Best Ice Fishing Finder – Flasher quality, sonar outreach and depth finders reviewed

Hello! It’s me again, Thomas, your friendly neighborhood fisherman! Today in King of the Catch, I will be talking about some of the best ice fishing finder I have used. I have been Ice Fishing for decades now, and this is the only activity that I could spend doing in the freezing cold for several hours. ūüėČ

Best Ice Fishing Finder

A fish finder is crucial to your ice fishing experience as it will determine how easily you can detect your prey-the fishes! It is the device that you use to sniff out which areas the fishes prefer, whether they are in shallow or deep water, how much frequency of sound waves you need to detect them and so on.

I have curated a list of tried and tested best ice fishing finders taking into account factors like ¬†–

Here is a quick overview for  best ice fishing finder:

Garmin Striker 4

The Garmin Striker 4 takes the crown for Editor’s Choice owing to its high-end features at an affordable price. The CHIRP technology is the cherry on the cake!

Firstly, Striker 4 is compactly designed and makes it portable, especially if you are in a small boat. Another spot-on feature it has is the GPS feature. It can detect both speed and depth and give you a rounded experience. Striker 4 also has a CHIRP Sonar transducer, which boosts the clarity of visuals on the screen.

It also has features that show water temperature and boat speed. The buttons are clearly defined. The keypad is also spacious enough for easy control and access, even when you have gloves on. It has a waterproof rating of IPX7. This means it can stay in water for up to half an hour at a depth of 1 meter.


  • ¬† ¬† Display

The Striker 4 has a 3.5″ touchscreen with a full-color display. The screen allows you to see the images detected at different frequencies. The thing with frequencies is that the lower you go, the lower your sensitivity should be if you want a clear image. The highest frequency is 200 kHz and provides a clear image. The lowest frequency reading on this device is 77 kHz; on the other hand, it will give you wider coverage. The image quality is very crisp. Although it has a small screen, space is enough to display the target, the lure, and the bottom structure

Personally, I prefer using a higher frequency because of the sharp image it gives. However, if you have to use the lower frequency, the additional hardware that comes with the Garmin Striker 4, such as the cables will help you get a detailed and precise image.

  • ¬† ¬† GPS

The built-in GPS can not only help you with detecting fishes but also mark your fishing hotspots so that you can come back to it later. It also has the option to view the information in a flasher style reading.

  • ¬† ¬† CHIRP Technology

The CHIRP technology is one of the finest techniques available to show you what lurks underneath the water. The Striker 4 is one of the affordable Fishfinders that has this technology. Sonar devices use signals to understand the underwater activity.

So, for understanding what happens at deeper levels, one needs low frequency while the high frequencies are required in order to understand what happens in shallow water bodies. Typically sonars have only one frequency limiting access to water depth and image clarity.

What makes the CHIRP sonar different is that it can alternate between signals and frequencies to help you see high-resolution images of small objects and structures at the bottom of the water body.

  • ¬† ¬† Modes

The Striker 4 has six modes. Each mode displays varied sections. The traditional mode shows the bottom structure and the objects. The flasher mode indicates the depths of the water bodies. It also adjusts the sonar frequencies in one display. The split-frequency mode shows the highest and lowest frequencies, that is 200 kHz and 70 kHz. It means you can see the beam cone areas that are way under your boat.

Marcum LX-7 Ice Fishing Sonar System/Fishfinder – LX-7

The Marcum’s LX-7 is one of the best ice fishing finder sonar. It has been built with the features of MarCum LX Flasher and digital fishfinder technologies. This is the device that will basically hunt down fishes for you through its highly sensitive sonar technology.

Not only this, but you will also get to see what is happening down under the water in vivid detail. The Marcum LX-7 provides an interactive experience through the 8-inch LCD screen.

It has four vibrant color palettes. The screen also has a dashboard that displays the battery voltage, gain, interference rejection(IR), digital depth, and target adjust. It also gives customized window views such as vertical zoom, flasher-dial, and traditional LCD graph displays.

