Navico StructureScan 3D® Stainless Steel Thru-Hull Transducer - Pair

Transform Your Boating Experience with Advanced 3D Sonar Imaging

Imagine gliding across the water, your boat's hull slicing through waves, while a vivid, lifelike picture of the underwater world unfolds on your display. That's the power of the StructureScan 3D Stainless Steel Thru-Hull Transducer pair. Crafted specifically for vessels with steep or fluctuating deadrise angles—think performance boats or deep-V hulls—these robust transducers deliver unmatched clarity in SideScan, DownScan, and immersive 3D views. Anglers who chase bass in tangled weed beds or hunt offshore wrecks swear by this setup, as it pinpoints fish holds, submerged timber, and subtle bottom shifts with precision that flat 2D sonar just can't match.

What sets these apart? Multi-beam sonar technology scans far wider and deeper than standard setups, revealing structure up to 600 feet port and starboard for SideScan, and down to 300 feet for DownScan. The stainless steel construction laughs off corrosion in saltwater marathons, ensuring reliable performance season after season. No more guessing where the big ones lurk—see them in context relative to your boat's position, making split-second decisions on lure choice or drift adjustments a breeze.

Technical Specs Tailored for Serious Boaters

• Mounting Style: Thru-hull for seamless integration into hull bottoms with 16-24 degree deadrise.
• Scanning Range: Expansive 600 feet per side (SideScan) and 300 feet depth (DownScan).
• Power Output: 500 watts to punch through murky water or heavy cover.
• Operating Frequency: 455 kHz for sharp, detailed returns.
• Cable: 30-foot length included, with options for extensions if needed for larger consoles.
• Design Highlights: Low-profile pods reduce drag at speed; includes fairing block option for optimal alignment.

These specs aren't just numbers—they translate to real advantages. The separate port and starboard units create a stereo-like 3D effect, boosting resolution and eliminating the shadows common in single-transducer systems. Pair them with compatible chartplotters, and you'll enjoy boosted 2D DownScan and StructureScan HD performance too.

Why Thru-Hull Mounting Wins for High-Performance Boats

For boats with aggressive hull shapes, transom mounts often compromise on angle and accuracy due to turbulence or poor deadrise fit. Thru-hull installation positions the transducers dead ahead of prop wash, capturing pristine data even at trolling speeds or planing. The stainless steel housing from premium manufacturers withstands galvanic action in brackish bays, while the fairing block ensures a flush fit that maintains hull speed.

Pro tip for installers: Align the transducers parallel to the waterline using the included block, and you'll maximize beam coverage. This setup shines in variable conditions, from shallow flats to deep drop-offs, helping you spot bait balls schooling tight to ledges or crayfish scuttling along rocky bottoms.

Real-World Benefits for Everyday Anglers and Captains

Picture this: You're dialing in on a school of walleye hugging a mid-lake hump. Traditional sonar shows blobs; StructureScan 3D renders it in 3D glory, letting you measure exact distances and heights. Offshore? Track wrecks layer by layer, distinguishing snags from trophy hideouts. The enhanced bottom discrimination separates sand from mud, gravel from rock—critical for jigging or trolling tactics.

Maintenance is straightforward: Rinse after saltwater use, inspect cables for chafe, and store dry. This durability means fewer breakdowns mid-trip, more fish in the box. Saltwater pros appreciate the electrical resistance, fending off interference from bilge pumps or radios.
