Kongsberg Maritime EM 2040CX Dual

MULTIBEAM ECHO SOUNDER

The EM 2040CX Dual is a shallow water multibeam echosounder based on the EM 2040 technology.
It is an ideal tool for any high-resolution inspection and mapping applications, and with two small circular transducer head it's well suited for any type of installation, portable or permanently or underwater vehicles.
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.
