Navico StructureScan 3D Thru-Hull Transducer Fairing Block Only

Unlock superior underwater imaging on your vessel with the precision-engineered fairing block designed exclusively for the StructureScan 3D thru-hull transducer. This high-performance component transforms how you navigate and fish by minimizing drag and ensuring crystal-clear sonar scans even when pushing your boat to higher speeds. Anglers and mariners who demand reliable structure and fish-holding detail without compromising on velocity will find this fairing block indispensable for offshore adventures or tournament pursuits.

Streamlined Design for Peak Performance

Crafted from durable, marine-grade materials, this fairing block contours perfectly to the hull's underwater profile. It channels water flow smoothly over the transducer face, drastically reducing turbulence that often plagues standard thru-hull installations. The result? Consistent, high-resolution 3D side-imaging and down-imaging from StructureScan, revealing hidden wrecks, drop-offs, and bait schools with unmatched clarity—whether you're idling in shallow bays or cruising at planing speeds.

• Drag Reduction: Up to 50% less hydrodynamic resistance compared to non-faired setups, based on real-world testing in varied sea conditions.
• Enhanced Signal Quality: Maintains optimal transducer angle for broader coverage and sharper imagery at speeds over 20 knots.
• Robust Construction: Withstands constant exposure to saltwater, UV rays, and impacts from debris.

Seamless Integration and Installation Insights

Installing this fairing block is straightforward for DIY boaters or professionals alike. Position it to align with your thru-hull transducer's mounting flange, securing it with high-strength marine adhesives or mechanical fasteners for a flush, hydrodynamic fit. Key pro tip: Angle the block slightly forward (about 10-12 degrees) to match your hull's deadrise, optimizing water flow and preventing air pockets that distort sonar returns. This setup not only boosts StructureScan 3D performance but also extends transducer lifespan by shielding it from direct wave slap.

For multi-transducer arrays, this fairing pairs effortlessly with forward-facing sonar or traditional transducers, creating a clean, low-profile installation that preserves your boat's sleek lines and fuel efficiency.

Why Boaters Choose This Fairing Block

In the world of advanced marine electronics, generic fairings fall short on precision. This model stands out by being purpose-built for StructureScan 3D's unique transducer shape, delivering side-scan views up to 300 feet per side without the "shadowing" artifacts common at speed. Tournament anglers report spotting fish-holding brush piles and rock formations they previously missed, while cruisers appreciate the quieter ride and stable imaging during long passages. It's not just an accessory—it's a game-changer for serious on-water operations.

Maintenance for Long-Term Reliability

Keep your setup performing like new with simple care routines. After each outing, rinse with fresh water to flush away salt buildup, and inspect for marine growth—common in warmer waters. A quick wipe-down with a non-abrasive cleaner preserves the smooth surface critical for laminar flow. Over time, this fairing block proves its value by preventing costly transducer replacements due to erosion or misalignment.
