Visual Objects menu
The Visual Objects menu controls which graphical elements that are shown in the different views. These graphic elements include markers, vectors and targets that are tracked. The majority of the functions are "on/off" buttons to enable or disable these graphic elements in the various views.

How to open
Select Visual Objects to open the menu.

Visual Objects is located on the Display menu. The function is not available for the Inspection views.
Description
Only brief descriptions are provided.
Tip
If you do not need to use the menu system, you can hide it. This allows more space for the echo presentation. Use Menu on the top bar to hide or show the menu.
Image
When the menu system is hidden, it appears temporarily on the left or right hand side of the screen if you move the cursor to that position.
The choices in the this menu depends on which view in the display presentation that is currently "active". The menu may therefore change from one view to another. The screen capture may not show you all the menu choices.
Note
Before you can change the settings related to a view, you must click inside the view to activate it. The changes you make are by default only valid for the active view. Several of the functions offer Apply to All. If you select Apply to All your setting is applied to all the views in the current presentation mode.
•  Position Object Sizes
The Place Marker function allows you to create a marker at the current position of the cursor. Each marker is shown as a small triangle with or without a short identifying label. When you start target or position tracking, a marker is used to identify the object. With this function you can increase or decrease the size of the markers.
Use this function to find the object sizes that fit your preferences. This may for example depend on your physical distance from the screen. The choice you make is saved with the user settings.
•  Bottom Profile
For each ping transmitted for a vertical view, the SU90 offers bottom detection functionality. This is an "on/off" switch. Set Bottom Profile to On to see a bottom contour in the current view. Select Apply to all if you wish to use the chosen setting in all the vertical views in the SU90 presentation.
•  Minute Markers
In order to maintain a visual presentation of your vessel’s previous movements, you can draw these with a line. This line is drawn after the vessel symbol in the sonar views, and visualizes your past movements. We refer to this line as the Track Line. The Minute Markers function adds markers to the track line. These markers indicate how far you have sailed for each minute. The minute markers are shown as small circles on the vessel’s track line.
To draw the track line use the settings on the Track Line page. The Track Line page is located in the Display Options dialog box. The Display Options dialog box is located on the Display menu.
•  Markers
The Place Marker function allows you to create a marker at the current position of the cursor. Each marker is shown as a small triangle with or without a short identifying label. Use this function to control if and how the marker symbols are shown in the currently active view. Select Apply to all if you wish to use the chosen setting in all the views in the SU90 presentation.
•  Tracks
When you start target or position tracking, a marker is used to identify the object. Each marker is shown as a small circle with or without a short identifying text. Use this function to control if and how the tracking markers are shown in the currently active view. Select Apply to all if you wish to use the chosen setting in all the views in the SU90 presentation.
•  Minute Markers Tracks
When you start a target track, a dedicated marker is used to identify the object you are tracking. When enabled, Track History draws a position history line after each tracked target. The line identifies the previous positions of the target. This function adds markers to the track history. These indicate the target’s travelled distance for each minute.
•  Track History
When you start a target track, a dedicated marker is used to identify the object you are tracking. Each marker is shown as a small circle with or without a short identifying text. In most cases, the target will move and continuously change its position relative to your own vessel. When enabled, Track History draws a position history line after each tracked target. The line identifies the previous positions of the target. This allows you to manually predict its current heading.
•  Speed Vector
Speed Vector shows you the predicted course and speed of the tracked target. The prediction is based on target’s current movements. The estimate is limited to one minute.
The information is provided with a line indicating the target’s course. The length of the line reflects its speed.
•  Bow Marker
This function displays a dotted line drawn from the bow of the vessel symbol. The line reflects your vessel’s current heading.
Do not confuse this line with the bearing line.
•  Current Vector
The Current Vector function shows you the speed and direction of the water current under your vessel. One or more arrow are drawn to or from the vessel symbol to indicate the properties of the sea currents. The direction of the arrows indicate the direction of the water currents. The length of the arrows reflects their speeds. Multiple arrows are used if the sensor presents information from more than one layer.
The Current Flow page allows you how to present the direction of the sea current. This page is located in the Display Options dialog box.
For this functionality to work, a current sensor must be connected to the SU90 system. The use of an ADCP (Acoustic Doppler Current Profiler) is recommended.
