AI-165T/265LH-PM488-12P - Combined DFF3D and CHIRP Thru-Hull Transducer

The Airmar AI-165T/265LH-PM488-12P transducer is a compact through-hull urethane model combining DFF3D multibeam sonar functionality with traditional CHIRP frequencies. It is designed to provide detailed underwater visualization and precise target detection for advanced navigation systems.

This transducer operates on multiple frequencies:

For the DFF3D multibeam sonar: 165 kHz. For the low-frequency CHIRP: from 42 kHz to 65 kHz. For the high-frequency CHIRP: from 130 kHz to 210 kHz.

The maximum depth reached by this transducer varies depending on the frequency used:

For low frequencies (CHIRP): up to 914 metres.For high frequencies (CHIRP): up to 304 metres.

The Airmar AI-165T/265LH-PM488-12P transducer integrates two essential sensors:

A motion sensor. A water temperature sensor.

For the DFF3D function, the transducer provides a 120° lateral beam width, enabling extended seafloor coverage.

CHIRP beam widths vary depending on the frequency range:

For low frequencies (42–65 kHz): beam width ranges from 25° to 16°. For high frequencies (130–210 kHz): beam width ranges from 10° to 6°.

The Airmar AI-165T/265LH-PM488-12P transducer housing is made of urethane, a robust and durable material optimized for through-hull installations.

Yes, this transducer supports bottom discrimination (Bottom Discrimination) when used with the Furuno DFF1-UHD module, without TID.

Yes, this transducer is optimized for a "pocket mount" installation and is suitable for high-speed vessels as well as fiberglass hulls.

The transducer is supplied with a 12-metre cable.

Yes, the Airmar AI-165T/265LH-PM488-12P transducer supports Accu-fish functions when used with the Furuno DFF1-UHD module, without TID, enabling accurate fish detection.

This transducer uses combined technology, integrating a DFF3D multibeam sonar for 3D visualization and side-scan capabilities, as well as traditional CHIRP frequencies for target discrimination and extended coverage.

This transducer is compatible with the Furuno DFF3D multibeam sonar module. It is also recommended for installations using the DFF1-UHD module.

The transducer is compatible with Furuno TZTouch3 displays, including models TZT12f, TZT16F, and TZT19F.

Yes, this transducer is recommended for DFF1-UHD installations and supports specific functions such as bottom discrimination and Accu-fish when used with this module (without TID).

The 12 m cable supplied with the transducer includes:

A "pigtail" cable for DFF1-UHD. A 7-pin connector. A 12-pin connector for DFF3D/TZTouch3.

The Airmar AI-165T/265LH-PM488-12P transducer is specifically designed and optimized for integration with Furuno systems, such as the DFF3D multibeam sonar module, TZTouch3 displays, and the DFF1-UHD module. Compatibility with other brands is not stated and cannot be guaranteed.

This transducer is a through-hull model, specifically designed for a pocket-mount installation.

Yes, installing this "pocket mount" depth sounder requires hull modification for proper integration.
