Humminbird Helix 7 Chirp MSI GPS G4N Features

Dual Spectrum CHIRP

Dual Spectrum CHIRP is a sonar technology that uses a wide range of frequencies to provide a clearer, more detailed image of the underwater environment. It is capable of detecting fish, structure, and bottom contours with greater accuracy than traditional sonar.

MEGA Down Imaging

MEGA Down Imaging is a high-resolution sonar technology that uses multiple frequencies to create a detailed image of the underwater environment. It is capable of detecting fish, structure, and bottom contours with greater accuracy and clarity than traditional sonar.

MEGA Side Imaging

MEGA Side Imaging is a sonar technology that uses multiple frequencies to create a detailed image of the underwater environment in a wide, side-to-side view. It is capable of detecting fish, structure, and bottom contours with greater accuracy and clarity than traditional sonar.
