Kongsberg Maritime EM 2040-04 Single RX (MKII)

MULTIBEAM ECHO SOUNDER

The EM 2040-04 Single RX MKII is a true wide band high resolution shallow water multibeam, an ideal tool for any high resolution mapping and inspection application.
Transducer heads are well suited for any type of installation, permanently, in hull or bow/side-mounted or on deep underwater vehicle
With the release of the EM 2040 MKII series, KONGSBERG MARITIME has upgraded the hardware and software to increase the swath and improve the data quality of the EM 2040 series.
