Choosing an Ice Fishing Fish Finder

Ice Fishing Flashers—Simple & Reliable

Ice fishing flashers are the traditional choice for ice anglers, trusted for decades for their speed and accuracy. Like all fish finders, flashers use sonar technology: a transducer sends sound waves beneath the ice, then measures the return signal to detect depth, bottom structure, and fish. The display is a circular dial, showing the entire water column. Different color signals—red, yellow, and green—represent the strength of the return.

Flashers are simple, reliable, and great for anglers who want feedback without extra features like GPS or mapping.  They are also known to be relatively inexpensive, making them great options for anglers who value a finder without sacrificing their budget.

Convertible Units—Year-Round Versatility

If you want a fishing electronic setup that works on the ice and in open water, a convertible unit is your best option. These systems use the same fish finder you’d mount on your boat in summer, paired with an ice fishing conversion kit that includes an ice transducer, power source, bag, and cradle.

Because it features many distinct technologies like GPS and mapping, convertible units are known to be more expensive than basic flashers. Most convertible units feature a flasher view as well as a typical standard sonar view as well/

SCHEELS Expert Tip: Our Experts strongly recommend checking the compatibility between your unit and the conversion kit before purchasing either.

Live Sonar Technology—Real-Time Underwater View

Live sonar is the latest innovation in ice fishing electronics, giving anglers a real-time view of fish movement and structure beneath the ice. Unlike traditional sonar or flashers that show history or return signals, live sonar provides instant video-like feedback, so you can see how fish react to your lure in real time. These systems also often combine sonar and radar-based imaging to deliver multiple viewing modes.

Because of their updated technology, they’re known as the most expensive piece of ice fishing technology, with a steep learning curve for beginner anglers. However, these finders are known to provide incredible accuracy and detail without drilling multiple holes.

Underwater Cameras—Visual Confirmation

An underwater camera is not a replacement for a sonar fish finder, but it’s a valuable tool to use alongside your flasher or live sonar. Cameras give you an actual video feed of what’s happening under the ice in real time, allowing you to identify fish species, observe fish behavior, and check the type of vegetation or structure. These cameras do, however, require extra battery power and cable management, and can have limited visibility at night.
