Raymarine B175H-W 1000W D/T Through Hull Wide Beam Transducer 0° Angle

Raymarine B175H-W 1000W D/T Through Hull Wide Beam Transducer

Raymarine B175H-W 1000W D/T Through Hull Wide Beam Transducer is a game-changing addition to your onboard electronics. Unlike traditional narrow-beam transducers, this 1kW powerhouse provides a constant 25° beamwidth across its entire frequency range. This "Wide Beam" technology offers nearly double the coverage under your boat, making it significantly easier to locate fish in the upper water column and producing the large, clear fish arches that every skipper looks for.

At Morgan Marine, we recommend this 0° version specifically for vessels with a flat or near-flat hull (0° to 7° deadrise). Because the ceramic element is fixed at 0° within the low-profile bronze housing, the beam is oriented perfectly vertically, ensuring maximum echo returns and the most accurate depth and temperature data possible.

The B175H-W operates across the 150–250 kHz frequency band. While standard high-frequency transducers focus on a tight area to find deep-water targets, the "High-Wide" is the specialist's choice for inshore and pelagic fishing. It delivers the perfect balance of ultra-high resolution and massive coverage, essential for tracking baitfish and schooling gamefish down to depths of 152m (500ft)

Raymarine B175H-W 1000W D/T Through Hull Wide Beam Transducer Key Features

• Massive 1kW Power: High-performance 1000W output provides exceptional target separation and clarity, even at higher cruising speeds.
• Constant 25° Wide Beam: Offers double the coverage of standard narrow-beam transducers. Spend less time searching and more time with lines in the water.
• High-Frequency CHIRP (150–250 kHz): Exceptional detail for identifying individual fish targets and fine bottom structures.
• 0° Tilted Element: Purpose-built for hulls with a deadrise of 0° to 7°. No fairing block is required, resulting in a flush, low-drag installation.
• Integrated Sensors: Provides high-accuracy Depth and fast-response Water Temperature (D/T) data directly to your Raymarine display.
• Low-Profile Bronze Housing: Engineered for durability in harsh marine environments. The low-profile design minimises turbulence, ensuring clean sonar imagery at speed.
• Fishing Versatility: The ideal choice for coastal fishing, offshore trolling, and identifying fish tight to wrecks and reefs.

Technical Specifications:

Morgan Marine Expert Tip: When installing the B175H-W as a single transducer, ensure you have the correct Raymarine adapter cable (A80328) for your specific MFD or sonar module.

Raymarine B175H-W 1000W D/T Through Hull Wide Beam Transducer FAQs

What makes the ‘Wide Beam’ version different from the standard B175H?

The ‘W’ stands for Wide. While a standard high-frequency transducer has a narrow beam (often around 6° to 10°), the B175H-W provides a constant 25° beam angle across the entire frequency band. This gives you roughly double the coverage under the boat, making it far easier to spot fish in the upper water column and producing those large, clear fish arches that every angler looks for.

Why should I choose the 0° Angle version?

Transducer "tilt" is designed to compensate for the deadrise (the V-shape) of your hull. The 0° model is specifically for boats with a flat or nearly flat bottom, where the hull deadrise is between 0° and 7°.

Note: If your hull has a steeper deadrise (8° to 24°), you will need the 12° or 20° tilted versions to ensure the sonar beam points straight down at the seabed.

What depths can I expect to reach with this 1kW transducer?

The B175H-W is designed for high-resolution performance in shallower to mid-depth waters. You can expect excellent results down to approximately 150 metres (500 feet). Because it uses High-Wide CHIRP (150-250 kHz), it excels at target separation near the surface and mid-water rather than extreme deep-sea floor tracking.

Is my hull material compatible with a bronze housing?

This transducer features a bronze housing, which is ideal for fibreglass and wood hulls.

Warning: Do not install a bronze transducer in an aluminium or steel hull, as this will cause galvanic corrosion which can damage your vessel. For metal hulls, please contact us for the Stainless Steel (SS175HW) equivalent.

Which Raymarine sonar modules is this compatible with?

The B175H-W is a premium CHIRP transducer. It is directly compatible with Raymarine’s CP470 and CP570 sonar modules. It can also be used with the Axiom Pro RVX and Axiom 2 Pro RVM series, as well as the RVX1000 module.

Do I need any additional cables for installation?

Yes, depending on your setup: If you are connecting this as a single transducer to a CP470/CP570 or Axiom Pro, you will typically require the A80328 single transducer adapter cable. If you are pairing it with another B175 (like a Low-frequency model), a Y-cable (A102146) may be required.

Can I use this transducer at high speeds?

Yes. Because the B175H-W is a flush-mount, low-profile transducer, it creates very little drag. When installed in a location with "clean" water (free from turbulence and bubbles), it provides excellent sonar readings even when the boat is on the plane and travelling at high speeds.

Does it measure water temperature?

Absolutely. This unit features a built-in, fast-response water temperature sensor, providing highly accurate readings to your Raymarine display—vital for finding the "edges" where fish like to feed.

How big is the hole I need to drill?

For a standard installation in a wood or fibreglass hull, you will need a 95mm (3-3/4") hole saw. We always recommend professional installation to ensure the hull is properly sealed and the transducer is correctly aligned with the keel.
