True motion

307670/D
When True motion mode is selected, the picture is locked to a
geographical position, where the vessel moves around the screen
according to its present course and speed. All echoes are always
presented in their correct position relative to the vessel, and their
movements on the screen will be a true representation of the
movements of the targets through the water. When the vessel
symbol reaches the edge of the screen, it will automatically be
moved back to the centre, or to a position determined by the
button on the Operating Panel. This position is reset to the
Centre
screen centre whenever the mode is changed. When you press
the button, the target will automatically be moved to
Target Track
the screen centre.
