    EMERGENCY STOP BUTTON ON HULL UNIT The EMERGENCY STOP button on the hull unit stops the raising or lowering of the transducer in case of an emergency. The transducer stops moving when the button is operated, a warning mes- sage appears and the transducer cannot be raised or lowered. The transducer is also stopped when the ratchet wrench in the hull unit, which is used to manually raise the transducer, is re- moved from its holder.

  • Page 32: Tilt Angle

    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.

  • Page 33: Automatic Tilt

    2. SLANT MODE 2.4.2 Automatic tilt The AUTO TILT key automatically scans the tilt angle within the selected width. This is useful when you want to find the center depth of a school of fish. You can set the range for automatic tilt at [1 Auto Tilt Range] (located at [9 Installation Setting] Operation Setting] [6 Sweep/Tilt Settings]).

  • Page 34: Relation Between Bottom Echo And Tilt Angle

    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 35: Tilt Angle For Surface Fish

    2. SLANT MODE 2.4.4 Tilt angle for surface fish Sound emitted from the sonar transducer forms an Sea Surface oval-shaped beam with a width of approximately 10° for 80kHz and 13° for 70kHz in the vertical di- Tilt Angle 0° rection (vertical beam width at -6dB).

  • Page 36: 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. In Slant Mode, you can align the beam with the bow of your ves- sel when the sweep angle is set to 0°. Sweep angle can be adjusted either manually or automatically.

    2. SLANT MODE How to Measure Range and Bearing to a Target You can measure the range and bearing to a fish school, or other echo. 1. Operate the trackball to place the cursor on the target to which you want to mea- sure the range and bearing.

  • Page 39: 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.

  • Page 40: How To Set Near And Far Gain

    2. SLANT MODE 2.7.2 How to set near and far gain You can set a different gain level for nearby echoes and far echoes with Near Gain and Far Gain functions. 1. Open the menu. 2. Select [2 Gain Setting], then left-click. 3.

  • Page 41: How To Adjust Strong And Weak Echoes

    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 42: 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 43: 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 44: 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, especially when the TILT is set to a larger angle in order to track schools of fish approaching within 400 m.

  • Page 45: How To Reject Sonar Interference And Noise

    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 46: Interference Rejector

    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 47: 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 48: 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 49: 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"...

    2. SLANT MODE 2.12.2 Fish mode The automatic echo target lock function automatically tracks the operator-selected school of fish. When [2 Tilt Interlock] (located in the [8 Target Lock] menu (see previ- ous page) is set to [Tilt & Range], and the tracked school of fish goes out of the zone in the range direction, the range and tilt are automatically controlled according to the position of the school of fish.
