Navico TotalScan Thru-Hull Transducer Medium/High CHIRP, DownScan, StructureScan HD®

Upgrade your fishing setup with the versatile TotalScan Thru-Hull Transducer, designed for serious anglers chasing bigger catches in deeper waters. This all-in-one powerhouse combines medium and high CHIRP sonar, DownScan Imaging, and StructureScan HD into a single unit, eliminating the clutter of multiple transducers while delivering crystal-clear underwater visuals. Mounted through the hull, it provides a clean, streamlined installation that's perfect for boats with flat bottoms or moderate deadrise angles up to 5 degrees when paired with a fairing block.

Unlock Superior Fishfinding Performance

Imagine scanning vast areas with wide-coverage broadband sonar at 83/200 kHz, then zooming in on precise targets using medium and high CHIRP frequencies for exceptional target separation. Add DownScan's photo-like imaging and StructureScan HD's side-to-side detail up to 300 feet, and you've got a complete picture of the underwater world. At 500 watts of power, it punches through to 1000 feet on CHIRP modes, making it ideal for offshore adventures or deep inland lakes where fish hide in complex structures.

Key Advantages for Thru-Hull Mounting

Unlike transom-mounted options that drag in the water and pick up turbulence, thru-hull designs like this one sit flush for optimal signal quality at high speeds. The 9-pin connector ensures easy integration with compatible Simrad, Lowrance, and B&G fishfinders. It even senses water temperature, helping you track thermoclines where baitfish—and predators—congregate.

• Multi-Function Capability: Broadband (83/200 kHz), Medium/High CHIRP, 455/800 kHz StructureScan, DownScan Imaging
• Impressive Range: 1000 ft (CHIRP), 300 ft (StructureScan)
• Rugged Build: Built for marine environments with reliable performance season after season
• Streamlined Setup: Single transducer reduces wiring hassles and boat modifications

Perfect for Real-World Fishing Scenarios

Whether you're trolling for walleye in 200 feet of water or hunting bass around submerged timber, this transducer shines. High CHIRP excels at separating individual fish in schools, while StructureScan HD reveals wrecks, drop-offs, and brush piles from afar. Pair it with your chartplotter for overlay views that pinpoint hotspots, saving time and fuel on every trip. Anglers report spotting fish closer to the bottom and navigating tight structure with confidence, turning good days into limits.

Installation Tips for Peak Results

Selecting the right spot is crucial—aim for forward of the prop and keel line to avoid bubbles. For hulls with deadrise, use the included fairing block to angle it properly for a downward beam. Drill carefully, seal with marine sealant, and route the cable away from electrical noise sources. Test in shallow water post-install to fine-tune settings. Pro tip: In colder climates, insulate the thru-hull fitting to prevent freeze damage.

Why It Stands Out from Traditional Transducers

Most single-function units force compromises, but TotalScan delivers pro-level imaging without the premium price tag of separate high-end modules. It's lighter and more hydrodynamic than dual-band setups, improving boat efficiency. Compared to pod-style thru-hulls, its compact profile minimizes drag, and the all-in-one tech future-proofs your electronics investment.

Care and Longevity

Rinse with fresh water after saltwater use, inspect the face for growth, and store dry during off-seasons. Avoid antifouling paints on the active face to prevent signal loss. With proper maintenance, expect years of dependable service backed by a solid manufacturer warranty.
