Simrad TM185H-W High Wide CHIRP 9-Pin Transom Mount

The Simrad TM185H-W High Wide CHIRP 9-Pin Transom Mount transducer is purpose-built for anglers and boaters who demand precise, real-time sonar performance in freshwater and saltwater environments. This transom-mounted solution delivers the imaging clarity and range needed to locate structure, thermoclines, and fish with confidence, whether you're working shallow flats or deeper channels. The High Wide CHIRP technology provides exceptional target separation and definition—critical when you're competing for fish or navigating complex bottom compositions.

Built on Simrad's proven High Wide CHIRP frequency architecture, the TM185H-W broadcasts a broad bandwidth pulse that excels at discerning small targets and layered water columns with remarkable clarity. The 9-pin connector interface ensures seamless integration with compatible Simrad chartplotters and multifunction displays, while the transom-mount design—engineered for hull-speed operation—minimizes turbulence interference and maximizes signal stability. Weighing 8 lbs, the transducer is robust enough to handle extended seasons and demanding conditions without performance degradation.

This transducer is ideal for center-console and open-boat anglers, as well as cruising boaters who value integrated sonar accuracy across a wide operational envelope. Installation on the transom places the transducer in clean water flow, ensuring uninterrupted CHIRP transmission and reception from idle speed through full throttle. Verify 9-pin compatibility with your Simrad unit before purchase; this transom mount pairs seamlessly with current-generation Simrad displays and legacy systems supporting the 9-pin standard.
