SI-TEX 250/120ST Transom Mount Transducer f/CVS106, CVS106MKII, CVS106L & CVS106LMKII

The SI-TEX 250/120ST Transom Mount Transducer is a single-frequency sonar transducer engineered specifically for SI-TEX chartplotters and fish finders, including CVS106, CVS106MKII, CVS106L, and CVS106LMKII models. Operating at 120 kHz with 600W peak power output, this transom mount transducer delivers consistent bottom tracking and fish detection across diverse water conditions, from shallow coastal areas to moderate depths.

The transducer features a 15-degree beam angle that provides focused sonar coverage, ideal for precision bottom mapping and identifying structure in target areas. Its plastic housing is corrosion-resistant, essential for saltwater and freshwater environments where exposure to moisture and spray is constant. The 30-foot cable allows flexible installation on transom-mounted applications, while the 8-pin connector ensures secure, weatherproof connection to compatible SI-TEX display units. Dual functionality includes water temperature sensing and speed-through-water measurement, delivering real-time thermal and performance data alongside sonar imagery.

This transducer is designed for recreational and professional anglers who rely on SI-TEX systems for reliable sonar performance. The 120 kHz frequency penetrates effectively to moderate depths while maintaining target resolution, making it suitable for both open-water and structure-rich environments. Users operating SI-TEX legacy and current systems benefit from direct compatibility and straightforward installation without adapter requirements.

The transducer weighs 2 lbs and measures 8 x 3 x 8 inches, keeping mounting footprint minimal while maintaining robust construction. As a factory-matched component for SI-TEX chartplotter systems, the 250/120ST transducer integrates seamlessly with established SI-TEX sonar networks, preserving system accuracy and eliminating integration uncertainty common with third-party transducers.
