This mode compares echo intensity between low and high frequencies, and displays echoes

from tiny fish in discriminative colors. This is done by utilizing the fact that tiny fish return a

stronger echo against a high frequency rather than a low frequency. This is done as below.

1. If a high frequency echo is stronger than the corresponding echo on the low frequency, the

high frequency echo is displayed.

2. If the low frequency echo is stronger than or equal to the high frequency echo, it is less

likely to be a tiny fish and therefore is displayed in blue.

3. If the echoes on both frequencies have the intensity corresponding to reddish brown or red,

they are displayed in reddish brown or red: this is necessary to display the zero line and

bottom in reddish brown or red.

In other words, the echoes displayed in orange thru light-blue may be considered to be tiny fish

such as whitebait.
