Humminbird HELIX 7 CHIRP MEGA SI GPS G4N Fish Finder - Professional Grade Marine Electronics

Experience unparalleled underwater clarity with the Humminbird HELIX 7 CHIRP MEGA SI GPS G4N fish finder, featuring revolutionary MEGA Imaging technology that delivers up to 3 times more detail than standard sonar. This professional-grade marine electronics unit combines advanced CHIRP sonar, precision GPS navigation, and comprehensive networking capabilities in a rugged, waterproof design built for serious anglers and marine professionals.

Revolutionary MEGA Imaging Technology

MEGA Side Imaging

Crystal-clear underwater views extending 125 feet on either side of your boat with unprecedented detail resolution. MEGA Side Imaging operates at 1075-1150 kHz frequencies, providing up to 3 times more detail than standard 455 kHz Side Imaging, allowing you to identify structure, fish, and bottom composition with remarkable clarity.

MEGA Down Imaging

Achieve exceptional underwater clarity straight down to 125 feet below your vessel. The advanced MEGA Down Imaging technology reveals fish-holding structure, vegetation, and bottom hardness with extraordinary detail, giving you the intelligence needed to make informed fishing decisions.

Dual Spectrum CHIRP Sonar

Advanced CHIRP technology covers multiple frequency ranges simultaneously (83/200 kHz with 75-155/130-250 kHz sweep), delivering highly detailed fish arches and superior target separation. Choose between Wide Mode for maximum coverage or Narrow Mode for focusing on precise details, with depth capability up to 1,200 feet using the included transducer.
