Equipment for echosounding Equipment LMS-337C DF echo sounder LMS-337C – compact dual frequency echo sounder with a color LCD screen for installation on small boats. Used as a navigation aid for operational control of the depth and sounding works in conditions of shallow and coastal sites. The screen displays in graphical form the bottom topography and samples of the depths and of the plane coordinates obtained from a GPS receiver.
