EK80

EK80 is a high-precision scientific echo sounder and ADCP system designed to quantify and monitor underwater ecosystems. The EK80 is a  modular system capable of operating several different transceiver and transducer combinations, all through the same operator station.

Based on more than 60 years of research and development in close collaboration with leading marine scientists, this wide band echo sounder system has succeeded the famous EK60, which became an international standard for fish stock assessment. The EK80 is now a wideband system with an operational range from 10 kHz to 500 kHz. The extreme range resolution and improved target characterization allow for a wide range of oceanographic applications.

A wide selection of high-quality accurate surface- and depth transceivers and transducers are available for a flexible system, capable of integration on sensor platforms from small to large.

Real-time echo integration and target strength analysis in an unlimited number of layers are provided as well as storage of raw data for replay or analysis in one of several post-processing software packages. Several post-processing alternatives are available for rapid survey analysis and reporting.

  • Water column profiling

Example data

A set of data files in the EK80 .raw format can be downloaded for tests and training. The files are provided in ZIP format, and each contains a selection of example files. Note that each file is rather big.

Services and support

  • 24/7 Technical support

    Our 24/7 technical support team is there to help at any time, day or night, wherever your vessel is.

  • CONVERSIONS, RETROFIT AND REFIT

    We understand the importance of having the right parts, available in the right place, at the right time.

  • Training

    Ensure that your crew is properly and thoroughly trained. This will reduce operational risk, downtime and maximise return on asset investment.
