• CHIRP Digital Sonar: View details that other forms of sonar won't show you. Humminbird CHIRP Digital Sonar is engineered to help you see individual fish, clearly identify bait and structure, and reach greater depths and range.

• SwitchFire Sonar: Take command of how your sonar returns appear. With two display modes, you can add or remove detail, account for water depth, temperature and turbulence, even watch lure presentations - all at the push of a button.

• Dual Beam PLUS Sonar: Two beams combine for great detail and a generous coverage area, helping you identify fish, structure and contours. Use the narrow beam for high-accuracy returns of fish, structure, detail and the bottom profile. Opt for the wide beam when you want a larger search area. You can view the beams separately, side-by-side or blended together for the complete picture. Your coverage area will be equal to your depth.

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 Compatible: Upgrade to the unrivaled accuracy and detail of Humminbird LakeMaster maps. From easy-to-read contours, to highlighed depth ranges, to scrollable lake lists, you'll have all the tools you need to make every moment count.
