SI-TEX CVS 128 8.4 Digital Color Fishfinder

The SI-TEX CVS-128 is an 8.4-inch digital color fishfinder for boats that need a traditional 50/200kHz sounder with 600W or 1kW output. It suits coastal fishing boats, commercial operators, and anglers who want a dedicated sounder rather than a chartplotter combination. The display uses digital signal processing and Sona-Tone to present the sonar return.

The 640 x 480 screen provides a practical working area for traditional depth and fishfinding, while the output level depends on the transducer selected. A 50kHz channel is useful for broader depth coverage, while 200kHz provides a tighter, more detailed view in shallower water. The CVS-128 reaches up to 3600 feet under the supplied specification. No transducer is included, and charts or GPS are not listed, so the sounder installation needs to be planned separately.

Who Is This For?

This SI-TEX digital fishfinder suits commercial fishing boats, coastal anglers, and charter vessels that need conventional dual-frequency sonar. It is not ideal for buyers wanting GPS, charts, SideScan, or a transducer-included package; this is a dedicated sounder unit.

Warranty & Support

SI-TEX provides a 2-year limited warranty. The supplied specifications do not state warranty exclusions or service procedures.

The CVS-128 is a traditional sounder for operators who want a dedicated 50/200kHz fishfinder and the option to use more power than a small recreational unit. Its trade-off is its narrow role: no charts, GPS, or modern scanning sonar are listed, and the transducer must be selected separately. Choose it for conventional sounder work, not a multifunction navigation system.
