Raymarine B175H Bronze Low Profile 1000W D/T Through Hull Transducer 0° Angle

Raymarine B175H Bronze Low Profile 1000W D/T Through Hull Transducer 0° Angle

Raymarine B175H Bronze Low Profile 1000W D/T Through-Hull Transducer (0° Angle)
is a 1kW CHIRP-ready transducer is the ideal choice for serious anglers and boaters seeking superior target separation and high-resolution detail in shallower waters.

Constructed from premium marine-grade bronze, the B175H features a low-profile housing that sits almost flush to your hull. This streamlined design reduces drag and ensures clean, turbulent-free water flow across the sensor face, providing clear sonar imagery even at high cruising speeds. As a High-Frequency specialist, this transducer excels at pinpointing fish holding tight to wrecks, reefs, and bottom structures, while providing incredible clarity for schooling baitfish.

This specific 0° Angle model is engineered for vessels with a hull deadrise between 0° and 7°. Because the ceramic element is fixed at 0° within the housing, there is no need for a bulky fairing block, allowing for a neat, "low-profile" installation that doesn't compromise your boat’s performance.

Morgan Marine Expert Tip: The B175H is a "single-band" transducer. If you are connecting this as your only transducer, you will require the Raymarine single-operation cable (A80328). If you are pairing it with another B175 unit (e.g., a Low-frequency model) for a dual-band setup, please contact us for advice on the correct Y-cable.

Raymarine B175H Bronze Low Profile 1000W D/T Through Hull Transducer 0° Angle Key Features

• Powerful 1kW Performance: The 1000W output provides exceptional depth penetration and allows your CHIRP sonar to "see" through the water column with 5 to 10 times the detail of standard transducers.
• High-Frequency CHIRP (130–210 kHz): Perfect for shallow to mid-depth fishing. This frequency band offers a narrow, concentrated beam (9° to 15°) that provides crisp target separation of individual fish.
  
• 0° Tilted Element: Purpose-built for hulls with a deadrise of 0° to 7°. The internal ceramic is factory-set to ensure the beam points straight down, compensating for your hull's shape without needing a fairing block.
• Integrated D/T Sensors: Provides highly accurate Depth and fast-response Water Temperature data directly to your Raymarine MFD.
• Low-Profile Bronze Housing: Rugged, durable, and designed to withstand harsh saltwater environments. The low-drag design ensures the transducer remains effective even when you're on the plane.
• Maximum Depth: Capable of reaching depths up to 304m (1,000ft) depending on water conditions.
• Hull Compatibility: Suitable for installation in fibreglass and wood hulls (not for use in metal hulls).

Raymarine B175H Bronze Low Profile 1000W D/T Through Hull Transducer 0° Angle FAQs

What does the ‘0° Angle’ actually mean?

This refers to the "Tilted Element" inside the bronze housing. In a 0° model, the ceramic element is fixed perfectly horizontal. This version is designed specifically for boats with a flat or nearly flat hull—specifically those with a deadrise angle between 0° and 7°.

If your hull has a steeper V-shape (8° to 24°), you would need the 12° or 20° tilted versions instead to ensure the sonar beam points straight down to the seabed.

Why should I choose the ‘High’ (H) frequency over others?

The ‘H’ stands for High Frequency (130-210 kHz). This is the gold standard for target separation. If you are looking to distinguish individual fish within a tight school or want to see fish holding very close to wrecks and reefs, the narrower beam of the B175H provides the crisp detail you need.

What is the maximum depth I can expect?

With a powerful 1000W (1kW) output, the B175H is a high-performer. You can typically expect clear bottom tracking and fish detection down to approximately 300 metres (1,000 feet), depending on water conditions.

Is this transducer compatible with my boat’s hull material?

This is a Bronze transducer, which is designed for use on fibreglass or wood hulls.

Crucial Tip: Never install a bronze transducer in an aluminium or steel hull, as this will cause galvanic corrosion and damage your hull. For metal boats, please ask us about the Stainless Steel (SS175) equivalent.

What is the advantage of the ‘Low Profile’ design?

Unlike traditional "block" transducers that require a large fairing block, the B175H sits nearly flush with your hull (extending only about 6mm). This creates significantly less drag and turbulence, meaning you get much clearer sonar readings while travelling at higher speeds.

Will I need any extra cables to get it working?

The B175H usually comes with a 10-metre cable. However, depending on your setup:

• • Single Transducer: If you are connecting this as your only transducer to a CP470/CP570 or an Axiom Pro/XL, you will typically need the A80328 single operation cable.
  • Pairing: If you are running this alongside a Low or Medium frequency B175 to get a full range of depths, you’ll need a Y-cable (A102146) to join them into one sonar port.

Does it provide water temperature?

Yes, the B175H features a fast-response internal thermistor that provides highly accurate sea surface temperature readings directly to your Raymarine display.

Can I install this myself?

While it is possible for a confident DIYer, it does require cutting a 95mm (3-3/4") hole in your hull. It also must be bedded correctly with marine sealant (like 3M 5200) and aligned so the internal arrow points toward your keel. If you’re unsure, we always recommend professional installation to protect your hull’s integrity.

Still have questions?
