The Humminbird HELIX 7 CHIRP MEGA SI GPS G4N Fish Finder, for the price of a state-of-the-art pair of fishing waders, provides you with fingertip command of your boat with navigation, fish-finding tools and images, and Bluetooth communication – all accessed through a high-definition seven-inch display. The HELIX 7 CHIRP MEGA SI G4N supplies advanced and enhanced views of fish below deck through both MEGA Side and Down Imaging (three times the output of standard Side and Down Imaging). Dual-Spectrum CHIRP (Compressed High-Intensity Radar Pulse) Sonar and preloaded split-screen options mean you'll never miss a fish. All HELIX 7 GPS G4N models support Ethernet networking, Bluetooth, NMEA 2000, Wi-Fi, and are compatible with the One-Boat Network that allows Humminbird, Minn Kota, and Cannon products to integrate and communicate seamlessly (compatible products sold separately). The internal GPS guides you through underwater terrain and above-water structures, while the included Humminbird Basemap of more than 10,000 lakes and the continental U.S. coastline helps chart your course. AutoChart Live allows you to create real-time maps to and from favorite and newly found fishing spots. A pair of fishing waders can't do any of these for you. Yet, you will have the power to do these and more in your fishing boat with the mastery of a Humminbird HELIX 7 CHIRP MEGA SI GPS G4N Fish Finder!
