Few leisure activities are as reliant on proper equipment as ice fishing. Not only do you need to keep yourself safe and comfortable, but you also want to ensure that your trip out onto the ice is as productive as possible.
Ice fishing is an activity that involves a big investment in time and can get quite physically demanding. Hence, it is doubly important to do whatever you can to ensure a rewarding catch.
Fishing gear manufacturers are constantly outputting new products to aid fishermen who won’t let a bit of freeze get between them and their bounty. One of these is fish finders. These are sonar devices that fishermen use to scan the watery depths below. Also called ice fishing flashers, these tools help anglers find the most productive areas to fish.

Ice Fishing Fish Finders – Buyer’s Guide
Fish finders offer a very wide spectrum of functions. Even the most tech-savvy fisherman may find themselves overwhelmed with questions. If you are new to fish finding technology and looking to buy your first unit, here is a breakdown of the important factors to consider.
Types of Fish Finder
- Traditional fish finders: These devices typically gather information about the conditions beneath the water surface and display it as a graphical representation of the physical reality. Along with information like water depth and temperature, they also display underwater structures, vegetation, and fish. These types of finders are most commonly used on boats but they can also be mounted on other structures.
- Fish flashers: These are quite rudimentary in design and the information displayed is typically limited to three data sets: The depth of the fish, the depth of your lure and the depth of the water directly below you. These units are simple to use but extremely effective. Flashers are appreciated by many anglers who prefer to keep things simple and don’t necessarily want to interact with a wide range of functions. Flashers are usually the most popular choice amongst dedicated ice fishers, although they are also widely used by those who do any kind of deep water vertical jigging.
- Castable finders: Castable fish finders are extremely portable and designed to be integrated with a smartphone or tablet. Before you start fishing a specific spot, this type of fish finder is cast into the water and reeled back in. As this happens, the unit builds an underwater map of the area which is then displayed on the mobile device. Popular amongst shore fishers, castable finders are the most portable of all the devices on the market. If you value a device that accommodates frequent moving or long treks across the ice, this is the product for you.
If you regularly fish in remote spots that may be tough to find on a subsequent trip, consider a unit that has an integrated GPS. This is an especially extremely useful feature when you need to “mark” a particular area on the ice that has no distinguishing features visible to the naked eye.
Display Quality and Flexibility
When opting for a traditional finder, you’re always going to want the best display component that falls within your budget. The quality of a fish finder’s visuals is directly related to its effectiveness. This is especially true for units that have a large amount of on-screen information visible at one point.
Do not skimp on this feature; it is one of the most important considerations. If you can afford a device that has a larger screen with a better resolution than a cheaper model, don’t hesitate to buy it.
Another display factor to bear in mind is how visible the display colors will be under varying overhead conditions. Some finders do not offer configuration in this regard, meaning that the on-screen data may be perfectly visible at night, but hard to read in harsh sunlight.
For an ice fisher that also does a lot of boat fishing, a traditional fish finder that can emulate the functionality of a flasher is often a good investment. This may come at an additional cost, but the versatility this offers is definitely worth the price.
The weight and dimensions of a fish finder plays a very important role in the ice fisher’s day or night on the ice. Traveling long distances on foot with a large collection of gear can get tiring, and the last thing you want is for your fish finder to be too cumbersome.
This is obviously quite a subjective factor since some anglers may be quite comfortable carrying a large device around with them, or some may use an ice fishing sled to carry heavy gear. Still, portability is not something that should be overlooked.
If it’s within your budget, consider opting for a unit that offers CHIRP technology in its transducer. CHIRP is next-generation tech that emits a pulse containing a very wide variety of frequencies as opposed to the single, double, or triple pulse that is offered by many finders. CHIRP sonar results in imagery and data with much higher accuracy.
The sonar signal that a transducer emits to gather information on the underwater world can either be ideal for high accuracy, or depth of penetration. A fish finder that offers flexibility in this regard is obviously ideal, but some anglers may not have the budget for such a device.
If this is the case, it is important to consider the following: Lower frequencies are better for depth, while higher frequencies are better for detail. While greater detail should always be the goal, this may not be possible your finder is exclusively built for performance in deeper water.
A Quick Note on Reading Fish Finders
All fish finders will come with a manual that will show you how to read a fish finder. Since there are many types and each unit has its own unique display, it’s best to consult the unit’s documentation or search for additional online documentation.
While many fishing purists will insist on using their instinct or that involving technology compromises the essence of fishing, there’s still no feeling like reeling in a big one.
Fish finders allow ice fishers the opportunity to do what they love best: going home at the end of a hard day or night on the ice with a trunk full of fish.
More and more fishermen are turning to technology to help them make the most of their time on the ice. Isn’t it time you do the same thing? If a fish finder isn’t for you, an ice fishing camera is another great way to find fish underwater.
