MarCum MX-7GPSLi Lithium Combo GPS/Sonar System | High-Definition Ice Fishing Fish Finder | Advanced Sonar with Lithium Battery | Premium Fishing Gear

Real-Time 7” LCD Display – Our sonar and display work in tandem to offer ALL screens in true real-time display with zero latency, and no lag. Our response times and refresh rates are the fastest in the industry, a requirement for lightning-quick fish that can spit a hook as fast as they can eat one. That speed is offered in brightness levels currently unmatched, with luminance up to 1,000 nits (cd/m2), a measure rarely found on any 7” screen.

Dual beam Precision Digital Sonar Engine – A 20 degree ultra-wide angle sonar cone sees fish further to the sides, giving you an advantage for both finding AND catching. An 8 degree Narrow Beam Transducer (NBT) targets only the fish directly beneath you at the push of a button, and overcomes standard sonar issues on steep breaks. We live by the accuracy of our sonar, and are proud of the industry-leading ½” target separation we offer.

Internal GPS Receiver – Featuring the latest spec for highly precise positional accuracy, we take you to the spot and bring you back time after time, with smoother tracking and exacting detail. Navionics Basemap Onboard – More lakes and better coverage come from a host of sources. Through proprietary mapping and public data, we strive to never leave you blind.

Patented Interference Rejection – 12 settings so dialed-in, they’re protected via U.S. patent, doubling the ability to tune out noise when compared to other sonar system. Further and finer control of your display is also offered through additional gain modes, ping speed, and cone angle, making Marcum the choice for visible clarity and acuity. Patented Moveable Zoom – Zoom anywhere in the water column to target bottom dwelling fish, as well as suspended species with ease

Advanced Lithium Battery Power – Every MX-7GPS comes standard with a 12V11amp/h Lithium-ION battery, the new standard in lightweight, fast-charging, and long-lasting fuel for your ice electronics. Run your screen as bright as you’d like, and fish for days without recharging. Our sonar comes with a power source worthy of technology that would require it.
