Single-masted 3D bulldozer guidance system + SP14 inertial sensor. The Leica iCON iGD3 3D guidance system with single mast mounted centrally on the blade not only improves productivity, it also offers an unprecedented degree of flexibility. The 3D system allows you to work independently and with precision everywhere on the project while guided by a GNSS system or by a Leica Geosystems totally robotized station. Used in tandem with a Leica SP14 inertial incline sensor, this solution offers a grading of great precision on inclined surfaces, amongst others.
