Furuno B265LH Bronze Thru-Hull CHIRP Transducer - 12-Pin Product Description
Unlock Superior Underwater Visibility with CHIRP Technology
Imagine gliding through open waters, your fish finder painting a crystal-clear picture of what's below—schools of fish separated from structure, bottom details sharper than ever. That's the power of the Furuno B265LH Bronze Thru-Hull CHIRP Transducer. Unlike older sonar systems stuck on fixed frequencies like 50 kHz or 200 kHz with short pulses and narrowband elements, this transducer sweeps across a broad spectrum in a single long pulse. The result? Sound energy up to 1,000 times stronger hitting the water, echoes bouncing back richer and more detailed, all processed through advanced digital signal tech for unmatched fish and bottom detection.
Crafted from durable bronze, this thru-hull design mounts flush for minimal drag, perfect for high-speed boating. It includes a high-speed fairing block to streamline installation and performance, ensuring you capture every sonar return without interference.
Key Specifications That Deliver Pro-Level Performance
Built for serious anglers and mariners, the B265LH packs specs that handle deep water and demanding conditions:
- Mounting: Thru-hull for clean, low-profile installation
- Connector: 12-pin for seamless integration
- Max Depth: Rated to 3,000 feet—ideal for offshore adventures
- Power Handling: 1,000 watts to push signals far and strong
- CHIRP Bands: Low: 42-65 kHz (wide coverage for deep water), High: 130-210 kHz (sharp detail for shallower targets)
- Beam Angles: 25° x 16° at low freq / 10° x 6° at high freq for versatile scanning
- Cable: 39.3 feet of rugged length for flexible routing
These aren't just numbers—they translate to spotting bait balls at depth, distinguishing wrecks from reefs, and marking individual fish in thick schools.
Why CHIRP Outshines Traditional Sonar Every Time
Switching to CHIRP means ditching the limitations of conventional fish finders. Traditional setups blast short, single-frequency pulses that blur targets and miss subtle bottom changes. The B265LH's broadband sweep captures more data per ping, delivering:
- Exceptional target separation—see fish as distinct arches, not blobs
- Enhanced bottom discrimination—spot hard rock from soft mud
- Thermocline detection for finding temperature breaks where fish hide
- Noise rejection in choppy seas or around props
Pair it with Furuno's ecosystem, and digital processing sharpens images further, giving you an edge whether trolling for tuna or jigging snapper.
Real-World Advantages for Boaters and Anglers
Bronze construction laughs off saltwater corrosion, holding up season after season. The thru-hull mount shines at speed, with the included fairing optimizing flow to cut turbulence and boost accuracy. Think of it as your boat's underwater eyes, refined for everything from coastal cruising to bluewater expeditions.
Users rave about how it transforms murky returns into actionable intel—pinpointing structure edges or tracking bait movement. Backed by a solid 3-year warranty, it's a reliable upgrade that pays off in bigger catches and safer navigation.
Pro tip: Position it forward and slightly off-center to avoid hull wakes, maximizing clean pings from hull deadrise up to 24 degrees.
Frequently Asked Questions
What makes the Furuno B265LH better than standard transducers?
Its CHIRP technology sweeps multiple frequencies for vastly more detail and energy than fixed-frequency sonars, revealing finer fish separation and bottom features.
Is the B265LH suitable for deep-water fishing?
Yes, with a 3,000-foot depth rating and 1,000-watt power, it excels in offshore scenarios, using low CHIRP for deep penetration.
Does it include everything needed for installation?
It comes with a high-speed fairing block and 39.3 feet of cable, ready for thru-hull mounting on most fiberglass or wood hulls.
What frequencies does the low and high CHIRP cover?
Low band: 42-65 kHz for broad, deep coverage; high band: 130-210 kHz for precise, shallow-water imaging.
Can this transducer handle high boat speeds?
Absolutely—the bronze thru-hull design with fairing block minimizes drag, maintaining clear sonar at planing speeds.
What's the beamwidth for scanning?
25° x 16° on low CHIRP for wide-area search; narrows to 10° x 6° on high for focused detail.
Is it corrosion-resistant for saltwater use?
Yes, the bronze housing is tough against marine environments, ensuring long-term reliability.
Traditional marine Fish Finders operate at discrete frequencies such as 50 Kilohertz and 200 Kilohertz, use relatively short-duration transmit pulses, and use narrowband sonar transducers. In contrast, CHIRP (Compressed High-Intensity Radar Pulse) uses a precise sweep pattern of many frequencies within a long-duration transmit pulse from a broadband transducer. The equivalent sound energy transmitted into the water is 10 to 1,000 times greater than a conventional marine Fish Finder. The echo energy returning to the transducer is likewise superior to that generated by a conventional transducer. The combination of CHIRP, a broadband transducer, and Furuno’s superior Digital Signal Processing, results in dramatically increased fish and bottom detection.
