Simrad ES70 Surface echogram This echogram is related to the sea surface. Start depth (upper echogram boundary) and vertical range (across echogram) are manually selected by the Start Depth and Range buttons on the Main menu. A This is the start depth of the echogram. In a surface echogram it is normally set up with Start Range = 0, or to a small value to start the echogram immediately under the keel or transducer face. B This is the bottom.
Display views If you have limited your vertical range (using the Range and Start Range settings), the resulting area is used for the biomass calculation. If the seabed is clearly defined with a unique bottom detection, the bottom echo will not be included in the calculations. Therefore, if you switch the bottom detector off, the bottom echo will be included in the calculation. Bottom echogram This echogram is related to the detected bottom.
Simrad ES70 Pelagic echogram The pelagic echogram appears very similar to the surface echogram. However, the biomass calculations are not limited by the bottom detection. Example 11 Start Range in a pelagic echogram In a pelagic echogram, set the Start Range value to 20 meters. This will make the echogram start from 20 meters below the sea surface (provided that the transducer offset has been defined). Set Range to 40 meters.
Display views Echogram markers The echograms provided by the ES70 may contain additional information. The following lines, markers and annotations can be enabled.
Simrad ES70 Related topics • Adding horizontal markers to the echogram on page 55 Hardness line This line marker is enabled in the Echogram dialog on the Active menu. The bottom reflectivity (how “hard” it is) may be monitored using the Hardness line. The Hardness line is an extra thick colour coded line that is added to just below the bottom. The line will not remove information, it will simply “push” the information further down in order to make the bottom easier to see.
Display views Variable depth line This line marker is enabled in the Echogram dialog on the Active menu. When enabled a horizontal depth line is placed wherever you click in the echogram. This is typically used to measure the water depth, the depth of a school, or even single fish. You can click on the line, keep the mouse button depressed, and then drag the line up or down.
Simrad ES70 Important Biomass is an optional function. In order to activate the Biomass information pane and the Biomass line, you must obtain a software license. Related topics • Biomass information pane on page 97 • Adding horizontal markers to the echogram on page 55 Range scales Horizontal range scales in the echogram can be enabled in the Echogram dialog.
Display views The annotations are controlled by the Annotations dialog. Annotations In order to see the annotations on the echogram, they must be enabled in the Echogram dialog. The type of annotation is controlled in the Annotation dialog. Annotations may be added to the echogram to pinpoint special echoes, special events, etc. An annotation can be entered manually using the Annotation dialog, or they can be imported from peripheral devices.

Simrad ES70 Echo sounder theory When you use an echo sounder there are some basic knowledge that you may find it useful to possess.
Echo sounder theory Concepts Observe the following descriptions of key concepts. Topics • Observation range on page 115 • Split-beam operation on page 116 • Bottom echo on page 117 • Wave propagation on page 117 • Biomass on page 119 • Dynamic range and display presentation on page 119 • Bottom slopes on page 120 Observation range Absorption increases dramatically with frequency in salt water.

Echo sounder theory Bottom echo A hard flat bottom reflects the transmitted signal as if it was a mirror. The transmitted pulse hits the illuminated bottom area at nearly the same instant, and the echo from different parts of this area arrive back at the surface also at nearly the same instant. The received echo signal is basically an attenuated copy of the short transmit pulse. The echo signal from a sloped bottom is characterized by having a longer duration and a slower rise and fall time.
Simrad ES70 The ES70 transmits high energy sound wave pulses into the sea. A flat bottom reflects the transmitted wave as if it was a mirror. The propagating energy is spread over a larger and larger area as it travels down to the bottom and up again. The energy is spread over a four times larger area every time the travel distance doubles. Figure 5 Wave propagation from a flat bottom A large school of fish reflects sound waves similarly.
Echo sounder theory Biomass Provided that you use an ES70 with a split beam transducer, or have a valid biomass license on a single beam transceiver, you will have access to the Biomass information pane. This biomass value is an indicator to how much fish you currently have in the current echogram, or in the zoomed area. Every single fish will emit an echo, and the sum of all these registered echoes are presented as a number.
Simrad ES70 Naturally, we can not present all these echoes on the display simultaneously, as this would create a mess of colours. Figure 7 Dynamic range in ES70 -25 dB/W 36 dB Colour Scale 140 dB When 12 colours are used, we create a 36 dB section and give each colour a 3 dB strength. Every colour (3 dB) the represent a doubling of the echo strength. With 12 colours in use this will be a 36 dB colour range from grey to brown. Grey is used for the weakest echoes, while the strongest echoes are brown.
