Humminbird SOLIX® 12 CHIRP MEGA SI+ G3 CHO Display Only Product Description

Imagine gliding across the water, pinpointing fish-holding structures with crystal-clear detail up to 250 feet away, all while customizing your view to match the moment. The Humminbird SOLIX 12 CHIRP MEGA SI+ G3 CHO delivers that edge for dedicated anglers who demand flexibility in their setups. As a control head-only unit, it empowers you to pair it with your preferred transducer, MEGA 360 Imaging module, or even a Minn Kota trolling motor with built-in MEGA Imaging—perfect for upgrading existing systems or tailoring a pro-level rig without redundancy.

Revolutionize Your Sonar Game with MEGA Imaging+

At the heart of this powerhouse lies industry-leading sonar that transforms how you scout the underwater world. MEGA Side Imaging+ and MEGA Down Imaging+ paint hyper-detailed pictures of structure, baitfish schools, and trophy gamefish, revealing nuances like suspended walleye near drop-offs or crappie hugging brush piles. Dual Spectrum CHIRP sonar excels in 2D views, offering razor-sharp target separation that cuts through thermoclines and clutter—think cleaner arches on bass in 30 feet or separating individual perch from weeds.

Supporting frequencies from 83/200 kHz for broad coverage to ultra-high 455/800/1200 kHz for fine detail, it adapts to any waterbody, from vast reservoirs to tight inland lakes. Anglers report consistently spotting more fish in challenging conditions, like murky rivers post-rain, where traditional sonar falls short.

Cross Touch Interface: Control on Your Terms

Say goodbye to fumbling in rough seas or with gloves on. The 12.1-inch ultra-clear touchscreen pairs with a responsive keypad for hybrid control—navigate menus, split-screen views, or zoom sonar returns via either method. The sidebar menu and intuitive interface let you stack sonar panes, charts, and camera feeds exactly how you fish, whether tournament-style multitasking or relaxed walleye hunts.

A new dual-core processor turbocharges everything, slicing through heavy data loads for lag-free performance. Scroll charts smoothly at speed or render MEGA images instantly, even with multiple units networked.

Build Your Ultimate Fishing Network

Ethernet networking lets you daisy-chain units for shared sonar data, adding radar or i-Pilot Link for spot-lock precision. Built-in NMEA 2000 pulls in engine stats, weather feeds, or water temp, while Bluetooth connects to shallow-water anchors for one-touch deployment or displays phone alerts without distraction. Wi-Fi enables over-the-air updates via the FishSmart app, keeping you current without docksides.

One-Boat Network integration shines with Minn Kota and Cannon gear—control heading sensors, deploy downriggers, or auto-chart while spot-locked. CZone digital switching compatibility adds boat-wide automation, like lights or pumps from the fish finder screen.

Master Mapping and Navigation

Internal GPS and enhanced Humminbird Basemap cover over 10,000 lakes with contours, hazards, marinas, and coastal U.S. details—zoom in on ramps or spot submerged timber effortlessly. AutoChart Live builds custom maps on the fly, logging depth, hardness, and veg as you troll, with 8 hours onboard storage expandable via SD cards.

Upgrade to LakeMaster or Navionics for high-def contours and shaded relief, unlocking features like Zero Lines for infinite detail. Veterans swear by it for dialing in hotspots, saving hours of blind searching.

Flexible Setup for Custom Rigs

This CHO model skips the transducer, freeing you to match XM series for deep water, AS HD for kayaks, or share from Ethernet peers. Mount via included gimbal bracket, plug in the power cable, and you're networked—ideal for multi-head boats or retrofits. A 2-year warranty backs your investment, ensuring reliability through seasons.
