Mix Display (CH-600 only)
The mix display compares echo intensity between low and high frequencies, and dis-
plays 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 frequen-
cy. The equipment accomplishes this as follows:
• If a high frequency echo is stronger than the corresponding echo on the low fre-
quency, the high frequency echo is displayed.
• 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.
In other words, the echoes displayed in orange through light-blue may be considered
to be tiny fish such as whitebait. When the mix display is active the indication MX ap-
pears at the top of the display.
To use the mix display effectively, it is important that the gain for both the low and high-
frequencies is set properly. When searching for young fish such as whitebait, follow
the procedure below. For detailed information about gain adjustment, see the next
section.
