Humminbird MEGA 360 Imaging for Ultrex / Ultrex QUEST

The Humminbird MEGA 360 Imaging transducer for Ultrex and Ultrex QUEST (part 411830-1) is the bow-mount add-on transducer that gives Ultrex-equipped bass and walleye boats a continuous 360-degree picture-quality view of fish, structure, and bottom around the entire boat. The transducer mounts to the Ultrex (or QUEST brushless variant) trolling motor via the included anodized aluminum bracket, with the transducer shaft hanging below the motor head independently of the motor's prop assembly. The result: the 360-degree sonar image stays correctly oriented to the boat regardless of which way you steer the trolling motor and regardless of whether you're holding Spot-Lock against wind and current. Continuous 360 view, never interrupted by trolling motor turns.

What MEGA 360 Imaging actually shows. The transducer rotates continuously (you'll hear it as a soft sweep noise underneath the boat) sending high-frequency MEGA-CHIRP sonar pulses out around the boat in a complete 360-degree pattern. The compatible HELIX, SOLIX, or APEX head unit assembles the returns into a top-down picture-quality image showing structure (laydowns, brush piles, dock pilings, weed lines), fish (individual marks at any depth in the boat's surrounding cone), and bottom contour - all radiating outward from the boat's position at the center of the screen. The view updates several times per minute as the transducer completes each sweep. Range typically 75-125 feet outward depending on water depth and clarity.

Why mount it on the trolling motor independently. The earlier-generation MEGA 360 transducer mounted on the trolling motor barrel where it rotated WITH the motor as you steered. Result: the sonar image rotated on the screen every time you turned the trolling motor, which made it hard to track structure orientation. The Ultrex Quest variant mounts on a fixed bracket that doesn't rotate with the trolling motor head - the transducer stays pointing the same way regardless of which way the motor is steered. The 360-degree image stays north-up (or boat-up, depending on the screen orientation setting) consistently. Much easier to use for active fishing where you're frequently turning the trolling motor.

Two operation modes. The 411830-1 transducer can run in either MEGA 360 Imaging mode (the rotating top-down view described above) or MEGA Side Imaging mode (the more familiar side-imaging horizontal view to either side of the boat). Switch modes from the head unit menu based on the fishing situation. Some anglers run MEGA 360 Imaging for active casting around the boat and switch to MEGA Side Imaging when running over structure to map a longer linear bottom track. Same transducer hardware, two display modes selectable on demand.

Compatible HELIX G3N and G4N MEGA SI+ / DI+ models. The list of HELIX models that support MEGA 360 Imaging from this transducer is specific - it requires the MEGA Imaging+ generation HELIX G3N or G4N units. Compatible HELIX models include HELIX 8, 9, 10, 12, and 15 in the MEGA SI+ GPS G4N or G3N variants, plus the MEGA DI+ variants in 9, 10, 12, and 15. Older HELIX units without MEGA Imaging+ support don't run the 360 Imaging mode (those can still use the transducer in side-imaging mode but won't display the rotating 360 view).

Compatible APEX and SOLIX models. All current APEX and SOLIX G2 and G3 units support MEGA 360 Imaging from this transducer. APEX is Humminbird's flagship touchscreen line. SOLIX is the established touchscreen line. For boats running APEX or SOLIX as the primary fish finder, the MEGA 360 Imaging view appears alongside the rest of the sonar suite (Dual Spectrum CHIRP, MEGA Side Imaging, MEGA Down Imaging, and chart) on the touchscreen.

Compatible trolling motors. Ultrex and Ultrex QUEST trolling motors specifically. The 411830-1 transducer is engineered with the bracket geometry and mounting interface for the Ultrex platform's bow mount design. For other trolling motors (PowerDrive, Terrova, etc.), this specific transducer SKU isn't the right fit - check the Humminbird MEGA 360 transducer line for the variant that matches your specific trolling motor.

What's in the box. Ultrex bow-mount MEGA 360 Imaging transducer with attached power cable and transducer cable. 10-foot SOLIX transducer cable (for SOLIX / APEX network connection). 10-foot HELIX transducer adapter cable (for HELIX direct-connect). 10-foot MEGA 360 power cable. Easy-to-mount MEGA 360 Imaging - Ultrex mounting bracket (anodized aluminum). Install instructions. Trolling motor sold separately.

Network sharing. Once connected to a compatible HELIX G3N MEGA Imaging+ or SOLIX G2 unit, the MEGA 360 Imaging view can be shared with all SOLIX, all HELIX G2N, and all HELIX G3N units on the boat's Ethernet network. So a multi-display helm with one bow-mount unit running 360 plus a console-mount unit can both see the 360 view simultaneously.

Customizable display. Sweep speed (faster vs. slower rotation), viewing area (full 360 or partial sector), display information (range rings, distance markers, target counts), sonar zoom, and color palette - all customizable to your specific fishing situation and preferences. Most anglers spend a session or two figuring out their preferred settings, then leave them alone.

Range rings. Optional range rings overlay distance markers on the 360 Imaging screen so you can see how far targets are from the boat. Useful for translating screen position to actual cast distance: target at 50 feet on the screen = aim a 50-foot cast in that direction.

Waypoint marking. Mark waypoints directly on the MEGA 360 Imaging screen with a touch (or button press, depending on the head unit). The waypoint stays at the marked GPS coordinate as your boat moves, so you can reposition and cast to the marked spot from a different angle. Useful for marking individual fish you spotted on the 360 view to come back to after the current presentation.

Pair with multiple sonar views. View MEGA 360 Imaging alongside MEGA Side Imaging, MEGA Down Imaging, Dual Spectrum CHIRP 2D, and chart in multi-pane layouts on the head unit. The 360 view is one tool in the broader Humminbird sonar suite, not a replacement for the other views.

Specs. Transducer shaft length: 39 inches (matches typical Ultrex shaft submersion). Weight: 12 lb. Mounting bracket material: anodized aluminum (corrosion-resistant for marine environment). Cable lengths: 10 ft SOLIX, 10 ft HELIX adapter, 10 ft power.

2-year limited Humminbird warranty. Same-day shipping before 3 PM ET on in-stock units.
