The device will provide you with the information you need on a dazzling bright screen thanks to the TrueColor patented MBC Brushless Lighting.

One feature that makes this product stand out is its ¾ inch target separation. On the ice, this level of sonar clarity will enable you to easily distinguish between fish and underwater structures. When you locate a school of fish, the technology will help you catch the biggest fish in the group.

Additionally, the device is equipped with a dual-beam transducer to provide users with a clear idea of underwater conditions. You can adjust the beam angle to focus on fish close to the lure by simply pushing a button. The device also features a patented zoom technology that can be moved all over the water column. This will provide you with the accuracy and freedom to hunt different species of fish.

Another patented feature in this device is the 12-step interference rejection system. This means that the device can be combined with a 200 kHz sonar or any other frequency.

How To Choose The Best Ice Fishing Flasher

Ice fishing is a tricky activity for both beginners and experienced anglers but fortunately, it can be simplified with the right gear. This is easier said than done though since several anglers don’t have the experience or time to search for the ideal ice fishing gear for their needs.

I’ve created this guide for anglers that are unsure of the features to look out for in an ice flasher:

Custom Display

Though most ice fishing flashers carry out the same tasks, there are some advanced models. In addition to providing basic information on underwater activities, the best ice fishing flashers utilize smart technology to improve the catch ratio of users.

For example, a fish flasher with a customizable display will enable you to choose the readings that you see on the screen. If you don’t have the experience needed to take advantage of this feature, you should opt for a model with easily readable default settings.

Transducer Quality

The importance of having a quality transducer can’t be overemphasized as most of the vital details will be delivered by it. It sends out the sonar waves and helps locate fish at great depths. Additionally, you should consider getting an ice fishing flasher that comes with a transducer holder system. This will enable you to use transducers of different sizes in the future.

Split Screen

The split-screen is a helpful feature that is usually found in devices with larger screens. An ice fishing flasher with a split screen will show two different modes simultaneously i.e. sonar mode and live underwater mode. This will give you a clearer idea of the activity of the fish and ultimately increase your catch ratio.


You will have to keep moving from ice hole to hole when ice fishing. As a result, your ice fishing tools have to be lightweight and compact. Most manufacturers include carrying bags in packages to make it easier for ice anglers to transport ice fishing flashers. These carrying bags also tend to fit inside five-gallon buckets.


Since you will be fishing at sub-zero temperatures, your ice fishing tools should be able to withstand extremely cold temperatures. This is a major reason why you need to choose a flasher over a regular fish finder. Ice fishing flashers are specifically built for the cold, so they last longer.

You just have to ensure that your device has the strength to withstand bumps on its way down the water column. It should also remain in good condition if it ever falls accidentally.


Most models are powered by batteries and this raises an issue as batteries drain faster in cold conditions. Hence, you need to opt for a high-quality, long-lasting battery. Several combination packs feature a battery and a charger, but you can get an extra battery if you want one. I would recommend that you get yourself a lithium battery, this is the best available.

Lighting and Resolution

Regardless of the lighting or weather condition, your ice fishing flasher should always be easy to read. You should ensure that your device remains easy to read whether it is sunny or cloudy. The screen should have a high resolution too.

Cone Size

The size of the cone will determine how far the sonar beam can travel and the area it can travel. Narrow cones produce beams that travel into the deeper parts of the water while the beams from larger cones cover wider areas. So, you should choose your cone size based on the type of fish that you are after.

Target Separation

Target separation simply refers to the ability of a sonar device to distinguish between two objects. The smaller a flasher’s target separation, the better it will be at distinguishing between two fishes or a fish and your lure. It is measured in inches.


You will need to make a significant investment to get a high-quality ice fishing flasher. But if you can afford one, you are guaranteed to get good value for money. The best ice fishing flashers are long-lasting and they will also ensure that you don’t run out of fish all winter.

What Are Ice Fishing Flashers?

An ice flasher is a fishing tool that is similar to an ice fishing fish finder. But while ice fishing fish finders show the different shapes below an angler, ice flashers feature clock-like circles. In a flasher’s circle, you will see the depth of the water increase in the clockwise direction. Shapes are also displayed close to the circle to depict underwater activities.

Ice flashers are highly suitable for vertical jigging and can detect even the smallest jigs. So, you will be able to place your bait at the exact depth that it is meant to be. The device will also tell you the depth that the fish is located. You will get to see the movement of the fish towards your lure or jig too.

Watch this video to learn some useful ice fishing jigging motions:

How Does an Ice Fishing Flasher Work?

Ice flashers operate with the aid of sonar technology and it allows them to detect objects beneath the ice. In other words, the depth of the water is measured using sound waves. The device is made up of three main parts, they include the power pack, screen, and transducer.

To kickstart the process, the power pack transfers electrical energy to the transducer. The energy is then transformed into sound waves by the transducer. After that, the sound waves are transmitted down the ice hole in form of a cone. Echoes will be generated as the sound waves collide with objects underwater and they will be picked up by the ice fishing transducer. Finally, the echoes are then broadcasted as signals to the screen.

