Ice Fishing Sonar Fish Finder

About Ice Fishing Sonar Fish Finder from A Fishing Expert!

When you go fishing on a winter in river, lake, or ocean, you can locate the fish under ice by using a device called an Ice Fishing Fish finder. It is a sonar instrument which emits sound pulses below the surface of the water. The mechanism of operation of the sonar is quite simple. The device due to the processing of the received ultrasound displays information on the screen.

Using the sonar on ice, you can easily find that part of the lake where many fish live. Thanks to the fish finder, fishing will appear before you in new colors, because it will become like a real scientific expedition. Once the sound pulses reach an object or fish, sound energy reflects off them and goes back to the fish finder.

Ice Fishing

As the reflected sound energy comes back, the fish finder conducts a series of measurements which determine the location and depth of the fish under the water. The fish finder can also tell you basic information about the water like its total depth and temperature. The graphical display will give you a clear visualization of all this information.

Modern fish finders are a lot more advanced than they were a few decades ago. Now they have innovative technological features like GPS systems, marine radar, and colorized displays. There are even ice fishing fish finders available too.

With this information at your disposal, you’ll never have to guess where the fish are swimming in the water anymore. As a result, you’ll be able to catch a lot more fish and impress everyone you know.

Ice sonars are designed for ice fishing in freezing temperatures, while regular fish finders are designed for fishing in lakes, rivers, and oceans with normal temperatures.

Ice sonars can withstand freezing cold temperatures more than regular fish finders. If you were to use a regular fish finder in ice-cold water, it would either perform poorly or suffer permanent damage. Ice fish finders are made from a durable material which protects it from the cold.

How to Choose the Good Ice Fishing Sonar?

The probability of a large catch is directly dependent on the fish finder model that you will use. In the selection process, great attention should be paid to the power of the transmitter and the resolution of the display. If the transmitter power is high, this ensures accurate data on the status of the underwater depths.

Don’t just run out and purchase the first ice fish finder that you see in the store. You need to understand the essential features of an ice fish finder and how they can benefit you.

Consider the following features before you make your choice:

Portable or Fixed Sonar

Do you want a fixed or portable ice fish finder? In the age of modern convenience, most people will want a portable ice fish finder. They are lightweight, affordable, and easy to carry around on fishing trips.

On the other hand, fixed ice fish finders are more expensive, heavier, and less convenient. You don’t even have the freedom to carry them around. They require you to attach them to a boat or watercraft. That means you’d need to purchase a boat too.

Therefore, the good choice would be a portable ice fish finder.

Display of Sonar

The display screen shows you the information and radar of whatever is going on under the snow and ice. You’ll be able to tell the difference between the various objects in the water as well. This will reduce your chances of catching a piece of debris instead of a fish.

The good ice fish finders have a backlit display, so you can see the screen better in dimly lit areas. Then you can go ice fishing in the early morning and late afternoon without any vision problems.

Color or black and white

Most modern models come with a full color display, but with a monochrome presence on the market.

Black and white screens:

•   Low energy consumption;

•   Great for beginners;

•   Guarantee excellent contrast in bright sunlight.

Color displays:

•   Help identify all water bodies;

•   Permission to fully display the bottom topography / terrain map;

•   Simplify the process of finding the right fish.


The transducer beams sound waves into the water underneath the snow and ice. That is how fish are detected.

You must pay attention to the beam angle of the transducer because it can have a profound effect on its scanning range in the water. A big beam angle is suitable for scanning a larger width of water but without much depth. A small beam angle is suitable for scanning a narrower width of water but at a much greater depth.


GPS navigational systems can be found in many of the newest ice fish finders. They let you see an entire map of the water area and the locations of where fish are detected. You can mark those spots on the map so that you can go back to them later.


The transducer is what scans the water for fish. But you may elect to have an alternative scanning feature in your ice fish finder, such as sonars or flash technologies. Both serve the same purpose in scanning the water for fish and pinpointing their location.

Does it Memorize the Good Spots?

The newest ice fish finders have memory storage capabilities, especially if there is GPS technology included. It’ll remember where the most active fishing spots are located so that you can go back to them in the future.

Is the Fish Finder Waterproof?

Ice fish finders are not entirely waterproof. You can stick their transmitter in the water because it’s meant to be there. However, the receiver of the ice fish finder cannot be in the water. There are specific models which can withstand water splashes and mild submersion, but they cannot go too deep in the water.

Ice Fishing Tips and Tricks

• Protect the battery from cold. It is best to carry a working and spare battery in an insulated bag.

• There are two ways to use the sonar: freeze in ice or place the sensor in a hole. Each of the methods has its own characteristics, so experiment with the placement of the converter.

• Refuse the automatic mode of recognition of fish – in winter this function is less effective.

• Due to the static placement of the device, determining the topography of the bottom will not work, so fish in familiar water bodies.

• Choose devices prepared for frost. Winter echo sounders, guaranteeing trouble-free operation even at -70, can be found at Garmin, Lowrance, and Humminbird.

An sonar is a useful device that facilitates the search for fish even in an unfamiliar pond. With it, you can analyze the bottom, use suitable gear, track the reaction to the bait. For maximum catch, you must correctly select the echo sounder (screen type, number of rays, method of application) and configure the device.

If you follow our advice, even the first acquaintance with the sonar will be successful, providing you with a good catch. Good luck!
