Unlock Crystal-Clear Underwater Insights with Advanced CHIRP Technology

Picture this: you’re out on the water chasing trophy fish like bluefin tuna or cod, and your sonar screen lights up with precise marks showing exact depths, bait schools, and bottom structures. The Garmin B265LH Bronze Thru-Hull Transducer makes that vision a reality. Engineered for serious anglers and boaters who demand top-tier performance, this powerhouse delivers exceptional target separation and detail across vast depths, turning every trip into a potential record-breaker.

Unlike standard fixed-frequency transducers, the B265LH’s broadband CHIRP capability lets you dial in the perfect frequencies—think 60 kHz for tuna or 175 kHz for cod—fine-tuning your setup for species-specific success. Its low-frequency array sweeps from 42 to 65 kHz with a wide beam that adapts dynamically, while the high-frequency ceramic hits 130 to 210 kHz for pinpoint accuracy on tighter targets.

Built for Deep Water Domination

This 1kW beast plunges to 3,000 feet, capturing intricate details of the water column and seafloor that lesser units miss. Whether you’re bottom bouncing for snapper or scanning for wrecks in deep offshore waters, the bronze housing withstands harsh marine environments, ensuring reliability season after season.

• Robust Bronze Construction: Corrosion-resistant and ideal for saltwater exposure, outperforming plastic alternatives in durability.
• Adaptive Beamwidth: Low CHIRP offers 25° to 16° coverage for broad searches; high CHIRP narrows to 10° to 6° for surgical precision.
• Integrated Depth & Temperature Sensing: Real-time data to track thermoclines and plan your drifts effectively.

Seamless Integration for Your Vessel

Designed for thru-hull mounting on hulls with 0° to 20° deadrise, installation is straightforward with the included high-performance fairing block. This fairing optimizes water flow at speeds over 30 knots, minimizing turbulence for cleaner reads even at cruising pace. The 39-foot cable gives you flexibility in routing to your Garmin chartplotter or sonar module.

Pair it with compatible Garmin units to unleash its full potential—experience how CHIRP transforms vague arches into distinct fish returns, helping you separate keepers from baitfish with ease.

What’s Included for Easy Setup

• Bronze thru-hull transducer element
• High-performance fairing block
• Comprehensive installation instructions
• 39-foot 12-pin cable

Everything you need to get up and running, so you spend less time wrenching and more time fishing.

Elevate Your Fishing Game

Investing in the B265LH means gaining an edge in bottom discrimination—spot hard rock from soft mud, identify structure-holding fish, and even detect subtle bait balls that drive predators. Boaters rave about its noise rejection in rough conditions, providing stable images when others falter. For offshore adventures or inshore precision, this transducer sets a new standard in sonar clarity.

Frequently Asked Questions

What makes the Garmin B265LH different from other thru-hull transducers?

Its dual-channel CHIRP technology allows tunable frequencies across wide bands, delivering superior target detail and bottom discrimination compared to fixed-frequency models. The bronze build adds marine-grade toughness for long-term reliability.

Can this transducer handle high boat speeds?

Yes, the included fairing block ensures optimal performance at speeds exceeding 30 knots by streamlining water flow over the face, reducing cavitation and maintaining accurate readings.

What’s the maximum depth capability?

It reaches up to 3,000 feet, making it perfect for deep-water fishing where high-power sonar is essential for clear images.

Is it suitable for hulls with deadrise angles?

Absolutely, it fits deadrise angles from 0° to 20°, accommodating most planing hulls with the adjustable fairing.

Does it measure water temperature?

Yes, the built-in temperature sensor provides accurate surface water readings, crucial for locating fish in varying conditions.

How does CHIRP benefit anglers?

CHIRP scans multiple frequencies simultaneously, producing sharper images with better fish arches and structure definition, improving hook-up rates by highlighting prime targets.

What cable length is provided?

A generous 39-foot 12-pin cable offers plenty of reach for clean installations in larger consoles.
