Furuno CM275LH-W Urethane Pocket Mount Transducer - 12-Pin

Discover the power of advanced sonar imaging with this urethane pocket mount transducer designed for serious anglers and professionals who demand precision on the water. Engineered for seamless integration into hull cavities or tanks, it delivers exceptional clarity across a wide range of depths, making it a go-to choice for those chasing big game in deep waters or needing sharp details in shallower zones.

Superior CHIRP Performance for Crystal-Clear Targets

At the heart of this transducer lies dual-band CHIRP technology, sweeping from 42-65 kHz for broad coverage in deep water—perfect for scanning vast areas and locating schools at extreme ranges—and 150-250 kHz for high-resolution imaging close to the bottom. Unlike traditional fixed-frequency sonar, CHIRP continuously varies the pulse to reduce clutter and sharpen fish arches, helping you distinguish between baitfish, structure, and trophy catches with ease. Boaters report consistently spotting wrecks and ledges that others miss, turning frustrating blank screens into productive fishing sessions.

Built Tough for Harsh Marine Environments

Crafted from durable urethane, this 1kW powerhouse withstands the rigors of saltwater exposure, impacts from debris, and constant vibration without compromising performance. The pocket mount design ensures a flush fit, minimizing drag and turbulence for smoother rides at high speeds. Its rugged construction means less downtime and more time on the water, even in rough conditions where lesser transducers might fail.

Effortless Installation and Reliable Connectivity

Installing this transducer is straightforward for those familiar with hull-mounted systems. Prepare your cavity or tank mount by ensuring a clean, level surface, then secure it with marine-grade sealant for a watertight bond. The 12-pin connector plugs directly into compatible Furuno sounders, providing plug-and-play simplicity—no custom wiring headaches. Pro tip: Align it dead ahead and slightly below the waterline for optimal beam patterns that capture the full cone of coverage.

Maximize Your Fishing Success Across Scenarios

Whether you're trolling offshore for tuna, bottom bouncing for snapper, or ice fishing in frozen cavities (with proper adaptations), this transducer excels. The low-frequency band penetrates up to thousands of feet, ideal for commercial fleets mapping the abyss, while the high band reveals thermoclines and individual baitfish with surgical precision. Anglers love how it enhances split-screen views, letting you monitor multiple frequencies simultaneously for a complete picture of what's below.

Long-Term Value Through Smart Maintenance

To keep performance peaking, rinse with fresh water after every saltwater trip and inspect the face for marine growth. Avoid high-pressure washes that could damage the urethane skin. Regular software updates on your display unit further unlock potential, fine-tuning gain and range for your local waters. This proactive approach extends lifespan, ensuring years of reliable service without the need for frequent replacements.
