M3L Ice Fishing Sonar Flasher

The M3L is still built on the foundation of MarCum's very first sonar. A workhorse of the lineup, the M3L exhibits many of MarCum's patented features such as a moveable zoom anywhere in the water column - a key angler advantage that put Marcum on the map. MarCums for the past two decades have been sought after for moveable zoom alone, as it's this patented feature that forever changed the ice cape.
