M Series Press Release


Cutting-edge M3 and M5 Models Enhance Angler Advantage and Catch Success

New Hope, Minnesota (September 5th, 2023) – MarCum Technologies, a leader in innovative fishing electronics, is proud to unveil its highly anticipated expanded lineup of Sonar Flasher Ice Fishing Systems for the upcoming 2023 ice fishing season. Building on its legacy of groundbreaking technology, MarCum introduces two new models, built on the foundation of proven performance of the  M3 and M5, designed to provide anglers with unparalleled sonar performance and the ultimate edge on the ice.

M3: Where Innovation Meets Tradition

The MarCum M3 stands as a testament to the company’s commitment to pioneering excellence. As the cornerstone of the lineup, the M3 proudly carries forward MarCum’s foundational sonar technology while incorporating groundbreaking enhancements. Patented features, such as moveable zoom anywhere in the water column, remain a core advantage that has defined MarCum’s reputation over the past two decades. The M3’s ability to navigate through zoom at various water depths enables superior angling for a wide range of species, from bottom-dwelling walleye to suspended bluegill, crappie, and lake trout.

One of MarCum’s most acclaimed innovations, the noise-cancelling interference rejection system, continues to set the standard for clutter-free displays, even in environments with multiple units in close proximity. The M3’s 200kHz band, along with other frequency options, ensures compatibility across different ice fishing scenarios.

Boasting an impressive 2,000 watts of peak-to-peak power, the M3’s whisper-quiet brushless motor complements the advanced MBC TrueColor targets, offering unparalleled brightness and clarity. The unit’s ultra-wide 20-degree coverage, facilitated by the industry’s widest single-beam transducer, provides anglers with an expansive view of sub-surface activity. High-definition standard and patented zoom modes offer target separation as precise as 1″, giving anglers a distinct advantage in distinguishing fish from jigs, schooling fish from individual targets, and fish from bottom structures.

For budget-conscious anglers seeking excellence, the M3 lineup now includes the M3X model, offering flexibility in selecting the optimal power source. Additionally, the M3LR model comes complete with a lightweight, long-lasting lithium Brute battery, packaged within the meticulously designed Roamer soft-pack, tailored to complement anglers’ movements on the ice.

M5: Elevating Precision and Performance

The MarCum M5 takes sonar performance to new heights, delivering a 3-color, real-time flasher that reflects the brand’s unyielding commitment to scientific advancement. Drawing from MarCum’s legacy of excellence, the M5 introduces enhancements that have stood the test of time.

The M5’s signal strength and 3/4″ target separation empower anglers with the clarity needed to distinguish between fish and the bottom, or to pinpoint the largest fish within a school. The dual-beam transducer, a unique feature of the M5, offers on-the-fly sonar cone angle adjustment, enabling anglers to focus on fish within striking distance.

MarCum-exclusive SuperFineLine (SFL) technology enhances the M5’s high-definition flasher mode, elevating standard definition to an impressive 3/4″ target separation for the entire water column. Max Brightness and Clarity (MBC) lighting ensures vivid sonar targets, smoothly displayed on the unit’s durable, brushless platform.

The M5’s patented zoom technology, operable across the water column, provides a distinct advantage when targeting suspended fish, a capability unique to MarCum systems. The unit’s remarkable interference rejection system is patented and features 12 steps, ensuring compatibility with various frequency sonars and minimizing cross-talk even in crowded ice fishing scenarios.

For anglers seeking premium performance, the M5 lineup includes the M5X model, catering to budget preferences while allowing the angler to choose the correct power source for the way they fish. The M5LR model sets a new standard for excellence, combining lithium-fueled power with the convenience of the Roamer soft pack, setting the bar for premium sonar flashers.
