The Beginner’s Guide to using an Ice Fishing Sonar

Every year, a new set of anglers both young and old learn to use ice fishing sonar or flashers for the first time.  That said, I encounter many anglers on the hardwater each year that still have their ice sonar depth finder on default factory settings from when they bought the unit 10 years ago.  Whether you’re brand new to the game, or it’s old-hat, here are some answers to age old questions along with new ones to keep it interesting and catch more fish.

It’s this time of year when our ice sonar is swapped for long rods and soft water, but that doesn’t mean your MarCum should be put in the back corner of the garage. All sonar systems, digital or mechanical styles, offer keys and cues that help anglers be more successful on the water

That’s especially true in small crafts like kayaks, canoes, or small skiffs where a larger, permanently mounted traditional LCD display isn’t in play. Here’s just a few ways to trick your craft, whatever it may be, and get the very most from your MarCum.

Finding More Fish With Your Hardwater Finder

Marking More Fish on Your Hardwater Finder

From the day you get your first flasher, the ice-fishing universe is forever changed. Ice anglers go from simply guessing at bites and what may or may not have been a fish, to tracking them throughout the water column. Not only can you use it to find fish and track how they respond to your bait, but you can also use it to find active fish before a line is even wetted.  At one time, it was considered somewhat odd; almost a novelty. Now, ice-fishing electronics are a multi-million dollar category, and the thought of fishing without one seems pointless.

The Best Ice Fishing Sonar for 2022


Since introducing cutting edge sonar technology to mechanical flashers nearly 20 years ago, MarCum has sought to build the best sonar on-ice, bar-none. Recent advances saw MarCum bringing the first digital sonar to the market, giving anglers a host of ample options when hitting the ice this winter. Read on to gain a better understanding of your options, and ultimately decide which is best for your style of fishing.

Midwest angler Joel Nelson knows a thing or two about ice sonar.  As MarCum’s longest tenured pro-staff member and media personality, he’s been running a MarCum since the brand’s inception.  Though he could run any fish finder on the planet, he’s an avid fan of the M1.  “It’s really a sonar that takes me back to some of the original MarCum units that just flat caught fish,” says Nelson.  “You get exactly what you need in an ice locator, ready to fish out of the box.”  Nelson logs thousands of miles across the ice belt each season, fishing and filming for a host of TV and video segments, all while toting an M1.  “I appreciate so many of the MarCum units in the lineup, but I’ll always have an M1,” says Nelson.

Tony Roach, a man who has seen just about everything that swims on a host of ice-fishing sonar units.  “That’s a walleye,” he confidently announced while staring at his MarCum M1.  “See it belly-to-bottom, then come up, then drop down.  It’s done it about three times in the past 30 seconds.”  Eventually, Tony connects, bringing a particularly goldeneye up on a panfish jig of all things.  How did he know it was a walleye, when we had landed nothing but gills the prior 10 hours on ice?  More importantly, what are the tell-tale signs, species by species, that will help us determine what we’re fishing for, and ultimately what bait to present and how?

Press Release – New Hope, MN (9/29/21) – Marcum Technologies, the undisputed leader in ice-fishing-specific sonar and cameras, takes tech to the next level. Their long-held principle is that features are useless unless they help an angler catch fish, and that can be seen throughout decades of innovation. Patented technology like moveable zoom that led to angler’s ability to target fish anywhere in the water column was the first ping heard round the world among the ice sonar community. They followed it up with additional advancements to help distinguish echoes from noise in an interference rejection system so advanced, it’s also patented.
