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.
