SI-TEX 707/50/200T-CX Thru-Hull Transducer f/CVS-126 & CVS-128

The SI-TEX 707/50/200T-CX Thru-Hull Transducer is a dual-frequency bronze transducer engineered for mounting on CVS-126 and CVS-128 fish finder systems. This 1 kW transducer delivers precise bottom and structure imaging for both shallow and deep-water applications, making it an essential upgrade or replacement component for SI-TEX sounder users working serious offshore and inshore waters.

Operating at 50 kHz and 200 kHz, the transducer provides two distinct operational modes optimized for different water depths and target detection scenarios. The 50 kHz frequency delivers a wider 14-foot by 21-foot beam angle, ideal for searching deep water and covering ground quickly over structure. The 200 kHz mode narrows the beam to 3 feet by 5 feet, offering high-definition detail for shallow-water fishing, precise bottom composition analysis, and distinguishing individual fish targets. Bronze construction provides superior corrosion resistance in salt and brackish environments, critical for vessels operating in coastal and offshore conditions where aluminum would corrode rapidly. Temperature compensation is integrated, allowing accurate readings across varying water conditions without manual calibration adjustments.

This transducer is purpose-built for anglers and commercial operators running SI-TEX CVS-126 or CVS-128 systems who need reliable, high-resolution sonar for navigation, fish location, and bottom mapping. Weekend inshore fishermen benefit from the sharp 200 kHz image for shallow flats and jetty work. Offshore tournament and commercial crews depend on the extended 50 kHz range and deep-water capability to locate structure, baitfish schools, and pelagic targets in blue water. Thru-hull mounting integrates seamlessly into hull construction without transducer housing modifications, delivering clean hydrodynamic performance with zero external drag compared to external bracket-mount alternatives.

SI-TEX remains respected among fishing and marine professionals for hardened electronics designed to withstand extended salt water exposure and heavy operational demand. The 707/50/200T-CX carries full compatibility with legacy CVS systems, ensuring existing investment in sonar infrastructure remains current and upgradeable without wholesale replacement of the entire fish finder unit.
