How To Choose The Best Ice Fishing Flasher – Buying Guide


An ice fishing sonar system is an investment that doesn’t come cheap. To ensure you pick the best ice fishing flasher for the money and end up with a unit that will serve you well on the ice, ensure the sonar device you go for meets the following requirements:


This is a piece of equipment you will want to have with you as you move from ice hole to ice hole and it should be easy to carry. It shouldn’t be so large and heavy that it is difficult to carry, weighs you down, and ruins your balance on the ice.

A compact and lightweight unit and battery that you can carry easily in your pocket or a small carry case and hold in your hand comfortably are the best. It will also be easy to transport to and from your fishing site. If it comes with its own ice fishing flasher bag, the better.


Ice fishing flashers rely on batteries to operate and battery performance is another important consideration to make. Choose a unit with a battery life that is long enough to last for as long as you will be fishing. The last thing you want is a battery that dies just when a big game is approaching your jig. All the gadgets in our ice fishing flasher reviews have excellent battery lives.

Made for Cold Weather

This is a device you will be using in sub-zero temperature conditions and it should be cold weather resistant so it can offer reliable performance and last a long time. Ensure that the flasher you choose is designed for cold weather and equipped with an ice ducer made for cold weather. Regular fish finders that mount on boats or kayaks can’t perform well or last in the ice fishing environment.

Backlit Display

If an ice fishing flasher is going to be useful out there, it should be easy to read in all conditions. Ice fishing is a winter activity and low light conditions are typical. When it is gloomy with little natural light, a backlit display ensures you can easily the screen so you’re not squinting and struggling to distinguish between the objects displayed.

Cone Size

The cone size tells you how far around and how deep the sonar beam reaches when it travels through the water. It determines the area size and water depth the transducer is able to scan and how much detail it is able to pick up.

A narrow cone size means a narrow beam that travels deep down and is ideal when you’re targeting fish that are deep down in the water and want to pinpoint targets. A wide cone size spreads over a wide area and doesn’t pick a lot of details. An ice fishing sonar system with a dual beam system is the best as it offers you the best of both cone sizes.


The transducer is the main component of an ice fishing flasher. It is the unit responsible for scanning the water beneath the ice and transmitting signals. It emits sonar waves that travel through the water and bounce off objects. What is underneath the ice is then displayed on the screen using colors.

Ensure that the ice fishing sonar you go for is equipped with a good quality transducer that can stand the extreme cold and transmit clean and clear signals accurately pinpointing targets even at deep levels. A flasher with a universal transducer holder system allows you to use it with a variety of ice ducers.

The power/wattage output of an ice fishing flasher affects its performance. The higher the power, the stronger the sonar waves and the better the performance of the sonar unit in detecting and displaying targets underneath the ice.


Frequency refers to the number of pulses of energy that leave the transducer per second and travel to the bottom of the water body. It determines how wide and how deep an ice fishing flasher will be able to scan. A high frequency gives you greater detail and better target resolution when ice fishing. A dual frequency transducer that offers both a high and a low frequency is the best as it allows you to choose the ideal frequency for the kind of coverage and details you want.


A compact flasher that you can comfortably handle on the ice is the best. It is also convenient for storage and transport as it fits in a small space. You don’t want a unit that takes too much space or is awkward to manage as you fish. 

Screen Resolution

The information collected by the transducer is displayed on the flasher’s screen. This makes screen resolution an important consideration when choosing an ice fishing flasher. For a clear and crisp display, go for a unit with a high-resolution screen. A larger screen size with a high number of pixels offers the best visibility so you won’t find yourself struggling to figure out what it is you’re seeing.

After a while, you start wondering whether there are any fish around. Should you continue working your jig the same way or vary the movement? Should you move on to a different ice hole or continue trying the same spot?
