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.

It has never been used. it just sat in the box.
