Airmar TM185C Transducer Medium CHIRP With Si-tex 8-Pin

The Airmar TM185C Transducer Medium CHIRP With Si-tex 8-Pin is a professional-grade sonar transducer built for serious anglers and boaters who demand reliable, real-time bottom detection and water-column imaging. After countless hours on the water, you learn that your fishfinder is only as good as the transducer feeding it data, and this dual-frequency unit delivers the precision needed to locate structure, thermoclines, and fish with confidence. Whether you're working shallow flats or deep offshore reefs, the TM185C integrates seamlessly with Si-tex 8-pin legacy and modern systems to give you the edge in navigation and fish location.

Operating in the medium-frequency range of 85 to 135 kHz with a total bandwidth of 50 kHz, the TM185C delivers exceptional target separation and narrow beam angles ideal for medium-depth applications. The transducer combines depth sensing with a fast-response water-temperature probe, critical for identifying thermal layers where fish congregate during seasonal transitions. Rated at 1 kW output power with a maximum operating depth of 457 meters (1,500 feet), this unit performs reliably across saltwater and freshwater environments without compromising signal clarity. The CHIRP (Compressed High-Intensity Radar Pulse) technology sweeps across the frequency range, producing superior target definition and reducing noise interference—a game-changer when reading hard bottoms or distinguishing baitfish schools from structure.

The Si-tex 8-pin connector ensures compatibility with established Si-tex systems and networks that have proven themselves in commercial and recreational fleets for decades. Installation is straightforward for vessels already equipped with compatible transducer cables and thru-hull or transom-mount brackets. This transducer excels aboard center consoles, offshore sportfishers, and working boats where dependable sonar performance directly impacts catch success and navigation safety. The 8.2-pound unit is engineered for long-term durability in harsh marine environments, making it an investment that pays dividends across multiple seasons of hard use.
