... main features ...
The multi-beam depth finder transmits a sound beam into a fan form and can acquire sounding data for an aspect as three-dimensional data while receiving it. I can grasp the underwater structure and topography visually and generally and can show an effect in marine topography investigation, disaster, accident investigation, management of the harbor construction, i-Construction in the harbor.
Kongsberg EM2040
●The sounding in middle depth sea areas 400m or more is possible by transmitting an FM chapu wave
●By a noise reduction function of the seafloor topography information system, the real-time data cleaning of sounding data is possible

Seabat T50-P
●I incline the sonar 15 degrees and make rigging, and a measurement is possible to the surface of the water neighborhood by tipping a beam on software.
●It increases measurement scores by catching plural points in a 1 sound borderline using a multi-detect function and can perform the measurement that evaded the complicated topography or school of fish.
●I raise the density in the range of the option in suwasu by using a flexible mode function and can measure subjects of survey in detail
