Upgrade your marine electronics setup with the Furuno 165T/275LHW-12P, a versatile pocket mount combo transducer designed specifically for anglers and boaters who demand precise underwater imaging. This innovative unit blends advanced 3D sonar capabilities with wideband CHIRP technology, delivering crystal-clear visuals of fish, structure, and bottom contours even in challenging conditions. Whether you're chasing trophy fish in deep water or navigating shallow bays, this transducer elevates your situational awareness on the water.

Key Features That Set It Apart

Crafted with a compact new housing measuring roughly 12 inches long, 5 inches wide, and 3.5 inches high, the 165T/275LHW-12P fits seamlessly into pocket-style mounts without compromising performance. Here's what makes it a standout choice:

• 165 kHz DFF3D Frequency: Powers Furuno's DFF3D sonar for stunning 3D imaging, showing fish arches in three dimensions and revealing bottom hardness variations for better bait placement.
• Low CHIRP (42-65 kHz): Offers dynamic beamwidth from 25° to 16°, ideal for scanning wide areas in deeper waters up to hundreds of feet, picking up bait schools and wrecks with exceptional target separation.
• High CHIRP (150-250 kHz): Maintains a consistent 25° beamwidth for sharp, detailed images in mid-to-shallow depths, perfect for structure fishing around reefs or drop-offs.
• 12-Meter Cable: Provides ample length for flexible routing during installation, reducing signal loss and ensuring reliable connectivity.
• Integrated Motion Sensor: Automatically stabilizes sonar readings against boat roll and pitch, delivering steady images no matter the sea state.
• Built-in Temperature Sensor: Tracks water temp changes in real-time, helping you locate thermoclines where fish congregate.

Superior Performance for Real-World Fishing

Imagine scanning a 3D slice of the water column, spotting a school of snapper hovering 20 feet off a rocky ledge— that's the power of combining DFF3D with CHIRP in one unit. Unlike traditional single-frequency transducers, the dual-band CHIRP sweeps across frequencies for noise rejection and finer detail, cutting through thermoclines and muddy bottoms. Boaters report fewer false readings and more hookups thanks to the enhanced vertical resolution, which can distinguish individual fish in tight pods. In pocket mount installations, it hugs the hull for minimal drag and protected operation, thriving on planing hulls from center consoles to sportfishers.

Installation Insights for Seamless Integration

Pocket mounting positions the transducer flush or nearly flush with the hull, optimizing signal transmission while shielding it from debris and cavitation. Pair it with Furuno's TZT3 multifunction displays for plug-and-play compatibility—simply connect to the DFF3D module, and you're ready to layer 3D sonar over charts and radar. Pro tip: Fair the mount carefully with marine epoxy to eliminate air pockets, ensuring bubble-free transmission at speed. The included motion sensor self-calibrates, so no manual adjustments needed post-install.

Why It Excels in Diverse Conditions

From offshore bluewater hunts to inshore flats fishing, this transducer adapts effortlessly. The low CHIRP punches deep for swordfish runs, while high CHIRP excels at marking stripers nearshore. Furuno's rugged construction withstands constant saltwater exposure, vibration, and impacts, backed by marine-grade materials that resist fouling. Anglers love how it reveals bottom composition—soft mud vs. hard rock—for smarter jigging and trolling decisions.

Equip your vessel with technology that turns guesses into precision—perfect for serious offshore adventures or everyday angling success.
