Koden, CVS-1410 Echo Sounder

The Koden CVS-1410 is a professional fish finder / echo sounder designed mainly for commercial fishing vessels and small workboats. It provides high-resolution underwater imaging and accurate depth measurement, making it ideal for both navigation support and fish detection.

The CVS-1410 operates by:

Transmitting ultrasonic sound pulses through a transducer
Receiving echoes reflected from:
- Seabed
- Fish schools
- Underwater objects
Converting signals into:
- Depth readings
- Fish targets
- Seabed structure (echogram)
