The dog days of summer and that’s your green light to grab your MarCum flasher or digital system from the garage and give it a once over and top off the battery.

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 MarCum 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.”

Though there is a slightly higher cost of entry to MarCum for putting these batteries in as standard options, the benefits of Lithium battery technology are many. For most anglers, the weight savings alone are enough to switch out their old Sealed Lead Acid (SLA) batteries, with new Lithium versions weighing less than half of their predecessors. You’ve also got longer run-times, even from batteries with similar amperage output that are not Lithium. That means you can fish for durations numbering days, not hours, with anglers often only re-charging their batteries after a long weekend of use.

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.

If you’ve tried to make a major purchase in 2021, you’ve been affected by the global supply chain slowdown.  Materials are backordered, shipping is slow, containers held up; there are seemingly more reasons than ever these days for why you can’t get at what you’re looking to own. 

Press Release – New Hope, MN (10/22/20) – Two decades ago, MarCum released its first underwater viewing system, giving eyes below the surface to an entire generation of anglers.  Their world has been forever changed because of it, from the way modern ice anglers’ fish to the equipment they use, underwater viewing has shaped the evolution of the sport.  While the systems themselves have also evolved through the years, the one thing that remains consistent over time is the amount of information anglers glean when seeing underwater for the first time. 

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. 

New Hope, MN (11/18/21) –Based on the growing demand for MarCum products in Eastern Canada, the Minneapolis manufacturer has engaged Raytech Electronics, a warranty and maintenance service center to enable owners to receive service without having to hassle with international shipments. Raytech will be handling warranty and non-warranty repairs for MarCum consumers starting November 17th, 2021. This new relationship is expected to decrease repair service times by at least 5 business days for Eastern Canadian customers.

LiFePO4, Li-ion, & Lead-acid Batteries have slightly different long-term storage requirements. Find the best way prolong your battery life.

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.

Two decades ago, MarCum released its first underwater video camera with a monitor for fishing, giving eyes below the surface to an entire generation of anglers.  Their world has been forever changed because of it, from the way modern ice anglers fish to the equipment they use, underwater viewing has shaped the evolution of the sport.  While the systems themselves have also evolved through the years, the one thing that remains consistent over time is the amount of information anglers glean when seeing underwater for the first time. These MarCum underwater cameras can be used for ice fishing, freshwater, and saltwater fishing.

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.

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.
