Humminbird HELIX 8® MDI w/MEGA 360 Ultrex — Product description

Imagine casting your line with absolute confidence, knowing exactly what's lurking around your boat in every direction. The Humminbird HELIX 8 MDI paired with MEGA 360 Ultrex transducer delivers that game-changing edge for serious anglers. This powerful combo fuses an 8-inch high-resolution display with cutting-edge sonar technology, giving you crystal-clear views below and a full 360-degree sweep around your vessel. Whether you're chasing bass in shallow weeds or hunting walleye in deeper waters, this setup uncovers fish and structure like never before.

Unlock Superior Clarity with MEGA Down Imaging and Dual Spectrum CHIRP

At the heart of the HELIX 8 CHIRP MEGA DI GPS G4N is its ability to paint the underwater world in stunning detail. MEGA Down Imaging pushes boundaries, revealing details down to 125 feet with up to three times the fish ID detail of traditional Down Imaging. Spot subtle bottom changes, suspended baitfish schools, or trophy walleye hugging the floor—nothing escapes your screen.

Dual Spectrum CHIRP sonar adapts to your needs on the fly. Switch to wide mode for broad coverage to quickly locate hotspots, or zoom in with narrow mode for pinpoint precision on fish arches and cover. Powered by a low-Q CHIRP transducer, it separates targets effortlessly, even in murky water where standard sonar falls short.

Seamless Navigation and Mapping on the Water

Built-in GPS and Humminbird Basemap mean you're never lost or guessing. Chart over 10,000 lakes with contours, depth highlights, hazards, marinas, and buoys for the U.S. interior and coasts. Upgrade to premium charts like LakeMaster or Navionics for even richer detail.

AutoChart Live turns your boat into a mapping machine. As you cruise, record custom depth contours, bottom hardness, and vegetation—up to eight hours standard, expandable with SD cards. It's like having a personal hydrographer, helping you revisit hot spots season after season.

Effortless Control in Any Conditions

The intuitive keypad and soft-key menu shine in rough weather. Gloved hands or wet fingers? No problem. Access sonar views, adjust settings, and mark waypoints with precision, keeping your focus on the fish.

MEGA 360 Imaging Ultrex: 360-Degree Awareness Without Compromise

Mount this transducer on your Minn Kota Ultrex trolling motor, and gain a revolving sonar panorama that updates continuously. High-frequency MEGA Imaging CHIRP sweeps the megahertz range, delivering photo-like images of fish, brush piles, and drop-offs up to hundreds of feet away—all while your motor handles Spot-Lock or trolling duties uninterrupted.

Flexibility is key: toggle between full 360-degree sweeps or MEGA Side Imaging mode. Customize sweep speed, range rings for distance gauging, color palettes, and zoom to match lake conditions. Mark waypoints right on the 360 view—they dynamically update with your position for dead-accurate casts.

Stay Connected and in Command

Ethernet networking builds a pro-level system—share views across HELIX and SOLIX units, add i-Pilot Link for spot-on boat control, or integrate CHIRP Radar. Bluetooth pairs with Talon/Raptor anchors and Cannon downriggers for wireless tweaks, software updates via FishSmart app, and phone alerts. NMEA 2000 pulls in engine data, weather, and more. Wi-Fi enables quick updates and One-Boat Network synergy with Minn Kota and Cannon gear.

Why Anglers Swear by This Setup

Real-world users rave about how it transforms outings. Tournament pros use the 360 view to scout coves without spooking fish, while family fishers appreciate the ease of finding stocked ponds. The independent Ultrex mount means no downtime—fish windy days with Spot-Lock holding steady as imaging spins flawlessly. Durable anodized bracket and 39-inch shaft handle abuse, weighing just 12 pounds for easy install.

Everything arrives ready: control head, transom transducer, mounting kit, cables, and gimbal bracket. Backed by a two-year warranty, it's built to last through countless adventures.