The device can provide you images from 300 feet deep! It is  a premium option for ice fishing depth finders.

The Sonar Footprint Technology displays scan areas at 8 degrees or 20-degree transducer cone angles. It helps the user focus on the targeted fish, transducer, and lure. What’s more! You can even zoom in and out of the screen.

The LX-7 also has a target separation of ¬Ĺ” which is helpful for differentiating between objects underwater. The sensory data also helps you to target the object separately. The device also prevents neighboring sonar users from intruding in that area by avoiding the “footprint” area.

While using the Marcum LX-7, the only issue I had was moving between ice fishing holes. The auto-depth reading would get stuck at 1.3 feet. Later I found out that it was an issue of adjusting the sensitivity while at the bottom and turning it back up.

There can also be issues of fogging up and glare on the screen. To tackle this situation, you can use a screen protector which will not only solve glare problems but also protect your screen from damage.

Humminbird ICE 35 Flasher Series

The Humminbird Ice 35 Flasher is one of the best ice fishing finder that I would suggest to any ice fishing novices. It has an easy user interface and a powerful battery. It is one of the best ice fishing flasher for the money. You can detect where the fishes are under you, what size they are, and where to best place your fish lure. It also has digital readouts that make it friendly. It comes in a good looking case. The best feature that I found using the Humminbird ICE 35 Flasher series is its sensitivity. It would be great to have a single support cable, but it’s not an inconvenience as to hamper the flasher’s performance.

The dual-beam transducer comes with selectable options, and coupled with the 800 watts of power, it makes the ICE 35 Flasher a treasured fishing find. The flasher’s zoom feature and its ability to go up to 200 feet of water is a bonus. I often fish for lake trout in 120- 180 feet of water, and this flasher was the only model that went beyond 120 feet of water.

I use the Humminbird flasher by setting it up on an overturned bucket and dropping the transducer into the ice hole. Then I drop the ice jig and use the flasher to help me in deciding where to place the bait ideally. It’s effortless to use and plus points for the fishes that I have caught using this flasher!

Frequently Asked Questions

What do I look for while buying an ice fishing  finder?

It depends on factors like the  kind of water bodies you usually fish in, what type of fishes you want, whether you use a boat, kayak, your rod size, and so on.

Make a checklist of the factors that revolve around your fishing habits. Then, see which devices have compatible features that might enhance your fishing experience.

Accordingly, you can then narrow down your options. You may want to check out handy rods that pair up well with any kind of lures.

How do I determine what sonar accuracy is better?

There are three factors that determine how accurate a sonar is. First is the cone angle. It can range anywhere to 6 to 90 degrees. A broader angle will give you a bigger picture but sometimes that can give less depth. For shallow water bodies, a wider angle will give you a better view.

Whereas a narrow beam will help you for deeper waters.There are also options of transducers that combine two to four beams to give the best picture.

Second, the frequency matters.  Compressed High-Intensity Radar or CHIRP technology is one of the best. It helps you switch frequencies that are best for the situation.

Thirdly, the power of the device is important. It determines the frequency which in turn influences the cone angle. All three are interconnected. The minimum power you want for your device is 600 W. Anything above that will help you get clear readings and can also be used in deep areas. Y

ou need to buy batteries separately for the Garmin Striker You can use lithium batteries  for the same purpose. They are light and rechargeable.

 What should be my budget?

Depending on the type of fishes you want to catch, the features of the fish finder like display and GPS will be the guiding factor for your budget. If you are planning to splurge, make sure the features of the fish finder are appropriate for the type of fishes and the location you usually fish at.

Final Words

I believe in the statement that if one does not know what is going on underneath him in the waters, he can never have a good catch no matter what his strategy is. It is thus important to have the best ice fishing finders in your arsenal to have a good haul day!

I listed out the fish finders according to my experience, highlighting its best feature while also mentioning its drawbacks. I hope that this has been of help to you. Let me know which are your favorites too in the comments below!
