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 9 • System overview on page 10 Important As with all other advanced instruments, there are a few important things that you must be aware of. -
Page 12: 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 13 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.

Getting started Getting started This chapter describes how to get started with the basic operation of the ES70 Fish finding echo sounder. Note This chapter assumes that the ES70 Fish finding echo sounder has at least one frequency channel (transceiver and transducer) readily connected. If this is not the case, observe the procedure. - Page 16 Simrad ES70 When the ES70 starts, you may see a dialog requesting permission to upgrade the firmware on the transceiver. This happens if the firmware on the transceiver is older than the firmware provided as a part of the ES70 software. Since functionality...

Getting started If the computer does not switch itself off automatically, use the functionality provided by the operating system to switch it off manually. Switch off the power to the display and to the transceiver(s). Using the trackball All ES70 functions are controlled with the trackball. This trackball is connected to the computer, and by means of the buttons and the wheel you can control all the dialogs and parameter settings. -

Page 73: How To Adjust The Tvg Gain
Operational procedures How to adjust the TVG gain TVG means Time Varied Gain. The whole idea with TVG is that echoes from fish shall have the same echo level (colour) independent of their depths. The ES70 has a TVG range down to 15 000 meters, which for all practical purposes is unlimited. The ES70 does not have a TVG compensated receiver like most other echo sounders. -
Page 74: How To Choose Passive Mode
Simrad ES70 How to choose passive mode In order to check how much noise the echo sounder is receiving, set it to passive mode. This means that the echo sounder is not transmitting sound pulses into the water, it is only “listening”. -
Page 75: How To Adjust The Pulse Duration
Operational procedures How to adjust the pulse duration The length of your transmitted pulse is very important to how you can detect fish. A short pulse duration gives you a very fine vertical resolution. This allows you to detect scattered fish, and you can find those that move near the bottom. A long pulse duration throws a lot more energy into the water, and the digital filters used by the receiver are narrower. -

Page 85: About Tvg Gain
Echo sounder theory The biomass value is also used by the researches to calculate how much fish there is in the ocean. The final result is by far the value provided solely by the echo sounder, as the numbers are subject to numerous calculations and adjustments made by experienced scientists. -

Page 87: 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. - Page 88 Simrad ES70 A pulse duration of 1 mS covers 1,5 meters in the water, and this corresponds to a target separation of approximately 75 cm. This is a typical pulse duration that you may well use down to 250 to 300 meters. If you work in deeper waters use a longer pulse duration, if it is shallower, use a shorter pulse duration.
-
Page 89: About Bottom Slopes
Echo sounder theory About bottom slopes “Bottom slopes” is a well known phenomenon with echo sounders. The edge of the beam (A) hits the bottom first, and starts to give an echo. The bottom detector in the echo sounder measures the strongest echo, detects what it thinks is the bottom, and starts the white line (C). -
