Airmar TM275C-LHW Transducer 2x Navico 9-Pin MMC

The Airmar TM275C-LHW Transducer 2x Navico 9-Pin MMC is the professional-grade sounder head that serious anglers and commercial operators depend on when precision depth, structure, and fish detection matter most. Built for side-scanning and traditional forward-looking applications, this dual-connector transducer interfaces seamlessly with Navico chartplotter systems, delivering real-time acoustic data in fresh and saltwater environments. Whether you're marking channel ledges on a river system or identifying bottom composition offshore, the TM275C-LHW performs consistently across temperature ranges and deployment conditions that would compromise lesser equipment.

This transducer employs dual 9-pin MMC (Micro-Multi-Connect) connectors, a marine-grade connector standard that ensures reliable signal transmission and withstands corrosive saltwater exposure without degradation. The TM275C-LHW architecture supports both traditional single-frequency and advanced multi-frequency imaging protocols, allowing you to shift between broad-spectrum scanning and focused target identification without swapping hardware. At 13 lbs, the transducer assembly is engineered for through-hull or transom mounting configurations, with internal damping that filters false echoes caused by engine vibration and wave action—critical for maintaining clean sonar imagery at speed or in rough conditions.

The Airmar TM275C-LHW is ideal for Navico-equipped vessels—including Simrad, Lowrance, and B&G branded systems running 9-pin MMC architecture—making it the go-to replacement or upgrade transducer for anglers running integrated glass-bridge displays or legacy systems that demand OEM compatibility. Installation requires proper connector alignment and marine-grade sealant; alignment with your existing MMC wiring harness ensures plug-and-play functionality. Freshwater and saltwater operators alike benefit from Airmar's reputation for multi-year transducer longevity, making this unit a dependable investment for any boat that relies on accurate sonar data to fish effectively and navigate safely.
