Using markers in the CS90 user interface
Under normal use, the CS90 system presents several different echoes simultaneously. Some
of these are clearly more interesting than others. It can be a challenging task to tell these
echoes apart. It can also be hard to keep track of the different echoes as both echoes and
your own vessel move. To ease the identification of these echoes you can use
markers .
In this context, the phrase marker is used to identify a visual symbol placed in the
display presentation. Placing a marker on an echo identifies the echo as "interesting". It
is regarded as an
object that you can act upon.
Further classification of this echo as a target must be done manually.
The phrase target is used to identify an echo in the display 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 position or target tracking.
The CS90 offers several different marker types. You can add as many markers as you
like. The most common markers can be added using dedicated buttons on the Operating
Panel. Other markers are added using the shortcut menu in each view. Each marker is
identified with its geographical location.
Tip
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 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". If you change the tilt and bearing
settings manually, the priority status is lost.
