The MarCum Sonar Combination Unit with Lithium Shuttle brings the best of both worlds: pinpoint positional accuracy and long-heralded MarCum sonar, giving you double the ice-fishing advantages. Dual-beam precision digital sonar offers best-in-class widest and narrowest viewing angles on the market. A 20° ultra-wide-angle sonar cone sees fish further to the sides, giving you an advantage for finding and catching. An 8° narrow-beam transducer targets only the fish directly beneath you at the push of a button, and overcomes standard sonar issues on steep breaks.
The patented, 12-setting interference rejection lets you tune out noise better than ordinary sonar systems, with fine-tuning controls of gain modes, ping speed, and cone angle. The internal GPS receiver takes you to the spot and brings you back time after time. Built-in Navionics® Basemap provides more lakes and better coverage from a host of sources. A microSD card slot allows custom, optional mapping upgrades. The True-Time 7″ LCD works in tandem with sonar to offer all screens in true Realtime-display with zero latency and no lag.
