The Simrad EK80 is a high-precision scientific echo sounder. The Simrad EK80 is also the most modern "high-end" echo sounder for underwater science purposes, and can operate with several different transceivers.
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 Simrad EK80 can operate a large number of frequencies simultaneously ranging from 10 to 500 kHz. A wide selection of high quality accurate transducers is available.

Key functions include:
- High dynamic range
- Raw data recording
- Low self noise
- High ping rate
- Multi frequency application for species identification
- Simultaneous transmission of all frequencies
- Several frequencies covering same sampling volume
- Wide band frequency sweep ("chirp") in combination with advanced signal processing gives an exceptionally good signal to noise ratio and range resolution
- Remote control
- Store and reload personal settings
- Network interface for raw data recording
- Acoustic Doppler Current Profiler (ADCP) functionality with EC15-3C
The Simrad EK80 operates with single and/or split beam transducers, and provides you with a dedicated built-in application for calibration. With several transceivers available it is well suited for permanent installation onboard a research vessel, but still compact and a natural choice for portable use.
Real time echo integration and target strength analysis in an unlimited number of layers is 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.
The echo sounder system is modular, and you can assemble any combinations of transceivers and transducers to fit your research purposes.
The Simrad EK80 can also be set up with other transceivers than the Wide Band Transceiver (WBT).
A set of data files on the EK80 *.raw format can be downloaded for test and training. The files are provided in ZIP format, and each ZIP file contains a selection of example files. Note that each file is rather big.
Proposals for the collection of multifrequency acoustic data
In ICES Journal of Marine Science, Volume 65, Issue 6 from September 2008, Rolf J. Korneliussen, Noel Diner, Egil Ona, Laurent Berger and Paul G. Fernandes presented a paper with this name. The paper offers very good advice, and we recommend reading it.
