SI-TEX 250C/50/200ST-CX Transom Mount Transducer f/CVS-126 & CVS-128

The SI-TEX 250C/50/200ST-CX Transom Mount Transducer is a high-frequency dual-element sonar transducer engineered for SI-TEX CVS-126 and CVS-128 chartplotter systems. This transom-mounted transducer delivers 200 kHz high-frequency performance alongside 50 kHz capability, providing both shallow-water detail and broader coverage for serious fishing operations, commercial surveys, and marine navigation applications.

The dual-frequency design (50/200 kHz) gives operators flexibility across varying water conditions and target depths. The 50 kHz element penetrates deeper water and larger fish schools, while the 200 kHz frequency excels at high-resolution bottom mapping, structure detection, and fish identification in shallow to moderate depths. Weighing 2.15 lbs and dimensioned for efficient transom mounting, this transducer integrates directly with SI-TEX's established CVS navigation and sonar platform, ensuring reliable signal integration without compatibility issues or adapter complexity.

This transducer is suited for commercial fishing vessels, charter operations, and recreational boaters who rely on SI-TEX systems for navigation and sonar data. Whether conducting fish-finding operations, bottom surveys, or detailed structure searches, the 250C/50/200ST-CX provides the dual-frequency capability needed to maximize sonar performance across typical operating scenarios. The transom mount design allows straightforward installation on most hull configurations without extensive modifications.

Marine sonar transducers are mission-critical components that must reliably interface with their host chartplotter system. Selecting the correct transducer model ensures proper impedance matching, signal quality, and sonar image integrity. The SI-TEX 250C/50/200ST-CX is purpose-built for SI-TEX CVS-series units and should not be substituted with generic transducers or models designed for competing systems.
