Things to Consider When Buying the Best Ice Fish Finders


Quality ice fish finders are more than capable of withstanding extreme cold and inhospitable conditions.

Ice fishing is conducted in extreme weather conditions, with temperatures commonly dropping to around 0-degrees Fahrenheit. Therefore, to stand the test of time, an ice fishing sonar unit must be pretty durable and up to the task at hand.


A fish finder must be lightweight to offer substantial appeal to ice anglers, who must transport their gear across the frozen water.

Ice anglers are typically required to tote their gear for lengthy distances to reach their destination. A large, bulky fish finder can make this task relatively challenging to tackle. However, using a lightweight alternative can save substantial hassle and make transport much more effortless.


The frequency of a fish finder plays a pivotal role in determining how such a unit will operate at various depths.

Fish finders come in numerous frequencies, all of which come with their own distinct set of advantages and disadvantages. For example, higher frequency units tend to be more accurate but are less effective when used in deep water. Likewise, low-frequency fish finders are capable of excellent detection in deep water but are less accurate in their representation of what lies beneath the ice.

Backlit Display

Some fish finders feature a backlit display, which simplifies viewing under highly bright or minimally lit conditions.

When the sun bears down, a sonar unit’s display screen can be difficult to read. Likewise, display viewing can be hampered by periods of low light. A backlit display limits such difficulties and makes it easy to decipher the information depicted on a sonar unit’s display, no matter the conditions at hand.


An angler must put much thought into how their fish finder will be powered to avoid the risk of facing decreased usage times.

When selecting a battery for use with an ice fishing fish finder, it is essential to keep portability in mind. A battery should be large enough to provide your fish finder with sufficient power for sustained use but should be light enough to be carried without much difficulty. Many manufacturers now market ice fishing-specific fish finder batteries that adequately meet the needs mentioned earlier.


As is typical of most electronic products, an angler often gets what they pay for when purchasing a fish finder of any type.

Realistically, most anglers cannot spend an unlimited amount of money to purchase the most refined sonar unit on the market. However, quality sonar units of one variety or another can be purchased at most any price point. Therefore, it is vital to place ample consideration into a sonar unit’s operating characteristics and capabilities to get the most bang for your buck.

Questions & Answers

What are the benefits of ice fishing fish finders?

The use of an ice fishing fish finder allows anglers to assess all that lies below a lake’s frozen surface. This is of significant value, as ice anglers are primarily unable to view typical signs of fish activity that take place close to the water’s surface. On unfrozen lakes, fish can often be seen striking at schools of baitfish, jumping above the water’s surface, and swimming in the shallows. However, ice anglers are never presented with this opportunity.

A fish finder provides ice fishers with intel that they would otherwise not receive, thereby allowing these anglers to make the best possible use of their time. These are also generally compact in design, making it quite easy for anglers to reestablish their efforts elsewhere, should success prove tricky to come by.

What’s the difference between an ice fish finder and a regular fish finder?

The vast majority of today’s ice fishing fish finders are of the flasher type. Flashers feature an illuminated wheel-style display that alerts to the presence of fish at a particular depth. This differs from the down/side imaging sonar units that are heavily employed on open water. Flashers are used for ice fishing, primarily because they do not require the use of solid-state transducers.

Alternatively, several anglers have begun using compact, portable fish finders, which utilize handheld displays. Some of these units also possess Bluetooth capabilities and can be paired to an angler’s cell phone.

Do I need a waterproof fish finder?

When selecting a fish finder for purchase, it is always a great idea to first consider the weather conditions you anticipate facing. While ice fishing fish finders do not necessarily need to be waterproof, they operate in extreme temperatures, often harsh on electronic devices.

When selecting a sonar unit for ice fishing use, it is essential to study a product’s operating temperature range carefully. An ice fish finder must be capable of withstanding temperatures as low as 0-degrees Fahrenheit.


The first step to ice fishing success is locating an excellent location to base your efforts. A fish finder simplifies this process by allowing anglers to take stock of all under the ice. Once fish are found in fair numbers, an angler can get down to the business of catching their limit.

However, not all ice fish finders are created equally. Some fish finders are much more portable than others and feature a far greater number of additional features. The information featured above will guide you in your efforts to locate the best possible sonar unit to fit your specific needs. With the purchase of a new fish finder and a little luck, you will be pulling fish from below the ice in short order.
