SI-TEX SVS-760 600W Dual Frequency Fishfinder Sounder

The SI-TEX CVS-760 is a dedicated 7-inch vertical fishfinder for boats that need a traditional dual-frequency sounder rather than a chartplotter. Its 600W RMS output and 50/200kHz channels suit commercial skiffs, coastal trap boats, and bottom-dropping charter boats where a straightforward sounder screen is easier to work with than a multifunction display. No transducer is included.

The 480 x 640 vertical layout gives the screen a useful tall shape for watching the water column and bottom return. The 50kHz channel is suited to broader depth coverage, while 200kHz provides more detailed returns in shallower water. The unit accepts 11-35V DC, so it can fit both 12V and higher-voltage vessel systems. NMEA 0183 input and output are listed, but this is not a networked chartplotter or modern SideScan unit.

Key Features

- 7-inch vertical color TFT LCD – Provides a dedicated screen for traditional fishfinding.
- 600W RMS output – Supports the listed conventional sounder power.
- 50kHz and 200kHz dual frequency – Gives the operator two traditional sonar bands for different conditions.
- Digital SonaTone processing – Processes the sonar return for the CVS-760 display.
- 11-35V DC input – Fits a wide range of marine electrical systems.

Who Is This For?

This 600W dual-frequency fishfinder suits commercial crabbing skiffs, coastal trap boats, work vessels, and bottom-dropping charter boats. It is not ideal for buyers wanting charts, GPS, SideScan, or a transducer-included package; the sounder and transducer must be selected separately.

Compatibility

Confirmed features include NMEA 0183 input/output, 50kHz and 200kHz sonar, Digital SonaTone processing, and a 600W RMS output stage. The supplied information does not identify specific transducer models, NMEA 2000, radar, autopilot, GPS, or third-party chartplotter compatibility. No named incompatible system was provided; verify the transducer and NMEA wiring before installation.

Warranty & Support

The CVS-760 is the specialist choice for traditional fishfinding where 50/200kHz coverage and a vertical display matter more than mapping or network features. The trade-off is the missing transducer and lack of modern scanning sonar. Choose it for a planned conventional sounder installation, not as a general-purpose chartplotter.
