In this context, the phrase marker is used to identify a visual symbol placed in the SN90
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 SN90 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 whether 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 SN90 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 SN90 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".
