Target Graphs
The target graphs plot, within a circle representing the target measurement range, the
locations of individual fish in relation to your vessel. Two types of graphs are available,
vertical and horizontal. The target position graph can only be displayed on the split
beam screen.
The target graphs can be resized and moved as necessary. Drag an edge of the win-
dow to resize the graph. Drag and drop the window to change location.
Note 1:
The measurement area for the target graphs is shared with the [Fish Size
Graph].
Note 2:
When the measurement mode is set to [Specific Area], the measurement
range of SIZE1 is applied to the target position graph.
2.3.1
Vertical target graph
With a "bird’s-eye-view" of fish below your vessel and your vessel at the center of the
graph display, this graph mode is ideal for keeping track of your heading in relation to
schools of fish and also determining fish distribution surrounding your vessel.
Fish echoes from the last three scans are displayed, which helps to track schools.
To show the [Vertical Target Graph], do the following:
1. Click the [Graph] icon (
) from the InstantAccess bar™ to show the [Graph]
menu.
2. Click the [Target Graph] icon (
) followed by the [Vertical Target Graph]
