B75M BB TH profils 0°

The B75M transducer stands out with its mid-frequency CHIRP technology, offering an excellent compromise for versatile use in coastal and moderate offshore waters. Unlike low-frequency transducers (B75L) for deep waters or high-frequency ones (B75H) for detailed shallow-water imaging, the B75M is designed for broader coverage. Its 0° profiling is specifically suited to hulls with low deadrise or locations where the hull angle is zero, ensuring optimized hydrodynamic performance.

CHIRP (Compressed High-Intensity Radiated Pulse) technology sends a frequency sweep across a wide band instead of a single fixed frequency. This results in better target separation, superior image clarity, and more precise detection of fish and underwater structures compared to traditional fishfinders.

The RAYMARINE B75M BB TH thru-hull transducer (0°) is designed to deliver accurate depth and water temperature data to compatible Raymarine navigation systems.

"Profilée 0 deg" indicates that the transducer is designed to be installed on hulls with a deadrise angle (hull angle relative to horizontal) of 0 degrees, or in locations where the mounting surface is perfectly flat. This ensures the transducer is parallel to the water surface, maximizing signal quality and hydrodynamic performance.

The B75M transducer, with its CHIRP mid-frequency technology, is an ideal compromise for versatile use. It is suitable for both coastal waters and moderate offshore waters, delivering good performance across a range of depths.

A through-hull transducer (TH) such as the B75M BB TH offers several advantages. It is mounted directly through the hull, which significantly reduces turbulence around the sensor and maximizes signal quality. This is essential for obtaining reliable readings at high speeds and in rough seas, providing superior performance compared to transom-mount transducers.

No, this transducer is specifically designed to provide depth and temperature data. It does not transmit speed data.

The RAYMARINE B75M BB TH 0° angled black-box transducer is designed to connect to Raymarine CHIRP-compatible fishfinder modules. It is compatible with modules such as the CP370, CP470, and CP570.

No, this is a black-box-style transducer (BB). It comes with bare wires and must be connected to a compatible Raymarine CHIRP sounder module (such as the CP370, CP470, CP570), which will then connect to your multifunction display.

The RAYMARINE B75M BB TH 0° fairing CHIRP transducer is specifically designed for Raymarine’s sounder ecosystem and its CHIRP modules. Compatibility with other brands’ equipment is not guaranteed and generally not recommended.

No, the A80017 transducer is a CHIRP mid-frequency transducer. It requires a compatible Raymarine CHIRP sounder module to operate correctly. It is not compatible with traditional fixed-frequency sounder systems.

The RAYMARINE B75M BB TH faired 0° transducer is a "black box" (BB) type transducer, meaning it is supplied with bare wires for direct and custom connection to a compatible RAYMARINE CHIRP fishfinder module. It does not come with a ready-to-use connector.

This transducer is specifically designed for through-hull (TH) installation on hulls with low deadrise or locations where the hull angle is 0 degrees. It is ideal for boats with relatively flat mounting surfaces.

Yes, as this is a through-hull transducer (TH - Through-Hull), installation requires drilling a hole in the boat's hull to insert the transducer body. This ensures direct exposure to water and optimal performance.

Installing a through-hull transducer like the B75M BB TH requires drilling the hull and ensuring perfect watertightness. While an experienced sailor may be able to do it, it is strongly recommended to hire a qualified professional to guarantee a correct and secure installation, avoiding any risk of water ingress.

The term "profilée 0 deg" means the depth sounder itself is designed for a 0-degree angle. During installation, it is critical to select a hull location where the deadrise angle is closest to 0 degrees, or to use a fairing block to compensate for the hull angle and ensure the transducer face is perfectly parallel to the water surface.

The exact diameter of the hole to drill depends on the precise model and the installation specifications provided by Raymarine. It is imperative to consult the official installation manual for product A80017 to obtain this critical information and avoid any errors.

Yes, location is critical. The depth sounder must be installed in an area of the hull where water flow is most laminar and free of air bubbles, away from propellers, keels, water intakes, or any other disturbances. A good location minimizes turbulence and maximizes signal quality for accurate readings.

For installation, you will typically need a drill with an appropriate hole saw (check the manual for diameter), marine sealants (caulk), sandpaper, surface cleaner, and potentially clamping tools. The specific tools and exact materials are detailed in the installation guide provided by Raymarine.

Waterproofing is ensured by using specific marine sealants and gaskets provided or recommended by the manufacturer. During installation, the transducer body is inserted into the drilled hole, and sealants are applied generously between the transducer and the hull, as well as around the fastenings, to prevent water ingress. It is essential to strictly follow the installation manual instructions.
