    1. OPERATIONAL OVERVIEW How to Adjust the Gain The GAIN knob adjusts receiver gain (sensitivity). Adjust it so fish echoes are clearly displayed with minimal noise on the screen. Too high a gain setting not only displays excess noise and makes it diffi- cult to discriminate wanted echoes but also causes bottom echoes to be painted in strong colors, resulting in echoes being masked by bottom reflections.

    2. SLANT MODE Tilt Angle The tilt angle shows the direction to which the sound wave is emitted. When the sound wave is emitted horizontally, the tilt angle is said to be 0° and when vertically, 90°. The tilt angle can be set between -5° (upward) to 90° (downward), in increments of 1°. 2.4.1 How to set the tilt angle To manually set a tilt angle, operate the TILT control.

    2. SLANT 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 42: Sweep Angle

    2. SLANT MODE Sweep Angle The sweep angle is the center of the area (range) through which the sonar beam prop- agates sound waves. You can align the beam with the bow of your vessel when the sweep angle is set to 0°. Sweep angle can be adjusted either manually or automati- cally.

  • Page 45: How To Eliminate Weak Echoes

    2. SLANT MODE How to Eliminate Weak Echoes Echoes from targets such as bottom and fish return to the transducer in order of dis- tance to them, and when we compare their intensities at the transducer face, those from nearer targets are generally stronger due to little propagation attenuation and lit- tle absorption.

    2. SLANT MODE How to Adjust Strong and Weak Echoes 2.8.1 How to set AGC (Near, Far and Distance) The AGC functions to automatically reduce the receiver gain only against strong echoes such as a large school of fish. Since weak echoes remain unaffected, a small school of fish becomes easier to detect.

  • Page 48: Seabed Agc

    2. SLANT MODE 2.8.2 Seabed AGC While it is ideal to suppress seabed (bottom) echoes with the AGC alone there are some fishing grounds where this is not possible. To suppress bottom echoes, use the Seabed AGC feature. 1. Open the menu. 2.

  • Page 49: Noise Suppression

    2. SLANT MODE 2.8.4 Noise suppression Removing or suppressing noise from weak echoes such as surface reflections, plank- ton and distant seabeds can help you clear the display. The noise suppression func- tion adjusts the gain level for weak echoes only, leaving echoes schools of fish unadjusted.

  • Page 50: How To Suppress Bottom And Sea Surface Reflections In Shallow Waters

    2. SLANT 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.
  • Page 51 2. SLANT MODE 2.10 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. 2.10.1 How to identify the noise source To eliminate noise effectively, you should first identify the noise source as follows:...
  • Page 52 2. SLANT MODE 2.10.3 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 53: How To Adjust The Rx Bandwidth (Auto Filter)

    2. SLANT MODE 2.10.5 How to adjust the RX bandwidth (Auto Filter) You can adjust the inbound (RX) bandwidth automatically or manually. When this function is enabled, the Auto Filter function automatically adjusts the inbound band- width to display echoes stably, even at high speeds (up to 18 knots). The Auto Filter also compensates for propeller noise and interference from other vessels.

  • Page 54: Reverberation

    2. SLANT MODE 2.10.7 Reverberation You can choose the length of reverberation for the echo signal, with [4 Reverberation] (located at main menu → [1 TX/RX Setting]. Adjusting the reverberation can compen- sate for echoes from plankton, surface reflections and seabed echoes. The settings available are [0] or [1].

  • Page 55: How To Track A School Of Fish

    The default setting is tracking of school of fish. Speed and bearing data are required. The FSV-75 cannot track a school of fish if the level of the echo is too weak. This function requires appropriate data input. For details, see "DATA INPUT REQUIREMENTS"...
