The Humboldt Concrete GPR Scanner has been designed to find even the deepest targets while still providing high-resolution. The unit boasts the most diverse sensor suite on the market today. It can be used to locate rebar, power lines, cables, conduits, pipes, and voids. Dual-frequency GPR antennas insure high-resolution scans can be made without sacrificing penetration depth. The two GHz antennas clearly identify objects buried in concrete to depths of about two feet, while the 750 MHz antennas can detect objects as deep as 6 feet. This scanner also provides a dual mode power line detector that detects both current and voltage. This is useful for detecting power lines where no current is flowing. The system is controlled with a rugged IP67 Windows tablet computer that connects to the sensor via WiFi. There are several mounting configurations for the tablet to support one- or two-person teams. The unit has several survey configurations for maximum flexibility. A long handle can be attached for floor surveys. Finally, the long handle converts into a tripod for the tablet computer, in order to provide maximum freedom of the sensor head. The wireless design has eliminated all cables to improve ease of use, and eliminate common problems associated with connectors and cables. An innovative positioning system includes an odometer, GPS, as well as optional inertial measurements. Advance software is available to provide cross section views (B-Scans), depth slice views, and 3D views.
