Navico StructureScan 3D Thru Hull with L/H Chirp and StructureScan 3D

Imagine gliding across open waters with crystal-clear views of hidden reefs, schools of fish, and submerged structures right from your boat's helm. The StructureScan 3D Thru Hull transducer with L/H CHIRP and StructureScan 3D integration elevates your on-water adventures by delivering immersive, real-time underwater mapping that traditional 2D sonar simply can't match. Designed for serious anglers and navigators, this robust thru-hull mount captures detailed side and down imaging, helping you pinpoint prime fishing spots or avoid underwater hazards with confidence.

Superior Imaging Through CHIRP Technology

At the heart of this transducer lies dual Low/High CHIRP frequencies, which sweep across a broad spectrum of sound waves for unparalleled target separation and depth penetration. Unlike fixed-frequency sonars that miss fine details, CHIRP dynamically adjusts to provide sharper images of baitfish, wrecks, and bottom contours—even in murky waters. Paired with StructureScan 3D, it renders lifelike 3D perspectives, allowing you to rotate, tilt, and zoom into the underwater world as if you were diving below the surface.

• SideScan Range: Up to 300 feet per side for wide coverage.
• DownScan Precision: High-definition imaging straight down to reveal structure directly beneath your vessel.
• 3D Rendering: Intuitive views that make interpreting sonar data effortless for beginners and pros alike.

Versatile Thru-Hull Mounting for Any Hull Design

Engineered for thru-hull installation, this single transducer unit mounts flush to flat-bottomed hulls or adapts to moderate deadrises up to 5 degrees using the included fairing block. This setup minimizes drag, ensures optimal signal transmission, and withstands the rigors of saltwater exposure with its durable marine-grade construction. No more compromising on performance due to hull shape—achieve bubble-free water flow for consistent, high-quality scans.

Pro tip: During installation, align the transducer parallel to the waterline for maximum effectiveness. Anglers often position it forward of the running gear to avoid interference from props or keels.

Seamless Integration with Your Electronics Suite

Connecting is straightforward: The StructureScan 3D ports link directly to compatible modules, while the CHIRP connector—with built-in XID technology—plugs into your Multi-Function Display (MFD) via a standard 9-pin interface. This all-in-one design reduces wiring clutter and supports plug-and-play setup across popular marine networks. Whether you're running a compact setup or a full command center, it enhances your existing fishfinder without overhauling your system.

Real-World Advantages for Boaters and Fishermen

Boat owners rave about how this transducer transforms fishing trips into treasure hunts. Spot submerged timber where bass hide, map drop-offs for trolling runs, or survey channels for safe passage. Its sensitivity to small targets means you'll detect crappie schools or lobster pots that others overlook. In competitive tournaments, that edge can make all the difference—users report landing bigger catches by interpreting 3D overlays that reveal fish-holding structures invisible to the naked eye.

"Switched to this thru-hull unit last season and it's a game-changer. The 3D views helped me find a new honey hole loaded with walleye." – Experienced Great Lakes angler
