  • Technologies:
    • MEGA Down Imaging
      • With up to three times the output of standard Down Imaging, Mega Imaging uses a high-frequency sonar to easily distinguish fish from structure, see the direction fish are facing, and target individual species. Down Imaging+ gives you crystal clear picture with coverage down to 125 ft. below your boat.
    • CHIRP Digital Sonar
      • CHIRP stands for "Compressed High-Intensity Radar Pulse." By covering a wide range of frequencies, CHIRP produces more accurate, more detailed returns of fish, structure, and the bottom.
    • Dual Spectrum CHIRP
      • 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 Humminbird's proprietary Low Q CHIRP transducer, Dual Spectrum offers two ways to search: wide mode for maximum coverage and narrow mode for maximum detail.
    • MEGA 360 Imaging
      • MEGA 360 Imaging sweeps up to 125 ft. in every direction around your boat to deliver the clearest images of structure, the bottom, and fish, even while you're sitting still.
    • Precision GPS
      • Precision GPS provides an accurate position fix, meaning more accurate waypoints and boat positioning for better fishing.
    • Humminbird Basemap
      • Humminbird's 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, daymarkers, 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 Humminbird LakeMaster features. Map depth contours, bottom hardness, and vegetation as you drive your boat, with eight hours of built-in recording time.
    • LakeMaster and LakeMaster Plus Compatible
      • Upgrade to the unrivaled accuracy and detail of Humminbird LakeMaster maps. From easy-to-read contours to highlighted depth ranges to scrollable lake lists, you'll have all the tools you need to make every moment count. Maps are sold separately.
    • SmartStrike
      • SmartStrike cards combine High-Definition LakeMaster lake map data and extensive search algorithms to help you pattern and locate fish at any time of the year.
    • CoastMaster
      • CoastMaster maps deliver unrivaled nearshore and offshore fishing performance.
    • Ethernet Networking
      • High-speed Ethernet allows you to build a powerful, professional-grade fishing system. Easily connect multiple fish finders or upgrade with add-on technologies like Minn Kota i-Pilot Link, Minn Kota Talon, 360 Imaging, and CHIRP Radar.
    • i-Pilot
      • i-Pilot Link enables your Humminbird fish finder and Minn Kota trolling motor to communicate, delivering precise, automatic boat control.
    • NMEA 2000
      • From boat performance to weather and water conditions, make sense of it all with Humminbird NMEA 2000 Networking. Easily connect sensor after sensor to your vessel's Humminbird system. Bearing, depth, engine status, tank level, electrical – you name it, we can display it. Conserve valuable fuel, make informed decisions, and see red flags with an at-a-glance view of all relevant information.
    • AIS
      • Track other vessels with Humminbird's state-of-the-art AIS technology. It takes the risk and guesswork out of navigating high-traffic channels or low-visibility seas.
    • Humminbird AutoPilot
      • Set your heading or turn pattern and maintain your desired route regardless of speed or sea and wind conditions.
    • Bluetooth Networking
      • Keep your phone out of the water and in your pocket by displaying notifications on your Humminbird. You can also take control of your most-used features with an optional Bluetooth remote (RC2).
    • One-Boat Networking
      • Many Humminbird models seamlessly integrate and communicate with Minn Kota and Cannon products to unlock more features and capabilities for anglers everywhere. Make the most of your time on the water with the exclusive boat control and fish-catching features of the One-Boat Network.
