    1. OPERATIONAL OVERVIEW Adjusting the Gain The [GAIN] control adjusts receiver gain (sensitivity) for the horizontal and vertical modes. 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 difficult to discriminate wanted echoes but also causes bottom echoes to be painted in strong colors, resulting in echoes being masked by bottom reflections.

  • Page 39: Relation Between Bottom Echo And Tilt Angle

    Fish school "a" Points to consider Normally, a vertically distributed fish school is a better sonar target than the bottom, because it reflects the transmitted pulse back toward the transducer. In case 3, both fish schools “a” and “b” are presented. Generally speaking, however, midwater fish schools tend to be larger than bottom fish schools and they are often displayed near the bottom on the display.

  • Page 40: Tilt Angle For Surface Fish

    2.4.4 Tilt angle for surface fish Sound emitted from the sonar transducer forms an oval-shaped beam with a width of approximately 18 in the vertical direction (vertical beam width at -6dB). The tilt angle is indicated by the angle between the centerline of the beam and the horizontal plane.

  • Page 44: Suppressing Bottom Tail

    When a fish school is located on a long range setting (about 800 meters) and is approaching own ship do as follows: Adjust the tilt to keep the fish school in the center of the sonar beam, namely, fish school is displayed in strongest colors possible. Confirm that the fish echo is displayed in the same color as it approaches.

  • Page 45: 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 hidden in strong, unwanted echoes such as the bottom.)

  • Page 46: 2.7.4 Near Agc

    2. HORIZONTAL MODE 2.7.4 Near AGC When an excessively strong echo is received in shallow or heavily sedimented waters, you may not be able to suppress it by the TVG control alone. In this case, a fish school which is displayed at more than 300 m away may disappear gradually when the ship is approaching the fish school.

  • Page 47: Suppressing Bottom And Sea Surface Reflections In Shallow

    Suppressing Bottom and Sea Surface Reflections in Shallow 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 aforementioned TVG and AGC functions, especially when the TILT is set to a larger angle in order to track fish schools approaching within 400 m.

  • Page 48: Rejecting Sonar Interference And Noise

    1. Stop transmission on the TEST menu, referring to page 10-7, and turn on the power of all on-board equipment one by one while observing the picture. If noise appears on the sonar display, that equipment is emitting noise. Check the offending equipment’s ground and installation.

  • Page 49: Changing Tx Interval

    6. Select QUIT at the top of the menu screen and press the [MENU] key to close all menus. Note: When the sonar is used in shallow water with the range set between 60 m and 200 m and Tx cycle at “9”, bottom reflections caused by the 2nd-to-the-last transmission may appear on near ranges.

    Tracking of bonito and tuna presents a special challenge to the sonar operator: He must try to keep them within the sonar beam, a formidable task considering their high speed and penchant for leaping and diving. The FSV-30, however, with its vertical beam, makes this task easier.

  • Page 99: Approaching

    While a flock of birds hovering over the sea surface is usually a good indication of the presence of a fish school, the sonar can better verify fish school size. 3.13.4 Catching While the sonar operator monitors the sonar for other fish schools, the crew can scatter bait and water to attract fish to the boat.
