conditions. There are also transducers made from fiberglass, stainless steel, bronze, and even wood.

Frequently Asked Questions When Buying Ice Fishing Trackers

Q: What are the advantages of using a fish finder?

When ice fishing, the biggest challenge is not knowing where the fish are. There is only a vast expanse of snow-covered terrain around it. Relying on chance can waste time drilling holes that yield no catch. Using a fish finder allows the angler to enjoy the following benefits

Find out where the fish are

A fish finder gives the angler the advantage of being able to identify where the fish are and therefore the best place to drill a hole and cast a jig or set a baited trap. This increases the chances of catching fish and saves ice fishermen a lot of time.

See Beneath the Ice

Another advantage of using a fish finder is being able to see what is happening under the ice. Using an ice fishing finder, the angler can see the layout of the water, the bottom structures, and the depth where the fish are found.

Study the fish

The angler can also observe how the fish behave under the surface and how they interact with the lure. The angler can try different jigging actions to attract the fish.

Memorize the Best Spots

Most fish finders are able to store information about the best places to fish, making it easy to remember and locate the best places to fish on subsequent trips.

In general, using a fish finder makes ice fishing excursions easier, more successful, and more enjoyable.

Q: Are all Fish Finders waterproof?

All fish finders are not fully waterproof. Fish finders are used in and around the water and it is inevitable that they will splash in the water or even get completely wet. Water is an enemy of all electronics and fishing electronics is no exception.

To equip them to resist water damage, fish detectors are designed to resist water intrusion and are equipped with water resistance up to a certain depth of water pressure and for a specified time beyond which the water will penetrate. For example, a waterproof IPX7-rated fish finder is waterproof to 1 meter (3 feet) or less for 30 minutes or less.

However, no fish finder is completely waterproof. They will be able to withstand splashes, rain and accidental wetting, but they are not equipped to withstand submersion at any depth or for extended periods. With most fish finders, the transmitter that is intended to be exposed to water and ice will be waterproof, but the receiver (the unit with the display) will not be waterproof, see the details page from your fish finder to get information on its water resistance level.

Q: What is the difference between a normal and an ice fish finder?

The difference between a normal fish finder and an ice fish finder is that an ice fish finder is designed to work reliably in extreme cold conditions. They are made of materials that adapt to cold weather, they use a system color-coded to show what’s underneath the slow ones and use intermittent technologies that work in extreme cold. Most regular anglers are not equipped for use in cold temperatures. They have no protection against snow and cold. Low temperatures will affect performance or damage normal fish electronics.
