Now full advantage can be taken of the Ethernet data produced by the Echotrac series of sounders. eChart allows the user to control all of the parameters of the echo sounder, display the data in a number of formats (color and gray shades), even print and apply filters. Raw data is stored in .DSO format, a non-proprietary format that is easily compressed or converted to .XTF for additional processing.
