Raymarine B175H-W 20° Bronze Thru-Hull Tilted Element Transducer - 1kW Professional CHIRP Sonar
A80321A80321723193796276
Professional-grade thru-hull transducer engineered for serious fishing performance. The Raymarine B175H-W features a precision-angled 20° tilted ceramic element in durable bronze housing, delivering 1kW CHIRP sonar power with wide beam coverage for exceptional fish detection and bottom imaging on boats with 16-24° deadrise hulls.
Why Tournament Anglers Choose the B175H-W
? 20° Tilted Element Technology
Precision-engineered ceramic element tilted at 20° compensates for hull deadrise angle, ensuring optimal sonar beam orientation perpendicular to the water surface for maximum echo strength and accuracy.
⚡ High-Power 1kW CHIRP Performance
1000-watt RMS power delivers exceptional depth penetration up to 800 feet with crystal-clear target separation. Wide CHIRP frequency range (150-250 kHz) provides detailed fish arches and bottom structure imaging.
?️ Professional Bronze Construction
Marine-grade bronze housing with urethane lens provides superior durability and longevity in harsh saltwater environments. Low-profile design minimizes drag and turbulence at speed.
? Wide Beam Coverage
25° beam width delivers excellent shallow water coverage while maintaining high-resolution target identification. Ideal for both offshore trolling and inshore structure fishing applications.

Advanced Performance Features
Tilted Element Advantage
The factory-calibrated 20° element tilt ensures the sonar beam projects perpendicular to the water surface on hulls with 16-24° deadrise. This optimal beam angle maximizes echo return strength, improves target resolution, and provides accurate depth readings even at speed.
Wide CHIRP Technology
Operating across 150-250 kHz frequency range, the B175H-W delivers superior target separation and fish identification compared to traditional single-frequency transducers. CHIRP technology provides enhanced bottom detail and distinguishes between fish species and size classes.
High-Power Performance
1000-watt RMS power ensures strong signal penetration through thermoclines and deep water, maintaining clear bottom definition and fish detection at maximum rated depth of 800 feet. Ideal for deep offshore fishing and commercial applications.
Frequently Asked Questions
How do I know if my boat's deadrise is compatible with the 20° tilt?
The B175H-W is designed for hulls with 16-24° deadrise angles. Measure your hull's deadrise angle at the intended installation location. If your deadrise is outside this range, consider alternative transducer models with different tilt angles or adjustable mounting options.
Why do I need an extension cable for installation?
The B175H-W includes only a 6-foot pigtail cable. Most installations require routing from the thru-hull location to the helm or electronics area, necessitating a 10-meter extension cable (A80327 or A80328). This design prevents cable damage during installation and allows flexible routing.
Can this transducer be used on metal hulls?
The B175H-W is approved only for fiberglass and wood hulls. Metal hulls require specialized transducers designed to work through metal or external mounting solutions. Contact Raymarine for metal hull compatible alternatives.
What's the difference between this and other B175 models?
The B175H-W features wide beam CHIRP technology (150-250 kHz) and a 20° tilted element for specific deadrise hulls. Other B175 models may have different tilt angles, frequency ranges, or beam patterns. The "H-W" designation indicates High/Wide CHIRP capability.
How often should the transducer be cleaned or maintained?
Bronze transducers naturally resist marine growth, but periodic cleaning with non-abrasive marine cleaners maintains optimal performance. Inspect annually for damage, growth, or paint buildup. Avoid pressure washing directly on the transducer face, and never use steel wool or abrasive cleaners that could damage the urethane lens.
