Page 11: About This Manual
The purpose of this manual is to provide the descriptions, procedures and detailed parameter explanations required to allow for safe and efficient use of the Simrad ES70 Fish finding echo sounder system, as well as a thorough understanding of the system parameters and adjustments.
Page 12: Simrad Es70
Simrad ES70 Simrad ES70 The purpose of this chapter is to provide an overall description of the ES70 Fish finding echo sounder system and its main features. Topics • Important on page 10 • System overview on page 11 •...
Page 13: System Overview
• The Simrad ES70 Fish finding echo sounder system is flexible and easy to set up due to its modular design. • Menus and dialogs are operated using a standard computer mouse or a trackball.
Page 14 Simrad ES70 Colour display A standard commercial colour display is used. The display unit is normally not provided by Simrad. Several commercial types and sizes are available. ES70 Marine Computer Simrad can supply the for the ES70 Fish finding echo sounder ES70 Marine Computer system.
Page 15: Simplified System Diagrams
Standard single beam transducer The ES70 must be connected to one or more transducers. A wide range of operational frequencies are available. For more information about the single beam transducers provided by Simrad, consult www.simrad.com. Split–beam transducer The ES70 can be used with Simrad’s advanced split-beam transducers. These transducers are available at frequencies ranging from 18 to 200 kHz.
Page 16: Wave Propagation
Simrad ES70 Figure 4 System diagram with two General Purpose Transceivers Display Unit Processor Unit (computer) General Purpose Transceiver (GPT) Transducer(s) Ethernet switch Wave propagation The velocity of sound wave propagation in the sea varies slightly with temperature, salinity and pressure. The velocity varies between 1440 and 1520 m/s in shallow sea water, while a velocity around 1480 m/s can be expected at 1000 m depth.
Page 17: Bottom Echo
Simrad ES70 The situation is slightly different when observing the echoes from individual fish. The transmitted wave undergoes square-law spreading when travelling from the surface and down to the fish. The swim bladder of the fish scatters a small fraction of the arriving energy in all directions.
Page 18: Split-Beam Operation
Simrad ES70 Figure 7 Bottom echo principles The received echo signal is basically an attenuated copy of the short transmit pulse. The echo signal from a sloped bottom is characterised by having a longer duration and a slower rise and fall time.
Page 19: Observation Range
Simrad ES70 Figure 8 Split beam principles An acoustic wave front propagating towards the transducer arrives at the four quadrants at different times causing the phase angle of the electrical output signal from the quadrants to differ. The fore-and-aft angle is determined from the electrical...

Page 209: About Output Power
In order to know how much power you can use you must know what kind of transducer you are using. Provided that the echo sounder has been installed with a Simrad transducer, and you know what type it is, this is no problem. All necessary parameters about the transducer are then known by the echo sounder, and the software in the sounder will ensure that you do not output too much power.
