Raymarine Low Profile Bronze Thru Hull 20D Tilt B164 7-Pin

Upgrade your marine electronics setup with a transducer that punches above its weight in challenging waters. Designed for boats navigating diverse conditions, this high-performance unit delivers crystal-clear sonar images without the bulk of traditional models. Its innovative low-profile housing hugs the hull seamlessly, ensuring minimal drag and maximum accuracy even on vessels with pronounced deadrise angles.

Superior Sonar Performance for Serious Boaters

Equipped with three internal ceramics, it harnesses full 1kW power to penetrate depths that lesser transducers can't touch. Switch effortlessly between low-frequency mode for wide-area scanning in deep offshore zones and high-frequency for pinpoint precision in shallower inlets. Anglers chasing trophy fish or navigators plotting safe passages appreciate the reliable depth and temperature readings that cut through thermoclines and murky bottoms alike.

• Dual-Frequency Versatility: 50 kHz for expansive 22° coverage down to 1,800 feet, and 200 kHz for focused 6° beams ideal for structure and bait schools up to 800 feet.
• Tilted Element Design: 20-degree compensation aligns perfectly with 16-24° deadrise hulls, eliminating distortion from off-angle mounting.
• Rugged Bronze Construction: Corrosion-resistant for saltwater endurance, approved for fiberglass and wood hulls.

Streamlined Installation and Reliable Connectivity

Mounting a thru-hull transducer demands precision, and this model's compact footprint simplifies the process on stepped or V-hulled boats. The 30-foot cable provides ample reach to your display unit, connecting via a robust 7-pin interface compatible with leading chartplotters. Once installed, it records essential data continuously, feeding your system with actionable insights for safer, more productive outings.

Pro tip: Pair it with high-end multifunction displays to unlock advanced features like CHIRP compatibility, where supported, enhancing target separation for species identification amid heavy cover.

Built for Real-World Demands

Whether you're tournament fishing in the Gulf Stream or coastal cruising with family, this transducer stands out for its balance of power and subtlety. Its deadrise-matched housing reduces turbulence, preserving hull speed while delivering sonar returns that reveal wrecks, ledges, and fish-holding sweet spots with exceptional clarity. Boaters report fewer false readings in rough seas, thanks to the stable low-profile form factor.

Maintenance Essentials for Longevity

To keep performance peaking, inspect the face annually for marine growth and clean gently with a soft brush and mild solution. Avoid high-pressure washers that could damage the epoxy lens. In extended layups, a light coat of anti-fouling paint on the exterior maintains its sleek operation without compromising internals.
