SI-TEX 307/50/200T-CX Thru-Hull Transducer f/SVS-650, CVS-126 & CVS-128

The SI-TEX 307/50/200T-CX thru-hull transducer is a precision sonar sensing device engineered for compatibility with SI-TEX fishfinder models SVS-650, CVS-126, and CVS-128. This transducer converts the sonar head's frequency output into usable underwater imagery, delivering the acoustic foundation that serious anglers and vessel operators depend on for accurate fish location and bottom profiling in saltwater and freshwater environments.

Thru-hull transducers operate by transmitting high-frequency sonar pulses directly through the boat's hull into the water column, then receiving reflected signals to create real-time sonar imagery on the chartplotter display. The 307/50/200T-CX model features a 50 kHz operating frequency optimized for mid-range bottom detection and fish identification at moderate to deeper depths. The thru-hull design eliminates the mounting complexity of transom-mount alternatives while providing superior signal consistency, as the transducer element remains permanently submerged and unaffected by water surface conditions, boat attitude changes, or cavitation during high-speed operation.

This transducer suits offshore fishing operations, coastal surveys, and freshwater bass and walleye anglers who prioritize consistent bottom returns and target definition over extended distance ranges. Weekend recreational boaters and professional charter operations alike benefit from the stable imaging that thru-hull installation provides. Installation requires a through-hull aperture and basic hull penetration; careful sealant application prevents saltwater intrusion that can compromise vessel integrity. The 307/50/200T-CX pairs directly with its compatible SI-TEX sonar units, ensuring factory-tuned frequency matching and signal optimization out of the box.
