| Definition | A 40 kHz ping-rate multibeam echosounder designed for high resolution seabed mapping and inspection. The EM 3000 can be configured to use single (3000S) or dual (3000D) transducers. The dual transducer system increases the shallow-water coverage up to 10-x the water depth, and increases the number of measurements per ping from 120 to 220. The system features a Processing Unit (PU) which performs the beamforming and bottom detection, and further controls the gain, ping rate and pitch compensation of the transmit beam. The PU is available as two versions; one for surface use and one for subsea use. It has an operating depth from 1 to 150 m below its transducers. It allows use on survey launches and subsea vehicles to 1500 m water depth. It features a 1.5 degrees beam width and an operating frequency of 300 kHz. It has a maximum swath width 200 m in deep water, while for shorter ranges the swath width maybe up to about four times water depth. | ||
