Humminbird Helix 7 Chirp SI GPS G4 Features

Dual Spectrum CHIRP

Dual Spectrum CHIRP is a sonar technology that combines the benefits of both traditional CHIRP and wide-spectrum CHIRP. It provides greater target separation and more accurate bottom tracking compared to traditional CHIRP, as well as improved resolution and detail compared to wide-spectrum CHIRP.

CHIRP Down Imaging

CHIRP Down Imaging is a sonar technology that uses high-frequency sound waves to create a detailed image of the bottom of the water. It provides a clearer image of the bottom structure and fish targets than traditional sonar, allowing anglers to identify fish and structure more easily.

CHIRP Side Imaging

CHIRP Side Imaging is a sonar technology that uses high-frequency sound waves to create a detailed image of the sides of the water. It provides a better view of the structure and fish targets than traditional sonar, allowing anglers to identify fish and structure more easily.

Humminbird Helix 7 Chirp SI GPS G4 Compatibility

Humminbird Helix 7 Chirp SI GPS G4 is compatible with:

  • AIS
  • AutoPilot
  • Minn Kota US2 Sonar

AIS

AIS is a system that allows vessels to identify and track each other for collision avoidance and maritime safety.

AutoPilot

AutoPilot is a system that allows a vessel to be steered automatically, based on pre-programmed waypoints or navigation data.

Minn Kota US2 Sonar

Minn Kota US2 Sonar is an advanced sonar system that uses sound waves to detect and map the underwater environment.
