Simrad ES80 Echo Sounder
- Split beam operation
- FM (linear) and CW pulse forms
- Large dynamic range
- Low self noise
- High ping rate
- Simultaneous transmission of all frequencies
- Several transceivers can run simultaneously
- Wide band frequency sweep ("chirp") in combination with advanced signal processing gives an exceptionally good echo quality
- Define and save your own user settings
- Easy operation with intuitive user interface
- Clear and easily comprehensive echo data

The latest innovations in computer and signal processing technology are used to create a sophisticated, but also intuitive, echo sounder. It can operate with operational frequencies ranging from 10 to 500 kHz. With a suitable transducer, the ES80 can use frequency sweeps ("chirps") across a range of frequencies.
Software changes in version 1.3.1
This software update solves a number of software bugs that have been reported by our users, or detected during our own product testing. New functionality is also introduced.
The following specific changes have been made.
• The bottom hardness function is now available for users with the General Purpose Transceiver
• The factory default settings have been updated. Manual settings for size distribution is now default.
• The ES80 now supports the latest transducers.
• The recording format for CW pulses have been changed to power/angle for users with the Wide Band Transceiver (WBT). These are the same settings as for the ES70 with GPT, and reduces the amount of data. Please note that old user settings must be updated or deleted.
• The maximum temperature permitted from the NMEA MTW datagram has been changed to 40°C. The NMEA MTW datagram provides the current water temperature.
SIMRAD has manufactured fishfinders for more than 70 years and has 25 years of experience using Split beam technology. The first Split beam fishfinder, a 38 kHz model, came on the market in 1984, quickly followed by a 70 kHz model. Today, SIMRAD has a wide range of frequencies from 18 kHz, used for detecting deep water species, up to 333 kHz used for measuring plankton. The Simrad ES80 is the fifth generation Split beam fishfinder where the latest in computer and signal processing technology is used to satisfy the increasing need from our demanding customers:“ Top performance at any depth and easy toperate".The ES80 is a wideband echosounder able to operate at a frequency range of 10-500kHz. With a suitable broadband transducer, the ES80 can sweep (chirp) in a range offrequencies giving increased resolution on longer range. Also, the ES80 will have a TS response curve making it easier to determine the species you are looking at.
