Product Overview

Helix 8 Chirp Mega SI GPS G3N features an 8" display, Mega Down Imaging and Dual Spectrum Chirp Sonar. 

NEW to HELIX 7- MEGA Down Imaging
Get unprecedented underwater clarity with coverage down to 200 feet below your boat. You'll unlock more fish and structure with 20% more detail than MEGA Down Imaging Sonar.

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.

Humminbird Basemap Built-in
Our 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 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 highlighted depth ranges, to scrollable lake lists, you'll have all the tools you need to make every moment count.
