GV100 100MHz Frequency GPR

Monostatic screened impulse GPR system with built in controller for wireless connection to laptop / tablet. The GroundVue 100 is a monostatic shielded 100MHz central frequency antenna. The Antenna utilises a real time analogue to digital converter to provide unbeatable signal to noise at long two way time travels.

The Real time A//D enables the system to stack 7500 times per trace, giving a total of 24 bits data width, and improving the signal to noise ratio of late arrivals. the system has been designed for environmental studies and brownfield site investigations.

Applications

  • Depth of Peat.
  • Depth to bedrock.
  • Shallow cavity detection.

Data is transferred via wireless network or Bluetooth (please specify on order) to a Windows OS device. Goespatial positions can be integrated through the recording device. The intuitive and user interface means data acquisition is simple and quick.
