The most advanced flasher-sonars ever built, the MarCum® “M” Series offers brushless, dead-quiet operation with dazzling bright and crisp color definition of bottom, fish, baitfish and your lure, all illuminated on the highest resolution display available in a commercial grade flasher. Acute .75-inch target separation distinctly identifies each individual object on the screen, so you can clearly discern the minuscule separation of a bluegill about to kiss your ice jig.

The difference between a good angler and a great one is their attention to detail. The M5L provides that element in a 3-color, real-time flasher that’s as scientifically advanced today as it was when released nearly two decades ago. Feature specs are useless unless they help you catch fish, which is why the M5L’s strength of signal with target separation down to 3/4″ is more than just a bullet point on a product box. That kind of sonar clarity allows you to differentiate fish from the bottom, or schooling fish from each other, to specifically target the largest fish in the group and catch them. With our dual-beam transducer, at the push of a button, an angler can quickly narrow the sonar cone angle and focus on fish within any striking distance of the bait. SuperFineLine (SFL) is another Marcum-exclusive, and it’s like having a High Definition mode for your flasher, all while improving standard definition from 1-1/2″ to 3/4″ for the entire water column. Max Brightness and Clarity (MBC) lighting ensures that sonar targets are as bright as they are sharp, digitally transposed on a super-smooth and quiet brushless platform that’s provided years of maintenance-free service. The M5L’s patented zoom technology is moveable anywhere in the water column, giving you the freedom and precision not only for bottom hugging species, but an exclusive advantage only MarCums can boast as it relates to suspended fish. This is true in shallow water ponds, as well as the deepest and clearest lakes down to 160 feet. Our industry-leading 12-step interference rejection system is so advanced, it’s also patented. That makes it compatible with any 200khz frequency sonar, along with other frequencies as well. The M5L’s sonar system pumps out 2,500 watts of expertly managed power, and is now fueled by a lightweight, long-lasting LiFePO4 lithium battery. This shaves a significant amount of the weight from the entire system, ensuring both angler AND flasher never run out of juice. Lithium technology is easy on the pocketbook too, offering lower cost of ownership by extending the life and use of any Marcum for thousands of charge cycles. Like all MarCums, the M5L is sold complete, including a deluxe-padded soft pack that provides years of protection in transit and use. No species of fish can elude the features and performance of the M5L, making it the most universally equipped multi-species flasher on the market.
