See some videos here of our equipment in action:

  • Site visit for an analysis on the survey required and determine the best and safest way to carry out the works
  • Combined Topographic, Scanning (under bridges, water structures) and Bathymetric survey solutions
  • Ideal for those hard to reach areas, under bridges, canopy’s, small channels, lakes and canals.
  • Mobile unit can be deployed for difficult to reach areas by other larger vessels.
  • Using existing site control or establish new control by GPS or Total station techniques.
