Naval Echo Sounders

NES-DF

The Nautel Naval Echo Sounder (NES-DF)  is a compact, state-of-the-art acoustic system. Its compatibility with third party transducers makes it ideal for retro-fit on existing naval vessels.

The system’s bottom detection capability is enhanced by digital signal processing.

A wide range of selectable operating frequencies – 12 / 30 / 50 / 200 kHz – are offered as standard.

Synchronous operation with multiple transducers on different frequencies offers the option to integrate, process, and display environmental data such as pressure, temperature, density, salinity, and sound velocity of the water.
