Innomar SES-2000 autonomous Sub-Bottom Profiler

Innomar SES-2000 autonomous parametric sub-bottom profiler Innomar's parametric sub-bottom profilers are often used in shallow and extremely shallow waters with limited access for vessels and boats. To support such surveys Innomar offers a remotely operated surface vehicle pre-configured with the Innomar SES-2000 smart SBP. This vehicle can be used to survey a pre-defined area automatically or to work in protected areas like drinking-water reservoirs. It is also possible to integrate third-party equipment, such as ADCP, MBES or sidescan sonars.
