B75M BB TH-profilozott 12°-os

This is a through-hull bronze transducer designed for boats, using CHIRP mid-band (M) technology for precise bottom detection and improved target separation. Its 12-degree tilted element is ideal for hulls with a deadrise angle of 8 to 15 degrees.

The 'M' indicates that the transducer operates on a medium-frequency band (Medium CHIRP), typically between 80 and 130 kHz. This provides a good balance between deep penetration and detail resolution for various fishing and navigation applications.

CHIRP technology sends a frequency sweep over a wide band rather than a single fixed frequency. This results in superior image resolution, better target separation (fish, structures), and more reliable detection at different depths, providing a clearer and more detailed image of the seabed.

Thanks to its mid-frequency band, the B75M transducer is versatile and suitable for a variety of fishing, including inshore and moderate offshore fishing. It provides a good balance for detecting fish and seabed structures at mid-range depths.

The Raymarine B75M transducer has a power output of 600 watts (RMS).

The maximum detection depth depends on water conditions (salinity, temperature, clarity) and the depth sounder system it is connected to. However, the B75M is generally effective for depths up to approximately 250 meters (800 feet) under optimal conditions.

The beam angle of the B75M transducer is variable across its mid-frequency range. It is typically around 16-24 degrees at 80 kHz and 11-16 degrees at 130 kHz, providing coverage suited to different depths.

The Raymarine B75M BB TH profiled 12° (A80034) transducer is made of bronze, a durable and corrosion-resistant material, ideal for marine environments.

No, this bronze transducer is not recommended for aluminum or steel hulls due to the risk of galvanic corrosion. It is specifically designed for fiberglass or wooden hulls.

Yes, the B75M transducer is designed to operate effectively in both freshwater and saltwater, providing reliable performance in various marine environments.

'THprofilée' means through-hull profiled. The transducer element is tilted at 12 degrees inside the housing. This compensates for the hull's deadrise angle, ensuring the sonar beam is directed vertically downward without requiring an external fairing block.

This transducer is specifically designed for fiberglass hulls with a deadrise angle between 8 and 15 degrees. The internal 12-degree tilt of the element corrects this angle.

No, one of the main advantages of this 'faired' transducer is that it already incorporates the 12-degree correction angle. It is designed to be installed directly on the hull without requiring an external fairing shoe, which reduces drag and simplifies installation.

Installing a through-hull transducer requires drilling a hole in the hull and meticulous sealing. While an experienced sailor may perform this task, it is highly recommended to hire a qualified professional to ensure a correct and watertight installation, thereby avoiding any risk of leakage.

The transducer must be installed in an area free of water turbulence, away from propellers, keels, other transducers, or any other obstruction that could disrupt the sonar beam. Ideally, it should be placed in the forward third of the hull, on a flat and smooth surface.

No, the B75M transducer is a CHIRP transducer and requires a compatible CHIRP sounder module or multifunction display to operate correctly. It will not work with traditional single-frequency sounders.

Yes, the Raymarine B75M BB TH profiled 12° transducer benefits from Raymarine's standard manufacturer warranty.
