- Model VIY3-700 - 700 MHz, up to 2.5 meters depth


The VIY3-700 Ground Penetrating Radar (GPR) can be used for location and analysis of underground objects using electromagnetic pulse radiation up to 2.5 meter depth (or thickness). The VIY3-700 GPR is suitable for searching of both metal and dielectric objects (pipes, communications, voids, building constructions, etc.)

  • Engineering and communication objects searching
  • Engineering construction examination (building basis, dams, etc.)
  • Man-caused accident areas investigation
  • Search of reinforcement rods in building unit
  • Search of hiding places and other building in objects

  • Measuring wheel (Odometer) and GPS can be connected directly to antenna unit;
  • All components including antenna system, electronic modules, battery, and so on, are assembled in a single fiberglass case;
  • Battery, in order to facilitate the antenna unit, is designed in separate case;
  • Antenna unit is connected to laptop by USB data cable through the battery case. This solution ensures perfect matching of antenna and electronics, the device is highly reliable and easy to use;
  • Battery case can be placed in the operator's backpack or mounted on a Cart-36 handcart;
  • Antenna unit can be pulled with a transport belt (along the ground) or holding by the handle (along the wall);
  • Spectrum randomizing (quasi-random sampling sequence) - the improved interference immunity, especially against the coherent interferences;
  • Increased dynamic range due to digital traces-stacking;
  • Real time signal pre-processing;
  • Low power consumption - at least 8 hours working session without charging;
  • With standard WiFi or USB connection, the user can choose any computer to work with VIY GPR. It can be either netbook, or modern models of laptops with a 12-core processor.

  • Antenna frequency: 700 MHz
  • Analogue-to-Digital Converter range:  18 bit
  • Dynamic range: at least 135 dB
  • Data acquisition rate:  up to 146 traces per second
