Humminbird Helix 7 Chirp MSI GPS G3N Features

Dual Spectrum CHIRP

Dual Spectrum CHIRP is a sonar technology that uses two frequencies to create a detailed image of the underwater environment. It is capable of providing greater clarity and detail than traditional sonar systems.

MEGA Down Imaging

MEGA Down Imaging is a sonar technology that uses high-frequency signals to create a detailed image of the bottom of the water. It is capable of providing a much clearer and more detailed image than traditional sonar systems.

MEGA Side Imaging

MEGA Side Imaging is a sonar technology that uses high-frequency signals to create a detailed image of the sides of the water. It is capable of providing a much clearer and more detailed image than traditional sonar systems.