Getting Started With Your Flasher

In this section, I’m going to explain the basics of using the device. Place the transducer inside the hole, let it be around a foot deep. After that, turn it on by switching to the first depth which is usually 20 feet. You will see a red bar if the device has been immersed deeper than 20 feet.

In such a situation, you will have to switch the device to the next depth range. Your goal should be to get only a few inches of red. The readings will change as the dial adjusts to the sensitivity of the ice fishing sonar.

Your fish flasher will tell you the location of your lure and the distance between the fish and the bottom of the water. It can also assist you in identifying your prey. Turn the device up when targeting smaller prey and vice versa.

After detecting the overlay depth scale, you need to know when the fish is approaching your lure. The interference rejection (IR) button will come in handy in this regard. It will ensure that your display remains clear and free of distortion. Another feature that you will find in some fish flashers is the zoom feature. It will enable you to magnify your view by at least five feet. You should watch out for these two features as they will make it much easier for you to find a favorite fishing spot.

How to Read an Ice Fishing Flasher?

After learning how to set up your ice fishing flasher, the next line of action will be to learn how to read it.

Your flasher’s screen will display vital information such as the bottom of the water body, your bait, nearby fish, and underwater structures. You will be able to identify each of these objects based on the color displayed. For instance, green bars will appear on your screen when the flasher is dropped in an environment with lots of vegetation. If you see green and yellow lines, it means that fish is nearby. Also, the fish is close to the bottom when you see red and yellow lines.

You will see the colors changing as your lure goes deeper into the water, so you will know when it reaches the bottom. A large red area will represent the bottom of the water column. I recommend that test your flasher in different ice fishing holes to get a better understanding of what the colors represent and how they can help you catch more fish.

Additionally, the most effective way to locate fish with a flasher is to find the bottom circumference and cone angle of the ice fishing flasher. These pieces of information will tell you how close the fish is to your lure. For instance, your cone will have a width of 5 feet when you fish in a hole that is 20 feet wide.

The width of the cone will change to 10 feet if you move to 40 feet deep hole. You will get a strong signal when the fish is directly under the fish flasher and the reading will feature a thick red line. On the other hand, you will get a weak signal when the fish is outside the cone. 

An ice fishing fish flasher is designed not just to show you underwater activities but to also tell you the perfect time to drop your lure. After detecting the presence of fish, you can trigger a bite by working your lure a little bit. The closer the fish moves to your lure, the thicker the line will become. This will be particularly beneficial as you will know the exact moment to use more force. You will also no longer have to waste your time guessing the location of the fish and when and how to react.

Evaluating the Condition of Your Hole 

You can also detect the hardness of the bottom of a fishing spot with a fish flasher. The importance of obtaining this information is that fewer fish are found at harder bottoms. If the line on your screen is completely red or you can only see thin green lines, it means that the bottom is rock hard and can’t be penetrated by the sonar. Soft bottoms are represented by wide bands and there are usually lots of fish feeding in such areas.

Additionally, you can get greater mobility with an ice flasher. To locate schools of fish, you will have to continue moving from one hole to the other. The device will help you check more ice holes in lesser time. Without a flasher, you will spend more time on each hole and you may not even find anything. A flasher will also make it easier for you to target various species of fish as you will have more time to switch your lures.

Here are some tips for safe ice fishing.

Frequently Asked Questions

What is the best ice fishing flasher?

The best ice fishing flasher for you will be a product that has all the features that you need for ice fishing. You can check my buying guide to learn about the right features to look out for in an ice fishing flasher. But if you don’t have the time to spare, I recommend that you get the Humminbird Ice-35 Three Color Flasher. It has all the features that you will need to catch more fish.

Are ice fishing flashers worth it?

An ice fish flasher will be an excellent investment for any ice angler, especially one that does lots of fishing in winter. Ice fishing flashers are designed specifically for ice fishing. They offer more value than ice fish finders because they provide real-time information on underwater activities at an impressive resolution.

Is an ice fishing flasher a necessity for ice fishing?

No, you can fish through an ice hole without an ice flasher. The primary tools that you will need are a fishing rod, hook, line, and lure. However, you will have no idea about the location of the fish or the depth of the water without a flasher. So, while an ice flasher isn’t a necessity, it makes ice fishing easier and more rewarding.

Is a camera better than a flasher for ice fishing?

No, an ice flasher is a much better choice when it comes to ice fishing. Underwater cameras are only effective when the lighting, depth, and water clarity are favorable. So, they have no use under a sheet of ice.

Can I use a regular ice fish finder for fishing?

A regular ice fish finder can be used for ice fishing, however, this won’t be possible without a conversion kit. So, you will have to buy one separately unless you own an advanced fish finder with ice fishing capabilities. Still, even the most advanced fish finders can’t match the performance of a dedicated ice fishing flasher.
