GSSI announced its StructureScan Mini series, ideal for the concrete inspection industry. The StructureScan Mini is a handheld, all-in-one GPR system for locating rebar, conduits, post-tension cables and voids, and can be used to determine concrete slab thickness in real-time. The StructureScan Mini is available in two models: the standard StructureScan Mini, and the StructureScan Mini HR, a high-resolution system. The StructureScan Mini is 1600 MHz and can reach depths of up to 20 inches; the StructureScan Mini HR offers a 2600 MHz antenna for high-resolution data and can reach depths of up to 16 inches. Both systems safely locate metallic and non-metallic targets, with an auto target feature that marks the detection of features of interest. Both the standard and HR systems are available with either standard 2D capabilities, or 3D for an x-ray-like image. The lasers on the side of the unit indicate the exact location of the center of target for accurate marking of targets embedded in the concrete.
