Key Features of the Furuno 165T 275LHW transducer
- Dual frequency operation: 165 kHz and 275 kHz for versatile sonar imaging
- Wide beam design to maximize underwater coverage area
- Compact pocket mount housing for streamlined installation and protection
- Compatible exclusively with Furuno DFF3D sonar systems
- Durable construction suited for saltwater and freshwater conditions
How the Furuno 165T 275LHW transducer works
The transducer emits sonar pulses at two frequencies, 165 kHz for broad coverage and 275 kHz for higher resolution imaging. These pulses bounce off underwater objects and return to the transducer, which processes the signals to generate detailed 3D images of fish, structures, and the seabed.
Its wide beam angle means that the sonar cone covers a larger volume of water, improving target acquisition and reducing blind spots, essential for efficient fishing and safe navigation.
Why choose a pocket mount combo transducer?
Unlike traditional transducers mounted directly on the hull, the pocket mount design of the Furuno 165T/275LHW places the unit inside a hydrodynamic recess or “pocket” built into the hull. This reduces drag and the risk of damage from debris or impacts.
This design also helps to maintain consistent signal quality, even at higher speeds, making it a favored choice for many boat owners who value performance and longevity.
Installation Guide for Furuno 165T 275LHW transducer
Proper installation of the Furuno 165T/275LHW transducer is critical to ensuring optimal performance. The pocket mount transducer requires precise hull modification to accommodate the mounting pocket.
Professional installation is recommended, but here are the essential steps:
- Determine the ideal hull location below the waterline free from turbulence and bubbles.
- Cut and prepare a pocket in the hull according to Furuno’s specifications.
- Seal and secure the transducer in the pocket with marine-grade epoxy or sealant.
- Route the cable to the DFF3D sonar unit avoiding sharp bends and interference.
- Test the unit in water to verify signal strength and image clarity before finalizing the installation.
Maintenance Tips for Furuno 165T 275LHW transducer
Maintaining the Furuno 165T/275LHW transducer is essential to prolong its service life and ensure consistent performance.
Regular inspection and cleaning of the transducer face are necessary, especially after exposure to saltwater environments where marine growth can accumulate.
- Clean the transducer with fresh water and a soft cloth after every use.
- Inspect the mounting pocket for leaks or damage periodically.
- Check the cable and connector for corrosion or wear.
- Schedule professional servicing at least annually or when performance issues arise.
Avoid using abrasive materials or harsh chemicals that may damage the transducer surface.
Expert Advice and Pro Recommendations
Experts recommend pairing the Furuno 165T/275LHW transducer with the Furuno DFF3D system for best results, as these components are engineered to work seamlessly together.
For anglers seeking maximum detail in fish detection, tuning the sonar settings to the 275 kHz frequency provides higher resolution imaging, while the 165 kHz frequency offers broader area scanning ideal for locating schools of fish.

Understanding Sonar Frequencies and Beam Angles
Choosing the right sonar frequency and beam angle is crucial for effective underwater scanning. The Furuno 165T/275LHW transducer’s dual frequencies serve different purposes:
- 165 kHz: Lower frequency with wider beam angle, ideal for deep water scanning and broad coverage.
- 275 kHz: Higher frequency with narrower beam angle, providing detailed, high-resolution images close to the boat.
The wide beam angle enhances target separation and bottom detail, which is vital for fishing in diverse marine environments.

Troubleshooting Common Furuno 165T 275LHW transducer Issues
While the Furuno 165T/275LHW transducer is robust, users occasionally encounter issues such as weak sonar returns, erratic readings, or no signal. Common causes include cable damage, improper installation, or fouling.
To troubleshoot:
- Check all cable connections for secure and corrosion-free contacts.
- Clean the transducer face of any debris or growth.
- Verify the transducer alignment and mounting pocket integrity.
- Test the unit on a different boat or hull surface if possible.
Consistent maintenance and professional inspections help prevent these problems.
Detailed FAQ Section
What makes the Furuno 165T/275LHW transducer different from other transducers?
The Furuno 165T/275LHW transducer stands out due to its combination of dual frequency operation and pocket mount design. Unlike traditional transducers that may be mounted externally on the hull, this model fits into a recessed pocket, significantly reducing drag and risk of damage. It offers wide beam sonar coverage at both 165 kHz and 275 kHz frequencies, delivering versatile scanning for both broad-area searching and detailed imaging. This unique combination makes it especially effective for use with the Furuno DFF3D sonar system, providing users with clearer, more detailed underwater images and better fishfinding capabilities.
