Discover the power of advanced underwater imaging with the Furuno 165T/265LH-PM488, a game-changing combo transducer designed for serious boaters and anglers who demand precision on the water. Combining DFF3D technology for stunning 3D sonar visuals with wideband CHIRP capabilities, this pocket-mount unit delivers unmatched clarity, whether you're chasing trophy fish in deep waters or mapping intricate bottom structures. Its robust in-hull design ensures seamless integration without compromising hull integrity, making it a favorite for both recreational cruisers and professional charters.

Why This Transducer Stands Out on the Water

Imagine slicing through murky depths to reveal fish schools in vivid detail, track bait balls with pinpoint accuracy, and even discriminate bottom types—all from a single, streamlined housing. The Furuno 165T/265LH-PM488 excels in real-world conditions, thanks to its built-in motion sensor that stabilizes images during choppy seas and a temperature sensor for spotting thermoclines where big game lurks. Unlike basic transducers, its dual-frequency setup covers vast low-CHIRP sweeps for wide-area coverage and focused high-CHIRP for narrow, high-resolution targeting, adapting to your fishing style effortlessly.

Superior Performance Specs Tailored for Marine Pros

• Powerhouse Output: Rated at 1000 watts, it punches through water columns up to extreme depths, ideal for offshore adventures.
• Versatile Frequencies: Low CHIRP (42-65 kHz) with expansive 25° to 16° beamwidth for bottom scanning; High CHIRP (130-210 kHz) narrowing to 10° to 6° for precise fish ID; plus 165 kHz dedicated DFF3D for immersive 3D mapping.
• Smart Sensors: Integrated motion and temperature sensors provide stabilized views and environmental data to refine your strategy.
• Durable Build: Housed in a compact Airmar PM488 pocket-mount enclosure (roughly 12" long, 5" wide, 3.5" high), it's engineered for reliable in-hull performance with a generous 39-foot cable for flexible routing.
• Connection Ready: Features a 7-pin setup with pigtails for easy pairing with DFF3D and DFF1-UHD sounders, plus Accu-Fish and bottom discrimination modes.

Real-World Benefits for Every Boater

For weekend warriors, it transforms routine trips into thrilling hunts by highlighting structure and fish in ways standard 2D sonar can't match. Commercial operators appreciate the reduced noise floor and enhanced discrimination, saving fuel and time on long hauls. The pocket-mount installation minimizes drag and maintenance hassles compared to thru-hull alternatives, while the 120° forward-facing DFF3D view lets you "see ahead" of your boat—perfect for navigating reefs or spotting wrecks proactively.

Users rave about its ability to separate fish from clutter in heavy cover, with the motion sensor ensuring rock-solid 3D layers even at trolling speeds or in swells. Pair it with Furuno's ecosystem for seamless data overlays on multifunction displays, elevating your on-water decision-making.

Installation Insights for Smooth Setup

Fitting this transducer calls for a pre-molded pocket in fiberglass hulls (deadrise up to 25° works best), ensuring optimal acoustic coupling with non-air-entraining potting compounds. Its 12-meter cables simplify wiring to nav stations, and the pigtail design speeds up connections. Always match your sounder's power to unlock full potential—think high-end Furuno black box processors for pro-level results. Pro tip: Calibrate the motion sensor post-install for drift-free imaging.

Perfect Match for Modern Fishfinding Systems

Engineered specifically for DFF3D and DFF1-UHD combos, it unlocks features like forward-facing 3D sonar, fish size estimation, and bottom hardness mapping. Compatible with a range of Furuno MFDs, it future-proofs your setup for software updates that keep pace with evolving marine tech.

Equip your vessel with this transducer to unlock deeper insights and bigger catches—precision engineering that redefines what's possible beneath the surface.
