The A-scope picture displays echoes at each transmission with amplitudes and
colors proportional to their intensities on the right one-fourth of the screen. This
feature is useful for close observation of small fish and fish near the bottom.
Note: For the dual-frequency display and vertical split screen, the A-scope
display is only available with the high frequency display. In case of the
horizontal split screen, high and low frequency A-scope displays appear.
