Raymarine HV-300TH Plastic Transducer Thru-Hull Pair - 6M Cable — Product description

Upgrade your boating experience with the Raymarine HV-300TH plastic thru-hull transducers, designed for boaters who demand precision in shallow waters and tight spots. This pair delivers stunning HyperVision sonar imaging, blending high-frequency CHIRP technology with real-time 3D views to reveal what's ahead, below, and around your vessel. Whether you're navigating rocky coastlines or hunting structure for trophy fish, these transducers cut through murky conditions like a knife, providing clarity that standard sonar just can't match.

Unmatched Sonar Performance

Crafted for serious anglers and navigators, the HV-300TH pair operates across multiple frequencies to handle diverse underwater scenarios. At 200kHz, you'll get reliable bottom tracking for deeper profiling. Switch to 350kHz for razor-sharp DownVision that maps lakebeds and riverbeds with incredible detail. Then, unleash 1.2MHz SideVision for wide-angle sweeps that spot fish hiding in cover or structure up to impressive ranges. The result? A forward-looking perspective that helps you avoid hazards and zero in on prime fishing grounds without guesswork.

Why Choose Plastic Thru-Hull Design?

Plastic construction keeps things lightweight and corrosion-resistant, ideal for fiberglass hulls common on recreational boats and center consoles. Unlike heavier metal options, these won't stress your mounting points over time, and they transmit signals cleanly without distortion. The 6-meter cable gives you flexible routing through bulkheads and consoles, minimizing signal loss. Boaters love how they blend seamlessly into the hull line, maintaining your boat's sleek profile while delivering pro-level sonar data.

  • Pair Configuration: One transducer per side for balanced, comprehensive coverage—port and starboard views without blind spots.
  • High-Resolution Imaging: HyperVision's 3D rendering turns flat sonar screens into dynamic, navigable maps.
  • Shallow Water Specialist: Excels in depths as low as a few feet, perfect for inshore fishing or exploring bays.
  • Plug-and-Play Ready: Direct compatibility with Raymarine's latest multifunction displays for quick setup.

Real-World Benefits for Everyday Boaters

Imagine threading through a kelp forest at dawn, watching live 3D images of boulders and drop-offs unfold on your screen. Or, during a tournament, pinpointing schools suspended over reefs that 2D sonar misses entirely. These transducers don't just show fish—they reveal their behavior, letting you drop baits exactly where it counts. Fuel savings come from smarter pathfinding, and safer passages build confidence on unfamiliar waters. Saltwater anglers report fewer snags and more hookups, while freshwater enthusiasts swear by the crystal-clear wreck and stump detection.

Pro Tips for Installation Success

Mounting thru-hull transducers might sound intimidating, but with the right approach, it's a weekend warrior project. Start by selecting dead-rise-matched fairing blocks to keep the face perpendicular to the waterline—critical for accurate beams. Drill a precise 2-inch hole (check your hull thickness first), bed the unit in marine sealant, and secure with a backing nut. Route the 6m cable away from engines and props to dodge interference. Test in a bucket of water before launch to confirm pings. Common pitfalls? Angled mounts causing beam skew—always use a digital level. For twin setups, space them 1-2 feet apart amidships for optimal overlap.

Maintenance That Keeps It Performing

Keep your HV-300TH pair humming by wiping down with fresh water after every saltwater trip. Inspect the face for marine growth quarterly; a soft brush and eco-friendly cleaner do wonders. In winter storage, dry thoroughly and store cables coiled loosely. If fouling persists, consider anti-fouling paint compatible with plastic housings. Regular checks ensure peak signal strength season after season, avoiding costly replacements.

When HyperVision Shines Brightest

These transducers transform bay boats, flats skiffs, and sportfishers into sonar powerhouses. Offshore? Pair with lower-frequency probes for hybrid setups. Inland lakes? Their high frequencies dominate weedy shallows. Kayak anglers scaling up to larger hulls find them a game-changer for spotting bass beds. No matter your pursuit—crappie jigging, stripper trolling, or wreck diving—the HV-300TH elevates your edge.

Frequently Asked Questions

What frequencies does the Raymarine HV-300TH transducer pair support?

The pair operates at 200kHz for traditional CHIRP, 350kHz for DownVision, and 1.2MHz for SideVision and forward HyperVision scanning, providing versatile imaging options.

Is the HV-300TH suitable for thru-hull mounting on fiberglass boats?

Yes, the plastic housing is lightweight and ideal for fiberglass hulls, transmitting sonar signals efficiently without corrosion issues.

What is the cable length included with this transducer pair?

Each transducer comes with a 6-meter cable, offering ample length for routing to your display unit through consoles and bulkheads.

Why choose a pair of HV-300TH transducers over a single unit?

A pair provides port and starboard coverage simultaneously, eliminating blind spots and delivering full 3D HyperVision sweeps for comprehensive underwater awareness.

Can these transducers handle shallow water environments?

Absolutely—the high-frequency bands excel in shallow waters, offering detailed imaging down to just a few feet, perfect for flats fishing and inshore navigation.

How do I maintain the plastic thru-hull transducers?

Rinse with fresh water after use, clean growth with a soft brush, and inspect mounts seasonally to ensure optimal performance and longevity.

Are fairing blocks required for installation?

Fairing blocks are recommended to match your hull's deadrise angle, ensuring the transducer face is perpendicular to the water for accurate readings.
