The program has the convenient function of placing customized Markers at virtually any Location on any Chart. With a click of the mouse, identifiers such as Home Base, Lighthouses, Historic Sites, Buoys, Ports, Rocks, etc, can be placed on the Chart. The added option exists to create personalized Marker icons.
Marker Tools ![]()
appear on the Main Tool Bar. Note that by taking
the mouse pointer over the button, in one or two seconds a ToolTip will appear
with a description of what that button does.
Any image, text, pdf or any other kind of document can be Attached to the selected Marker.
To start creating a Marker, click the Create New Marker
icon in the Main Toolbar. While moving the mouse,
a Marker will move onscreen, along with the Marker's default name. Drag and
drop the Marker to the desired position on the chart in the Main
Chart View.
Note that if the Marker is to be added at a location not visible in the Main Chart View, first pan and zoom to the area required and then add the Marker there following the steps above.
Creating Marker using Coordinate Entry
First, create a Marker anywhere in the Main Chart View by using the mouse (see previous paragraph.)To specify the Marker's intended coordinate, right click on the newly created Marker and select Set Coordinate on the menu.

The following dialog box will appear. Type the exact coordinates for the Marker.

Once (new) coordinates are entered, the Marker shows at that location on screen in the Main Chart View.
There are two ways to delete a Marker.

Markers can be exported to GPS or to a file. To do so, right-click on the Marker
to bring up the menu. If connected to a GPS, there is the option of clicking
on Send to GPS or Export to File. If not connected to GPS, only Export to File
will be highlighted and this will be the only choice. A NavSim Object file with
the extension .nso will be created. This is a proprietary file format and can
contain any combination and number of object(s). Any number of the program users
can export and import such files for transporting data and for information-sharing
purposes.
