Own Ship Marker

Select Place Own Ship Marker to add a square symbol to the vessel’s current position in the echo presentation. The own ship marker is intended as a tool in a search situation.

To place the own ship marker:

  1. Press Own Ship Marker on the Operating Panel. (This function is not supported by all the operating panels.)

or:

  1. Right-click and select Place Own Ship Marker on the shortcut menu.

The own ship marker is now regarded as an object. All information about the object is shown in the Objects menu listed as "OSM". You can place as many own ship markers as you need.

Note:

The marker is stationary. If your vessel moves in the ST90 presentation the marker will not follow.

The own ship marker is intended as a tool in a search situation. Place the marker when your echo sounder confirms that you are passing over a school. Then, if you should loose the school from view, you will know where to start looking for it.

During a search your ST90 presentation may be cluttered with multiple markers and echoes. Due to its shape the own ship markers are easy to see among the other markers.
