Humminbird HELIX 7 CHIRP SI GPS G4 Fish Finder/Chartplotter

The Humminbird HELIX 7 CHIRP SI GPS G4 Fish Finder/Chartplotter combines detailed side and down imaging, accurate GPS navigation, and powerful 2D sonar in a straightforward standalone system. Its bright 7-inch color display offers a 1024 × 600 resolution and multiple split-screen views for monitoring sonar and navigation data simultaneously.

The included XNT 9 HW SI T transom-mount transducer provides CHIRP Side Imaging, CHIRP Down Imaging, and Dual Spectrum CHIRP sonar. Side Imaging scans up to 400 feet on each side at 455 kHz, while Down Imaging delivers detailed coverage to 400 feet. Dual Spectrum CHIRP produces defined fish arches, clear bottom returns, and 2.5-inch target separation.

Internal GPS and Humminbird Basemap help anglers navigate more than 10,000 lakes and coastal waters within the continental United States. AutoChart Live creates personalized maps displaying depth contours, vegetation, and bottom hardness, with eight hours of internal recording.

Compatible with optional LakeMaster, CoastMaster, and selected Navionics charts, the HELIX 7 SI GPS G4 is an excellent standalone fish finder and chartplotter for anglers who need dependable Side Imaging without advanced Ethernet networking.
