500 MHz shilded UWB, Short-Pulse Ground Penetrating Radar. The GPR must be mounted on a cart and needs a flat ground surface. The offer does not include a cart. It is suitable for investigating flat pavement, asphalt and concrete. The maximum penetration depth is up to 2 meters, usually up to 1 meter. GPR technology is suitable for detecting anomalies in high-resistance environments such as rocks, asphalt, concrete or very dry sand, cavities covered with stones or bricks. Radio waves do not penetrate well in low-resistance environments, but normal soil(farm and garden soil) is a medium of low resistance, so GPR technology does not penetrate the farm and garden soil. Depth penetration is a function of antenna frequency and the electrical conductivity of the soils in the survey area. Lower frequency antennas achieve greater depth penetration compared with higher frequency antennas but with poorer spatial resolution. GPR is best suited for low conductivity or high resistivity materials like sandy soils, limestone and granite. The GPR is 8bit, time windows 25nS, 50nS, 100nS maximum depth in masive hard rocks 2m for large cavities. 500 MHz shilded GPR, dimensions 31x26x13 centimeters (0.31×0.26×0.13 meters), (12.2 x 10 x 5.1 inches). 2D visualisation software and manual. To use the GPR, you need Windows laptop, cart and lead acid battery 12V 1.2Ah. KIT GPR NOT included Windows laptop, cart and battery 12V 1.2Ah. This is valid when I do not have an GPR ready for sale.
