HELIX 7 CHIRP MSI GPS G4N

The HELIX 7 CHIRP MEGA SI GPS G4 features advanced technologies: MEGA Side Imaging and MEGA Down Imaging, Dual Spectrum CHIRP Sonar, AutoChart Live, and built-in GPS. The updated high-resolution 7" diagonal screen displays high-quality information.

Keypad control: operate the Helix fishfinder easily and comfortably with soft-touch buttons that work reliably in any conditions. Use preset screen combinations by selecting from the user-friendly menu

MEGA Side Imaging: See the underwater world more clearly than ever before, up to 38 meters to each side. With this sonar, image detail is up to three times better than with standard SI sonar.
MEGA Down Imaging: Unmatched clarity up to 38 meters below your boat, with image detail up to three times better than standard DI sonar.
Dual Spectrum CHIRP: Before you even cast your bait, check out the bottom structure, bottom relief, and highly detailed fish arches. Using our proprietary Low-Q CHIRP sonar, Dual Spectrum allows you to scan in two modes: Wide Mode—which covers the bottom as broadly as possible—and Narrow Mode—which highlights and displays the finest details.

AutoChart Live: Create your own maps in real time. While on the water, you can generate a bathymetric map, along with information on bottom hardness and vegetation. Up to 8 hours of data can be recorded and saved to an AutoChart Zero Line SD card. This allows you to create maps of unlimited size for your favorite fishing spots.

Built-in GPS

Included: display, sonar, mounting hardware, power cable, and mounting bracket. 2-year warranty.
