SI-TEX B-164-20-CX 1Kw Transducer f/CVS-128 CVS-1410

The SI-TEX B-164-20-CX 1Kw Transducer for CVS-128 and CVS-1410 fishfinders is a bronze through-hull sounder that delivers reliable depth and temperature readings in freshwater and saltwater environments. Built for anglers and boaters who demand dependable fish-finding performance, this transducer integrates seamlessly with SI-TEX digital sounder systems and provides the real-time bottom imaging and thermal data essential for locating structure, thermoclines, and active fish. Whether you're running shallow backwater systems or deeper coastal waters, this unit handles the job without compromise.

This transducer features a 20-degree tilt element specifically engineered for hull deadrise angles between 16 and 24 degrees—covering the majority of modern recreational and commercial hulls. The bronze construction resists corrosion in salt exposure, while dual-frequency operation delivers crisp sonar imagery: a wider 22-degree beam angle at 50 kHz for broad coverage and structure detection, and a tighter 6-degree beam at 200 kHz for precise target definition and bottom hardness discrimination. The integrated temperature sensor tracks water conditions in one-degree increments, critical for understanding seasonal fish behavior and thermal stratification patterns that drive feeding activity.

Installation requires through-hull mounting on vessels equipped with SI-TEX CVS-128 or CVS-1410 sounder systems; confirm your hull deadrise angle before purchase to ensure optimal beam projection and reading accuracy. Anglers targeting everything from largemouth bass in shallow impoundments to offshore bottom fish benefit from the clarity and speed this transducer delivers. The 1 Kw power output cuts through turbid water and heavy weed while conserving battery draw—ideal for extended days on the water. Proper installation with a stainless steel through-hull fitting and marine sealant ensures years of trouble-free operation in demanding saltwater and freshwater conditions.
