Discover Superior Underwater Visibility with Precision Engineering

Navigating challenging waters demands transducers that cut through hull deadrise challenges without compromising signal clarity. Designed for vessels with moderate to steeper hull angles, this stainless steel thru-hull model delivers robust 600-watt power across dual frequencies, ensuring crisp images of fish, structure, and bottom contours even in rough conditions. Boat owners with hulls in the 16° to 24° deadrise range appreciate how the internal tilted ceramic element automatically aligns the beam for optimal downward projection, eliminating the guesswork in installations.

Whether you're targeting trophy species in deep offshore runs or scanning shallows for bait schools, the wide beam at lower frequencies sweeps broad areas while the narrow high-frequency beam pinpoints details with laser-like focus. Integrated temperature sensing adds another layer of utility, helping anglers correlate water conditions with fish behavior patterns for smarter decisions on the water.

Engineered for Real-World Boating Demands

Dual-Frequency Versatility: Seamlessly switch between 50 kHz for expansive coverage and 200 kHz for high-resolution targeting, adapting to diverse fishing scenarios from coastal reefs to open ocean.
Beam Optimization: 20° beam at 50 kHz captures vast underwater landscapes; 6° at 200 kHz reveals fine details like individual fish separation and wreck features.
Corrosion-Resistant Build: Marine-grade stainless steel housing withstands saltwater exposure, impacts, and years of heavy use without signal degradation.
Flush-Mount Design: Minimizes drag and turbulence, preserving your boat's speed and fuel efficiency while maintaining a sleek hull profile.
Extended Reach: 30-foot cable provides flexible routing options through bulkheads and consoles, simplifying professional or DIY setups.

Why Tilted Element Matters for Your Hull

Hulls aren't flat—deadrise angles distort traditional transducer beams, leading to weak returns and missed targets. This model's pre-angled ceramic compensates precisely for 16°-24° deadrises, directing energy straight down regardless of installation side. Spot the alignment arrow on the housing: point it keel-ward for foolproof orientation, ensuring maximum performance from day one.

Unlock Deeper Insights Beneath the Surface

Anglers report consistently sharper arches and cleaner bottom tracking compared to non-tilted alternatives, thanks to the 600-watt output punching through thermoclines and sediment. In tandem with modern multifunction displays, it excels at marking subtle structure like suspended bait balls or ledge drops that spellbite success. Temperature data overlays help track currents and upwellings, turning raw sonar into actionable intel for trolling patterns or drift fishing.

For trailered boats, the durable flush design shrugs off ramps and beaching, while the stainless construction laughs off electrolysis in brackish environments. Pair it with your existing electronics via the standard 10-pin connector for plug-and-play reliability—no adapters needed.

Proven Installation Strategies for Peak Results

Prep your thru-hull site with a clean, fair hull surface free of strakes or thru-hulls that could shadow the beam. Use a hole saw for a precise fit, bed in non-hardening sealant, and torque to spec for a watertight bond. Route the cable away from engines and radios to dodge interference, securing with ties for longevity.

"The tilt correction transformed my readings—fish that were ghosts now pop like fireworks." – Experienced offshore captain

Regular hull cleaning prevents marine growth from attenuating signals, and annual connector checks keep connections crisp. This transducer's ruggedness means less downtime, more time chasing limits.

Seamless Integration Across Gear

Engineered to thrive with a range of chartplotters and sounders, it feeds clean data to systems craving high-power thru-hull inputs. Verify your unit's connector match, and you're set for enhanced CHIRP-like performance in conventional mode. Ideal for center consoles, sportfishers, and walkarounds where deadrise demands precision.

Frequently Asked Questions

If a thru-hull flush-style 600W transducer is what you need, the Tilted Element 555T-LTD/12 will accommodate a deadrise angle between 8 and 15 , while the Tilted Element 555T-LTD/20 is right for hulls with a deadrise angle of between 16 and 24 . Both of these transducers compensate for deadrise by angling the element inside the housing.
The transducer is labeled with an arrow on top of the housing that should point towards the keel, whether it is installed to port or starboard. This ensures that the tilted element within the housing is given the correct orientation.
