Please fill in the short form below with your question, either about the Simrad EK60 Scientific, or for some technical advice. Please include details of your vessel if you feel they will help us answer your query.
Thank you and we look forward to hearing from you!
The Simrad EK60 has now been discontinued - Simrad have now introduced the revolutionary EK80, full details are available here
The Simrad EK60 is a split-beam Windows™ operated echo sounder with a built-in calibration utility. It is specifically suited for permanent installation onboard a research vessel.
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. The Simrad BI60 is one post-processing alternative for rapid survey analysis and reporting. The Simrad BI60 is a free-ware application and an integrated part of the EK60 echo sounder system. System components
The basic Simrad EK60 echo sounder system consists of one transducer, one transceiver unit and one processor unit (computer).
The Simrad EK60 uses the Simrad ER60 echo sounder software application.
A typical installation onboard a research vessel will involve several frequencies with a maximum of seven ranging from 18 to 710 kHz. Several frequencies are needed to cover the broad scope of a marine acoustic survey ranging from studies of plankton to large fish schools from shallow coastal waters down to the deepest oceans.
In addition, recent research has shown that simultaneous use of several discrete echosounder frequencies not only improves fish stock estimates, it can also be used for species identification and discrimination. Each species seems to have a unique acoustic frequency response (signature) due to frequency dependent acoustic backscattering. This new and growing understanding greatly improves the value of hydroacoustics to obtain information about marine resources.
