Fish Targets in Contour Window
The fish targets that you collect may also be viewed in the contour window if you have
contour chart coverage for that area. To include fish targets on the contour display,
press Setup, Contour, Targets and select one of the options to Show Targets. The
targets are always displayed as fish, initially using 3D versions of the four fish icons of
different sizes and colors.

Groups May Merge Into One Target
As the vessel moves beyond a group of 3D fish targets, the targets will group
themselves together into a school. This helps you identify the targets more easily as
they recede into the distance. The color of the school indicates the number of fish in the
group. White or light blue indicates a small number of fish; dark blue indicates a larger
number.
Add Depth or Age Notes to Fish Targets
If you wish, you can choose to add a depth note or age note to the contour fish targets.
Touch Setup, Contour, Targets and choose Show targets with depth to include each
fish’s depth next to its target icon. Choose Show Targets with age if you would prefer to
see how much time has passed since the target was acquired. Maestro Navigator will
attach a note to each target, stating how many hours have passed. The age is rounded
to the nearest tenth of an hour (six-minute increment).
