    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.

  • Page 97: How To Enable The Biomass Line

    Gain These procedures explain how you can adjust the gain in the ES70. This controls how “powerful” the echoes are shown in the echogram. The ES70 uses two principles for gain; signal amplification and time varied gain (TVG).

  • Page 98: How To Adjust The Tvg Gain On The Active Menu

    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 99: Power And Pulse Duration

    • About pulse duration on page 113 How to choose passive mode In order to check how much noise the ES70 is receiving, set it to passive mode. This means that the ES70 is not transmitting sound pulses into the water, it is only “listening”.

  • Page 100: How To Change The Output Power

    • A long pulse duration throws a lot more energy into the water, and the digital filters used by the receiver are narrower. These filters will reduce the ES70’s sensitivity for noise, but the length of the transmitted pulse will give you stronger echoes. With the filters, a longer pulse duration will provide longer range, but reduced vertical resolution.

    ES70 records all the targets from the smallest plankton to the largest whale, and provides these findings as a number. For all practical purposes this number will provide you with information about the fish abundance to allow you to decide if it pays off to start fishing.

    Ping-Ping Filter Active the ES70 receiver will still pick up the transmit pulse and implement it in the calculations. A full synchronization of the various acoustic instruments is required. If your own vessel produces excessive noise this will also be taken into the biomass calculations and provide you with inaccurate information.
  • Page 112 Simrad ES70 You can adjust the TVG setting using the functions. Both are located Echogram on the menu. Active 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.

  • Page 113: About Dynamic Range And Display Presentation

    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.

  • Page 114: About Output 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.

  • Page 115: About Pulse Duration

    — Herman Medwin & Clarence S.Clay (1998) In order to control the power output on the Simrad ES70, use the Normal Operation function on the menu.
  • Page 116 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.

  • Page 117: About Bottom Slopes

    For this reason, the ES70 is by default set up to give you a depth reading a few milliseconds before the peak of the pulse. This is done by setting the bottom backstep level to a default value of -50 dB (B).
  • Page 118 Example 13 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.

    (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.

  • Page 121 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 to a positive value.
