  • Page 18: Sonar Mode

    SONAR SYSTEM SUMMARY SONAR MODE A sonar system uses the transmitter-receiver as well as an echo sounder. An echo sounder is only able to search in one direction, down. However, a sonar has a movable transducer and therefore can freely search the entire around a ship, not just the area directly beneath the ship.
  • Page 19 SONAR SYSTEM SUMMARY An echo sounder is only able to search in one direction within some beam angle, beneath A sonar, however, can freely search the broad range, since the transducer’s the ship. angle can be varied not only the horizontal direction but also the vertical direction. By changing the horizontal angle (Sector), the various ranges from the narrow to the full circle are available By changing the transducer’s directional angle (Tilt), the ultra-sound beam angle can...

  • Page 20: Tilt Angle

    SONAR SYSTEM SUMMARY TILT ANGLE The tilt angle shows the direction to which the sound wave is emitted. The tilt angle can be set in step of 1° from 0° to +5° (upward) to 0° to 90° (downward). Find out the suitable tilt angle for a given depth and detection range.

  • Page 21: Tilt Angle And Display

    SONAR SYSTEM SUMMARY TILT ANGLE AND DISPLAY In the shallow water the bottom reflection is prominent, so it is important to be able to distinguish fish echoes from the bottom echo. Therefore the setting of the tilt angle is important to find out the suitable tilt angle. The below shows how fish schools are displayed on the screen when each different tilt angle set.

  • Page 22: Bottom Scan Mode

    SONAR SYSTEM SUMMARY BOTTOM SCAN MODE When this mode is selected, the transmitter/ receiver does not rotate like a sonar, but sweeps from side to side like a pendulum when the sound wave is emitted. The reflected echo from the sea bottom is displayed on the screen sequentially.

  • Page 23: Echo Sounder Mode

    SONAR SYSTEM SUMMARY ECHO SOUNDER MODE The transmitter/receiver faces the sea bottom, and emits the ultra-sound beam. The reflected echo from the sea bottom is displayed on the screen. The image is displayed like a usual echo sounder. The tilt angle and the direction can be changed. The detecting direction can be set by the Bearing keys.
