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 our proprietary, Low Q CHIRP transducer, Dual Spectrum offers two ways to search: wide mode for maximum coverage and narrow mode for maximum detail.

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.

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.
