Humminbird SOLIX® 15 CHIRP MEGA SI+ G3 CHO Display Only Product Description

Discover Unmatched Clarity on the Water with Advanced Fish Finding Technology

Imagine pinpointing fish and structure with razor-sharp detail, even in the murkiest waters or at depths up to 250 feet. The Humminbird SOLIX 15 CHIRP MEGA SI+ G3 CHO delivers that edge for serious anglers who demand precision. This control head only unit pairs seamlessly with your choice of transducers, including high-end options like MEGA 360 or integrated Minn Kota trolling motors, letting you customize your setup for any boat or fishing style. Whether you're chasing bass in shallow bays or walleye in deep reservoirs, its industry-leading sonar suite transforms guesswork into targeted strikes.

Revolutionary Imaging That Reveals Every Detail

MEGA Side Imaging+ and MEGA Down Imaging+ push boundaries with 20% more detail than previous generations, scanning up to 200 feet to each side and below your boat. Spot subtle bottom changes, submerged timber, or schools of baitfish that traditional sonar misses. Dual Spectrum CHIRP sonar adds exceptional 2D clarity, separating fish from cover with compressed high-intensity pulses across wide frequencies. Real-world anglers report landing trophy fish by interpreting these hyper-detailed views during live-action scouting—perfect for tournament pros dialing in patterns quickly.

Seamless Mapping and Navigation for Confident Exploration

Built-in GPS and Humminbird Basemap cover over 10,000 freshwater lakes with contours, plus U.S. coastal charts highlighting hazards, marinas, and depth markers. Dive deeper with AutoChart Live, which lets you map bottom hardness, vegetation, and contours in real-time as you motor along. Store up to 8 hours of data internally or expand with Micro SD cards for endless custom maps. Pair with premium charts to unlock seasonal fish-holding zones, saving hours of pre-fish scouting and boosting your catch rates on unfamiliar waters.

Intuitive Controls Tailored to Your Fishing Flow

The 15.4-inch ultra-clear display boasts 1280x800 resolution for vibrant, sunlight-readable views. Cross Touch lets you switch effortlessly between touchscreen swipes and keypad precision, ideal for gloved hands or rough seas. A dual-core processor ensures lightning-fast response, while the sidebar menu and customizable screens let you stack sonar, imaging, and maps exactly how you need them. No more fumbling—access MEGA Live for real-time motion video of fish reacting to your lure.

Build Your Ultimate Connected Fishing System

Networking is where this unit shines: Ethernet for sharing data across heads, Wi-Fi for updates, Bluetooth for controlling anchors or downriggers, and NMEA 2000 for engine stats and weather feeds. Integrate into the One-Boat Network with Minn Kota for spot-lock precision or Cannon for automated trolling. It's waterproof, rugged, and ready for multi-unit setups, making it a cornerstone for professional-grade boats chasing big water success.

Practical Tips for Maximizing Your Setup

• Mount the gimbal bracket flush for optimal viewing angles, ensuring the power cable routes cleanly to avoid snags.
• Combine with high-kHz transducers for shallow water finesse or low-kHz for deep structure hunting.
• Use waypoint clustering to mark hot spots efficiently, revisiting them season after season.
• Fine-tune sensitivity during dawn/dusk bites when fish activity peaks for cleaner arches.
