Upgrade your marine sonar setup with the Garmin B275LH-W Bronze Thru-Hull Transducer, a powerhouse designed for serious anglers chasing fish in coastal waters and beyond. This 12-pin CHIRP transducer delivers exceptional clarity and coverage, scanning depths up to 3,000 feet while providing sharp images of structure, bait schools, and game fish. Whether you're targeting pelagics in shallow zones or probing deep reefs, its dual-band performance—low-frequency power for depth and high-frequency precision for detail—sets it apart from standard transducers.

Crafted with a durable bronze housing and high-performance fairing block, the B275LH-W thrives on boats 25 feet and larger with fiberglass or wood hulls. It handles deadrise angles from 0 to 25 degrees, ensuring a clean install for most planing hulls. At speeds over 30 knots, the fairing minimizes drag and maintains beam integrity, so you get reliable readings even when running offshore. The constant 25-degree wide beam on the high band doubles your search area under the boat compared to narrow-beam alternatives, revealing fish arches and bottom details with stunning resolution.

Key Performance Advantages

• Wide Coverage CHIRP Technology: Low band (42-65 kHz) with 25° to 16° beamwidth punches through to 3,000 feet for deep-water game. High band (150-250 kHz) locks in a steady 25° beam for superior shallow-water separation and twice the fish-finding footprint.
• 1kW Power Output: Drives strong signals for clear targets in varied conditions, from murky bays to clear blue water.
• Integrated Depth and Temperature Sensor: Tracks water column changes in real-time, helping you pinpoint thermoclines where fish stage.
• 12-Meter Cable: Offers flexible routing for clean deck installations without signal loss.
• Xducer ID Technology: Simplifies setup by auto-identifying the transducer to compatible Garmin chartplotters.

Why Anglers Choose the B275LH-W

For inshore runs or bluewater hunts, this transducer excels where coverage matters most. The high-frequency wide beam uncovers schools in the upper water column that narrower units miss, while the low CHIRP band ensures you never lose bottom contact in deeper hauls. Imagine drifting over wrecks with crystal-clear structure overlays or trolling spreads with precise fish ID— that's the edge this unit provides. It's not just about seeing more; it's about interpreting the water column like a pro.

Installation is straightforward for thru-hull setups: fairing block aligns the beam forward for optimal speed performance, and the bronze stem resists corrosion in saltwater environments. Pair it with boats pushing higher speeds, and you'll notice how it holds up without cavitation or bubble interference.

Real-World Applications

Coastal anglers love the B275LH-W for its balance—shallow reef hunting with high-res detail and offshore bottom bouncing with deep penetration. Wood or fiberglass hull owners report fewer false readings thanks to the robust build, and the temp sensor adds value for live bait rigs or lure selection based on water conditions. Skip the guesswork; this transducer turns your display into a fish-magnet tool.
