Which ice fishing fish finders are best?

What to know before you buy an ice fishing fish finder

What is a fish finder?

A fish finder is a device that uses sonar pulse to create a real-time image of the lake or river floor underneath your boat. It utilizes a hull-mounted transducer to send out sound waves which then bounce off objects to create a detailed image of the area under your boat. This display allows you to see fish natural features in the water, as well as individual fish and schools of fish. 

If your tool comes with a depth finder, you can see how deep these features and fish are. The finder will also note the temperature of the water.

How to use

Modern fish finders do an excellent job of interpreting different transducer signals. However, you need to learn how to use the device to get the best results. You should also know which signals the transducer may mistake for other things. For example, your device may mistakenly read several underwater plants as a school of fish. This is why it’s important for you to be relatively familiar with the area where you’re ice fishing. 

Bring a charger

Consider bringing a portable pack with charging accessories since smaller fish finders tend to eat up battery power quickly. 

What to look for in a quality ice fishing fish finder


The transducer acts as the eyes and ears of a fish finder device. It’s like a submarine sonar, which sends out a ping and listens for an echo. The most common place to mount a transducer is on the stern of the boat. You should place it on a transom, shoot-through or through-hull. 

The transom is a flat section outside of the hull. It’s easy to place the transducer on this portion of the boat, but it increases the likelihood of interference due to the boat’s motion.

You can also glue the transducer on the inside of the hull, known as the in-hull or shoot-through. You should only try this with fiberglass hulls since it’s difficult to get an accurate reading with this setup on foam-sandwiched, aluminum or wood hulls. 

Finally, you can mount the transducer by drilling a hole into the bottom of the hull, also known as the through-hull. While the through-hull offers accurate readings of the water under the boat, there will be a permanent hole in the hull.


Modern fish finders have full-color screens with color-coded data, making it easy to figure out what’s under the boat. It will identify individual fish, schools of fish, clear water and contours of the sea bottom or lake. The screen can also give you extra info, including boat speed, water depth, water temperature and time.


High-quality fish finders incorporate a GPS to locate the position of the boat compared to other navigation points, like the docks or the shore.

How much you can expect to spend on an ice fishing fish finder

Ice fishing fish finders have a wide price range and cost between $99-$699. Handheld ice fishing fish finders with smaller screens only cost about $99-$179. Mid-range fish finders with 5-inch screens go for $254-$399. High-end fish finders with 7-9-inch screens typically cost about $499-$699.

Ice fishing fish finder FAQ

How do you improve your fish finder tracking?

A. If your ice fishing fish finder isn’t bringing back good data, try peaking the transducer. This technique will help you fine-tune the settings and give you a better picture of your surroundings even in poor conditions. There are three steps to peaking your transducer. First, change the fish finder range to three times the actual depth of the water. Next, increase the sensitivity until you can see a second bottom underneath the first bottom on the primary screen. Finally, slowly decrease the sensitivity until you have a good read on the first bottom result. Place the range back on its original setting and see if your readings are any better.

What does it mean when an ice fishing fish finder is running behind?

A. Your fish finder sends out a sonar pulse, which takes some time to return to your boat. If your boat moves too quickly, you may pass the spot you just surveyed. You may also miss the fish near your boat if your screen scrolls too slowly. If something intriguing pops up at the far right of your screen, boost your screen’s scrolling speed and slow down the boat to investigate.
