Cursor Readout page
It is often helpful to see information about the cursor and the active markers in the view. Use the Cursor Readout functionality to add information to the readout field in the bottom corner of the view. When enabled, you can see the cursor's position (bearing and distance) and depth in the lower right corner of the view. The depth is calculated from the current tilt and the distance from the vessel.
How to open
This page is located in the Display Options dialog box. The Display Options dialog box is located on the Display menu.

Description
All the presentation modes are listed. Open a presentation mode to find a list of all the views it supports. Open a view to select which information to see in the readout field.
The following information can be provided:
•  Information about the cursor
•  Information about the markers
If you think the text is small and hard to read, double-click on the text field. This will increase the text size.
Note
The views are "linked" together. If you, for example, enable Depth in one Horizontal view, it appears automatically in all other Horizontal views in the different presentation modes.
The following information can be provided:
Current
A current sensor can be connected to the SN90 system. This can for example be an acoustic Doppler current profiler (ADCP). You can read the numerical value of the water current's velocity (the vector information) in the view's bottom right corner.
Bearing / Distance / Depth
The position (bearing and distance) and depth of the cursor's location is shown in the lower right corner of the view. The depth is calculated from the current tilt and the distance from the vessel.
Manual Track
You can start manual tracking by placing multiple markers on a target echo that moves in the view. One or more markers can be placed in the view to identify specific echoes.Each marker is shown as a small triangle with or without a short identifying label. You can see the latest marker's course and speed in the view's lower right corner. The values are calculated based on the last two markers you created and the time between them.
1 Place the cursor on the object you wish to be marked.
2 Right-click and select Place Marker on the shortcut menu.
3 Create a new marker.
The Track Course, Track Speed, and Track Distance values offered now relate to the previous marker you created. The physical location of the individual markers and the specific information provided for the latest marker show you the historical path of the chosen target.
Tip
Once an echo has been provided with a marker in the display presentation it is regarded as an object. The Objects menu provides a list of all current objects. This includes all types of objects including those classified as targets.
