About MarCum

What started out as a vision by two military engineers has blossomed into the leading underwater viewing systems and ice fishing sonar in the world. That said, it didn’t happen overnight, nor did it happen by accident.  Here’s our story, detailing where we’ve been, and where we’re going.

It doesn’t stop there, though. Everything we manufacture has been put through its paces on the water. The next time you see a MarCum product, think of our field testers that brave the cold, making notes with frozen fingers, tweaking and fine-tuning everything until it’s just right.  All while catching plenty of fish in the process.

Past, Present, and Future

MarCum has always been about building a better fish-trap, and that idea was born from two passionate anglers who just so happened to work on sonar in nuclear submarines for the US Navy. In the early 2000’s, they took the development of their already successful commercial ice units, on to another level.  Transferring this technical knowledge into real-world advantages for ice anglers, they created the LX-1, LX-3, and LX-5 sonar packages.  It started a revolution in ice electronics, driven by customer demands for hardware that was more crisp, precise, and feature-laden.
