Ground Penetrating Radar 500 MHz, GPR
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(farmRead More
GP4 Ground Plane Antenna 4-Band 7/14/21/29M Boasts Excellent High Efficiency
