Indications and markers on the echo sounder 1 display
Trackball mark position reference mark
The trackball mark position reference mark, a solid circle, is inscribed on the
ship's track when the trackball mark is placed in the echo sounder display. Its
purpose is to show corresponding trackball mark position on the horizontal
display. It changes position with trackball mark position and tilt range, and
disappears when its position is no longer within the range of the echo sounder
display. This mark does not appear when the distance to the trackball mark is
longer than the track length. Own ship's speed data is required for this function.
