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.
