  • Page 11: Basic Information

    Simrad SH90 Basic information The Simrad SH90 is an omnidirectional high frequency sonar. It is designed for all sized fishing vessels, both purse seiners and trawlers. The operational frequency is 114 kHz. The cylindrical multi-element transducer allows the omnidirectional sonar beam to be tilted electronically from +10 to –60 degrees.

  • Page 54: Display Modes

    Simrad SH90 DISPLAY MODES The SH90 sonar provides you with several different display modes. These have been created to cover all your operational needs for various types of fishing and fishing gear. Bow up When Bow up mode is selected, the vessel symbol is stationary on the screen with the bow pointing upwards.
  • Page 55 Display modes Bow up/180° Vertical When the Bow up/180° Vertical mode is selected, the upper part of the screen shows a curtailed Bow up presentation, while the lower part shows a 180 degrees Vertical slice presentation. This mode is mainly intended for trawlers, where the vertical view acts as a multibeam echo sounder.
  • Page 56 Simrad SH90 Dual 1 The Dual 1 mode is a kind of “two sonars in one” operation, where each presentation is updated for every second transmission. All settings can be set individually for each of the two presentations. This makes the dual mode especially useful for optimizing settings by directly comparing the two presentations.

  • Page 69: Basic Theory

    Basic theory BASIC THEORY This chapter explains some of the basic theory related to settings, error sources and noise conditions. Settings A sonar will transmit a sound wave into the water around the vessel. When this sound wave hits fish, bottom, or other objects in the water, a part of the sound will be returned as echoes.

  • Page 70: What Is Agc

    Simrad SH90 What is AGC? means Automatic Gain Control. The AGC will automatically scale the received echo data to maintain a proper dynamic range based on all the incoming echo values. In addition to Off, the strength of the filter can be set to three different levels.

About Gain You can adjust the gain in many different ways, but the most important is the setting made by the...

  • Page 72: What Is Rcg

    Simrad SH90 What is RCG? means Reverberation Controlled Gain. This is a two-dimensional filtering of the received echoes in order to suppress unwanted surface and bottom reverberation. If you select Strong, the bottom echoes will disappear altogether if the bottom is flat, while schools of fish close to the bottom will be easier to see.

  • Page 73: Noise And Reverberation

    Basic theory By means of a medium tilt angle (B) you will most likely be able to pick up scattered fish or schools if these are located at some distance above the bottom. The upper school in the illustration will appear on the sonar picture before the bottom echo, while the lower school will easily be disguised by the bottom echoes.

  • Page 74: Reverberation

    Simrad SH90 Figure 16 Cavitation When the bubbles collapse, they cause very strong local shock-waves in the water. These may be audible and can also damage the propeller blades. In addition to this, the cavitation will generate very strong reverberation, commonly seen as a red stripe of echoes behind the vessel.

  • Page 75: Blocking

    Basic theory The echoes from the bottom will vary with how uneven the bottom is, what kind of bottom you have under your vessel, (rock, mud, sand etc.) as well as your current tilt setting. The echo from the sea surface will vary with the current sea state and your current tilt setting.

  • Page 76: Layers And Deflections

    Simrad SH90 How to check for electrical noise This procedure provides a simple method to check the electrical noise. Switch off all electric equipment that can cause electrical noise. This includes motor, propellers, thrusters, winches, cooling- and air conditioning systems, pumps, cranes, hydraulic systems etc.

  • Page 77: Deflections

    Basic theory Deflections On warm days – especially during summer – the sea surface will be heated by the sun, and the water temperature will gradually decrease with increasing depth. Figure 19 Water temperatures on warm days (CD015005G) When the temperature decreases (A) closer to the bottom, the sonar beam is deflected down as indicated by the illustration.
