Raymarine B175L Bronze Low Profile 1000W D/T Through Hull Transducer 0° Angle

Raymarine B175L Bronze Low Profile 1000W D/T Through Hull Transducer 0° Angle

Raymarine B175L Bronze Low Profile 1000W D/T Through Hull Transducer 0° Angle are for the serious offshore angler and coastal explorer, the Raymarine B175L is the ultimate low-frequency CHIRP solution. Designed for high-speed performance and exceptional depth, this 1kW "Low-Profile" transducer sits nearly flush to your hull, reducing drag and improving water flow to provide crystal-clear readings even when you're on the plane.

This specific 0° Tilted Element model is engineered for boats with a hull deadrise of 0° to 7°. Because the ceramic element is fixed at a 0° angle inside the housing, it ensures the sonar beam is aimed straight down at the seabed, providing the most accurate depth readings and maximum signal return for hulls with little to no deadrise.

Whether you are hunting for deep-water species or navigating challenging coastal channels, the Low CHIRP frequency (40-60 kHz) provides the "punch" needed to see through the water column down to depths of 2,500ft (762m).

Raymarine B175L Bronze Low Profile 1000W D/T Through Hull Transducer 0° Angle  Key Features

• 1000W High-Power Output: Delivers incredible deep-water performance and superior target separation compared to standard 600W units.
• Low-Frequency CHIRP: Operates across the 40-60 kHz band with a total bandwidth of 20 kHz, making it the "deep water performer" of the B175 range.
• 0° Tilted Element: Specifically designed for hulls with a deadrise angle between 0° and 7°, ensuring the sonar beam is perfectly vertical.
• Low-Profile Design: Minimises drag and provides excellent display resolution at high speeds; ideal for stepped, planing, or displacement hulls.
• Bronze Housing: Robust construction suitable for both fibreglass and wood hulls.
• Depth & Temperature: Includes a fast-response water temperature sensor for accurate real-time data.
• Maximum Depth: Capable of reaching depths up to 2,500ft (762m) depending on water conditions.
• Broad Beamwidth: Features a 32° to 21° beamwidth, providing wide coverage for tracking baitfish and identifying bottom structures.

Raymarine B175L Bronze Low Profile 1000W D/T Through Hull Transducer 0° Angle FAQs

What does the "0° Angle" or "0° Tilt" actually mean?

The B175L is a "Tilted Element" transducer. While the bronze housing sits flush against your hull, the internal ceramic element is fixed at a specific angle to counteract the "deadrise" (the V-shape) of your boat’s hull. The 0° model is designed for hulls with a deadrise between 0° and 7°. * If your hull is nearly flat at the mounting point, this is the version you need to ensure the sonar beam points straight down at the seabed.

Why should I choose the "L" (Low) frequency version over Medium or High?

The "L" stands for Low CHIRP (40kHz to 60kHz). This frequency is the specialist for deep-water performance. It provides a wider beam (32° to 21°) which is excellent for:

Tracking the bottom at great depths (up to 762m / 2,500ft).

Searching for large targets in a wider area of the water column.

Maintaining a clear signal at higher cruising speeds.

Is my boat's hull material compatible with a Bronze transducer?

This bronze housing is specifically designed for Fiberglass or Wood hulls.

Important: Never install a bronze transducer in a metal (aluminium or steel) hull, as this will cause galvanic corrosion which can damage your hull. For metal boats, please ask us about the Stainless Steel (SS175) equivalents.

What Raymarine equipment is this compatible with?

The B175L is a 1kW CHIRP-ready transducer. It is compatible with Raymarine’s professional-grade sonar modules, including the CP470 and CP570. It can also be connected to various Axiom displays, though depending on your setup, you may require a specific adapter cable (e.g., the A80328 for single operation).

Not sure about your specific MFD?

Give our team a call and we’ll check the exact cable requirements for you.

Does it provide water temperature as well as depth?

Yes. The B175L is a D/T (Depth and Temperature) unit. It features a fast-response water temperature sensor, giving you accurate readings—essential for finding those temperature breaks where fish like to congregate.

Can I use this alongside another B175 transducer?

Absolutely. Many of our customers "pair" this Low frequency unit with a Medium (B175M) or High (B175H) version to get the best of both worlds. To do this, you will typically use a Y-cable (A102146) to feed both signals into your sonar module.

Will this transducer affect my boat's performance on the trailer?

One of the best features of the B175 series is its Low Profile design. Because it sits almost flush to the hull (protruding less than 6mm), it does not require a bulky fairing block. This means it won't interfere with your trailer rollers or bunks, making it the ideal choice for trailerable boats.

What size hole needs to be cut for installation?

For a standard fiberglass or wood hull, you will need a 95mm (3.75") hole saw. As always, we recommend professional installation for through-hull fittings to ensure a watertight seal and optimal orientation (the arrow on the transducer must always point toward the keel).
