    description:   The EM 300 multibeam echo sounder is designed to do mapping from 10 m depth to beyond the continental rises, including the shallower ocean basins. It operates down to more than 5000 m depth with swath widths up to about 5000 m. Small transducers and compact electronics make the installation easy, and the system accuracy is generally well within the IHO standards. The EM 300 is a complete system. All necessary sensor interfaces, data displays for quality control and sensor calibration, seabed visualization, and data logging are a standard part of the system, as is integrated seabed acoustical imaging capability (sidescan). The nominal sonar frequency is 30 kHz with an angular coverage sector of up to 150 degrees and 135 beams per ping as narrow as 1 degree. Achievable swath width on a flat bottom will normally be up to 5.5 times the water depth. The angular coverage sector and beam pointing angles may be set to vary automatically with depth according to achievable coverage. This maximizes the number of usable beams. The beam spacing is normally equidistant with equiangle available. The EM 300 multibeam system was in production from 1997 to 2007 and was replaced with the EM 302.
