    9-3 Sea Surface Reflections As ultrasonic pulses at both edges of the 180˚ sector beam are always emitted horizontally along the sea surface regardless of the tilt angle setting, sea surface reflections appear as a thick line extending across the own ship mark. When the sonar is used with a narrow tilt angle, the sea surface reflections cover an e[...]

    9-4 False Echo by Sidelobe An ultrasonic wave is emitted only in the direction set by the TIL T lever , however there are some emissions outside the main beam. These are called sidelobes. The ener gy 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 sidelo[...]
