The Guide for Beginner about Fishing Flashers and Fish Finders

This article researches the essential characteristics and usage of the ice fishing fish finders and the ice fishing flasher. These two pieces of fishing equipment have very distinct functions and appearances, yet they fundamentally perform the same thing. 

How does a flasher work?

Ice fishing fish finders with a unique design are known as flashers. Its primary use is to show you what’s in the water column below your fishing hole and ignore what’s irrelevant. Put another way; they are designed for vertical fishing; flasher ice fishing requires precisely.

Traditional fish finders, unlike flashers, collect data from a large sonar cone that surrounds your boat. They may also scan large areas with side imaging while flying over water.

Flashers are more or less one-dimensional in their readout since they focus solely on the vertical water column underneath the fishing hole. As a result, its readout can be displayed as a single vertical line or circular display, which is the most frequent.

The presence of fish in the water column between the ice, the bottom, and the water depth and consistency are revealed by top flashers. You can’t see these fish without an ice fishing flasher, so you’re stuck catching fish at the bottom. A flasher will also display you where your lure is about the fish, allowing you to adjust its depth to match the fish.

How to read an ice fishing flasher?

Most flashers display color signals that indicate where the bottom is and how consistent it is. A firm bottom produces a more powerful and well-defined signal, whereas a soft bottom or weed bed produces a fuzzier, broader band. They also display your lure as you drop it through the water column and any fish that move across the sonar cone.

You’ll frequently be able to determine whether a fish is approaching your lure or jig, and you’ll predict when it will strike. You’ll also be able to determine whether fish are suspended mid-water in the column, and you’ll be able to present your lure at the same depth.

This makes flashers incredibly effective tools for increasing your chances of catching fish, but it also makes the experience more enjoyable since you can see the fish as you drop your jig down to them.

As you watch a fish approaching your bait on the screen of an ice fishing flasher, feel the tug when it grips the lure, and then reel it in, it’s always a thrilling experience. A top flasher will also alert you if a fish approaches the bait but then turns away. This will let you experiment with different lures to find which ones perform best for attracting a strike on that particular day.

Which one should you get? Ice fishing fish flasher or fishfinder

Traditional fish finders were meant to display historical data of what transpired in the sonar cone over a few minutes (hence the name 2D sonar).

Many manufacturers, however, are now producing ice-fishing fish finders with flasher capabilities. In other words, their display only shows current sonar waves from beneath the ice hole and excludes primary data (and this applies to all models discussed in this review).

As a result of this advancement, the performance of ice-fishing fish finders and flashers has become almost comparable. The one you select should be based primarily on personal choice.

Can you use your regular fishfinder?

Without a doubt, you may use a standard fish finder for ice fishing as long as you set it up appropriately with the transducer pointed vertically downwards. You can even shoot through the ice with a standard fish finder to search for fish before digging a hole.

On the other hand, a standard fish finder isn’t designed for ice fishing, so this option isn’t great if you regularly want to go ice fishing. It isn’t as long-lasting as a flasher, for starters. Second, the transducer must point down vertically from your fishing hole for ice fishing. If it points slightly to the side, you’re searching in the wrong place. Regular fish finder transducers don’t come with a sliding float to help you position the transducer correctly in the fishing hole, so you’ll have many problems doing so.

The ways to choose the best ice fishing flasher

Compared to normal fish finders, good flashers are a little more expensive, but they are particularly developed for the challenging circumstances of ice fishing. To choose the finest flasher for ice fishing, you must first understand what qualities to search for.

Here’s what you should be looking for:

High-performance battery

Because cold weather depletes batteries more quickly than hot weather, you should invest in a high-quality battery with a long charge life. Many combo packs include a battery, which is generally sufficient. You can also consider obtaining a lithium battery, which lasts twice as long as standard SLA batteries.

Portable design

Ice fishing necessitates a great deal of movement from hole to hole. As a result, your flasher and other accessories must be simple to pack and transport. Several firms have created carrying bags specifically because it allows them to transport their fish finders in a small pack that fits within a five-gallon bucket.


Flashers must be able to perform in sub-zero conditions and the presence of ice and snow. As a result, it’s preferable to use a flasher rather than a standard ice fishing fish finder because flashers are developed specifically for this demanding environment and survive longer with fewer flaws.

Ease of use

You must be comfortable with the flasher, including all minor changes you’ll need to make while on the ice. Because each model differs somewhat in settings and control options, you must select the model that appeals to you the most. In our experience, simplicity wins out over many features because it allows you to concentrate on what matters most: catching fish.

Transducer for ice fishing

The majority of the flashers examined here come with an ice fishing transducer. A transducer made for ice fishing will undoubtedly outperform a transducer intended for warm-season fishing.

The primary reason is that an ice transducer must be positioned appropriately to point down vertically into your fishing hole accurately. This guarantees that it is scanning the right area of water and not firing in the wrong direction.

Ice transducers are designed to be suspended from afloat, which allows them to be automatically positioned. Additionally, because the float position can be readily modified, the transducer may be aligned with the bottom edge of the ice, resulting in a more precise reading.

If you acquire your flasher during the summer, don’t try to test it out of the water (see our article “Can a Fish Finder Work Out of Water?” for more information).

Summer is the most fantastic time to test a new transducer from a boat or kayak. Also, if you’re bringing out your old ice fishing transducer for the first time this winter season and aren’t sure whether it’s still functional, check out our post on detecting if your transducer is broken.

Both the Fishing Flashers And Fish Finders are all gears with both positive and negative sides for fishing. Users will learn the benefits of each piece of equipment to best suit their fishing purposes. However, an ice flasher may be an excellent tool for individuals who wish to capture more fish. It’s also appropriate for novices because it doesn’t require them to be ice fishing experts or know what they’re looking at. It may provide you with the information you need without missing any specifics about your surroundings.