Echo sounder theory A The peak of the bottom pulse B Default bottom backstep level C Approximate bottom backstep level for flatfish detection D Approximate bottom backstep level for seagrass detection Figure 8 The Bottom Backstep principle (CD010217-003) -30 dB -50 dB The bottom pulse basically identifies the bottom depth -70 dB just prior to the peak of the pulse (A). However, this may not be the true bottom.
Simrad ES70 Example 15 Bottom slopes Figure 9 Bottom slopes The edge of the beam (A) hits the bottom first, and starts to give an echo. The bottom detector in the ES70 measures the strongest echo, detects what it thinks is the bottom, and starts the white line. The area above the bottom detection (B) will be masked off, and even though it may contain fish these will not be visible because the echo from the bottom is stronger than those from the fish. The estimated depth (C) will be shown.
Echo sounder theory Parameters Observe the following descriptions of key parameters. Topics • TVG gain on page 123 • Output power on page 125 • Pulse duration on page 127 • Range selection on page 129 TVG gain TVG means Time Varied Gain. When TVG is used in an echo sounder, we also some times refer to it as depth variable gain. The purpose of the TVG functionality is to make all fishes appear with the same echo colour independent of their different depths.
Simrad ES70 d Targets (40 log TVG) Basically, this setting uses the same TVG amplification as Fish, but additional filtering and compensation is implemented. Only echoes detected and interpreted as single fish are shown. The echoes are compensated for their physical position in the beam (beam compensation). This means that fish in the outer region of the beam are adjusted to correct size even though their echoes are weaker.
Echo sounder theory The illustration shows how the gain close to the bottom (B) is larger than just below the transducer (A). The echoes from the fish close to the bottom will then be shown with the same strength (colour) as echoes from pelagic fish. Figure 10 TVG principle 20 log R A 40 log R A The left vessel uses the 20 log R setting. Due to the increasing beam width (C), single fishes are shown larger and larger with increasing depth, even though they may be of identical size.
Simrad ES70 will ensure that you do not output too much power. If you use a third party transducer you must manually check that the output power from the Simrad ES70 does not exceed the power rating. Note If you send too much power into the transducer it will – just like a loudspeaker – be damaged beyond repair. If the transducer receives too much power from the echo sounder, it will also cavitate. This is a physical phenomenon causing the appearance of gas bubbles immediately below the transducer face.
Echo sounder theory beyond the ambient pressure will cause not only total distortion but also the generation of a large cloud of bubbles which will actually decrease the far-field acoustic pressure. The detailed bubble activities during cavitation have been studied in several laboratories.
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. Try out different values, and seek out the pulse duration that provides you with the clearest echo presentation with minimum noise, but with maximum fish detection and separation.
Echo sounder theory Related topics • Adjusting the pulse duration (length) on page 72 Range selection For every frequency (channel) you wish to present on the echo sounder display, you are provided with two echograms.
Simrad ES70 Example 18 Start Range in a surface related echogram In a surface echogram, set the Start Range value to 0 meters. This will make the echogram start from the sea surface (provided that the transducer offset has been defined). Set Range to the current depth plus 20 meters. The echogram will now show the area from the sea surface and down to 20 meters “below” the bottom. The bottom contour is easily detected when the depth changes.
Echo sounder theory Example 21 Start Range and Range in bottom related echogram In a bottom echogram, set the Start Range value to –5 meters. This will make the echogram start from 5 meters above the bottom. Set Range to the 5 meters plus 10 = 15 meters. The echogram will now show the area from 5 meters above the depth, and down to 10 meters “below” the bottom. The bottom contour will appear as a flat line.
Simrad ES70 Installation These are the specific procedures required to get you started with the Simrad ES70. Normally, you will only need to do these procedures once. We recommend that you allow your dealer – with the assistance from a shipyard – to do the physical installation, install the software, obtain a valid license, and get you started.
Installation Connect power to the transceiver(s). Connect the Ethernet cable between the transceiver and the computer. Use an Ethernet switch if you have more than one transceiver. d Connect the necessary cables to the display; power and video. These tasks are described in detail in the Simrad ES70 Installation manual. Do a close visual inspection of the installation. Check each cable and connection to ensure that all wiring is correct.
