For nearly half the year, ice fishing in the north country is a simple fact of life—like taxes, death, and mischief—except immeasurably more enjoyable once you work through the “mischief” of staying warm. At least part of the fun part lies in the search for fish beneath the crystalline veneer—and thanks to the constant evolution of ice fishing fish finders, it’s never been easier. As an avid ice angler, I’ve been able to test out the best ice fishing fish finders and share my experience with them to help you find the best one for you. Here are my top picks. 

History of Ice Sonar

Close to forty years ago, a legendary angler named Dave Genz—aka Mr. Ice Fishing— engineered an ingenious way to garage-rig his flasher-sonar unit for ice duty. He called it the “blue box,” a portable, carriable sonar shuttle complete with a motorcycle battery for sonar power and an adjustable transducer arm that hung down in the water. Genz glued a small, round RV style level to the top of the ‘ducer to assure a clear, level signal and the clearest possible picture of fish and his lure. Attach an old Humminbird Super-Sixty or an early Vexilar FL-8 to the base in those days, and you were lightyears ahead of the crowd. 

I remember those early pioneering days with affection, occasionally fishing with Mr. Ice Fishing himself. Genz’s singular innovation forever transformed the game of ice fishing, opening the underwater world to our eyes and turning the sport into a dynamic and interactive pursuit. The first time I watched a “blip” of a fish ascend on the screen and stalk my jig, I was hooked for life. When underwater cameras arrived on the scene a few years later, our under-ice education soared to even greater heights. Today, given new innovations in live sonar, GPS, and underwater video, the best ice fishing fish finders are teaching us more about fish behavior than ever while even helping us better understand the value of catch and release.

Key Features

  • 9-inch ECHOMAP UHD 93sv chartplotter display
  • Panoptix LiveScope System
  • Panoptix ice fishing bracket with swivel pole mount
  • Portable ice fishing carry bag with sonar shuttle
  • Lithium-ion battery with battery charger

Why It Made the Cut

The ability to scout for fish and structure under the ice up to 200 feet in any direction without drilling additional holes is a major advantage, and it’s totally transformed the hardwater game. To make the best even better, Garmin has improved upon its previous LiveScope Ice Bundle by offering a lighter, longer-running lithium-ion battery and a more manageable cable system.

Pros

  • Intuitive live sonar display vividly depicts fish moving and reacting to your lure in near real-time
  • Adjustable transducer can look off to the sides (for finding moving fish) or straight down to allow the angler to watch fish react to a lure in near real-time
  • 12-volt lithium-ion battery lasts a long time in cold weather 
  • Includes traditional 2D sonar as well as LiveScope mode
  • Display unit comes preloaded with LakeVü g3 maps with integrated Navionics data covering more than 18,000 lakes in the U.S.

Cons

  • “Black box” sonar module and transducer arm make the unit heavy and harder to carry from ice hole to ice hole, relative to traditional ice sonar units

Product Description

After using Garmin’s Panoptix LiveScope technology for several winters, particularly for locating crappies and other offshore schooling species, I can’t imagine fishing without it. The fact that I can drill one hole, dip the transducer and rotate it 360-degrees and look at least 100 feet in all directions saves immeasurable amounts of time and drilling effort. It’s no longer a question of if you’ll find fish, but when. Not only does the technology allow you to discover hidden schools of fish—or individual large specimens—it also shows you to see the direction of travel and the number of fish in the school. Moreover, we can now discern different fish species, such as crappies versus perch.

One caveat: the potency of the technology, more than ever, highlights the need to release the larger fish of all species, as well as leaving fish alone when they’re in deeper water and vulnerable to the ill-effects of barotrauma.

How to Choose an Ice Fishing Fish Finder

Best Ice Fishing Fish Finders of 2022
Modern ice fishing fish finders make it possible to target trophy fish. Bill Lindner

When shopping for a fish finder, your primary considerations should obviously include your budget and your comfort level with various technology and extra features. If you simply want to see fish and your lure and aren’t interested in digital mapping, you’ll likely enjoy the simple functionality of an analog-style flasher. Also consider whether you’re a mobile angler like myself, fishing out on the open ice, or if you prefer to fish in the comforts of an ice fishing shelter. An underwater camera might be the most exciting (and educational) option if you prefer the latter. Also, regardless of technology, consider upgrading to one of the newer, lighter lithium-ion batteries. Although more expensive than standard gel cell batteries, lithium-ions offer longer runtime per charge and better cold-weather performance.

FAQs

Q: What’s the difference between ice fishing and traditional boat-mounted fish finders?

Generally, because you’re physically carrying your ice fishing fish finder from hole to hole, these units must be highly portable, housing LCD, transducer, and a small battery in one. Most of the top ice fish finder companies offer handy carrying cases or “sonar shuttles.” Most of these units can also be adapted for summer use, with the addition of optional power cables and transom-mount transducers. Ice fishing fish finders also excel for use in smaller rental boats, kayaks, etc., adding value to your purchase.

Q: Does an ice fish finder need to be waterproof?

Like your boat-mounted sonar, most ice units are fully sealed and largely water resistant. Ice fishing in rain isn’t a common occurrence, though all major sonar manufacturers build their units to withstand heavy snow or snowmelt that often accumulates. So long as you don’t submerge your display unit, waterproofness shouldn’t be an issue. Meanwhile, consider adding some sort of screen protector, particularly with flatscreen LCD models, to safeguard it during transport in pickup truck beds, pull-behind sleds, etc. 

Q: What’s the difference between a flasher and a digital sonar unit? 

The first difference between analog flashers and digital sonar units is that flashers present the water column in a circular dial configuration, with depths arranged like a clock. Generally, flashers operate and display fish and lure movements in near real-time, while digital sonar may present a barely perceptible lag. Analog flashers, however, don’t allow for split-screen sonar/map viewing and can’t offer quite the precision of digital technology, relative to target separation. Analog flashers are also perceived to be slightly more reliable, especially in sub-zero temperatures. That said, modern digital sonar units have become increasingly dependable, employing special heated LCDs to keep the liquid crystals functioning in all conditions.

Final Thoughts

Many anglers ponder which to buy first: an ice flasher/sonar versus an underwater camera. Both are considered invaluable hardwater fish-finding tools. For simply seeing fish and watching them interact with your lure, sonar remains the primary choice. And yet, for scouting new water—particularly shallow structure and vegetation where sonar views may be obscured—an underwater camera is invaluable, both as a fish-finder and as a learning tool. Eventually, most seasoned ice anglers add both tools to their arsenal. 

Finally, consider the rise of live sonar, such as Garmin Panoptix. This powerful tool gives anglers the ability to read below the ice without requiring additional holes or running the risk of spooking fish. Live sonar will eventually become standard ice fishing equipment among most serious hardwater explorers.
