Based on parametric acoustic principle, GeoInsight 100 features not only single beam sub-bottom profiling (bathymetry and 2D sediment waterfall), but also phased multibeam for wideband survey. The user can set up gain compensation, filter tracking, secondary frequency profiling in its standard software. 2D sediment data can be mosaicked into 3D seabed view for quick subsea site investigation and buried target inspection.
The whole system is manufactured in China with competitive specifications in the market. With wide selection of secondary frequency and short wavelength, GeoInsight can inspect small buried target under seabed. The 3D imagery makes it ideal for quick offshore site survey and analysis.
