Humminbird HELIX 10® MEGA SI+ GPS G4N

Unlock Crystal-Clear Waters with Advanced Sonar Technology

Imagine gliding across your favorite lake, spotting fish hugging structure from over 200 feet away, and mapping new hotspots in real-time. That's the power packed into this fish finder, designed for serious anglers who demand precision and performance. With its expansive 10.1-inch high-resolution display, every detail—from subtle bottom contours to schools of baitfish—pops into view, helping you make smarter casts and land bigger catches.

Whether you're chasing bass in shallow bays or walleye in deep drop-offs, the enhanced imaging capabilities transform guesswork into targeted strategy. Anglers report filling limits faster thanks to the live-action views that reveal fish behavior as it happens, letting you adjust trolling speeds or jigging rhythms on the fly.

Superior Imaging: See More Fish and Structure Than Ever

The standout MEGA Side Imaging+ sweeps 200 feet to each side of your boat, delivering 20% sharper details and extended range compared to standard versions. Picture scanning submerged timber, rock piles, or weed edges with photo-like clarity—perfect for pinpointing ambush points where trophy fish lurk.

• MEGA Down Imaging+: Probes up to 200 feet straight down, uncovering fish suspended over open water or hugging the bottom with unmatched resolution.
• Dual Spectrum CHIRP Sonar: Switch between wide coverage for scouting vast areas and narrow focus for dissecting tight spots, revealing precise fish arches and bottom hardness.

Pro tip: In murky water, rely on the high-frequency CHIRP to cut through sediment, exposing hidden cribs or humps that hold crappie and perch during spawn.

Precision Navigation and Real-Time Mapping

Built-in GPS tracks your position with pinpoint accuracy, while the detailed Humminbird Basemap covers over 10,000 inland lakes and coastal U.S. waters. Spot hazards, marinas, and depth changes effortlessly, building confidence on unfamiliar waters.

• Store up to 2,750 waypoints to mark honey holes, saving hours of trial-and-error searching.
• AutoChart Live lets you generate custom contour maps, vegetation overlays, and hardness readings as you motor along—ideal for dialing in presentations on changing lakes.

Enhance your setup with compatible premium charts for even richer data, turning every outing into a mapping mission that pays dividends on return trips.

Seamless Connectivity for a Smarter Fishing System

Go beyond standalone use with robust networking options that integrate effortlessly into your rig. High-speed Ethernet supports multiple units and add-ons like precision trolling motors or radar for all-weather awareness.

• Bluetooth pairs with anchors and downriggers for wireless control from the screen.
• Wi-Fi and NMEA 2000 pull in boat data, weather feeds, and engine stats for a holistic dashboard.
• One-Boat Network compatibility unlocks synchronized features across brands, like spot-lock on brush piles or automated rigging depths.

Anglers love how this setup simplifies multi-species trips, coordinating sonar views with motor controls for hands-free efficiency.

Built Tough for Real-World Fishing Adventures

Rugged keypad controls shine in wet, gloved hands, ensuring reliable operation during rough chops or predawn launches. Fully waterproof construction laughs off splashes and spray, while the compact dimensions fit neatly on any console.
