The first step in your pre-season routine should be checking your batteries. Most flasher failures on the ice are caused by a bad battery.

Leaves are gone from the trees, and that’s your green light to grab your MarCum flasher or digital system from the garage and get ready for the ice-fishing season.

The first step in your pre-season routine should be checking your batteries. Most flasher failures on the ice are caused by a bad battery, so now’s the time to inspect your MarCum’s power source. “You could be kicking yourself later if you don’t take a minute to check everything out now,” says ICE FORCE Pro-Staffer, Joel Nelson. “Nothing will wreck a good day of fishing faster than a bad battery, because there’s nothing you can do about it out on the ice.”

If you know you want to re-power your ice fishing fish finder or underwater fishing camera with Lithium, but you don’t know why, here’s a great article that discusses all the benefits that Lithium has. In general, 12v lithium batteries possess key advantages over SLA batteries, but it’s important to know a bit more about the details of each as your power source may be the most notable piece of ice fishing gear you purchase this season.

“Before underwater cameras, I used to think that certain weed-beds held bass, and others had the panfish I was after.  Careful study and lots of on-ice viewing showed that most often, the best weeds and weedbeds held both, but few panfish roam edges or openings in the presence of predators.  Two-feet can be too far if you’re trying to get a bull gill to come from cover and eat.  Punch a hole right on top of them, where they don’t have to leave the safety of cover, and you can pluck them from where you never thought they existed.”

No one can deny how much the sealed lead-acid (SLA) 12v battery has had an impact on ice fishing.  This battery has been the dominant player in the game and has been used extensively for decades in flashers, digital units and camera systems throughout the ice belt. 

about the details of each as your power source may be the most notable piece of ice fishing gear you purchase this season.  Whether looking to re-power, or upgrade your ice fishing fish finder to a better, longer-lasting, or lighter lithium battery, this article will lead you through the key components to making a good choice.

TONY ROACH AND JOEL NELSON TALK ABOUT THE PAST 20 YEARS AND EVERYTHING THEY HAVE LEARNED A ANGLERS THROUGH THE LENS OF AN UNDERWATER CAMERA.

One of the most common questions heard from new ice anglers relates to electronics – “Which is better – an underwater camera or a flasher/sonar?” The short answer is that it really depends.

The long answer is that there are certain situations that each unit type excels in. Depth, water clarity, habitat, and fishing style greatly impact which unit is right for a specific set of circumstances. In a perfect world, an ice angler should have both. This is particularly apparent for anglers that target panfish during the winter months.

Who doesn’t have boxes of jigs laying around?  No matter the species, it could be the most universal, widely copied, and versatile lure of all time.  If we’re talking live bait, it’s the best delivery method for meat that I know of.  If plastics, well there’s usually a jig involved here too. 

Starting with a standard jig-head, you have to think about what you’d like to do with it. If you’re threading on a fathead minnow, a will be the logical choice. The same can’t be said if you’re looking to fish plastics, as plastics fish best with an aggressive wire keeper.

As for other features and color, think about the water clarity you’ll be fishing in. Anything with a blade or propeller adds flash and vibration, which may be a necessary part of the presentation. Big minnows call for a , and suspended fish call for a that rises above a weight on the bottom. So many jigs, so many scenarios, but you need to match the style of jig to the type of fishing you’ll be doing.

New Hope, MN (10/25/2021) – Marcum Technologies, the undisputed leader in underwater viewing, takes an on-ice staple and improves it with lighter, longer-lasting lithium batteries.  A new generation of anglers takes for granted what cameras have brought to the sport.  Inline reels and the effect of lure-spin was revealed through watching fish swim away on an underwater camera.  Winter panfish location and the connection to green standing aquatic plants, along with countless other observations; all brought to you by underwater viewing, now made better with a little help from an advanced fuel source.

It could be the most common question found on internet forums, Facebook groups, and among the freshman class of ice’s newest anglers – “Sonar or camera?” Sounds like a simple question. Multiple choice even. The answer has always been straight-forward too, with most experienced anglers leaning towards a sonar first, then purchasing a camera to eventually fill in the knowledge gaps as needed depending upon their species of interest.

Tony Roach is no stranger to that game, as he fishes across northern Minnesota each winter, doing his best to put clients continuously on panfish, perch, and walleyes. It should come as no surprise then that underwater viewing systems are a key part of his strategy, and have been since their inception.

His camera and digital sonar approach mimics his now-famous “ice-trolling” concept of roaming select structural elements while drilling holes continuously, in an effort to both locate fish and stay on them. Few have drilled as many holes in the hardwater as Tony, and fewer yet have followed that up with as much underwater viewing as he has either.

The upshot is a 1-2 punch of underwater viewing and sonar that focuses on two main parts; the finding, and then catching, each of which utilizes different strong-suits of cameras and traditional sonar.

The standout feature of MarCum’s Lithium batteries is their lithium chemistry, which sets them apart from the competition. Not all lithium batteries are created equal, and MarCum’s line of Lithium batteries showcases a chemistry type, with its own unique advantages. Lithium Iron Phosphate (LiFePO4) is the ice anglers ideal chemistry, which strikes a balance between weight, cold weather performance, and charge cycle longevity.

It’s amazing how many anglers have an underwater ice fishing camera for winter use, and forget to pack it in the boat for fishing opener. In fact, open-water applications abound when it comes to everything from species identification, to finding green weeds, or simply identifying water clarity traits from one end of the lake to another.

The fact that now your underwater camera for fishing can be so much more mobile is a major benefit to its use, and the fish-finding information you unlock with it is rather limitless. Here’s just a few ways and reasons to get more use from your winter camera, come spring, summer and fall.

Underwater cameras are undoubtedly one of the greatest technological advancements in the sport of fishing these past few decades. Anglers in recent generations have come to depend on cameras to do far more than help them watch fish eat, but to observe their surroundings, study fish behavior and movements, even learn how fish certain baits better. Not only then has it been a technology that’s useful in its own right, but the simple fact is that underwater viewing has helped push forward the sport of fishing in general. From evolutions in tackle design, reels, and line, to changes in the way we fundamentally fish, looking at the underwater world through a camera is here to stay.

From the industry front-runner in ice electronics, comes a new leader in the batteries that power them. It’s only fitting that MarCum Technologies, in the quest to constantly improve their ice offerings, brings advancements not only in sonar or cameras, but the very power-plants that fuel them.
