From the ice age to the digital age, MarCum’s vanguard LX-7L Lithium LiFePO4 has forever transformed the game of hunting fish on frozen water. Over a decade of cutting-edge sonar design in the making, the radically innovative LX-7L Lithium LiFePO4 has been built with the optimum blend of sonar DNA from MarCum LX Flasher and Digital Fish Finding technologies. A true breakthrough in “big picture” ice sonar, LX-7L Lithium LiFePO4 presents anglers with an incredible interactive ice fishing experience in a panoramic 8-inch LCD environment (four vividly rich color palettes included.) Multiple industry-exclusive features provide a dazzling array of precious fish-finding Intel. Fully user-defined on-screen “Dashboard” displays digital depth, battery voltage, range, gain, interference rejection (IR), target adjust, or any combination thereof. LX-7L Lithium LiFePO4 “Multifaceted Sonar Display” also gives anglers fully customize window views, including water-column vertical, vertical zoom, flasher-dial and traditional horizontal LCD graph displays. Sonar Footprint technology displays scan area at any depth, with either 8 degree or 20-degree transducer cone angles. This provides a keen awareness of fish targets relative to the transducer, and your lure; also helps prevent adjacent (non-MarCum) sonar users from picking up interfering LX-7L Lithium LiFePO4 pulses by avoiding the “footprint” area. All LX-7L Lithium LiFePO4’s come preloaded with the full menu of MarCum’s patented features, as well as a USB port for firmware upgrades.
