Geophysical Survey Systems (GSSI) has updated its UtilityScan ground-penetrating radar system to include 3-D data collection and playback mode for the UtilityScan DF model that provides X-ray-like imagery of the ground in addition to the standard two-dimensional mode. It can be used to locate metallic and nonmetallic objects and features a dual-frequency antenna and touch-screen monitor to allow users to simultaneously view shallow and deep targets. New software features allow the user to input colored markers while using a GPS unit to aid in subsurface target classification. 800/524-3011; www.geophysical.com.
