- Model VIY3-125 - 125 MHz, up to 15 m depth


The VIY2-125 ground penetrating radar (GPR) is used for location and analysis of underground anomalies using electromagnetic pulse radiation. The GPR is suitable for searching of both metal and dielectric targets (stratiform structures, pipes, voids, building constructions etc.).

VIY3-125 in utilities searching
  • Research of geological structures;
  • Search of pipes and communication objects; 
  • Examination of engineering construction (building basements, dams, etc.);
  • Investigation of man-caused accident areas;
  • Search of underground objects (voids, cracks, foreign inclusions, weak rocks);
  • Search of underground constructions (underground passages, sewers and so on);
  • Ground water level determination;
  • Subsurface deposits profiling;
  • Search for source of leakage from pipelines by indirect signs (excessive moisture). 

  • Measuring wheel and GPS are connected to antenna unit. The unit itself connects to laptop via WiFi or USB data cable. Thus, all components including antenna system, electronic modules, battery, and so on, are assembled in single case. This solution ensures that antennas and electronics are perfectly matched, the device is highly reliable and easy to use;
  • Spectrum randomizing (quasi-random sampling sequence) - interference immunity improvement especially to coherent influences;
  • Increased dynamic range owing to digitally traces stacking; 
  • Real time signal pre-processing;
  • Low power consumption - at least 8 hours working session without charging necessity;
  • Thanks to standard WiFi or USB connection, the user can choose any computer to work with VIY GPR. It can be either netbook, or modern models with a 12-core processor.
