Humminbird Helix 7 G4N GPS Fishfinders – Fish finders

• Revamped with new age technology, they have managed to bring both Mega Down Imaging and Mega Side Imaging Sonar to this 7 inch model. Available in three models to offer varying levels of detail and accuracy, they will certainly prove their worth whilst out on the seas!
• Dual Spectrum CHIRP Sonar: Before you cast, know what’s down there thanks to long, well-defined fish arches, and a clear view of fish-holding structure and the bottom. Powered by our proprietary, Low Q CHIRP transducer, Dual Spectrum offers two ways to search: wide mode for maximum coverage and narrow mode for maximum detail.
• Basemap Built-in: Their enhanced standard basemap provides you with a clear view of underwater terrain and surrounding points of interest so you can fish and navigate with total confidence. Identify buoys, day markers, hazards, marinas, contours, depth markers and much, much more. Includes charts of more than 10,000 lakes, plus coastal coverage for the U.S.
• AutoChart Live: Create real-time maps of your fishing spots, with access to patented Lake Master® features. Map depth contours, bottom hardness and vegetation as you drive your boat, with eight hours of built-in recording time.
• Ethernet Networking: High-speed Ethernet allows you to build a powerful, professional-grade fishing system. Easily connect multiple fish finders, or upgrade to add-on technologies like Minn Kota i-Pilot Link, 360 Imaging and CHIRP Radar.
• Bluetooth: Enable features like wireless software updates from the FishSmart App and also keep your phone out of the water and in your pocket by displaying notifications on your fishfinder. Additionally, you can take control of your most-used features with an optional Bluetooth remote (RC2).
• MEGA Down Imaging: Get unprecedented underwater clarity with coverage down to 125 feet below your boat. You’ll unlock new details with up to 3X more output than standard Down Imaging sonar.
• MEGA Side Imaging: See the world below like never before with crystal-clear viewing out to 125 feet on either side of your boat. You’ll unlock new details with up to 3X more output than standard Side Imaging sonar.
• SI: Side Imaging
• DI: Down Imaging
