2. Click [Fish Size] to show the [Fish Size] settings on the right-side of the window.

Menu item Description
[Graph Display] Sets the orientation of the graph. Select [Horizontal] or
[Vertical] as required.
[Updating Cycle] Sets how often to update the graph.
[Measurement Range] When the measurement mode is other than the bottom
track, set the range to measure fish length.
[Std]: Measure to the bottom of the sea.
[Entire Range]: Measure the entire range including the
depth below the seabed. Fish depth graphs are not mea-
sured deeper than the seabed, so fish echoes may be mis-
recognized as the seabed and correct measurement re-
sults may not be obtained. In such a case, select [Entire
Range].
[Measurement Threshold] Sets the minimum fish length to detect.
[Density Correction] In the [On] setting, the fish density correction function is
activated and corrects the fish length to an appropriate val-
ue. Useful when measuring dense schools of fish. The
[Off] setting may judge a dense school of fish to be one
large fish.
