In this context, the phrase marker is used to identify a visual symbol placed in the ST90 presentation. By placing a marker on the echo it is regarded as an object that you can act upon. If relevant, you can further classify the object as a target.
The phrase target is used to identify an echo in the ST90 presentation that you wish to act upon. The echo may be from a material item, a shallow, reef or rock, or from fish, fish schools or mammals. You must decide which echoes that shall be classified as targets, and wether you shall start target tracking.
If you have placed markers on several echoes to make them objects, you can select one of these and give it priority status. The bearing line in the relevant ST90 views will automatically be locked on the object with this priority to reflects its bearing. Only one single object can be given priority status. The priority is identified with a "P".
•  Initiate Track
During normal operation, some echoes are clearly more interesting than others. In many situations specific echoes may be regarded as targets, and it can be useful to receive continuous information about the location, speed and heading of such targets. To set up the ST90 to provide such information, you can start target tracking.
The Initiate Track function allows you to manually start target tracking.
Place the cursor over the echo you wish to track. Select Initiate Track. The tracked target is regarded as an object, and it is identified with a circle and two lines. The bearing line is automatically locked on the object to reflects its bearing. A new tracked object is automatically given priority status. If another object has this priority, the status is transferred to the new object. The priority is identified with a "P".
•  Place Marker
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.
•  Delete Marker
Delete Marker allows you to delete a marker from the current view. Select Delete Marker.
•  Set Priority Marker
One marker can be given priority status to identify the object as the most important target or position. If another object has this priority, the status is transferred to the new object. The priority is identified with a "P" When a marker is given priority it can be regarded as a position track. Relevant information about the priority object can be found in the lower left corner of the view.
•  Place Own Ship Marker

You can only add one circle marker to the ST90 presentation.
