Specifications
| Price (US) | Not published Humminbird's own product page for this exact unit states it is discontinued and shows no price; no US MSRP appears anywhere on humminbird.johnsonoutdoors.com for any HELIX SKU checked (Humminbird uses dealer/MAP pricing, not a published storefront price). The seeded name 'HELIX 9 CHIRP MEGA SI' is missing the '+' and 'G4N' that Humminbird's own site uses for the exact model; corrected here to match the manufacturer's naming, though this generation is no longer an active catalog item (the current 9" HELIX offering is sold only bundled, as the 'ICE HELIX 9 MSI+ GPS G4N MEGA 360 Bundle'). |

Humminbird's own product page for this SKU (accessed by guessing the URL slug after the model did not appear in the current 'shop/fish-finders/helix' catalog listing of 14 active results, which shows only 5"/7" units plus an 'ICE HELIX 9 MSI+ GPS G4N MEGA 360 Bundle') confirms the exact model 'HELIX 9 CHIRP MEGA SI+ GPS G4N' and states it is discontinued with no price shown. Its spec sheet gives, verbatim: 9" color TFT display at 1024x600 (16-bit grayscale), MEGA CHIRP in Full (150-220 kHz)/Narrow (180-240 kHz)/Wide (140-200 kHz) modes plus an optional 28-250 kHz range, MEGA Side Imaging+ at 1050-1175 kHz, MEGA Down Imaging+ at 1100-1200 kHz, legacy 50/83/200/455/800 kHz support, a built-in GPS receiver with Humminbird Basemap (10,000+ lakes plus US coastal coverage) preloaded, Ethernet/NMEA 2000/Bluetooth/Wi-Fi networking, and One-Boat Network compatibility. A separate targeted text search of the same page for 'touch'/'keypad' returned: 'Keypad control: Master HELIX at the touch of a button... operated by soft key controls', confirming physical-button (not touchscreen) operation.
