Ground Penetrating Radar (GPR). Public utility systems and local governments require that the positions of underground systems are located and marked. This helps in planning projects and avoiding risks and hazards. The LMX200™ builds on the capabilities of the LMX100™ and adds further features to help you locate and map these utilities. It adds the powerful Grid Scan mode and the ability to use an external GPS to take full advantage of SplitView and MapView. The LMX200™ allows data export for easy project archiving as well as post-processing and report generation with the optional EKKO_Project GPR data analysis software.
