HORIZONTAL MODE 2.4.3 Relation between bottom echo and tilt angle The figure below illustrates how two schools of fish "a" and "b" are displayed on the screen using three different tilt angles. Case 1: Tilt angle 30° to 40°: This tilt angle will display the entire bottom since it is captured by the full width of the beam.

  • Page 34: Tilt Angle For Surface Fish

    2. HORIZONTAL MODE 2.4.4 Tilt angle for surface fish Sound emitted from the sonar transducer forms an oval-shaped beam with a width of approximately 10° in the vertical direction (vertical beam width at -6dB). The tilt angle indicates the angle between the centerline of the beam and the horizontal plane. Then, if the tilt angle is set to 0°, the centerline is parallel with the sea surface and one half of the emitted sound goes upward, toward the sea surface.

  • Page 38: How To Adjust Strong, Weak Echoes

    2. HORIZONTAL MODE How to Adjust Strong, Weak Echoes 2.7.1 The AGC function automatically reduces the receiver gain only against strong echoes such as the bottom or a large school of fish. Since the AGC function does not affect weak echoes, a small school of fish becomes easier to detect. Adjust it so that the AGC works only on bottom reflections.

  • Page 39: 2Nd Agc

    2. HORIZONTAL MODE 2.7.3 2nd AGC While it is ideal to suppress bottom echoes with the AGC alone there are some fishing grounds where this is not possible. (The high power sonar has the advantage of long- range detection but this can also be a disadvantage, since weaker echoes may be hid- den in strong, unwanted echoes such as the bottom.) If you cannot suppress bottom echoes or sea surface reflections by the AGC function alone, use the 2ND AGC fea- ture.

    2. HORIZONTAL MODE Exclusive Rng S: This feature prevents use of the 2nd AGC, Post 2nd AGC in a certain area at the stern, where unwanted echoes (such as screw noise) can interfere with the 2ND AGC or Area of Post 2nd AGC feature.

  • Page 41: How To Suppress Bottom And Sea Surface Reflections In Shallow Waters

    2. HORIZONTAL MODE How to Suppress Bottom and Sea Surface Re- flections in Shallow Waters In shallow fishing grounds with hard or rocky bottom, bottom reflections often interfere with wanted fish echoes and they can not be eliminated sufficiently with the aforemen- tioned TVG and AGC functions, especially when the Tilt is set to a larger angle in order to track schools of fish approaching within 400 m.

  • Page 42: How To Reject Sonar Interference And Noise

    2. HORIZONTAL MODE How to Reject Sonar Interference and Noise While observing the sonar picture, you may encounter occasional or intermittent noise and interference. These are mostly caused by on-board electronic equipment, engine or propeller noise, or electrical noise from other sonars being operated nearby. 2.9.1 How to identify the noise source To eliminate noise effectively, you should first identify the noise source as follows:...

  • Page 43: Interference Rejector

    2. HORIZONTAL MODE 2.9.3 Interference rejector This control is similar to the interference rejector on echo sounders and radars. It is effective for rejecting random noise and sea surface reflections in rough sea condi- tions. Set it so that noise is just eliminated. Do not use an unnecessarily high setting since it may also reject small, wanted echoes.

  • Page 44: Noise Limiter

    2. HORIZONTAL MODE 2.9.5 Noise limiter Weak, unwanted reflections, colored light-blue or green, appear when the water is dirty, plankton layers exists, or due to ship’s noise. The noise limiter can reduce the effects of these unwanted reflections. Raising the setting causes unwanted reflections to be displayed in colors of blue to background color.

    2. HORIZONTAL MODE 2.9.6 Reverberation You may select the length of reverberation for the echo signal, with [Reverberation] on the [TX/RX Setting] (H1 or H2 tab). The setting range is 0-3. The larger the value, the lower the reverberation effects. Set the length of reverberation properly to make it eas- ier to see the echo signal.

  • Page 68 2. HORIZONTAL MODE School of fish A school of fish appear as a mass of echoes on the screen. By this display pattern, the density of the school on the sonar beam can be found. To find distribution and center point of a school of fish, try several different tilt angles.

  • Page 69: Unnecessary Echoes

    2. HORIZONTAL MODE 2.22.2 Unnecessary echoes Sea surface reflections To reduce sea surface reflections, set the tilt angle to 4° or higher, so the upper edge of the sonar beam does not hit the sea surface, or adjust TVG. When a decreased tilt is used, sea surface reflections cover a large area as illustrated below.
  • Page 70 2. HORIZONTAL MODE Sidelobe echoes (false echoes An ultrasonic wave is emitted only in the direction set by the TILT control, however there are some emissions outside the main beam. These are called sidelobes. The en- ergy of the sidelobe is fairly weak but when the water is comparatively shallow and the bottom is rocky and hard, strong signals are detected by the sidelobe.
