Display views In order to open an information pane, you must first click in an echogram presentation to make it “active”. By doing this you select frequency channel (transducer). In most cases, the data in the information pane you open will only be valid for the selected echogram. Some of the information panes are optional. They are thus not available for use unless a licence code is available. In order to obtain a licence, consult your local dealer.
Simrad ES70 Fish Position Click this icon to open and close the Fish Position information pane. This pane shows you the position within the beam of the detected single echoes. The beam and the fish echoes are seen from above. The same echo information is also provided in the Echo Position information pane, but the beam is there seen from the side to add the depth perspective. The Fish Position information pane is only available if your ES70 is equipped with one or more split beam transceivers.
Display views Note This navigational information on the Title Bar must not be used for navigation! Geographical location Provided that a GPS system is connected to the ES70, this field on the Title Bar will display the vessel’s geographical position in longitude and latitude.

Display views 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. Figure 14 Surface 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. B This is the bottom.
Simrad ES70 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.
Display views Pelagic echogram The pelagic echogram appears very similar to the surface echogram. However, the biomass calculations are not limited by the bottom detection. Example 7 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.
Simrad ES70 Lines, markers and annotations in the echograms The echograms provided by the ES70 may contain additional information.
Display views Hardness line Figure 18 example Hardness line 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. The colour coding contains the hardness information.
Simrad ES70 Variable depth line Figure 19 Variable Depth line example 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. The variable depth line is enabled in the Echogram dialog on the Active menu.
Display views Biomass line Figure 21 example Biomass line, The biomass may be monitored using the Biomass line. The biomass line is an extra thick brightly coloured line that is added to the echogram. The line will identify the variations in biomass. To adjust the view, use the scale. The changes made in the Calculation Interval dialog will not have an effect on the Biomass line. Remember that you can also measure the biomass using the Biomass information panel.
Simrad ES70 Annotations 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. In order to see the annotations on the echogram, they must be enabled in the Echogram dialog. Information panes The Simrad ES70 offers several information panes to provide additional and detailed data from the echogram.
Display views Depth information pane Figure 22 Depth information pane To open this information pane, click the Depth icon on the Title Bar. The Depth information pane displays the current depth for the chosen transducer and frequency. The Tool button opens the Bottom Detector dialog. This dialog is also available from the Active menu.

Operational procedures 1 Click the Active icon under the Main menu to open the Active menu. → Active menu on page 107 2 On the Active menu, click Bottom Detector to open the Bottom Detector dialog. This dialog is used to define various parameters associated with the bottom detection. These include the depth range, where the ES70 searches for the bottom. 3 Enter a Minimum Depth. This setting eliminates all unwanted bottom detections from the transducer surface and down to the defined depth.
Simrad ES70 3 4 Increase the Bottom Backstep level (make it more positive). A typical setting would be approximately -30 dB, but you will need to experiment to find the best value for the operational frequency and the current bottom and sea conditions. The ES70 will now provide increased penetration, and show you a detected bottom that is slightly deeper than the actual value. This will cause the flatfish to be shown as if they were located “above” the bottom.

Simrad ES70 How to adjust the fish length for correct calculations The ES70 measures and records the target strength (TS). The researchers at the Norwegian Institute for Fishery Research have compiled a set of algorithms based on extensive testing with the various species, and these are used by the ES70 to calculate the length of the fish based on its target strength. However, the target strength differs between the various species.

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 if there is real fish below the keel. The number provided to display fish abundance is relative, and after some use your experience will be a valuable factor when the decision is made. The biomass value is also used by the researches to calculate how much fish there is in the ocean. If you know the fish specie and the size of the fish, you can calculate number of individual fishes for a given volume of sea.
Simrad ES70 You can adjust the TVG setting using the Echogram or TVG functions. Both are located on the Active menu. Because the strength of the echoes will become weaker with increasing depth, the echo sounder will automatically amplify the deepest echoes more than the shallower echoes. In fact, the gain will increase proportional to how long the echo sounder “waits” for the echoes.
Echo sounder theory About dynamic range and display presentation The ES70 echo sounder has a dynamic range of 140 dB. This means that the sounder can receive both very strong and very weak echoes. Actually, the ES70 will detect echoes from plankton to whales, bottom on most depths, and present the information free from distortion. As a comparison, our old echo sounders ES380 and ET100 had - using analogue TVG - a dynamic range corresponding to approximately 65 dB.
Simrad ES70 About output power The echo sounder’s transducer converts the electrical input power to a sound transmitted into the water. In the majority of the transducers manufactured by Simrad the transducer’s power efficiency is between 50 and 75%. This means that between 50 and 75% of the input power is transmitted as sound. Transducers from other manufacturers may have as low as 5% power efficiency. Naturally, it is very important that you check this parameter when you wish to purchase a transducer.
Echo sounder theory Several extraordinary physical phenomena are associated with acoustic cavitation. Chemical reactions can be initiated or increased in activity; living cells and macromolecules can be ruptured; violently oscillating bubbles close to a solid surface can erode the toughest of metals or plastics; light may be produced by cavitation (sonoluminescence).
Simrad ES70 The pulse duration can be adjusted according to the current depth and what kind of fish you are looking for. The deeper you wish to see, the longer pulse duration should be used. Remember that in ES70 echo sounder, the pulse duration and the bandwidth is mutually dependant.
Echo sounder theory All operational frequencies have different pulse durations. The difference between for example a 50 kHz and a 38 kHz transducer is however not large: • A 50 kHz transducer can be used with pulse durations from 0,12 mS to 2 mS • A 38 kHz transducer can be used with pulse durations from 0,26 mS to 4 mS. Basically, both these frequencies will provide you with the same detection ability.
Simrad ES70 On the echogram the white line will then “climb” up the slope. Make sure that you do not increase the sensitivity too much. This will have an effect on the fish detection on a flat bottom, and the biomass values will be wrong. Our experience show that an approximately -75 dB bottom backstep value can be used safely. By increasing the bottom backstep value (make it more positive) the bottom will be detected later, and it will appear to be deeper.
Echo sounder theory Example 15 Using the Bottom Backstep parameter for flatfish detection If you fish for sole, flounder or similar species, you can use the Bottom Backstep parameter to enhance the detection of the fish. Increase the bottom backstep value (make it more positive) so that the bottom is detected slightly deeper than the correct depth. The ES70 will then “push through” the fish better, and the flatfish will be shown as they are located “above” the bottom.
Simrad ES70 Upper echogram: Pelagic or surface related When you need to establish a vertical depth range, why not let the echo sounder choose it for you. On the main menu, set Range to Auto. You can also define your own depth range. To establish a depth range from the surface and down to the bottom, set Range to a suitable depth, and Start Range to 0 (zero) meters. A phased area may also be established.
Echo sounder theory When you use bottom expansion, the water surface is not the reference any longer, but the bottom is. It is always 0. That means that the bottom in this echogram will always be flat, even though it may vary in the upper echogram. To choose a vertical depth range for the bottom expansion, set Range to a positive value. This is the total vertical range of the echogram. Then, set Start Range to a negative value. This is the echogram’s start height above the bottom.
